Ground telescopes have offered our best asteroid data so far, but spotting dark, tumbling rocks from Earth is like finding ink blots in the night sky. That changes with infrared: sun-warmed asteroids glow like red Christmas lights, and the NEO Surveyor is designed to detect them.
The study comes just when NASA’s Curiosity rover detected the largest organic compounds ever found on Mars. But while that breakthrough fuels hopes of uncovering signs of ancient life; the new problem shifts the focus to a more immediate concern — keeping astronauts safe.
From small towns in India to the vast expanse of space, there Indian-origin astronauts have orbited the Earth, conducted spacewalks, and returned with stories that continue to inspire generations.
The discovery of Dark Energy in 1998 was a shock. Before then, scientists believed the Universe’s expansion, triggered by the Big Bang, would gradually slow due to gravity. Instead, astronomers found that expansion was accelerating.
“We have been able to predict the presence of fish schools using ocean satellites, but this information is mostly disseminated through government channels. Has it made an economic impact? Not really," said former ISRO chief.
According to NASA, the asteroid will make its closest approach on March 26, 2025, at 5:04 PM IST, coming within 5 million kilometers of Earth—more than 13 times the Earth-Moon distance.
Tropical cyclones, floods, droughts, and other hazards in 2024 led to the highest number of new displacements recorded for the past 16 years, contributed to worsening food crises, causing massive economic losses
The return of Sunita Williams and Crew-9 after nine months in space was met with cheers in NASA’s control room and lakhs tuning in to the YouTube livestream
The two NASA astronauts splashed down off Florida’s coast on Tuesday at 5:57 p.m. ET (Wednesday, 3:27 a.m. India time) as part of the Crew-9 rotation mission
The Crew Dragon capsule carrying the two astronauts undocked from the ISS and is expected to splash down off the coast of Florida at 3:27 am IST on March 19
The Chandrayaan series has been crucial to India’s lunar exploration efforts. The first mission, Chandrayaan-1 (2008), conducted chemical, mineralogical, and photo-geologic mapping of the Moon.
Williams and Wilmore launched on June 5, 2024, aboard Boeing’s Starliner for its first crewed test flight. However, technical issues their spacecraft turned out to be unsafe for their return journey
Beyond aging, space travel triggers other biological changes. NASA’s famous twins study compared astronaut Scott Kelly, who spent a year in space, to his identical twin, Mark Kelly, who remained on Earth.
The two astronauts have been stuck on the ISS since June 2024, when Starliner—on its maiden crewed voyage—suffered propulsion issues that rendered it unfit for their return journey.
A supernova — the explosive death of a massive star — can leave behind a black hole or neutron star. These cosmic blasts are element factories, spreading carbon, calcium, and iron across space, fuelling new generations of stars and planets.
Solar-driven temperature shifts alter rock properties and underground water movement, potentially making the Earth’s crust more prone to fractures. In regions where tectonic stress is already high, these fluctuations could provide the final push needed to trigger an earthquake.
Astronauts receive comprehensive health coverage for themselves and their families, including specialized screenings, fitness programs, and psychological support to help them adjust before, during, and after missions.
The Crew-10 team includes NASA astronauts Anne McClain and Nichole Ayers, Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA), and Roscosmos cosmonaut Kirill Peskov.
The incoming quartet features NASA astronauts Anne McClain (commander) and Nichole Ayers (pilot), alongside JAXA’s Takuya Onishi and Roscosmos’ Kirill Peskov, both mission specialists.
