Chandra Detects Giant X-Ray Bubble Around Young Sun-Like Star HD 61005
NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its stellar wind is far stronger than today’s solar wind, forming a 200 astronomical unit-wide astrosphere that offers rare insight into how the young Sun onc...

Cosmic Visitor: 4.56-Billion-Year-Old Meteorite Strikes into Georgia Home
On June 26, 2025, a dazzling daytime fireball streaked over Georgia, captured by satellites and witnessed across multiple states. A surviving fragment smashed through the roof of a McDonough home, denting the wooden floor 14 feet below. Scientists at the University of Georgia analyzed about 23 grams of this ancient rock, determining it to be a 4.56...

Earth to Spin Faster on July 22 to Make It One of the Shortest Days in Recorded History
On Tuesday, July 22, 2025, Earth will complete its rotation 1.34 milliseconds faster than the usual 24 hours, scientists say. That will make it the second-shortest day ever recorded, just behind July 10, 2025. The trend of shorter days has accelerated since 2020, attributed to factors like the Moon’s position, mass shifts from melting ice, and at...

NASA Perseverance Rover Discovers Ancient Rock Sample on Mars' Jezero Crater
NASA’s Perseverance rover has collected a unique rock sample from Mars' Jezero Crater. The rock, named “Silver Mountain,” is believed to be one of the oldest in the solar system, possibly dating back to the Noachian period, over 4 billion years ago. This discovery provides new insights into Mars’ geological history and past environmental co...

Rubin Observatory’s 2025 Debut Could Unveil Hidden Dark Comets in Space
The Vera Rubin Observatory, set to begin operations in 2025, is expected to revolutionise the study of dark comets. These elusive objects, which lack visible tails but exhibit non-gravitational acceleration, have already been identified in our solar system, but their true numbers remain unknown. The observatory's advanced technology, including a po...

New Lunar Map Attempts to Identify the Origin Impact Craters of Rock Samples
A new map of the moon’s Mare Orientale basin highlights areas containing original impact melt. These findings could help date the basin’s formation, which is estimated to be 3.8 billion years old. Scientists believe this research may reveal Earth’s early impact history while guiding future lunar sample-return missions. The map also distinguis...

James Webb Space Telescope Discoveries Challenge Theories About Asteroid Psyche’s Origin
Recent findings from the James Webb Space Telescope (JWST) have introduced new uncertainties about asteroid 16 Psyche. Known for its high iron content, Psyche was previously considered a potential remnant of a protoplanet, providing a valuable opportunity to study the early solar system. However, JWST has detected hydrated minerals on its surface, ...
