NASA launches revolutionary space telescope to give glimpse of early universe

Published

on

NASA‘s James Webb Space Telescope, built to give the world a glimpse of the universe as it existed when the first galaxies formed, was launched by rocket early Saturday from South America’s northeastern coast, opening a new era of astronomy.

The revolutionary $9 billion infrared telescope, described by NASA as the premiere space-science observatory of the next decade, was carried aloft inside the cargo bay of an Ariane 5 rocket that blasted off at about 7:20 a.m. EST (1220 GMT) from the European Space Agency’s (ESA) launch base in French Guiana.

The flawless Christmas Day launch, with a countdown conducted in French, was carried live on a joint NASA-ESA webcast.

“From a tropical rain forest to the edge of time itself, James Webb begins a voyage back to the birth of the universe,” a NASA commentator said as the two-stage launch vehicle, fitted with double solid-rocket boosters, roared off its launch pad into cloudy skies.

After a 27-minute, hypersonic ride into space, the 14,000-pound instrument was released from the upper stage of the French-built rocket about 865 miles above the Earth, and should gradually unfurl to nearly the size of a tennis court over the next 13 days as it sails onward on its own.

Live video captured by a camera mounted on the rocket’s upper stage showed the Webb gliding gently away after it was jettisoned, drawing cheers and applause from jubilant flight engineers in the mission control center.

Flight controllers confirmed moments later, as the Webb’s solar-energy array was deployed, that its power supply was working.

Coasting through space for two more weeks, the Webb telescope will reach its destination in solar orbit 1 million miles from Earth – about four times farther away than the moon. And Webb’s special orbital path will keep it in constant alignment with the Earth as the planet and telescope circle the sun in tandem.

By comparison, Webb’s 30-year-old predecessor, the Hubble Space Telescope, orbits the Earth from 340 miles away, passing in and out of the planet’s shadow every 90 minutes.

Named after the man who oversaw NASA through most of its formative decade of the 1960s, Webb is about 100 times more sensitive than Hubble and is expected to transform scientists’ understanding of the universe and our place in it.

Webb mainly will view the cosmos in the infrared spectrum, allowing it to gaze through clouds of gas and dust where stars are being born, while Hubble has operated primarily at optical and ultraviolet wavelengths.

The new telescope’s primary mirror – consisting of 18 hexagonal segments of gold-coated beryllium metal – also has a much bigger light-collecting area, enabling it to observe objects at greater distances, thus farther back into time, than Hubble or any other telescope.

That, astronomers say, will bring into view a glimpse of the cosmos never previously seen – dating to just 100 million years after the Big Bang, the theoretical flashpoint that set in motion the expansion of the observable universe an estimated 13.8 billion years ago.

Hubble’s view reached back to roughly 400 million years following the Big Bang, a period just after the very first galaxies – sprawling clusters of stars, gases and other interstellar matter – are believed to have taken shape.

NASA Administrator Bill Nelson, speaking during the launch webcast by video link, hailed the new telescope as a “time machine” that will “take us back to the very beginnings of the universe.”

Aside from examining the formation of the earliest stars and galaxies, astronomers are eager to study super-massive black holes believed to occupy the centers of distant galaxies.

Webb’s instruments also make it ideal to search for evidence of potentially life-supporting atmospheres around scores of newly documented exoplanets – celestial bodies orbiting distant stars – and to observe worlds much closer to home, such as Mars and Saturn’s icy moon Titan.

The telescope is an international collaboration led by NASA in partnership with the European and Canadian space agencies. Northrop Grumman Corp was the primary contractor. The Arianespace launch vehicle is part of the European contribution.

Webb was developed at a cost of $8.8 billion, with operational expenses projected to bring its total price tag to about $9.66 billion, far higher than planned when NASA was previously aiming for a 2011 launch.

Astronomical operation of the telescope, to be managed from the Space Telescope Science Institute in Baltimore, is expected to begin in the summer of 2022, following about six months of alignment and calibration of Webb’s mirrors and instruments.

It is then that NASA expects to release the initial batch of images captured by Webb. Webb is designed to last up to 10 years.

Australia social media ban set to take effect, sparking a global crackdown

For the social media businesses, the implementation marks a new era of structural stagnation as user numbers flatline and time spent on platforms shrinks, studies show.

Australia is set to become the first country to implement a minimum age for social media use on Wednesday, with platforms like Instagram, TikTok and YouTube forced to block more than a million accounts, marking the beginning of an expected global wave of regulation.

From midnight, 10 of the biggest platforms will be required to block Australians aged under 16 or be fined up to A$49.5 million ($33 million), Reuters reported.

The law received harsh criticism from major technology companies and free speech advocates, but was praised by parents and child advocates.

