Cosmic cliffs and dancing galaxies: Webb begins new era of astronomy

The cosmic cliffs of a stellar nursery, a quintet of galaxies bound in a celestial dance: the James Webb Space Telescope released its next wave of images Tuesday, heralding a new era of astronomy.

“Every image is a new discovery,” said NASA administrator Bill Nelson. “Each will give humanity a view of the universe that we’ve never seen before.”

Released one by one, the new images demonstrated the full power of the $10 billion observatory, which uses infrared cameras to gaze into the distant universe in unprecedented clarity.

On Monday, Webb revealed the clearest image to date of the early universe, going back 13 billion years.

The latest tranche included the “mountains” and “valleys” of a star-forming region called NGC 3324 in the Carina Nebula, dubbed the “Cosmic Cliffs,” 7,600 light years away.

“For the first time we’re seeing brand new stars that were previously completely hidden from our view,” said NASA astrophycisist Amber Straughn.

Webb also revealed never before seen details of Stephan’s Quintet, a grouping of five galaxies including four that experience repeated close encounters, which provide insights into how early galaxies formed at the start of the universe.

The telescope dramatically captures shockwaves as one of the galaxies smashes through the center of the cluster.

A dim star at the center of the Southern Ring Nebula was revealed for the first time to be cloaked in dust, as it spews out rings of gas and dust in its death throes.

Understanding the molecules present in such stellar graveyards can help scientists learn more about the process of stellar death.

– Exploring the cosmos –

The telescope also found water vapor in the atmosphere of a faraway gas planet. The spectroscopy — an analysis of light that reveals detailed information — was of planet WASP-96 b, which was discovered in 2014.

Nearly 1,150 light-years from Earth, WASP-96 b is about half the mass of Jupiter and zips around its star in just 3.4 days.

“We’ve seen the effect of what happens when a planet and its atmosphere passes in front of the star, and the star light filters through the atmosphere, and you can break that down into wavelengths of light,” said NASA’s Knicole Colon.

“So you’re actually seeing bumps and wiggles that indicate the presence of water vapor in the atmosphere of the planet.”

Launched in December 2021 from French Guiana on an Ariane 5 rocket, Webb is orbiting the Sun at a distance of a million miles (1.6 million kilometers) from Earth, in a region of space called the second Lagrange point.

Here, it remains in a fixed position relative to the Earth and Sun, with minimal fuel required for course corrections. 

A wonder of engineering, the total project cost is estimated at $10 billion, making it one of the most expensive scientific platforms ever built, comparable to the Large Hadron Collider at CERN.

Webb’s primary mirror is over 21 feet (6.5 meters) wide and is made up of 18 gold-coated mirror segments. Like a camera held in one’s hand, the structure must remain as stable as possible to achieve the best shots.

After the first images, astronomers around the globe will get shares of time on the telescope, with projects selected competitively through a process in which applicants and selectors don’t know each other’s identities, to minimize bias.

Thanks to an efficient launch, NASA estimates Webb has enough propellant for a 20-year life, as it works in concert with the Hubble and Spitzer space telescopes to answer fundamental questions about the cosmos.

Euro drops to dollar parity as eurozone recession fears mount

The euro struck parity with the dollar for the first time in nearly 20 years on Tuesday as a cut in Russian gas supplies to Europe heightened fears of a recession in the eurozone.

The European single currency hit exactly one dollar — its lowest level since December 2002 — before bouncing back to as high as $1.0070.

Oil prices plunged on concerns of a wider recession as central banks hike interest rates to fight decades-high inflation, with both main contracts falling back under $100 per barrel at one point.

While European stocks initially moved lower, they rallied in afternoon trading to finish higher. Wall Street’s main stock indices were also up in late morning trading.

“Rising inflation, stalling economic growth and more recently fears that Russia could cut gas supplies have pulled the euro lower,” said Fiona Cincotta at City Index.

“The nail in the coffin today was dire data showing that economic confidence in Germany fell to a decade low,” she added.

Russian energy giant Gazprom on Monday began 10 days of maintenance on its Nord Stream 1 pipeline — with Germany and other European countries watching anxiously to see if the gas comes back on.

“The gas crisis has really spooked markets over the eurozone economy,” Markets.com analyst Neil Wilson told AFP.

With relations between Russia and the West at their lowest in years because of the invasion of Ukraine, Gazprom may not reopen the valves, according to analysts.

