NASA's Webb Telescope Captures Clearest Picture Yet Of Exoplanet Surface
NASA's James Webb Space Telescope gathered data on a rocky exoplanet with a diameter about 30% larger than Earth - called LHS 3844 b, or Kua'kua.

James Webb Telescope Observes Distant Exoplanet That Looks Like Giant Mercury
Without an atmosphere to shield it, LHS 3844 b is bombarded by stellar radiation and micrometeorites.

Explainer: Why Pluto Lost Planet Status As NASA Chief Urges Reconsideration
NASA Administrator Jared Isaacman has reignited the two-decade-old debate over Pluto's classification by publicly backing its reinstatement as a full planet, while NASA prepares scientific papers to challenge the International Astronomical Union's 20

NASA Chief Calls For Making Pluto A Planet Again At US Senate Hearing
He also said that NASA is working on research papers that they would like to bring forward within the scientific community to revisit the discussion.

'Forbidden Planet' The Size Of Jupiter That Shouldn't Exist In Theory Baffles Scientists
TOI 5205b is called a 'forbidden planet' as it defies current astronomical theories about planetary formation.

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.

NASA's James Webb Telescope Reveals Helix Nebula In Stunning Detail, Showing How Dying Stars Seed Future Planets
Previous Spitzer studies have indicated the formation of complex molecules in the Helix Nebula.

VLT’s GRAVITY Instrument Detects ‘Tug’ from Colossal Exomoon; Could Be Largest Natural Satellite Ever Found
Astronomers have spotted a subtle orbital wobble around the massive exoplanet HD 206893 B, hinting at the presence of a gigantic moon nearly half Jupiter’s mass. If confirmed, it would be unlike any moon known, potentially redefining how scientists distinguish between moons, planets, and brown dwarfs.

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 Detect "Super-Earth" Just 18 Light-Years Away In Habitable Zone
Researchers at UC Irvine and their partners published their study in The Astronomical Journal.

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.

White Dwarf Gobbles Up Nitrogen-Rich Ices of Pluto-Like World
Astronomers have observed a white dwarf, a highly compact stellar ember, that appears to have gobbled up an icy world akin to dwarf planet Pluto, a finding with implications regarding the likelihood of habitable planets beyond our solar system

Hubble Spots White Dwarf Devouring Icy Pluto-Like Planet 260 Light-Years Away
Using Hubble’s ultraviolet spectrograph, scientists detected carbon, nitrogen, sulphur, and abundant oxygen falling onto a white dwarf 260 light-years away, evidence of an icy planetesimal being torn apart. The find shows volatile worlds can persist into a star’s final stages, offering a preview of the Sun’s distant fate.
