Far out: NASA space telescope’s 1st cosmic view goes deep

Our view of the universe just expanded: The first image from NASA’s new space telescope unveiled Monday is brimming with galaxies and offers the deepest look of the cosmos ever captured.
The first image from the $10 billion James Webb Space Telescope is the farthest humanity has ever seen in both time and distance, closer to the dawn of time and the edge of the universe. That image will be followed Tuesday by the release of four more galactic beauty shots from the telescope’s initial outward gazes.
The “deep field” image released at a White House event is filled with lots of stars, with massive galaxies in the foreground and faint and extremely distant galaxies peeking through here and there. Part of the image is light from not too long after the Big Bang, which was 13.8 billion years ago.
“We’re going to give humanity a new view of the cosmos,” NASA Administrator Bill Nelson told reporters last month in a briefing. “And it’s a view that we’ve never seen before.”
The images on tap for Tuesday include a view of a giant gaseous planet outside our solar system, two images of a nebula where stars are born and die in spectacular beauty and an update of a classic image of five tightly clustered galaxies that dance around each other.
The world’s biggest and most powerful space telescope rocketed away last December from French Guiana in South America. It reached its lookout point 1 million miles (1.6 million kilometers) from Earth in January. Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool.
The plan is to use the telescope to peer back so far that scientists will get a glimpse of the early days of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus.
Webb is considered the successor to the highly successful, but aging Hubble Space Telescope. Hubble has stared as far back as 13.4 billion years. It found the light wave signature of an extremely bright galaxy in 2016. Astronomers measure how far back they look in light-years with one light-year being 5.8 trillion miles (9.3 trillion kilometers).
“Webb can see backwards in time to just after the Big Bang by looking for galaxies that are so far away that the light has taken many billions of years to get from those galaxies to our telescopes,” said Jonathan Gardner, Webb’s deputy project scientist said during the media briefing.
How far back did that first image look? Over the next few days, astronomers will do intricate calculations to figure out just how old those galaxies are, project scientist Klaus Pontoppidan said last month.
The deepest view of the cosmos “is not a record that will stand for very long,” Pontoppidan said, since scientists are expected to use the telescope to go even deeper.
Thomas Zurbuchen, NASA’s science mission chief said when he saw the images he got emotional and so did his colleagues: “It’s really hard to not look at the universe in new light and not just have a moment that is deeply personal.”
At 21 feet (6.4 meters), Webb’s gold-plated, flower-shaped mirror is the biggest and most sensitive ever sent into space. It’s comprised of 18 segments, one of which was smacked by a bigger than anticipated micrometeoroid in May. Four previous micrometeoroid strikes to the mirror were smaller. Despite the impacts, the telescope has continued to exceed mission requirements, with barely any data loss, according to NASA.
NASA is collaborating on Webb with the European and Canadian space agencies.
“I’m now really excited as this dramatic progress augurs well for reaching the ultimate prize for many astronomers like myself: pinpointing “Cosmic Dawn” — the moment when the universe was first bathed in starlight,” Richard Ellis, professor of astrophysics at University College London, said via email.

Sweltering heat across Asia was 45 times more likely because of climate change, study finds

ENGALURU, India: Sizzling heat across Asia and the Middle East in late April that echoed last year’s destructive swelter was made 45 times more likely in some parts of the continent because of human-caused climate change, a study Tuesday found.
Scorching temperatures were felt across large swaths of Asia, from Gaza in the west — where over 2 million people face clean water shortages, lack of health care and other essentials due to Israeli bombardment — to the Philippines in the southeast, with many parts of the continent experiencing temperatures well above 40 degrees Celsius (104 degrees Fahrenheit) several days in a row.
The study was released by the World Weather Attribution group of scientists, who use established climate models to quickly determine whether human-caused climate change played a part in extreme weather events around the world.
In the Philippines, scientists found the heat was so extreme it would have been impossible without human-caused climate change. In parts of the Middle East, climate change increased the probability of the event by about a factor of five.
“People suffered and died when April temperatures soared in Asia,” said Friederike Otto, study author and climate scientist at Imperial College in London. “If humans continue to burn fossil fuels, the climate will continue to warm, and vulnerable people will continue to die.”
At least 28 heat-related deaths were reported in Bangladesh, as well as five in India and three in Gaza in April. Surges in heat deaths have also been reported in Thailand and the Philippines this year according to the study.
The heat also had a large impact on agriculture, causing crop damage and reduced yields, as well as on education, with school vacations having to be extended and schools closed in several countries, affecting thousands of students.
Myanmar, Laos and Vietnam broke records for their hottest April day, and the Philippines experienced its hottest night ever with a low of 29.8 degrees Celsius (85.6 degrees Fahrenheit). In India, temperatures reached as high as 46 degrees Celsius (115 degrees Fahrenheit). The month was the hottest April on record globally and the eleventh consecutive month in a row that broke the hottest month record.
Climate experts say extreme heat in South Asia during the pre-monsoon season is becoming more frequent and the study found that extreme temperatures are now about 0.85 degrees Celsius (1.5 Fahrenheit) hotter in the region because of climate change.
Internally displaced people, migrants and those in refugee camps were especially vulnerable to the searing temperatures, the study found.
“These findings in scientific terms are alarming,” said Aditya Valiathan Pillai, a heat plans expert at New Delhi-based think tank Sustainable Futures Collaborative. “But for people on the ground living in precarious conditions, it could be absolutely deadly.” Pillai was not part of the study.
Pillai said more awareness about heat risks, public and private investments to deal with increasing heat and more research on its impacts are all necessary to deal with future heat waves.
“I think heat is now among the foremost risks in terms of personal health for millions across the world as well as nations’ economic development,” he said.


