NASA's James Webb Telescope Observes Millions Of Stars Within 'Cigar Galaxy'
Astronomers note that M82's extreme starburst phase won't last forever. It is expected to continue for only a few hundred million years-a brief moment in cosmic time.

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.

JWST Watches HD 80606 bExoplanet Heat Up by 1,100 Degrees in Hours
The James Webb Space Telescope observed HD 80606 b undergo a dramatic temperature surge during its closest approach to its star. The data revealed extreme heating and detected methane and carbon dioxide, offering a rare look at how giant exoplanet atmospheres respond to intense stellar energy.

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.

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.
-
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.

Astronomers Use Webb Telescope to Study Exoplanet Surface Beyond Atmosphere
Using James Webb Space Telescope, astronomers directly measured heat from LHS 3844 b, revealing a dark, rocky surface with no atmosphere—more like Mercury than Earth—marking a breakthrough in studying exoplanet geology.

James Webb Space Telescope Reveals Cosmic Buckyballs in Distant Nebula
Using the James Webb Space Telescope, astronomers have mapped buckyballs in a distant nebula. These complex carbon molecules, arranged in a shell, could offer clues to the chemistry that underpins life in the universe.

Astronomers Revisit Exoplanet HATS-75 b Using James Webb Telescope. Here's What They Found
Astronomers noted that HATS-75 b thus joins the rare population of giant planets around M-dwarfs observed with JWST.

Scientists Identify 45 Earth-Like Planets Beyond Our Solar System
Using data from Gaia mission and NASA Exoplanet Archive, scientists identified 45 rocky planets in habitable zones. These worlds, including TRAPPIST-1 e and Proxima b, are prime targets in the search for extraterrestrial life.

Kepler-51 Super-Puff Planets Baffle Scientists as JWST Finds No Atmosphere Clues
The Kepler-51 system hosts three ultra-light “super-puff” planets with massive atmospheres and tiny cores. New JWST observations failed to detect atmospheric signatures, suggesting thick hydrocarbon haze and deepening the mystery of how such worlds form.

NASA's James Webb Space Telescope Confirms Asteroid 2024 YR4 Will Not Strike the Moon
New Webb observations refined asteroid 2024 YR4’s orbit, showing it will safely pass about 21,200 km from the Moon in December 2032. The earlier 4.3% impact probability has now been eliminated.
