Rare Meteorite Found In Sahara Proves A Mars-Sized Lost Planet Once Orbited Our Sun
Scientists studying a rare, ancient angrite meteorite found in the Sahara Desert have uncovered evidence of a lost protoplanet from the early Solar System.

Sahara Meteorite May Be Fragment of a Lost Moon-Sized World, Study Suggests
A rare angrite meteorite discovered in the Sahara may have come from a moon-sized protoplanet that existed 4.5 billion years ago. Its unusual minerals point to a large world that later disappeared in a catastrophic collision.

New Study Suggests Uranus and Neptune May Contain More Rock Than Ice
New models suggest Uranus and Neptune may contain significantly more rock than ice beneath their atmospheres. The findings challenge decades of planetary science and could lead to a reclassification of the outer planets.

New Study Finds Earth And Mars May Have Formed From Similar Material
Earth's Composition Closely Matches Mars, Suggests New Study On Planet's Origins

Astronomers Discover Trans-Neptunian Object With Atmosphere in Outer Solar System
Astronomers discovered a faint atmosphere around (612533) 2002 XV93 using a stellar occultation. The finding challenges current theories, as such small, cold bodies should not retain gas, hinting at recent activity like impacts or ice volcanism.

A Visitor from Another Star: Interstellar Comet Reveals Alien Origins
Observations of 3I/ATLAS reveal high levels of heavy water, suggesting it formed in an extremely cold star system. The discovery offers new insights into how planets form beyond our solar system.

NASA Observes Rare Sungrazer Comet Disintegration Near the Sun
NASA spacecraft observed C/2026 A1 (MAPS) disintegrate near the Sun. The sungrazer’s destruction provides valuable insights into comet structure, solar forces, and the early solar system.

Rare Interstellar Comet To Shine In Skies After 170,000 Years: Here's How To Watch
The comet is currently in the constellation Pegasus and passing near the Great Square of Pegasus.

Why Jupiter Has Four Giant Moons While Saturn Has Just One, Study Explains
Scientists suggest the strong magnetic field of Jupiter created regions for multiple large moons to form, unlike Saturn. The findings could reshape how astronomers search for exomoons in distant planetary systems.

Rubin Observatory Discovers Over 11,000 Asteroids Within Weeks of Imaging
The Vera Rubin Observatory has discovered over 11,000 new asteroids within weeks of early observations. The findings highlight its ability to rapidly map the solar system and improve tracking of near-Earth objects for planetary defence.

Hubble Telescope Captures Comet Reversing Its Rotation for the First Time
Using the Hubble Space Telescope, astronomers observed Comet 41P slow, stop, and reverse its spin due to gas jets. The rare phenomenon could mark the beginning of the comet’s breakup as it nears the end of its life.

Saturn And Jupiter Gain New Moons, Take Solar System Satellite Count To 442
The newly discovered moons are "irregular" satellites, meaning they are small (averaging about 3 km across) and have distant, often eccentric orbits.

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...

New ALMA Images Reveal Complex Rings Left Behind by Planet Formation
Astronomers used ALMA to capture unprecedented images of young exoplanetary systems. The ARKS survey mapped 24 debris disks, revealing rings, gaps and collisions that trace planetary evolution. These snapshots expose chaotic transitional stages, helping scientists understand how newborn planets mature into stable systems like our own Solar System t...

Rubin Observatory Discovers Fastest-Spinning Large Asteroid Ever Seen
Astronomers using the Vera C. Rubin Observatory have discovered asteroid 2025 MN45, the fastest-spinning large asteroid ever recorded. About 710 metres wide, the object completes one full rotation every 1.88 minutes—far quicker than any asteroid of similar size. The finding emerged from an early survey that detected nearly 2,000 new asteroids, in...
