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.

Astronomers Capture Two Giant Planets Forming Around Young Star WISPIT 2
Astronomers have directly imaged two giant planets forming around the young star WISPIT 2. The system, just 5.4 million years old, shows rings, gaps, and active planet formation, offering a rare real-time glimpse into how solar systems like ours are born.

Kepler-51 Super-Puff Planets Baffle Scientists as JWST Finds No Atmosphere Clues
The Kepler-51 system hosts three ultra-light “super-puff” planets with massive atmospheres and tiny cores. New JWST observations failed to detect atmospheric signatures, suggesting thick hydrocarbon haze and deepening the mystery of how such worlds form.

Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...

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...

James Webb Watches a Young Star Bake Crystals for Future Planets
Using NASA’s James Webb Space Telescope, astronomers have observed a young star in the Serpens Nebula forging crystalline silicates during powerful outbursts. The findings explain how heat-formed minerals can end up in cold cometary regions and planet-forming disks, shedding light on early stages of planet formation.

Hubble Captures Rare Collision in Nearby Planetary System, Revealing Violent Planet Formation
Astronomers using NASA’s Hubble Space Telescope have witnessed rare collisions between rocky bodies in the Fomalhaut system. The glowing debris clouds created by these impacts offer a unique glimpse into how planets form and highlight challenges in identifying true exoplanets.

Planets Could Create Their Own Water While Forming, Expanding Possibilities for Habitable Worlds
Lab experiments show planets can generate water during formation, not just via comets. This suggests habitable conditions may be widespread in the galaxy, expanding possibilities for life-friendly exoplanets.

Astronomers Stunned As Rogue Planet Grows At Record Speed
The object, known as Cha 1107-7626, lies about 620 light-years away and is estimated to be five to ten times the mass of Jupiter.

Breakthrough Photo: See The 'Birth' Of A Planet For The Very First Time
A team of astronomers has detected for the first time a planet outside our solar system, embedded in a cleared gap of a multi-ringed disc.

Astronomers Capture Planet Birth Around Baby Sun Outside Solar System
Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

Astronomers Discover Baby Planets Taking Their First Steps in Nearby Stellar Nursery
Astronomers have detected early signs of planet formation in 27 young protoplanetary disks within the Ophiuchus star-forming region, just 460 light-years away. High-resolution imaging revealed spiral and ring patterns forming earlier than expected, suggesting stars and planets may grow together from infancy. The findings bridge a knowledge gap betw...

James Webb Telescope Spots Planet Formation in Harshest Known Galactic Environments
The James Webb Space Telescope has revealed that planets can form in extreme radiation zones. A protoplanetary disk called XUE 1, exposed to intense ultraviolet light, still shows signs of water and potential for rocky planet formation. The findings challenge old assumptions and broaden the possible regions where Earth-like planets may emerge.

Astronomers Discover Likely Site Of New Gas Giant Planet In Formation
The astronomers now hope to be able to take an actual image of the young planet using the sensitivity of JWST.

New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery
A new study on PDS 70b, a forming exoplanet located 400 light-years away, reveals a significant mismatch between its atmospheric composition and the surrounding protoplanetary disk. This discovery casts doubt on existing planet formation models, suggesting that more research is needed to understand how planets gather materials and elements during t...
