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.

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 ...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

Astronomers Discover New Earth-Sized Planet Orbiting Jupiter-Sized Red Dwarf Star
This new extrasolar planet, or exoplanet, is named Speculoos-3b and is located relatively close to the Earth, just 55 light-years away.

Scientists Discover a New Planet Hidden in a Debris Disk of a Young Star
Astronomers have a found a new exoplanet hiding in the debris disk of a star. Dubbed as AU Mic b, the exoplanet was found after decades of search, around the red dwarf star, AU Microscopii that is roughly 32 light-years away.

Ultraviolet Light May Be Key To Finding Alien Life: Study
Ultraviolet light may have played a critical role in the emergence of life on Earth and could be a key to finding life elsewhere in the universe, a study led by an Indian-origin scientist at Harvard suggests.

Star Fight Between White Dwarf And Red Dwarf In Space
Astronomers have discovered a new type of exotic binary star system, in which a rapidly spinning white dwarf star is lashing the companion red dwarf star with high-energy particles, causing the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.

Venus-Like Planet Found 39 Light Years Away
Astronomers have discovered a new Venus-like rocky exoplanet 39 light years away, which may be cool enough to potentially host an atmosphere.

There's a New Earth-Size Planet in the Neighborhood (Galactically Speaking)
The yeoman work of NASA's Kepler Space Telescope has revealed our Milky Way galaxy to be lousy with planets - surely tens of billions of them, if you extrapolate from what Kepler has detected so far in a small patch of the sky.