“The next few weeks could be challenging for Europe, with possibly maximum uncertainty stretching into August,” said SPI Asset Management’s Stephen Innes.

“Investors increasingly believe that gas may not start to flow through Nord Stream 1 again following the scheduled maintenance on July 11-21, with further ‘temporary’ interruptions seen as likely.”

Worries about a Covid flare-up in China — fuelling fears of more lockdowns — added to the downbeat mood, just as investors prepared for a week of economic data and corporate earnings that could have huge implications for markets.

A forecast-beating US jobs report last week suggested the world’s top economy was coping with higher Federal Reserve rates, but it also gave the central bank more room to continue tightening — leading to concerns it could go too far and cause a contraction.

The European single currency is also under pressure from the Federal Reserve hiking US interest rates more aggressively than the European Central Bank.

The dollar has jumped 14 percent against the euro since the start of the year.

US inflation data due out Wednesday could also solidify the case for the Fed to continue raising interest rates aggressively.

“In anticipation of that, investors have retreated to the safety of the US dollar once more, steering clear of risky assets in favour of haven” assets, said market analyst Craig Erlam at trading platform OANDA.

Central banks have been increasing borrowing costs in a bid to tame inflation, which has been fuelled by soaring energy prices.

Oil and gas prices have rocketed this year after economies reopened from Covid lockdowns and following the invasion of Ukraine by major energy producer Russia, which raised concerns whether supplies will be adequate.

Russia and Ukraine to hold Black Sea grain talks in Turkey

Russian and Ukrainian delegations were due to meet with UN diplomats in Istanbul on Wednesday in a bid to break a months-long impasse over stalled grain deliveries across the Black Sea.

The four-way meeting with Turkish officials comes as food prices soar around the world due to Russia’s invasion of Ukraine.

Ukraine is one of the world’s biggest exporters of wheat and other grain.

But its shipments have been blocked by Russian warships and mines that Kyiv has laid across the Black Sea.

NATO member Turkey — on good terms with both Russia and Ukraine — has spearheaded efforts to resume the grain deliveries.

Turkish officials say they have 20 merchant ships waiting in the Black Sea that could be loaded quickly with Ukrainian grain.

Turkish Defence Minister Hulusi Akar said on Tuesday that the meeting would involve the three countries’ military delegations and a team from the United Nations.

“Military delegations from the Turkish, Russian and Ukrainian defence ministries, and a delegation of the United Nations, will hold talks tomorrow in Istanbul on the safe shipment to international markets of grain waiting in Ukrainian ports,” Akar said.

– ‘Still a way to go’ –

A Russian foreign ministry spokesman stressed that Moscow was entering the meeting with a list of firm demands.

“Our understandable conditions include the possibility to control and search the ships to avoid the contraband of weapons, and Kyiv’s commitment not to stage provocations,” ministry spokesman Pyotr Ilyichev was quoted as saying by Russia’s Interfax news agency

The Russian spokesman added that the UN team would act as “observers” at the talks.

But Ukraine stressed the UN’s importance to the negotiations and said it wanted its own set of security guarantees.

“We are grateful to UN Secretary-General Antonio Guterres for his active role in reaching for a solution that could guarantee the security of our southern regions,” Ukrainian foreign ministry spokesman Oleg Nikolenko told Interfax-Ukraine.

Guterres played down expectations heading into the talks.

“We are working hard indeed, but there is still a way to go,” the UN chief told reporters.

– Putin-Erdogan talks –

Turkish President Recep Tayyip Erdogan has tried to use his good relations with Russian counterpart Vladimir Putin and Kyiv’s Western-backed leaders to thrust Ankara into the centre of negotiations about Ukraine.

Erdogan is due to meet Putin for the first time since Russia’s invasion when the two leaders are hosted by Iranian President Ebrahim Raisi in Tehran next Tuesday.

The talks are officially due to focus on the situation in war-ravaged Syria.

But the Kremlin said Putin and Erdogan will also hold a separate meeting that is almost certain to focus heavily on Ukraine.

Turkey has been sending defence delegations to both Moscow and Kyiv in a bid to break the deadlock over Ukraine’s grain.

A plan proposed by the United Nations would see the shipments start along specific corridors that avoid known locations of mines.

– Snake Island –

Ukraine has refused to de-mine the area out of fear that Russia might then stage an amphibious assault on cities such as the Black Sea port of Odessa.

Ukraine’s port authority said last week that Kyiv’s recapture of Snake Island in the Black Sea has allowed it to resume shipments into neighbouring Romania along the Danube River.