Amsterdam university cancels classes after violence erupted at a pro-Palestinian rally

Amsterdam university cancels classes after violence erupted at a pro-Palestinian rally

  • Israel has killed more than 35,000 Palestinians, according to Gaza’s Health Ministry
  • The protest was one of many that sprung up around Europe following rallies across college campuses in the United States

THE HAGUE: The University of Amsterdam canceled classes Tuesday and shut buildings for two days after the latest pro-Palestinian demonstrations over the war in Gaza turned destructive.
Protests continued to simmer at several European universities where students faced off with academic authorities on whether relations with Israel should be broken off or drastically reduced, as the death toll continues to climb during the seven-month Israel-Hamas war.
Overall, the protests in Europe have failed to reach the intensity of demonstrations at several US universities.
In the Netherlands, the board at the nearly 400-year old University of Amsterdam issued a statement saying it could not guarantee the safety of anyone on campus after a group of masked agitators barricaded doors and spray painted slogans on the walls.
The mayhem on Monday followed a peaceful walkout of staff and students against the Israel-Hamas war and the university’s response to earlier protests.
“They (the university) called in the police after people wouldn’t remove their face coverings but the police came in balaclavas,” political science professor Enzo Rossio told The Associated Press, describing Monday’s events. He had returned to his office following the walkout, only for the building to be evacuated minutes later.
While standing outside the building, Rossio said he and his wife, who also works for the university, were repeatedly hit by police with batons.
Last week, police used a bulldozer to evict demonstrators from an encampment established by students who want the university to cut ties with Israel. The protest was one of many that sprung up around Europe following rallies across college campuses in the United States.
Smaller demonstrations have taken place against the war, both at the University of Amsterdam and at other Dutch universities. But last week’s protest grew into the thousands, with demonstrators chanting slogans including, “Palestine will be free!” and “Cops off campus!”
Riot police were called in multiple times to end the demonstrations, leading to aggressive confrontations. “I’ve never witnessed this kind of violence,” history student Marin Kuijt said in an interview. Kuijt said he had regularly attended climate change marches and joined the walkout on Monday to protest against the university and police response.
After the walkout, some students set up tents inside buildings, intending to occupy the spaces until the university listened to their demands. According to the University of Amsterdam, the peaceful protest was “hijacked by violent elements” who left behind “wanton destruction.”
Higher education institutions in the Netherlands published guidelines on Tuesday for student protests. They include a ban on remaining overnight, occupying buildings and wearing face coverings. Last week, the University of Amsterdam already announced it would not hold talks with any protester who refused to show their face.
In a statement, Amsterdam Student Encampment, which is organizing some of the demonstrations, said it was concerned about outside elections causing destruction, saying it “overshadowed” the protests. The group is calling for more demonstrations at the university in the coming days.
Smaller students actions were held in Belgium, Greece and Italy, among other EU nations.

UK Mideast minister: Israel’s actions leaving its allies ‘pretty challenged’

  • Lord Ahmad: Many are uneasy about adherence to international humanitarian law
  • UK FM opposes arms ban despite ‘grave concerns around humanitarian access issue in Gaza’

LONDON: The UK’s Middle East minister has warned that the war in Gaza is causing Israel’s allies numerous problems over allegations that it has broken international humanitarian law, the Daily Telegraph reported.

