James Webb Telescope Detects Potential Gas Giant Exoplanet Just 4 Light-Years Away
Astronomers using JWST have spotted a possible gas giant orbiting Alpha Centauri A, only 4 light-years away. If confirmed, it would be the closest exoplanet to a Sun-like star ever imaged. The discovery could challenge current models of planetary formation in binary systems and open new opportunities for studying nearby worlds.

Doomed Exoplanet TOI-2109b Spirals Toward Its Star with Three Possible Fates
The gas giant TOI-2109b, over five times Jupiter’s mass, is spiraling closer to its star in a rare planetary death spiral. With a 16-hour orbit and blistering heat, the exoplanet could either plunge into its host star, be torn apart by tidal forces, or evolve into a rocky super-Earth through photoevaporation. NASA’s TESS and ESA’s Cheops data...

Giant Trolls Built From Trash Want To Save Humans From Themselves
Nestled in forests around the world, a gentle army of giant wooden trolls want to show humans how to live better without destroying the planet

Young Exoplanet Spotted Shedding Atmosphere Under Stellar Radiation
NASA’s Chandra X-ray Observatory and Hubble Space Telescope have captured a dramatic cosmic event: a baby exoplanet, TOI 1227 b, is being stripped of its atmosphere by powerful X-rays from its host star. Only 8 million years old and orbiting a red dwarf, this Jupiter-sized planet is losing gas at a rate equal to Earth’s entire atmosphere every ...

Uranus Found Emitting Internal Heat, Reviving Hopes for Flagship NASA Mission
Astronomers have discovered that Uranus emits 12% more heat than it receives from sunlight, contradicting past data from Voyager 2. The internal warmth likely comes from leftover energy in the planet’s core, offering clues to its tilt and interior structure. This unexpected heat has intensified calls for a flagship NASA mission to Uranus. Scienti...

Did Something Hit Saturn? Astronomers Investigate Possible Impact Flash
Unlike rocky planets where asteroid impacts leave visible craters, gas giants like Saturn have outer layers of hydrogen and helium that can absorb impacts without obvious traces.

Discovery Of Small Star Giving Birth To Huge Planet Leaves Scientists Puzzled
TOI-6894 is roughly 240 light-years from Earth in the constellation Leo and is the smallest-known star to host a large planet.

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.

Coldest Exoplanet Orbiting A Dead Star Found By Scientists
Scientists said it was the first intact exoplanet to have been found in the forbidden zone of a star.

New Study Reveals How Jupiter’s Storms Hide Ammonia
A new study reveals Jupiter’s monster storms create mushballs—giant hailstones made of ammonia and water. This discovery explains the puzzling absence of ammonia in the planet’s upper atmosphere and suggests similar processes might be happening on gas giants across the universe.

New Study Reveals Chemical Secret Of Earth's 4.5 Years Billion Crust
Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet's magma creates continents - and may have even helped create life.

NASA's Webb Captures First Direct Images Of Carbon Dioxide Outside Solar System
This finding provides compelling evidence that the giant planets in HR 8799 formed through core accretion, a process similar to the formation of Jupiter and Saturn.

Exoplanet WASP-121 b’s Atmosphere Features Iron Rains, Jet Streams, and More
Astronomers have uncovered extreme weather patterns on WASP-121 b, a gas giant 900 light-years from Earth. The planet experiences iron rain, with metals vaporizing on its scorching dayside and condensing into liquid at night. Supersonic winds carry elements across its atmosphere, forming powerful jet streams. Using the Very Large Telescope, researc...