But those deliveries can only cover a small fraction of the 20 to 25 million tonnes of grain believed to be blocked in Ukraine.

The negotiations are complicated by mounting suspicions that Russia is stealing and exporting grain from farmers in Ukrainian regions now under its control.

Ukraine summoned Ankara’s ambassador to Kyiv after Turkey last week failed to seize a Russian-flag ship suspected of carrying confiscated grain.

The ship returned to a Russian port after spending nearly a week anchored off Turkey’s Black Sea coast.

Ukraine’s foreign ministry said it was “deeply disappointed” with Turkey.

UN Security Council passes 6-month extension of cross-border Syria aid

The UN Security Council adopted a resolution Tuesday extending a system for cross-border aid to Syria by six months, the duration demanded by Russia while other members had sought a full year.

The measure received support from 12 of the Security Council’s 15 members, including Russia, China, and the grouping’s 10 non-permanent members.

Western nations had called for a year-long extension, arguing that six months was insufficient to properly plan the delivery of aid to war-ravaged Syria.

Britain, France and the United States abstained from the vote, marking their disagreement with the shorter duration.

“Russia forced everyone’s hand: either the system would be ended, or it was extended for six months,” an ambassador told AFP, requesting anonymity to discuss the extension agreement reached in principle on Monday between the council’s 15 members. 

“We could not let people die.”

United Nations Secretary-General Antonio Guterres expressed similar concern, saying extending the aid — particularly for the people of Idlib in Syria’s rebel-held northwest — “is a matter of life and death for many of them.” 

“We asked for a renewal of one year. The Security Council approved six months,” he said. “But I strongly hope that after six months it will be renewed.”

The aid delivery mechanism across Turkey’s border into rebel-held Syria at the Bab al-Hawa crossing is the only way UN assistance can reach civilians without navigating areas controlled by Syrian government forces.

The system, in place since 2014 and which more two million people rely on for assistance, had expired on Sunday.

The agreement, introduced by Ireland and Norway, breaks an impasse that had threatened to derail the life-saving supplies.

It also provides for a renewal in January 2023 for another six months, subject to the adoption of a new resolution, diplomats said.

– ‘Outrageous’ –

Both Ireland and Norway expressed relief Tuesday that aid would continue to flow.

But non-governmental groups offered withering critiques of Russia and slammed the United Nations process as unsustainable and inadequate.

“It’s outrageous that Russia once again succeeded in blackmailing Council members, this time by slashing the renewal period to six months so that the authorization expires in the middle of winter,” Human Rights Watch said in a statement.

British-founded charity Oxfam said the system of repeated renewals of short-term aid windows places unnecessary uncertainty on an already precarious situation for vulnerable Syrians.

The resolution “is deeply disappointing and could potentially leave more than four million people in northwest Syria without the assistance they depend upon to survive when the harsh winter months arrive,” said Oxfam’s Brenda Mofya.

In contrast, the World Health Organization hailed the UN for voting to avoid a near-total cut off of vital aid, saying they will continue to deliver “life-saving supplies” to the vulnerable population.

The renew of cross-border aid operations “is very good news for the nearly four and a-half million Syrians whose lives and health depend on this humanitarian access,” WHO chief Tedros Adhanom Ghebreyesus told reporters in Geneva.

Russia, a Damascus ally, vetoed a Security Council resolution Friday that would have prolonged the mechanism by one year. Western powers then voted down Moscow’s initial competing resolution that proposed extending approval by just six months.

The new Irish-Norwegian text provides for a renewal in January 2023 for another six months, subject to the adoption of a new resolution.

More than 4,600 aid trucks, carrying mostly food, have crossed Bab al-Hawa this year, helping some 2.4 million people, according to the UN’s Office for the Coordination of Humanitarian Affairs.

Kyiv 'destroys' Russian arms depot, as EU, US pledge nearly $3 bn

Kyiv said Tuesday it had launched artillery barrages that a destroyed a Russian arms depot and carried out a “special operation” to free military captives in the Moscow-controlled Kherson region.

The bombardments in the south came as Washington and the EU announced nearly $3 billion combined for Ukraine and Turkey said delegations from Moscow and Kyiv would meet in Istanbul Wednesday to discuss restarting stalled grain deliveries across the Black Sea.

Ukrainian military officials said the strikes had destroyed artillery, armoured vehicles “and a warehouse with ammunition” in the town of Nova Kakhovka.

