One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on […]

Scientists Create Color-Based Catalog of Earthly Life Forms to Help Search for Alien Biology

A hypothetical rendering of colorful plant life on a habitable exoplanet. Although most such alien life, if it exists, found with this technique may be microscopic, it illustrates how analysis of color could help scientists learn more about the physical nature of alien biology.

Astronomers Discover Ancient Terrestrial Exoplanets Around Neighboring Star

Artist’s concept of the recently discovered, tightly packed, and ancient exoplanetary system named Kepler-444. Astroseismic studies of the star’s oscillations, allowed astronomers to determine that it is the oldest planetary system discovered to date, with an age of approximately 11 billion years.

The Cassini mission to Saturn has been one of the most successful and exciting in all of space exploration history. That amazing spacecraft is now celebrating its 10th […]

Of Alien Life and Intelligence: Are We Ready for Contact? (Part 3)

A new study cautions that humanity isn’t yet ready to contact any extraterrestrial intelligence, while proposing that SETI should not be involved in transmitting any radio signals to other civilisations that might be out in the Universe. How accurate is this view? Image Credit: José Antonio Peñas/Sinc

“Imagine how foolish you would feel […]

Of Alien Life and Intelligence: Angels and Demons (Part 2)

Looking up at the night sky we have mostly imagined other intelligent civilisations in the Universe as being either humanity’s entirely benevolent, wise teachers or its malevolent conquerers. How possible is it to make contact with just such types of civilisations? Image Credit: ESO/B. Tafreshi

“Life, even cellular life, may exist out yonder […]

Of Alien Life and Intelligence: The Limits of Perception (Part 1)

The Very Large Array of radiotelescopes in Socorro, N.M. Radiotelescopes are being used for more than half a century in the search for extraterrestrial intelligence. Is this means of communication also employed by other intelligent civilisations, and, if so, could we understand and perceive their presence? Image courtesy of NRAO/AUI and Photographer Kelly […]
