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

The primary challenge of rocket propulsion is the burden of needing to accelerate the spacecraft's own fuel, resulting in only a logarithmic gain in maximum speed as propellant is added to the spacecraft.

Wright et al. 2014 have embarked on a search for advanced Karadashev Type III civilisations via the compilation of a sample of sources with extreme mid-IR emission and colours.

If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxies.

The Breakthrough Prize Foundation and its founder, internet investor Yuri Milner, have signed a contract with the University of California, Berkeley, to lead a major escalation in the search for extraterrestrial intelligence, or SETI.

After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced civilizations in them.

Astronomers have expanded the search for extraterrestrial intelligence into a new realm with detectors tuned to infrared light. Their new instrument has just begun to scour the sky for messages from other worlds.

The vast collecting area of the Square Kilometre Array (SKA), harnessed by sensitive receivers, flexible digital electronics and increased computational capacity, could permit the most sensitive and exhaustive search for technologically-produced radio emission from advanced extraterrestrial intelligence (SETI) ever performed.

When astronomers conducting the search for extraterrestrial intelligence (SETI) find other cultures in the universe, could we understand their messages?

One of the beneficial outcomes of searching for life in the Universe is that it grants greater awareness of our own problems here on Earth.