Russian-backed authorities accused Ukraine, however, of damaging civilian infrastructure and killing at least seven people, a toll that could not be independently verified.

“Warehouses were hit, as were shops, a pharmacy, petrol stations and even a church,” the head of the city’s Moscow-backed administration, Vladimir Leontiev, said on social media.

Ukrainian military intelligence said separately its forces had free five captives in a “special operation” in Kherson, including a military serviceman and former police officer, without specifying when.

The Ukrainian army has for several weeks been waging a counter-offensive to recapture Kherson, which was taken by Russian troops early in the February invasion of Ukraine.

The deputy head of the pro-Russian authorities in Kherson, Ekaterina Gubareva, said Ukraine had used long-range, precision artillery systems supplied by the United States in the strikes in Nova Kakhovka.

– Western financial aid –

Military analysts are crediting newly arrived systems from the West — including HIMARS from the United States — with attacks deeper into Russian-controlled territory across the front line.

EU member states, which have been supplying Ukraine with military support, on Tuesday approved one billion euros ($1 billion) in financial support for Kyiv, billing it as the first instalment of a promised nine-billion-euro rescue package agreed in May.

The United States separately announced $1.7 billion to Ukraine to help fund the country’s recovery from Russia’s invasion.

“This aid will help Ukraine’s democratic government provide essential services for the people of Ukraine,” Treasury Secretary Janet Yellen said of the funds that are part of a $7.5 billion aid package signed by President Joe Biden in May.

Moscow was striking back across Ukraine, with officials in the southern city of Mykolaiv saying Russian forces had bombed two medical facilities and homes, injuring 12 people.

Six people were injured in Russian shelling on Ukraine’s second city Kharkiv, said regional governor Oleg Synegubov, after strikes the previous day left seven dead across that region.

But the heaviest fighting in recent weeks has centred on the Donbas where Moscow’s forces have slowly advanced under fierce resistance since failing to capture Kyiv after the February 24 invasion.

Ukrainian emergency services said the death toll had risen to 38, two days after Russian bombardment flattened a residential building in the eastern town of Chasiv Yar, in the Donetsk region of the Donbas.

In Bakhmut — one of the few remaining cities under Ukrainian control in Donbas — AFP journalists could hear nearby artillery fire.

– Toll rises to 38 –

“The front is getting closer,” said municipal official, Dmytro Podkuyidko, estimating that more than one-third of the town’s population of 73,000 have fled.

“If it gets worse, I’ll end up leaving too,” Podkuyidko said.

Turkey announced meanwhile that Russian and Ukrainian delegations had agreed to meet in Turkey Wednesday for talks to break an impasse on allowing Ukrainian grain to leave its southern ports which are mined and blocked by Russian warships. 

The four-way meeting with Turkish officials and the United Nations comes as food prices soar around the world due to Russia’s invasion of Ukraine.

Turkish President Recep Tayyip Erdogan is due to meet Russian leader Vladimir Putin for the first time since the invasion at talks hosted by Iranian President Ebrahim Raisi in Tehran next Tuesday.

The talks are due to focus on the situation in war-ravaged Syria, but the Kremlin said Putin and Erdogan will hold a separate meeting that is almost certain to focus heavily on Ukraine.

The Kremlin has been working to consolidate its hold over territories it controls like Kherson, both militarily and bureaucratically since the beginning of the conflict.

After Putin on Monday passed a decree fast-tracking Russian passports for all Ukrainians, Foreign Minister Sergei Lavrov was expected Tuesday to open a representative office for separatist authorities in Moscow.

Indonesian islanders sue cement giant Holcim over climate damage

Residents of Pulau Pari, an Indonesian island threatened by rising sea levels, are suing cement giant Holcim over its carbon dioxide emissions, a Swiss charity said on Tuesday.

“Holcim… bears a significant share of the responsibility for the climate crisis as well as for the situation on… Pari,” Yvan Maillard Ardenti, climate expert at Swiss Church Aid (HEKS), said on the charity’s website.

The complaint was lodged on Monday with a conciliation authority in Zug, Switzerland, where Holcim’s headquarters are located.

The four plaintiffs told German TV channel RTL on Monday they were seeking compensation from Holcim for damage already caused to their island by climate change, money for flood defences and a rapid reduction in the company’s carbon emissions.

“Holcim is globally the leading manufacturer of cement, the basic material for concrete, and one of the 50 biggest CO2 emitters out of all companies worldwide,” HEKS said.

