Astronomers Discover "Inside-Out" Planetary System With Rocky World Beyond Gas Planets, Challenging Formation Theories
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

NASA’s Hubble Captures Rare Pre-Planetary Transformation as Twin Beams of Light Pierce the Cosmic Dust
A new Hubble image reveals twin beams blasting from a hidden dying star inside the Egg Nebula, a rare pre-planetary phase. The symmetrical arcs and glowing lobes show how Sun-like stars shed dust and gas before forming planetary nebulae, offering scientists a rare glimpse into stellar evolution.

NASA Juno Mission Uncovers Subtle Geometric Shifts That Challenge Existing Models of the Jovian Interior
Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insigh...

Scientists Uncover "Rocket Storms" Speeding Up Water Loss on Mars
This finding suggests that Mars has been losing water year-round for billions of years, rather than just during specific seasons.

SPHEREx Captures Dramatic Outburst of Interstellar Comet 3I/ATLAS
NASA’s SPHEREx telescope captured a dramatic outburst from interstellar comet 3I/ATLAS after its close solar flyby in October 2025. Infrared observations in December revealed water vapor, carbon dioxide, methanol, methane, and cyanide erupting from the comet’s nucleus. Scientists say the chemical makeup suggests formation in a relatively warm e...

Venus May Hide a Vast Underground Tunnel Formed by Ancient Volcanic Eruptions, Scientists Say
Scientists analysing NASA’s Magellan radar data have identified signs of a vast underground lava tunnel on Venus. If confirmed, it would be only the second such structure found on the planet, challenging the belief that Venus is geologically inactive and opening new possibilities for studying its volcanic past.

NASA’s SPHEREx Spots Interstellar Comet Flaring With Gas and Organic Molecules
NASA’s SPHEREx telescope has observed interstellar comet 3I/ATLAS unexpectedly brightening as it leaves the solar system. The comet released water vapour, carbon dioxide, and organic compounds months after its closest solar approach. Scientists say the findings provide a rare chemical snapshot of material formed around another star, helping compa...

NASA Finds a Crucial Life-Building Chemical on Jupiter’s Moon
Scientists studying archival Galileo spacecraft data have identified ammonia-bearing compounds on Europa for the first time. The ammonia appears along surface cracks, indicating recent transport from the moon’s subsurface ocean. Because ammonia contains nitrogen and degrades quickly under radiation, its presence strengthens Europa’s status as a...

NASA’s TESS Captures First Images of Rare Interstellar Comet 3I/ATLAS
NASA’s Transiting Exoplanet Survey Satellite has captured rare images of interstellar comet 3I/ATLAS, only the third such object ever detected. Observations from January 2026 reveal the comet rotates every 15 hours and produces sunlight-driven jets, behaving much like Solar System comets. Scientists say studying 3I/ATLAS may unlock clues about th...

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...
