The sheer scale of Carrazco-Gaxiola’s survey, titled “An All-Sky Spectroscopic Reconnaissance of More Than 2,100 K Dwarfs Within 40 Parsecs Using High-Resolution Spectra,” is what sets it apart.

Radio telescopes have long scanned quiet patches of sky for a lone, artificial-sounding ping, but a growing body of research is pushing astronomers to look instead at the loudest neighborhoods in the ...

Comet 3I/ATLAS is only the third known object to barrel into our neighborhood from interstellar space, and it is already shredding old assumptions about how comets form, move, and even what they are ...

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

Scientists have found new evidence suggesting that interstellar 3I/ATLAS is not an alien spaceship, as one conspiracy theory claims, but a comet.

Astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spacecraft. 3I/ATLAS was confirmed as the third known object to enter our solar system from interstellar ...

In July, researchers using the NASA-funded Asteroid Terrestrial-impact Last Alert System survey telescope in Chile made an exceedingly rare discovery: a mysterious object passing through the solar ...

Wafer probe, one of the key processes for ensuring reliability in semiconductor manufacturing, is becoming increasingly unreliable in multi-die assemblies and at leading-edge nodes. For much of the ...