The rollout closes out a year of speculation about whether a country can block children from using technology that is built into modern life. And it begins a live experiment that will be studied globally by lawmakers who want to intervene directly because they are frustrated by what they say is a tech industry that has been too slow to implement effective harm-minimisation efforts.

Governments from Denmark to Malaysia – and even some states in the U.S., where platforms are rolling back trust and safety features – say they plan similar steps, four years after a leak of internal Meta (META.O) documents showed the company knew its products contributed to body image problems and suicidal thoughts among teenagers while publicly denying the link existed.

“While Australia is the first to adopt such restrictions, it is unlikely to be the last,” said Tama Leaver, a professor of internet studies at Curtin University.

“Governments around the world are watching how the power of Big Tech was successfully taken on. The social media ban in Australia … is very much the canary in the coal mine.”

A spokesperson for the British government, which in July began forcing websites hosting pornographic content to block under-18 users, said it was “closely monitoring Australia’s approach to age restrictions.”

“When it comes to children’s safety, nothing is off the table,” they added.

Few will scrutinise the impact as closely as the Australians. The eSafety Commissioner, an Australian regulator tasked with enforcing the ban, hired Stanford University and 11 academics to analyse data on thousands of young Australians covered by the ban for at least two years.

Though the ban covers 10 platforms initially, including Alphabet’s (GOOGL.O), YouTube, Meta’s Instagram and TikTok, the government has said the list will change as new products appear and young users switch to alternatives.

Of the initial 10, all but Elon Musk’s X have said they will comply using age inference – guessing a person’s age from their online activity – or age estimation, which is usually based on a selfie. They might also check with uploaded identification documents or linked bank account details.

Musk has said the ban “seems like a backdoor way to control access to the internet by all Australians” and most platforms have complained that it violates people’s right to free speech.

For the social media businesses, the implementation marks a new era of structural stagnation as user numbers flatline and time spent on platforms shrinks, studies show.

Platforms say they don’t make much money showing advertisements to under-16s, but they add that the ban interrupts a pipeline of future users. Just before the ban took effect, 86% of Australians aged 8 to 15 used social media, the government said.

“The days of social media being seen as a platform for unbridled self-expression, I think, are coming to an end,” said Terry Flew, the co-director of University of Sydney’s Centre for AI, Trust and Governance.

Platforms responded to negative headlines and regulatory threats with measures like a minimum age of 13 and extra privacy features for teenagers, but “if that had been the structure of social media in the boom period, I don’t think we’d be having this debate,” he added.

Ethiopian volcano erupts for first time in nearly 12,000 years

Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan.

Published

The Hayli Gubbi volcano in Ethiopia’s Afar region has erupted for the first time in almost 12,000 years, sending massive ash plumes soaring up to 14 kilometres into the atmosphere, according to the Toulouse Volcanic Ash Advisory Centre.

The eruption began on Sunday and lasted several hours. Hayli Gubbi, located around 800 kilometres northeast of Addis Ababa near the Eritrean border, sits within the geologically active Rift Valley, where two major tectonic plates meet. The volcano rises roughly 500 metres above the surrounding landscape.

Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan. Satellite imagery and social-media videos captured a towering column of white smoke billowing into the sky.

The Smithsonian Institution’s Global Volcanism Program notes that Hayli Gubbi has no recorded eruptions during the Holocene, the period dating back about 12,000 years to the end of the last Ice Age.

Volcanologist Simon Carn of Michigan Technological University also confirmed on Bluesky that the volcano had “no record of Holocene eruptions.”

Cloudflare outage easing after millions of internet users affected

Published

on

A global outage at web-infrastructure firm Cloudflare began to ease on Tuesday afternoon after preventing people from accessing major internet platforms, including X and ChatGPT.

Cloudflare, whose network handles around a fifth of web traffic, said it started to investigate the internal service degradation around 6:40 a.m. ET. It has deployed a fix but some customers might still be impacted as it recovers service.

The incident marked the latest hit to major online services. An outage of Amazon’s cloud service last month caused global turmoil as thousands of popular websites and apps, including Snapchat, were inaccessible due to the disruption.

Cloudflare – whose shares were down about 5% in premarket trading – runs one of the world’s largest networks that helps websites and apps load faster and stay online by protecting them from traffic surges and cyberattacks.

The latest outage prevented users from accessing platforms such as Canva, X, and ChatGPT, prompting users to log outage reports with Downdetector.

Downdetector tracks outages by collating status reports from a number of sources. “We saw a spike in unusual traffic to one of Cloudflare’s services beginning at 11:20 UTC. That caused some traffic passing through Cloudflare’s network to experience errors,” the company said in an emailed statement.

“We are all hands on deck to make sure all traffic is served without errors.”