This is in line with the 2021 greenhouse polluters index compiled by the University of Massachusetts Amherst, which ranks “LafargeHolcim” 47th among the top 100 emitters of climate-heating gases.

Contacted by AFP, Holcim, which merged with France’s Lafarge in 2015, declined to comment on the legal case but said it “takes climate action very seriously”. 

“This is the first time that a Swiss company will be held legally accountable for its role in climate change,” HEKS said.

The Swiss NGO is backing the islanders’ campaign alongside the Berlin-based rights group ECCHR and Indonesian environmental pressure group WALHI.

They point out that countries of the South are bearing the brunt of a climate emergency mainly created by the rich countries of the North.

Large portions of Pari, which depends on fishing and tourism, were likely to be under seawater in 30 years, HEKS said.

Holcim sold its Indonesian activities to local cement maker Semen Indonesia in 2019.

But globally, it emitted more than seven billion tonnes of CO2 emissions between 1950 and 2021, according to a new study from the US-based Climate Accountability Institute.

That amounts to more than twice the emissions of Switzerland since the year 1750, HEKS said.

“We significantly reduced our footprint over the last decade and will cut it further by 2030,” Holcim told AFP.

“We are focused on supporting our customers to build more with less to improve living standards for all while reducing emissions.”

Scientists find oldest Martian meteorite's original home

Scientists announced Tuesday they had found the crater from which the oldest known Martian meteorite was originally blasted towards Earth, a discovery that could provide clues into how our own planet was formed.

The meteorite NWA 7034, nicknamed Black Beauty, has fascinated geologists since it was discovered in the Sahara Desert in 2011.

It fits easily in the hand, weighing just over 300 grams (10.6 ounces), and contains a mix of materials including zircons, which date back nearly 4.5 billion years.

“That makes it one of the oldest rocks studied in the history of geology,” Sylvain Bouley, a planetary scientist at France’s Paris-Saclay University, told AFP.

Its journey dates back to the solar system’s infancy, “about 80 million years after the planets began forming”, said Bouley, who co-authored a new study on the meteorite.

Tectonic plates long ago covered up Earth’s ancient crust, meaning that “we have lost this primitive history of our planet”, Bouley said.

But Black Beauty could offer “an open book on a planet’s first moments”, he added.

To open that book, a team of researchers at Australia’s Curtin University set out to find the meteorite’s original home on Mars.

They knew that it was likely an asteroid hitting the red planet that sent Black Beauty shooting up into space.

The impact “had enough force to eject the rocks at very high speed — more than five kilometres (three miles) a second — to escape the Martian gravity”, Curtin’s Anthony Lagain, the lead author of the study in Nature Communications, told AFP.

Such a crater would have to be massive — at least three kilometres in diameter.

The problem? The pockmarked surface of Mars has around 80,000 craters at least that big.

– Following the clues –

But the researchers had a clue: by measuring Black Beauty’s exposure to cosmic rays, they knew it was dislodged from its first home around five million years ago.

“So, we were looking for a crater that was very young and large,” Lagain said.

Another clue was that its composition showed it had suddenly heated up around 1.5 million years ago — likely by the impact of a second asteroid.

The team then created an algorithm and used a supercomputer to trawl through images of 90 million craters taken by a NASA satellite.

That narrowed it down to 19 craters, allowing the researchers to rule out the remaining suspects.

They found that Black Beauty was dug up from its first home by an asteroid that struck around 1.5 billion years ago, forming the 40-kilometre Khujirt crater.

Then a few million years ago, another asteroid hit not far away, creating the 10-kilometre Karratha crater and shooting the Black Beauty towards Earth.

The region in Mars’ southern hemisphere is rich in the elements potassium and thorium, just like Black Beauty.

Another factor was that Black Beauty is the only Martian meteorite that is highly magnetised.

“The region where Karratha was found is the most magnetised on Mars,” Lagain said.

Known as the Terra Cimmeria—Sirenum province, it is “a relic of the early crustal processes on Mars, and thus, a region of high interest for future missions,” the study said.

Bouley pointed to a “bias” in the currently planned missions to Mars in favour of searching for signs of water and life.

But to understand how planets first form would answer some fundamental questions, Lagain said, including “how Earth became such an exceptional planet in the Universe”.

Turkey to host Russia-Ukraine-UN grain talks

Turkey said it will host Russian and Ukrainian delegations with UN diplomats on Wednesday to discuss the resumption of stalled grain deliveries across the Black Sea.
