NASA’s Hubble Space Telescope reobserved interstellar comet 3I/ATLAS Nov. 30, with its Wide Field Camera 3 instrument Ever since 3I/ATLAS was first spotted in July, it’s been the space object everyone argues about. It’s only the third interstellar visitor ever found passing through our Solar System, it refused to sit neatly in the “just another…

BENGALURU: More than a year after the most disruptive solar event in more than two decades, Indian scientists have pieced together why the May 2024 storm, now known as Gannon’s storm, struck Earth with such force. A new study in the journal Astrophysical Journal Letters draws on observations from India’s Aditya-L1 satellite and six US…

BENGALURU: Fresh analysis of data from the Chandrayaan-3 lander has revealed that the plasma environment near the Moon’s southern high latitudes is far more active than earlier believed. The results, based on measurements collected between Aug 23, 2023 and Sept 3, 2023, mark the first direct observations of near-surface plasma at such low altitudes in…

Old airport security used Rapiscan backscatter scanners that showed fully detailed body images/ image:X If you’ve ever shuffled through an airport body scanner wondering how much the machine can actually see, you’re not alone. For a while, the answer was: far more than most travellers realised. And that’s exactly why the technology had to change….

Black holes capture the imagination of scientists and space enthusiasts because they represent the most extreme gravitational forces in the universe. NASA explains that anything approaching a black hole encounters enormous tidal forces that stretch and distort matter, and that time itself slows dramatically due to gravitational time dilation. According to NASA, if an object…

Menstruation in space is a topic that has long been overlooked, yet it is becoming an essential part of astronaut health research as more women travel beyond Earth and missions grow longer. Spaceflight changes how the human body functions. Microgravity affects circulation, fluid movement, bone density, muscle strength, and immune response. These physiological shifts can…

Stunning images of mysterious red lights appearing to fall from space have captured global attention, sparking widespread speculation online. Many social media users suggested these ghostly flashes could be linked to alien signals, but scientists and space agencies have confirmed a more down-to-earth explanation. These striking phenomena are known as red sprites, a rare and…

A major new genetic study has resolved one of archaeology’s longest-running debates, confirming that modern humans first reached Australia around 60,000 years ago. The findings align with archaeological discoveries and long-held Aboriginal oral histories that point to a deep human presence on the continent far earlier than some genetic models had previously suggested.Researchers analysed nearly…

The earliest stages of the universe are often envisioned as chaotic, filled with young galaxies that lacked order or recognisable structure. Yet recent high resolution imaging from the James Webb Space Telescope has revealed a galaxy that appears far more mature than expected for its epoch, offering a rare glimpse into the complexity of cosmic…

Mars Express mission has uncovered a remarkable geological formation on Mars that resembles a butterfly. Situated in the Idaeus Fossae region, this unusual crater has intrigued scientists across the globe, providing valuable insights into the planet’s complex geological history. The butterfly shape was formed by a shallow-angle impact, which caused debris to be ejected in…
