JWST Reveals Powerful Winds and Dense Atmosphere on Scorching Exoplanet TOI-561b
Astronomers using NASA’s James Webb Space Telescope have found compelling evidence that TOI-561b, an ultra-hot rocky exoplanet orbiting its star every 11 hours, still retains a dense atmosphere. Temperatures measured on both its day and night sides are far lower than expected for a bare rock, implying powerful winds and efficient heat transport. ...

The Most Exciting Exoplanet Discoveries of 2025: Know the Strange Worlds Scientists Have Found
Astronomers marked a milestone year as confirmed exoplanets surpassed 6,000 in 2025. Discoveries ranged from planets orbiting two suns to worlds losing their atmospheres or forming in real time. The findings reshaped ideas about how planets form, survive, and evolve across the Milky Way.

JWST Detects Thick Atmosphere on Ultra-Hot Rocky Exoplanet TOI-561 b
Astronomers using the James Webb Space Telescope have discovered compelling evidence of a thick atmosphere surrounding TOI-561 b, an ultra-hot rocky exoplanet orbiting its star every 11 hours. Despite extreme radiation and molten surface conditions, the planet appears cooler than expected, suggesting heat-redistributing atmospheric winds and volati...

TRAPPIST-1e Methane Signal Likely False, Webb Data Suggests Airless Planet
The TRAPPIST-1 planetary system, located about 39 light-years from Earth, hosts seven rocky worlds orbiting a cool red dwarf star. While several of these Earth-sized planets lie in the star’s habitable zone, new observations from the James Webb Space Telescope suggest their atmospheres may be too thin to support life. Earlier hints of methane aro...

Mars Orbiter Tracks Interstellar Comet 3I/ATLAS With Unprecedented Precision
Scientists mapped the path of interstellar comet 3I/ATLAS with ten times greater accuracy using images from ESA’s Mars orbiter. The breakthrough shows how observations from different points in space can improve future planetary defense. The data, the first of its kind from another planet’s orbit, offers a powerful new tool for tracking fast-mov...

AI-Assisted Study Finds No Evidence of Liquid Water in Mars’ Seasonal Dark Streaks
A large-scale AI analysis of more than two million Mars orbiter images shows that the planet’s dark slope streaks form through seasonal dust avalanches, not flowing briny water. The results settle a long-running debate, revealing that wind-driven dust activity shapes Mars’ surface and offering new insights into the planet’s climate past and e...
