  New 'Quasi-Moon' Discovered in Earth Orbit May Have Been Hiding There for Decades

  Astronomers have identified asteroid 2025 PN7 as a possible quasi-moon of Earth, trailing our planet for nearly 70 years. At just 62 feet wide, it is the smallest and least stable quasi-satellite detected so far. Researchers believe advanced observatories like the Vera Rubin Observatory could uncover more hidden companions in Earth-like orbits

  Asteroids vs Comets vs Meteors vs Meteorites: What Are They and How Are They Different From Each Other?

  Asteroids, comets, meteoroids, meteors, and meteorites may seem similar, but each plays a unique role in the Solar System. Asteroids are rocky remnants, comets are icy wanderers, meteors are shooting stars, and meteorites are fragments that survive the plunge to Earth.

  NASA Tracks Newly Discovered Bus-Sized Asteroid as It Flies Past Earth

  A newly discovered asteroid, 2025 QV5, about the size of a school bus, will safely pass Earth today at a distance of 500,000 miles, roughly twice as far as the moon. NASA’s JPL notes it will not return this close again until September 2125. Scientists are tracking its path to refine orbital predictions and future flybys.

  NASA’s OSIRIS-REx Mission Finds Stardust in Asteroid Bennu Older Than the Solar System

  NASA’s OSIRIS-REx mission has found presolar stardust grains inside Bennu’s samples. These tiny particles, older than the Sun, carry chemical fingerprints of ancient stars and interstellar space. Bennu thus serves as a pristine time capsule, preserving the earliest clues to the birth of our solar system.

  Massive Fireball Streaks Across Southern Japan, Lighting Up the Night Sky

  On Aug. 19, residents of southern Japan witnessed a brilliant fireball streaking across the night sky, lighting up cities from Kagoshima to Osaka. The meteor appeared at 11:08 p.m. local time, glowing green-blue with flashes so bright they rivaled the moon before bursting into orange-red fragments above the Pacific Ocean. Security and dashcam camer...

  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...

  Shocking Study Shows You're More Likely To Die From An Asteroid Than Rabies

  A new study finds that dying from an asteroid impact is more likely than dying from rabies, though both are rare. The research compares asteroid risk with other unusual causes of death to help guide prevention strategies.

  Gold Defies Physics: Remains Solid at 14x Its Melting Point in Superheating Experiment

  Gold has amazed scientists by remaining solid under extreme temperatures—14 times its standard melting point—due to superheating. The study highlights how conventional physics may not fully explain ultra-fast reactions. These groundbreaking results, published in collaboration with international labs, have far-reaching implications for high-ener...

  Hubble Captures First Images of Ancient Interstellar Visitor Comet 3I/ATLAS

  Hubble has captured images of comet 3I/ATLAS, an ancient interstellar object likely 7 billion years old. As only the third known visitor from beyond the solar system, it offers rare insights into distant planetary systems. With its water ice and D-type asteroid-like dust, 3I/ATLAS is now under global scientific scrutiny before it vanishes back into...

  China’s Tianwen 2 Probe Snaps Striking Views of Earth and Moon While En Route to Asteroid

  China’s Tianwen 2 spacecraft, now millions of kilometers from Earth, captured distant images of Earth and the moon as it journeys to asteroid Kamo'oalewa. Set to collect samples by 2026 and return them in 2027, the mission could reveal insights into the solar system’s formation—before continuing on to a second deep-space target, comet 311P/PA...

  Massive Boulders Ejected by DART Mission Could Complicate Future Asteroid Deflection

  NASA’s DART mission successfully deflected an asteroid but also unleashed high-velocity boulders with unexpected momentum. These chaotic ejecta may alter asteroid spin and orbit, complicating future deflection strategies. A new study highlights the importance of accounting for such forces in planetary defence. ESA’s Hera mission will further in...
