Astronomers Discover "Inside-Out" Planetary System With Rocky World Beyond Gas Planets, Challenging Formation Theories
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

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...

Astronomers Record First-Ever Massive Stellar Blast Capable Of Stripping Planetary Atmospheres
This event originated from a red dwarf star, which is much dimmer, cooler, and smaller than the Sun.

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.

Newly Found ‘Super-Earth’ GJ 251 c Could Be One of the Most Promising Worlds for Alien Life
A new super-Earth, GJ 251 c, has been found orbiting a nearby red dwarf star within its habitable zone. About four times Earth’s mass, it may host liquid water. Detected via the radial-velocity method using Penn State’s Habitable Zone Planet Finder, it’s a prime target in the search for life.

UY Scuti Reigns as the Universe’s Biggest Known Star, but Its Crown May Be at Risk
UY Scuti, a red hypergiant about 1,700 times the Sun’s radius, is the universe’s largest known star. Nearly 5 billion suns could fit inside its volume, but rivals like NML Cygni and Westerlund 1-26 challenge its claim to the crown. Astronomers stress that size estimates carry large uncertainties, leaving the title of biggest star still conteste...

Exoplanet 35 Light-Years Away Offers Hope for Life Beyond Earth
The exoplanet has a minimum mass 2.8 times that of Earth and has been categorised as a super-Earth.

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 ...
