Recently in the SETI Category


Over the past few years, astronomers have detected thousands of planets and planet candidates by observing their periodic transits in front of their host stars.

The F-type star KIC~8462852 has recently been identified as an exceptional target for SETI (search for extraterrestrial intelligence) observations.

Globular clusters are ancient stellar populations with no star formation or core-collapse supernovae. Several lines of evidence suggest that globular clusters are rich in planets.

Why did the emergence of our species require a timescale similar to the entire habitable period of our planet?

Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU).

"A globular cluster might be the first place in which intelligent life is identified in our galaxy," says lead author Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics (CfA).

Within the scheme of conformal cyclic cosmology (CCC), information can be transmitted from aeon to aeon.

Sensitive new telescopes now permit astronomers to detect the waste heat that is expected to be a signature of advanced alien civilisations that can harness enormous energies on the scale of the stellar output of their own galaxy.

We address the possibility that intelligent civilisations that destroy themselves could present signatures observable by humanity.
