JWST Reveals Salt Clouds in the Atmosphere of the ‘Pink Planet’ GJ 504b
Using just two hours of observations, JWST decoded the atmosphere of GJ 504b, a cool pink world 57 light-years away. Scientists detected water vapor, methane, ammonia, and carbon dioxide, while deep salt clouds helped explain the object's unusual appearance and temperature.

Astronomers Discover Two Galaxies That Appear to Lack Dark Matter
Researchers studying FCC 224 and FCC 240 in the Fornax Cluster found evidence that both galaxies contain surprisingly little dark matter. The discovery supports the idea that galaxy collisions can strip away dark matter and raises new questions about how galaxies evolve.

Scientists Find Dwarf Galaxy That May Have Been Absorbed By Milky Way Billions Of Years Ago
The discovery was made after scientists examined 20 metal-poor stars located on the Milky Way's galactic plane.

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

Andromeda XXXVI Discovery Sheds Light on Dark Matter Rich Dwarf Galaxies
Astronomers have discovered Andromeda XXXVI, an ultra-faint, dark matter-rich satellite of Andromeda Galaxy. This ancient system may be a fossil from the early universe, helping scientists study galaxy formation and dark matter.

Brown Dwarf Merger Could Create a New Star, Astronomers Discover
Astronomers have discovered a rare brown dwarf binary system undergoing mass transfer with an ultra-short orbit. The pair could either merge or gain enough mass to ignite fusion, potentially forming a new star and redefining how “failed stars” evolve.

Scientists Solve Mystery Of Puzzling Radio Pulses From Space
Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some clarity.

James Webb Captures Stunning Infrared Image of the Helix Nebula Eye of God
The James Webb Space Telescope has captured a detailed infrared image of the Helix Nebula, also known as the “Eye of God.” The glowing ring of gas around a white dwarf star reveals filaments and knots formed as stellar winds collide with older material, offering insight into the fate of Sun-like stars.

Astronomers Look to the Large Magellanic Cloud to Study How Stars Are Born
The Large Magellanic Cloud is a nearby dwarf galaxy glowing with star birth. Just 160,000 light-years away, it hosts vast nebulae like the Tarantula and historic events such as Supernova 1987A, offering astronomers a rare, close-up laboratory to study how stars form, evolve, and explode.

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.

Webb Finds Phosphorus-Bearing Gas in an Ancient Brown Dwarf
NASA’s James Webb Space Telescope has detected phosphine (PH₃) in the atmosphere of the ancient brown dwarf Wolf 1130C, about 54 light-years away in Cygnus. This marks the first confirmed detection of a phosphorus-bearing gas in such a metal-poor object. The finding surprises astronomers, as phosphine was previously undetected in similar brown ...

James Webb Space Telescope Detects Phosphine on Brown Dwarf Wolf 1130C
Using the James Webb Space Telescope, scientists have detected phosphine gas in the atmosphere of the brown dwarf Wolf 1130C, about 54 light-years away. The finding suggests phosphine can form in extreme, non-biological environments, challenging its status as a potential biomarker and reshaping how scientists search for alien 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

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.

Ursa Major III May Be a Star Cluster, Not a Dark-Matter Dwarf Galaxy
Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new ...
