NASA astronaut Jonny Kim returns after 8 months in space; here’s what he brought back for humanity
NASA astronaut Jonny Kim has returned to Earth after an eight-month mission aboard the International Space Station. He conducted vital research in areas like bioprinting and robotics, contributing to advancements in medicine and future space exploration. The mission highlights the ISS's crucial role in scientific discovery and preparing for deeper space travel.
Longest solar eclipse in 100 years to occur in 2027: When, where to watch rare celestial event, India visibility and viewing tips
Prepare for a rare celestial spectacle as the longest total solar eclipse in a century occurs on August 2, 2027. For an unprecedented 6 minutes and 23 seconds, the Moon will completely obscure the Sun, plunging parts of North Africa, the Middle East, and the Indian Ocean into midday darkness. India will experience a partial eclipse during this extraordinary event.
Saudi Arabia to witness century’s longest Solar Eclipse on August 2, 2027
On August 2, 2027, Saudi Arabia will witness the longest solar eclipse in 100 years, with the Moon blocking the Sun for over six minutes. The eclipse will also pass across North Africa and southern Spain. Daylight will fade to twilight, and the Sun’s glowing corona will shine around the Moon, offering observers a rare, breathtaking celestial spectacle.
3I/ATLAS is carrying ‘key’ ingredients for life, NASA scientist finds
Ever since interstellar visitor 3I/ATLAS entered view in July, its strange behaviour, shifting colours, erratic motion, a puzzling 16.16-hour “heartbeat,” has fuelled both scientific curiosity and speculation. Now, NASA astrochemist Martin Cordiner’s team has detected unusually abundant methanol and hydrogen cyanide in its plume, chemicals linked to life’s origins. Harvard’s Avi Loeb says the new data only deepens the mystery.

Did airport body scanners really see you naked? Here’s what they show today
Early airport body scanners were far more revealing than most travellers realised. In the early 2010s, Rapiscan X-ray machines produced highly detailed, near-nude images that sparked outrage and were ultimately removed over privacy concerns. Experts tell Reader’s Digest that today’s millimetre-wave scanners work very differently, generating only a generic avatar and flagging possible threats without exposing anyone’s actual body.
What NASA says would happen if Earth got too close to a black hole
Approaching a black hole unleashes extreme tidal forces, stretching and tearing apart matter, including planets like Earth, a phenomenon known as spaghettification. Time also slows dramatically due to gravitational time dilation. While a supermassive black hole might offer a slightly less violent initial encounter, survival remains improbable due to radiation and instability.
CH-3 data reveals unexpectedly active electrical environment at Moon’s South Pole
The discovery made by Chandrayaan-3's lander has revealed a vibrant plasma environment in the Moon's southern polar areas. Recent measurements indicate an unexpected surge in electron densities and energetic particles, surpassing earlier predictions. This dynamic, electrically charged layer is greatly influenced by solar wind and Earth’s magnetic forces, providing vital knowledge that could shape upcoming lunar explorations.
Aditya-L1’s data sheds new light on May 2024 superstorm
In an exciting revelation, Indian scientists have teamed up with data from Aditya-L1 and US spacecraft to decode the mysteries surrounding Gannon's storm, the formidable solar storm of May 2024. Their research unveiled the dramatic interplay of two colliding coronal mass ejections that engaged in a significant magnetic reconnection, resulting in intensified solar activity directed at Earth.
NASA reveals how astronauts manage periods in space and why it matters for Moon and Mars missions
Space agencies are now focusing on menstrual care for astronauts. Longer missions to the Moon and Mars require sustainable and waste-efficient solutions. Research is exploring options like menstrual cups to provide astronauts with more autonomy and dignity. This shift ensures all crew members can work effectively and safely in space.
Northern lights to light up sky on December 9: When, where and how to view the rare celestial event
A powerful solar storm is set to bring the Northern Lights to lower latitudes on December 9th. Skywatchers across many US states could witness vibrant auroral displays, extending far beyond their usual northern zones. Experts advise seeking dark, clear skies for the best chance to see this rare celestial event.
Alien signal or atmospheric mystery? NASA reveals truth behind red ‘jellyfish’ lights and sprites over Earth
Mysterious red lights falling from space, initially thought to be alien signals, have been identified by scientists as red sprites. These rare upper-atmosphere lightning phenomena occur high above thunderstorms, appearing as upward-traveling pillars or jellyfish-shaped glows. Captured by citizen scientists and astronauts, these striking electrical events are triggered by powerful ground lightning strikes.
Mars’ largest river systems revealed: Insights into ancient water, sediment deposits, and potential habitability for past life
Ancient Mars once teemed with flowing rivers, forming vast drainage systems. A new study has mapped these large basins, revealing they concentrated nutrients and sediments, making them prime locations for potential past life. These findings are crucial for guiding future missions in the search for evidence of ancient Martian habitability.
