Search for Life

Last summer, Harvard professor Avi Loeb claimed tiny pellets of iron came from beyond our solar system. But new analyses suggest that they likely originated much closer to home.

A new U.S. Space Force publication says that to operate safely in space, Guardians need to know exactly what is in orbit and where it came from —  but anomalous objects show that it's no easy task.

Researchers are taking seriously the idea that our first evidence of life elsewhere in the cosmos may come in the form of alien technology.

Researchers searching for evidence of extraterrestrial life are investigating the geological faults of Saturn’s largest icy moon, Titan, and Jupiter’s largest moon, Ganymede.

Over 1.6 million star systems have been scanned by Europe's LOFAR system so far, but E.T. hasn't been caught phoning home yet.

The Breakthrough Listen initiative has moved its headquarters to the U.K. to take advantage of the reams of data set to come from the Square Kilometer Array.

Superintelligences might reveal themselves through the technosignatures of their cosmic engineering projects.

Any potential alien messages could be too complicated for humans to understand, but AI trained to detect complex structure in communication could help decipher them for us.

For many anxious to throw light on unidentified anomalous phenomena, it's all about reliable, truth-revealing, and scientifically rigorous data collection.

AI is the way forward in the search for extraterrestrial intelligence, from detecting radio signals to finding technosignatures on planets.
