A 13-atom molecule containing sulfur has been discovered in interstellar space for the first time, providing insight into the origins of the chemistry of life.

The boundary of the Solar System remains somewhat poorly understood. We know we are within it, in a region of space called the heliosphere, where particles released by the Sun dominate. Beyond it, the ...

Using data collected by NASA's Parker Solar Probe during its closest approach to the sun, a University of Arizona-led ...

NASA’s Transiting Exoplanet Survey Satellite has once again surprised astronomers by tracking interstellar comet 3I/ATLAS, a ...

Comet C/2025 K1 (ATLAS) crumbled in high-resolution footage captured by the Gemini North telescope atop Mauna Kea in Hawaii. Glowing pieces of the comet are visible in the 8.1-meter diameter ...

During a close approach to the Sun, the European Space Agency’s Solar Orbiter watched that tipping point unfold in unusually fine detail. The spacecraft observed the M7.7-class flare—strong but still ...

All eyes have been on the nearly 5-6 km long exocomet, including NASA’s Transiting Exoplanet Survey Satellite, aka TESS.

The volcanic hot spot is larger than Lake Superior, spewing eruptions six times the total energy of all of the world's power plants.

During a special observation run from Jan. 15 to Jan. 22, the Transiting Exoplanet Survey Satellite ( TESS) repeatedly ...

This shifts our entire perspective on what makes a planet “Earth-like.” Nature is far more creative than our own solar system suggests. The universe might be teeming with “magma-shielded” worlds that ...