“I think Israel is really leaving many of its partners, including ourselves, pretty challenged on where we are currently on the issue of IHL, and how they are fulfilling their obligations,” Lord Ahmad told the House of Commons Foreign Affairs Committee on Tuesday.

“Israel has obligations. We are allies of Israel and as a constructive friend to Israel, we’d land these points very directly to them.”

On Sunday, UK Foreign Secretary David Cameron said an arms ban against Israel would not be “a wise path.”

In April, he said the UK’s stance on selling arms to Israel was “consistent with the advice that I and other ministers have received, and as ever we will keep the position under review.

“Let me be clear, though, we continue to have grave concerns around the humanitarian access issue in Gaza.”

UK law requires a ban on the sale of weapons to states that breach or fall short of adhering to international humanitarian law.

So far Canada, Japan, Spain, Belgium and the Netherlands have suspended arms sales to Israel. The UK’s main opposition Labour Party called for a halt on exports this week.

8 dead, at least 40 injured as farmworkers’ bus overturns in central Florida

  • The bus was transporting 53 farmworkers at about 6:40 a.m. when it collided with a truck
  • The workers were being transported to Cannon Farms in Dunellon

FLORIDA: A bus carrying farmworkers in central Florida overturned on Tuesday, killing eight people and injuring about 40 other passengers, authorities said.
The bus was transporting 53 farmworkers at about 6:40 a.m. when it collided with a truck in Marion County, north of Orlando, the Florida Highway Patrol said.
Authorities say the bus swerved off State Road 40, a straight but somewhat hilly two-lane road that passes through farms. It crashed through a fence and ended up on its side in a field. The workers were being transported to Cannon Farms in Dunellon, which has been harvesting watermelons.
Photos taken by the Ocala Star-Banner at the scene show the bus lying on its side with both its emergency rear door and top hatch open. The truck that hit it shows extensive damage to its driver’s side.
There is no immediate indication that weather was a factor.
“We will be closed today out of respect to the losses and injuries endured early this morning in the accident that took place to the Olvera Trucking Harvesting Corp.,” Cannon Farms announced on its Facebook page. “Please pray with us for the families and the loved ones involved in this tragic accident. We appreciate your understanding at this difficult time.”
Cannon Farms describes itself as a family owned commercial farming operation that has farmed its land for more than 100 years, focusing now on peanuts and watermelons, which it sends to grocery stores across the US and Canada.
No one answered the phone at Olvera Trucking on Tuesday afternoon. The company had recently advertised for a temporary driver to bus workers to watermelon fields. The driver would then operate harvesting equipment. The pay was $14.77 an hour.

Harvard students end protest as university agrees to discuss Middle East conflict

  • The student protest group Harvard Out of Occupied Palestine said in a statement that the encampment “outlasted its utility with respect to our demands”
  • Students at many college campuses this spring set up similar encampments

CAMBRIDGE, Massachusetts: Protesters against the war between Israel and Hamas were voluntarily taking down their tents in Harvard Yard on Tuesday after university officials agreed to discuss their questions about the endowment, bringing a peaceful end to the kinds of demonstrations that were broken up by police on other campuses.
The student protest group Harvard Out of Occupied Palestine said in a statement that the encampment “outlasted its utility with respect to our demands.” Meanwhile, Harvard University interim President Alan Garber agreed to pursue a meeting between protesters and university officials regarding the students’ questions.
Students at many college campuses this spring set up similar encampments, calling for their schools to cut ties with Israel and businesses that support it.
The latest Israel-Hamas war began when Hamas and other militants stormed into southern Israel on Oct. 7, killing around 1,200 people and taking an additional 250 hostage. Palestinian militants still hold about 100 captives, and Israel’s military has killed more than 35,000 people in Gaza, according to Gaza’s Health Ministry, which doesn’t distinguish between civilians and combatants.
Harvard said its president and the dean of the Faculty of Arts and Sciences, Hopi Hoekstra, will meet with the protesters to discuss the conflict in the Middle East.
The protesters said they worked out an agreement to meet with university officials including the Harvard Management Company, which oversees the world’s largest academic endowment, valued at about $50 billion.
The protesters’ statement said the students will set an agenda including discussions on disclosure, divestment, and reinvestment, and the creation of a Center for Palestine Studies. The students also said that Harvard has offered to retract suspensions of more than 20 students and student workers and back down on disciplinary measures faced by 60 more.
“Since its establishment three weeks ago, the encampment has both broadened and deepened Palestine solidarity organizing on campus,” a spokesperson for the protesters said. “It has moved the needle on disclosure and divestment at Harvard.”
