Webb telescope: NASA to reveal deepest image ever taken of Universe

  • The James Webb Space Telescope will explore objects in the solar system and atmospheres of exoplanets orbiting other stars

WASHINGTON: NASA administrator Bill Nelson said Wednesday the agency will reveal the “deepest image of our Universe that has ever been taken” on July 12, thanks to the newly operational James Webb Space Telescope.
“If you think about that, this is farther than humanity has ever looked before,” Nelson said during a press briefing at the Space Telescope Science Institute in Baltimore, the operations center for the $10 billion observatory that was launched in December last year and is now orbiting the Sun a million miles (1.5 million kilometers) away from Earth.
A wonder of engineering, Webb is able to gaze further into the cosmos than any telescope before it, thanks to its enormous primary mirror and its instruments that focus on infrared, allowing it to peer through dust and gas.
“It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own,” added Nelson, speaking via phone while isolating with Covid.
“It may answer some questions that we have: Where do we come from? What more is out there? Who are we? And of course, it’s going to answer some questions that we don’t even know what the questions are.”
Webb’s infrared capabilities allow it to see deeper back in time to the Big Bang, which happened 13.8 billion years ago.
Because the Universe is expanding, light from the earliest stars shifts from the ultraviolet and visible wavelengths it was emitted in, to longer infrared wavelengths — which Webb is equipped to detect at an unprecedented resolution.
At present, the earliest cosmological observations date to within 330 million years of the Big Bang, but with Webb’s capacities, astronomers believe they will easily break the record.

In more good news, NASA deputy administrator Pam Melroy revealed that, thanks to an efficient launch by NASA’s partner Arianespace, the telescope could stay operational for 20 years, double the lifespan that was originally envisaged.
“Not only will those 20 years allow us to go deeper into history, and time, but we will go deeper into science because we have the opportunity to learn and grow and make new observations,” she said.
NASA also intends to share Webb’s first spectroscopy of a faraway planet, known as an exoplanet, on July 12, said NASA’s top scientist Thomas Zurbuchen.
Spectroscopy is a tool to analyze the chemical and molecular composition of distant objects and a planetary spectrum can help characterize its atmosphere and other properties such as whether it has water and what its ground is like.
“Right from the beginning, we’ll look at these worlds out there that keep us awake at night as we look into the starry sky and wonder as we’re looking out there, is there life elsewhere?” said Zurbuchen.
Nestor Espinoza, as STSI astronomer, told AFP that previous exoplanet spectroscopies carried out using existing instruments were very limited compared to what Webb could do.
“It’s like being in a room that is very dark and you only have a little pinhole you can look through,” he said, of current technology. Now, with Webb, “You’ve opened a huge window, you can see all the little details.”

China says top military official Miao Hua suspended, under investigation

  • Latest senior apparatchik to fall in a sweeping crackdown on graft in the country’s armed force
  • Unconfirmed reports say defense minister Dong Jun was also placed under investigation for corruption
BEIJING: China said Thursday that top military official Miao Hua had been removed from office and was suspected of “serious violations of discipline,” the latest senior apparatchik to fall in a sweeping crackdown on graft in the country’s armed forces.
The ruling Chinese Communist Party “has decided to suspend Miao Hua from duty pending investigation,” Wu Qian, spokesman of China’s Ministry of Defense, told a press briefing.
Wu did not provide further details about the charges against Admiral Miao, a member of Beijing’s powerful Central Military Commission.
But “serious violations of discipline” are commonly used by officials in China as a euphemism for corruption.
The announcement follows reports, unconfirmed by Beijing, that Defense Minister Dong Jun has been placed under investigation for corruption.
If confirmed, Dong would be the third Chinese defense minister in a row to be probed for graft.

India’s parliament suspended temporarily after row over allegations against Adani group

India’s parliament suspended temporarily after row over allegations against Adani group

  • The problem is that India’s states are unprepared for the rapid rise in renewable generating capacity, lack adequate transmission infrastructure and storage

NEW DELHI: Both houses of Indian parliament were suspended temporarily on Thursday within minutes of opening as opposition lawmakers disrupted proceedings for the third day this week seeking a discussion on allegations against the Adani Group.

US authorities have accused Gautam Adani, his nephew Sagar Adani and managing director of Adani Green, Vneet S. Jaain, of being part of a scheme to pay bribes of $265 million to secure Indian solar power supply contracts, and misleading US investors during fund raises there.

“We want a discussion on this in parliament. It is going to be the third day that we are demanding a reply from the prime minister” on the Adani issue, Manickam Tagore, a lawmaker from the main opposition Congress party, which has been leading the protests against the business group, told news agency ANI.

Many of India’s opposition parties accuse Prime Minister Narendra Modi and his Bharatiya Janata Party (BJP) of favoring Adani and blocking investigations against him in India, accusations both have denied.

