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...

Astronomers Measure Mass and Distance of a Rogue Planet for the First Time in History
Astronomers have measured the mass and distance of a rogue planet for the first time. Using observations from Earth and the Gaia space telescope, the planet was found to be just under Saturn’s mass and about 10,000 light-years away. The study highlights how free-floating planets are ejected from star systems and improves understanding of planetar...

James Webb Space Telescope Spots an Exoplanet Losing Its Atmosphere in a Huge Helium Stream
Astronomers using NASA’s James Webb Space Telescope have observed a massive helium cloud escaping from the super-puff exoplanet WASP-107b, marking the first direct detection of such atmospheric loss. Webb’s infrared data reveal an enormous exosphere nearly ten times the planet’s radius, with helium streaming both ahead of and behind the plane...

Astronomers Spot First Coronal Mass Ejection from a Distant Star, Raising Questions About Planetary Habitability
Astronomers detected the first coronal mass ejection from a distant star, revealing that powerful stellar eruptions may strip atmospheres from nearby planets, affecting exoplanet habitability and the search for life.

Webb Finds Phosphorus-Bearing Gas in an Ancient Brown Dwarf
NASA’s James Webb Space Telescope has detected phosphine (PH₃) in the atmosphere of the ancient brown dwarf Wolf 1130C, about 54 light-years away in Cygnus. This marks the first confirmed detection of a phosphorus-bearing gas in such a metal-poor object. The finding surprises astronomers, as phosphine was previously undetected in similar brown ...

Astronomers Stunned By Three Earth-Sized Planets In Distant Unique Planetary System
The study revealed that TOI-2267 has two closely bound stars orbiting each other, and the third planet transits the companion star.

JWST Delivers First-Ever Weather Report of Rogue Brown Dwarf World Glowing With Auroras
Astronomers using JWST have delivered the first weather report of SIMP-0136, a rogue brown dwarf about 20 light-years away. The study revealed stable silicate clouds, auroras heating the upper atmosphere, and possible giant storm systems. Findings mark a breakthrough in studying alien weather and pave the way for mapping exoplanet climates.

Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

A Planet with a Death Wish: How HIP 67522 b Is Forcing Its Star to Explode
NASA-backed astronomers have identified HIP 67522 b, a Jupiter-sized planet orbiting extremely close to its star, causing massive magnetic explosions. For the first time, a planet has been shown to trigger solar flares on its host star, highlighting a new era in exoplanet and stellar magnetic research.

James Webb Telescope Captures First Direct Image of Saturn-Mass Exoplanet
NASA’s James Webb Space Telescope has reached a major milestone by capturing its first direct image of TWA 7 b, a newly discovered Saturn-mass exoplanet orbiting the young star TWA 7. Using a coronagraph to block starlight, Webb identified the planet embedded in the star’s dusty ring system. TWA 7 b is the smallest exoplanet ever imaged dir...

James Webb Telescope Maps Fiery Atmosphere of Turbulent Exoplanet WASP-121b
NASA’s James Webb Space Telescope has unveiled the turbulent history of WASP-121b, a scorching exoplanet distorted by its star’s gravity. New atmospheric data reveals unusual molecules like silicon monoxide and methane, shedding light on the planet’s violent migration and extreme climate. These findings challenge current models and enhance un...

JWST Captures Unseen Details of Exoplanets in HR 8799 and 51 Eridani Systems
The James Webb Space Telescope (JWST) has captured groundbreaking images of exoplanets in the HR 8799 and 51 Eridani systems. By modifying its coronagraphs, astronomers allowed more starlight to pass through, revealing clearer planetary details. The study, published in The Astrophysical Journal Letters, highlights the first successful detection of ...
