By combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-light imagery from the NASA/ESA Hubble Space Telescope,...
By comparing new Hubble observations with images first taken in 1999, astronomers traced the continuing expansion of one of the sky’s most studied supernova...
The breakup of C/2025 K1 (ATLAS), captured by the NASA/ESA Hubble Space Telescope, opens a window into how fragile comet nuclei evolve and collapse.
These...
Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the coolest transiting planet in this...
New observations of L 98-59d, a member of the five-planet system L 98-59, suggest it harbors a vast global magma ocean that traps sulfur deep inside, forming...
Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint...
New measurements show that the DART impact in 2022 not only shortened the orbit of the moonlet Dimorphos around its parent asteroid, Didymos, but also...
The NASA/ESA/CSA James Webb Space Telescope conducted a clockwise scan around the entire limb of Jupiter, chasing aurora as it rotated into view. This...
New images from the NASA/ESA Hubble Space Telescope and ESA’s Euclid mission have revealed the complex, multi-shell structure of the extraordinary planetary...

The unmatched sensitivity of the NASA/ESA/CSA James Webb Space Telescope in both near- and mid-infrared light sheds new light on PMR 1, a little-studied...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have produced a spectacular infrared image of the spiral galaxy NGC 5134.
This Webb image...
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova — a red supergiant...
For the first time, astronomers have mapped the vertical structure of Uranus’ ionosphere, uncovering unexpected temperature peaks, weakened ion densities,...
The new dark galaxy candidate is dominated by dark matter and nearly devoid of light. Named Candidate Dark Galaxy-2 (CDG-2), the object consists of four...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
The Chandra team has released a striking new composite image of the Cocoon Nebula, a reflection and emission nebula in the constellation of Cygnus. The...
Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest...