Congress leader Rahul Gandhi, who has been a vocal critic of Adani, said Gautam Adani, 62, should be arrested.

While the government has not made any comment on the indictment, Modi’s BJP has said it had no reason to defend Adani, adding that the party was not against industrialists and considered them partners in nation-building efforts.

“Let him defend himself,” BJP spokesperson Gopal Krishna Agarwal said on Tuesday, adding that the law would take its course.

Landslides in Indonesia’s Sumatra kill at least 27, rescuers search for missing

  • Torrential rain in the province since last week had caused flash floods and landslides in four different districts
  • Extreme weather is expected in Indonesia toward the end of 2024, as the La Nina phenomenon increases rainfalls across the tropical archipelago

JAKARTA: Indonesian rescuers are searching for passengers trapped in a minibus buried in mud after flash floods and landslides hit several locations in North Sumatra province, killing at least 27, an official said on Thursday.
Torrential rain in the province since last week had caused flash floods and landslides in four different districts, Indonesia’s disaster agency has said.
A landslide in a village in Deli Serdang on Wednesday killed seven and injured 20, Hadi Wahyudi, North Sumatra police spokesperson told Reuters.
Rescuers were looking for missing people, including those trapped in a minibus and other vehicles on a hilly interprovince road hit by a mudslide, he said, adding he could not give an estimate for the number of affected people.
In other places, rescuers have found 20 dead during a search that started over the weekend. They are still searching for two missing.
“Today, we’re focusing our search to find missing people and clearing the roads affected by the landslides,” said Hadi, adding excavators were deployed.
The landslides and flash floods damaged houses, mosques, and rice fields.
Heavy rains also triggered floods in the provincial capital of Medan, forcing a delay in votes for a regional election in some polling stations.
Extreme weather is expected in Indonesia toward the end of 2024, as the La Nina phenomenon increases rainfalls across the tropical archipelago, the country’s weather agency has warned.


The Australian Senate debates the world’s first social media ban for children under 16

The Australian Senate debates the world’s first social media ban for children under 16

  • The bill that would make social media platforms liable for fines of up to $33 million for systemic failures to prevent young children from holding accounts

MELBOURNE: The Australian Senate was debating a ban on children younger than 16 years old from social media Thursday after the House of Representatives overwhelmingly supported the age restriction.
The bill that would make platforms including TikTok, Facebook, Snapchat, Reddit, X and Instagram liable for fines of up to 50 million Australian dollars ($33 million) for systemic failures to prevent young children from holding accounts.
It is likely to be passed by the Senate on Thursday, the Parliament’s final session for the year and potentially the last before elections, which are due within months.
The major parties’ support for the ban all but guarantees the legislation will become law. But many child welfare and mental health advocates are concerned about unintended consequences.
Unaligned Sen. Jacqui Lambie complained about the limited amount of time the government gave the Senate to debate the age restriction, which she described as “undercooked.”
“I thought this was a good idea. A lot of people out there thought it was a good idea until we looked at the detail and, let’s be honest, there’s no detail,” Lambie told the Senate.
Opposition Sen. Maria Kovacic said the bill was not radical but necessary.
“The core focus of this legislation is simple: It demands that social media companies take reasonable steps to identify and remove underage users from their platforms,” Kovacic told the Senate.
“This is a responsibility these companies should have been fulfilling long ago, but for too long they have shirked these responsibilities in favor of profit,” she added.
Sen. David Shoebridge, from the minor Greens party, said mental health experts agreed that the ban could dangerously isolate many children who used social media to find support.
“This policy will hurt vulnerable young people the most, especially in regional communities and especially the LGBTQI community, by cutting them off,” Shoebridge told the Senate.
The House of Representatives on Wednesday overwhelmingly carried the bill 102 votes to 13.
Communications Minister Michelle Rowland urged senators to pass the bill which she said reflected the Australian community’s view.
“The ... government is on the side of supporting parents and protecting young people,” Rowland told the House.
Once the legislation becomes law, the platforms would have one year to work out how they could implement the ban before penalties are enforced.
The platforms complained that the law would be unworkable, and urged the Senate to delay the vote until at least June next year when a government-commissioned evaluation of age assurance technologies made its report on how young children could be excluded.
Critics argue the government is attempting to convince parents it is protecting their children ahead of general elections due by May. The government hopes that voters will reward it for responding to parents’ concerns about their children’s addiction to social media. Some argue the legislation could cause more harm than it prevents.
Criticisms include that the legislation was rushed through Parliament without adequate scrutiny, is ineffective, poses privacy risks for all users, and undermines parental authority to make decisions for their children.
Opponents of the bill also argue the ban would isolate children, deprive them of the positive aspects of social media, drive them to the dark web, discourage children too young for social media to report harm and reduce incentives for platforms to improve online safety.
