Antarctica’s coastal glaciers are shedding icebergs more rapidly than nature can replenish the crumbling ice, doubling previous estimates of losses from the world’s largest ice sheet over the past 25 years, a satellite analysis showed on Wednesday. The first-of-its-kind study, led by researchers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles and published in

The US Federal Communications Commission rejected SpaceX’s Starlink and LTD Broadband’s applications for more than $2 billion (roughly Rs. 15,930 crore) in Internet service subsidies, the FCC said on Wednesday. In December 2020, the FCC tentatively awarded $9.2 billion (roughly Rs. 73,281 crore) to over 300 bidders to deploy high-speed broadband from the Rural Digital

The continents of Earth were formed by gigantic meteorite impacts that were particularly prevalent during the first billion years of our planet’s four and a half billion year history, according to new Curtin research, which has presented the strongest proof to yet. Dr Tim Johnson, from Curtin’s School of Earth and Planetary Sciences, said the

SpaceX’s highly anticipated Crew-9 astronaut mission has been delayed to September 24, 2024, due to ongoing technical issues with Boeing’s Starliner spacecraft. Originally scheduled to lift off on August 18, the Crew-9 launch has been pushed back to allow NASA more time to resolve challenges related to the Boeing Crew Flight Test (CFT) currently docked

A new study has revealed that the Milky Way’s thin disk may be much older than previously believed, thanks to the discovery of ancient stars located surprisingly close to our Sun. Researchers using data from the European Space Agency’s Gaia space telescope have found that some of these stars formed less than a billion years

A team of researchers at the Massachusetts Institute of Technology, inspired by fireflies, created insect-sized robots that emit light when they fly. Fireflies are known for their luminescence which they use for communication purposes. The MIT researchers who created these tiny robots intended something similar. The ability of these tiny robots to emit light can

NASA officials said on Wednesday the two astronauts delivered to the International Space Station in June by Boeing’s Starliner could return on SpaceX’s Crew Dragon in February 2025 if Starliner is still deemed unsafe to return to Earth. The US space agency has been discussing potential plans with SpaceX to leave two seats empty on

A newly commissioned supercomputer in Australia has processed a series of radio telescope observations, including a highly detailed image of a supernova remnant. Called Setonix, the newly commissioned supercomputer at the Pawsey Supercomputing Research Centre has created a highly detailed image using data collected by ASKAP (Australian Square Kilometre Array) radio telescope. Operated by the

NASA said on Tuesday it pushed a routine SpaceX launch of astronauts to the International Space Station (ISS) back a month to spend more time analysing issues with Boeing’s Starliner spacecraft, which remains docked at the station. SpaceX’s Crew Dragon spacecraft was initially scheduled to launch four astronauts to the ISS on August 18, but

A team of astronomers at the University of Surrey recently found an extremely faint, dwarf galaxy which, they believe, is one of the first galaxies packed with a very old star. The galaxy, monikered as Pegasus V, is located in the vicinity of the Andromeda galaxy. The observation first came to light after a sky

NASA’s SunRISE — or Sun Radio Interferometer Space Experiment — is an ambitious program that plans to launch the largest radio telescope ever to detect and track hazardous explosive space weather events. The production of the first six satellites has been completed at the Utah State University Space Dynamics Laboratory (SDL), according to the US space agency. The SDL has

The Earth is approximately 1.1 degree Celsius warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly four times faster than the rest

An artificial analog synapse that can run 1 million times faster than the biological ones in the human brain has been developed by a team of researchers at the Massachusetts Institute of Technology (MIT). The newly developed programmable resistors can be used to make up analog neural networks in artificial intelligence systems and can process

A supergiant dying star, which lost a substantial chunk of its visible surface in 2019, is healing up, according to astronomers. Named Betelgeuse, this aging star, with time, has swelled up and now measures approximately 1 billion miles in diameter. Like every dying star, the ultimate fate of Betelgeuse is that it will explode into a supernova. Evidence

In a new project by the California Institute of Technology (Caltech), the scientists aim at peering into the most elusive galaxies in the universe. This is likely to help astronomers paint a clearer and more comprehensive picture of the universe’s history of star formation. The stars began to form some 400 million years ago in

A multinational research team led by UCL has developed an artificial intelligence (AI) programme that can identify minute brain anomalies that lead to epileptic seizures. The algorithm used in the Multicentre Epilepsy Lesion Detection project (MELD), reports the locations of abnormalities in cases of drug-resistant focal cortical dysplasia (FCD), a major cause of epilepsy, was
