Nearby Super-Earth GJ 251 c Could Help Learn About Worlds That Once Supported Life, Astronomers Say
Astronomers discovered GJ 251 c, a super-Earth 20 light-years away. Its location in the habitable zone and rocky composition make it a top candidate for future searches for life beyond our solar system. The team, led by Suvrath Mahadevan and Corey Beard, said this discovery provides a clock for one of the best candidates to search for life's atmo...

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.

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.

NASA Telescopes Capture First-Ever Companion Star Orbiting Massive Red Supergiant Betelgeuse
Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations. Dubbed “Betelbuddy,” the discovery reveals an extreme binary system that challenges existing models of stellar evolution and may offer clues to Betelgeuse’s future.

James Webb Offers First Glimpse Into How Moons Are Built Around Distant Planets
The James Webb Space Telescope has detected carbon-bearing molecules in a moon-forming disk surrounding CT Cha b, a massive planet-like object orbiting a young star 625 light-years away. The discovery marks the first measurement of its kind and offers clues to how moons like those around Jupiter and Saturn might have formed.

Dead Star's Supernova Explosion Could Be Visible From Earth During Daytime, Study Predicts
When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

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.

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

Exoplanets Explained: How Astronomers Find Worlds Orbiting Stars Beyond the Sun
Exoplanets are planets orbiting stars outside our solar system, hidden by stellar glare and detected indirectly. Astronomers identify them by tracking star wobbles or dips in brightness during planetary transits. NASA’s Kepler mission revealed thousands, with TESS now expanding the search. These discoveries confirm that planetary systems are abun...

Astronomers Propose Rectangular Telescope to Hunt Earth-Like Planets
Astronomers are exploring a revolutionary space telescope design with a long, narrow primary mirror instead of a traditional circular one. A 20×1 m rectangular mirror concentrates resolution along its length, enabling it to separate Earth-like planets from their stars at ~30 light-years in infrared light. Rotating the telescope 90° captures plane...

Astronomers Observe Rare Supernova–Black Hole Interaction in Early Stages
In a groundbreaking discovery, astronomers observed SN 2023zkd, a supernova that may have been triggered by close interaction with a black hole. Featuring unusual brightness peaks and extended pre-explosion activity, the event offers new insights into star black hole dynamics. Real-time AI detection played a key role, and upcoming surveys promise t...

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.

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.

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...
