Scientists May Have Solved the Missing Sulfur Mystery in Star-Forming Clouds
A new simulation suggests sulfur in star-forming clouds may be locked inside icy dust grains through previously overlooked chemical reactions. The findings offer fresh clues to a decades-old cosmic mystery and could improve our understanding of life's essential ingredients in space.

Astronomers Discover Why Massive Galaxies Died Early in the Universe
Astronomers have discovered a powerful galactic wind in the merging galaxy system CRISTAL-02. The outflow is removing star-forming gas faster than it can be replenished, providing the first direct evidence for a mechanism that may have shut down star formation in massive early galaxies.

JWST Reveals the True Identity of Mysterious Little Red Dots
Using JWST, astronomers obtained the most detailed spectrum yet of a little red dot and found evidence that these mysterious objects are rapidly growing black holes wrapped in dense gas. The discovery could explain why they appear, shine red, and eventually disappear from the cosmic record.

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.

NASA's Hubble Space Telescope Captures Two Galaxies Locked In A Stellar Interaction
The image is part of a collection of 59 photographs of merging galaxies taken by the Hubble Space Telescope.

James Webb Space Telescope Weighs Most Distant Dormant Black Hole Ever Detected
Using JWST and a natural gravitational lens, astronomers measured a six-billion-solar-mass dormant black hole more than 10 billion light-years away. The discovery offers a rare glimpse into how galaxies and black holes evolved when the universe was just three billion years old.

James Webb Space Telescope Detects Most Distant Dormant Black Hole Ever Found
JWST has identified the most distant dormant black hole ever observed, a six-billion-solar-mass giant in galaxy MRG-M0138. Seen when the universe was only three billion years old, the discovery provides rare evidence that black holes and galaxies evolved together in the early cosmos.

SETI Scientists Searched Interstellar Comet 3I/ATLAS for Alien Signals
SETI researchers used the Allen Telescope Array to scan interstellar comet 3I/ATLAS for artificial radio signals. No techno-signatures were detected, but the observations improved methods for future searches.

NASA's James Webb Space Telescope Detects Methane On Interstellar Comet For First Time, Reveals Unusual Chemistry
The observations further confirmed that comet 3I/ATLAS remains unusually rich in carbon dioxide.

Study Reveals Some Supermassive Black Holes May Have Been Born Big
According to researchers, some of these black holes may have formed without first going through a stellar collapse phase.

NASA's Hubble Telescope Spots 'Gomez's Hamburger', A Distant Star Wrapped In Dust
Located about 6,500 light-years away in the constellation Sagittarius, Gomez's Hamburger has already expelled large amounts of gas and dust.

JWST Discovers Ancient Black Hole Older Than Its Own Galaxy
JWST has identified a supermassive black hole from the early universe that outweighs most of its own galaxy, suggesting black holes may form before galaxies themselves.

Most Powerful Neutrino Ever Detected May Have Come From a Blazar
A 220 PeV neutrino detected beneath the Mediterranean Sea may have originated from a distant blazar. Simulations suggest these powerful black hole systems can generate ultra-high-energy ghost particles.

NASA's Hubble Telescope Spots Mysterious Dim Galaxy Hidden In Space
Scientists believe galaxies like UGC 477 are largely dominated by dark matter.

James Webb Telescope Probes Universe's Most Distant 'Hot DOG', Shares Details
The results point to more than the usual dusty ring around the black hole, known as the AGN torus.
