Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published…
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that…
NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer,…
Description This pair of images shows stars observed by the SPARCS (Star-Planet Activity Research CubeSat) space telescope simultaneously in the near-ultraviolet, left, and far-ultraviolet, right. These observations were recorded on Feb. 6, 2026, three weeks after the cube satellite, or…
A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars.
At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets,…
Jan. 23, 2026 NASA’s TESS Returns to Science Observations NASA’s TESS (Transiting Exoplanet Survey Satellite) entered safe mode Jan. 15 and returned to normal science operations Jan. 18. The operations team determined the issue arose when TESS slewed to point…
Trained on data from NASA's exoplanet-hunting missions, the open-source ExoMiner++ deep learning model uses an advanced algorithm to validate new planets.
A new NASA spacecraft called Pandora is launching to study the atmospheres of exoplanets and their stars.
Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with…
