Astronomers Find Thin Atmosphere Around Distant Frozen Space Object
Researchers believe the discovery could provide new insights into how atmospheres form.
-
Astronomers Discover Trans-Neptunian Object With Atmosphere in Outer Solar System
Astronomers discovered a faint atmosphere around (612533) 2002 XV93 using a stellar occultation. The finding challenges current theories, as such small, cold bodies should not retain gas, hinting at recent activity like impacts or ice volcanism.
-
Astronomers Discover 27 Potential "Tatooine-Like" Planets Orbiting Two Stars
The potential planets were detected using data from NASA's Transiting Exoplanet Survey Satellite.
-
New Einstein Cross Reveals Surprising Galaxy Evolution
Astronomers discovered a rare Einstein Cross around galaxy J1453g, revealing a stellar structure similar to the Milky Way. The finding challenges current theories of how elliptical galaxies form and evolve.
-
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.
-
New Study Claims There Might Be Way More Pulsars in Space Than We Previously Thought
Astronomers have discovered that fast-spinning pulsars emit radio waves far beyond their magnetic poles, reaching the edges of their magnetic fields. The finding challenges long-held theories and could help scientists discover more pulsars and improve gravitational wave detection.
-
Hubble Telescope Captures Comet Reversing Its Rotation for the First Time
Using the Hubble Space Telescope, astronomers observed Comet 41P slow, stop, and reverse its spin due to gas jets. The rare phenomenon could mark the beginning of the comet’s breakup as it nears the end of its life.
-
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.
-
Ancient Star in Pictor II Reveals Secrets of Early Universe
Astronomers have discovered one of the oldest known stars, PicII-503, in the Pictor II dwarf galaxy. With extremely low iron content, the star offers rare insight into the second generation of stars and the early chemical evolution of the universe.

Chandra Detects Giant X-Ray Bubble Around Young Sun-Like Star HD 61005
NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its stellar wind is far stronger than today’s solar wind, forming a 200 astronomical unit-wide astrosphere that offers rare insight into how the young Sun onc...

Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core
Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matt...

Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

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.
-
Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...
-
Astronomers Witness Rare Failed Supernova in Andromeda Galaxy
NASA’s NEOWISE infrared telescope has provided striking evidence that a massive star in the Andromeda galaxy collapsed directly into a black hole without exploding as a supernova. The star, M31-2014-DS1, faded dramatically in visible light while leaving a faint infrared glow from surrounding dust. Astronomers say this rare “failed supernova” ...
