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.

Meta turns off Instagram’s private messaging encryption worldwide

Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.

Published

on

Instagram has disabled its end-to-end encrypted (E2EE) direct messaging feature worldwide, marking a major reversal by parent company Meta on its previous commitment to stronger user privacy protections.

The move means Instagram users can no longer send ultra-private direct messages protected by E2EE — a security system that allows only the sender and recipient to read messages. Without the feature, Instagram can technically access the content of direct messages, including photos, videos and voice notes.

Meta had previously promoted encryption as “the future is private.” In 2019, CEO Mark Zuckerberg pledged to expand the technology across the company’s platforms.

Facebook Messenger adopted E2EE in 2023, while Instagram introduced it as an optional feature with plans to make it standard.

However, Meta has now abandoned the wider Instagram rollout and updated the app’s terms in March to confirm encrypted messaging would no longer be supported after 8 May 2026.

Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.

The move has divided opinion. Child protection groups, including the NSPCC, welcomed the change, saying encryption can make it harder to detect child grooming and abuse online.

Privacy advocates criticised the decision. Maya Thomas of Big Brother Watch warned the move weakens online privacy protections and could increase pressure on other social media companies to scale back encryption.

End-to-end encryption remains standard on platforms including WhatsApp, Signal, Apple’s iMessage and Google Messages, while other platforms continue to take mixed approaches to private messaging.

James Webb Telescope captures clearest-ever view of exoplanet’s surface

Published

on

Astronomers using NASA’s James Webb Space Telescope have obtained the clearest view yet of the surface of a rocky exoplanet, revealing a scorched, atmosphere-free world that scientists say resembles a giant version of Mercury.

The planet, known as LHS 3844 b and nicknamed “Kua’kua,” appears to be a barren, uninhabitable world with extreme temperature swings and no detectable atmosphere, according to a study published this week in Nature Astronomy.

Researchers said the planet’s surface is likely covered in dark volcanic rock and ancient regolith — loose rocky debris formed over billions of years from relentless bombardment by radiation and micrometeorite impacts.

“This planet is not a nice place,” said astronomer Laura Kreidberg, senior author of the study. “It’s a hellish, barren rock — much more similar to Mercury than Earth.”

Located about 49 light-years away, LHS 3844 b orbits a small red dwarf star and completes a full orbit every 11 hours. The planet is tidally locked, meaning one side permanently faces its star while the other remains in darkness — similar to how the Moon always shows the same face to Earth.

Scientists found the planet’s dayside reaches roughly 1,340 degrees Fahrenheit (725 degrees Celsius), while the nightside showed almost no detectable heat.

Using Webb’s infrared instruments, researchers were able to directly analyze light coming from the planet’s surface — a major breakthrough for exoplanet science.

“Different rocks have different spectral fingerprints,” said lead author Sebastian Zieba. “Dark volcanic rocks like basalt matched our observations much better than brighter rocks like granite.”

The findings mark a new phase in exoplanet research, shifting beyond atmospheric studies toward direct analysis of alien geology and surface composition.

Since becoming operational in 2022, the Webb telescope has transformed scientists’ understanding of planets beyond the solar system, helping identify atmospheric chemistry, weather patterns and now even the nature of distant planetary surfaces.

Researchers said the absence of an atmosphere on LHS 3844 b means there is little protection from stellar radiation and virtually no possibility of liquid water — a key ingredient for life.

“So overall, this is almost certainly not a habitable world,” Zieba said.

Afghanistan has launched its first-ever 5G telecommunications trial in Kabul, marking a major milestone in efforts to modernise the country’s digital infrastructure.

The announcement followed a meeting between Hamdullah Nomani, Minister of Communications and Information Technology, and Aliullah Sarwari, head of the Afghan Wireless Communication Company (AWCC), where discussions focused on expanding telecom coverage, improving service quality, and extending connectivity to remote regions.

According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis. Once technical preparations and testing are completed, the company plans to extend 5G services to other provinces.

Officials also reported steady progress on broader infrastructure development. Eight telecom sites approved during previous official visits to northern and southeastern provinces have been completed, one is nearing completion, and construction continues on two additional sites expected to become operational soon.

In parallel, the Afghanistan Telecom Regulatory Authority (ATRA) has approved eight more telecom sites under the Telecom Development Fund (TDF), with implementation scheduled in the coming months.

Sarwari noted that since the beginning of 2026, AWCC has built and activated 46 telecom sites using its development budget, while work continues on a further 186 sites nationwide.

He also thanked the Ministry of Communications and Information Technology for its ongoing support in facilitating sector growth and improving service delivery.

Nomani meanwhile emphasised that telecommunications play a crucial role in national development and said the government remains committed to working closely with operators to expand modern, high-quality digital services.

Officials added that cooperation between the ministry, regulators, and telecom companies will continue across all operational and regulatory areas to strengthen Afghanistan’s communications network.
