The search for intelligent alien life reaches far beyond simply finding another habitable planet. Across the universe, scientists can look for signs that advanced civilizations may leave behind, from ...

Discover why humanity may be a cosmic anomaly, as we explore traits that set us apart and the implications for alien life.

Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...

When writer Isabel Klee’s dog, Simon—known on social media as Simon Sits—died in late July, she shared her grief with their millions of followers. Here, Klee recounts saying goodbye to Simon and how ...

Every college has its fair share of niche courses. But where students might see an easy A or a fun class, professors see unique ways to foster critical thinking and open mindedness. (The Dallas ...

Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ...

Scientists now have multiple lines of evidence that black holes exist. For example, we have images of an accretion disk of matter outside the event horizon. Aside from better understanding them, we ...

The search for alien radio signals has spent decades listening in a familiar part of the spectrum. A first-of-its-kind survey now suggests that unexplored higher frequencies could widen the hunt, ...

Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has focused on for decades. Reading time 3 minutes For over half a century, the ...
