New Study Shows How Salts Could Make Liquid Water on Mars

The Phoenix lander was the first mission to land near the Martian north pole. Was it also the first to see evidence of liquid water on Mars? Image Credit: NASA/ JPL-Caltech/University of Arizona/Texas A&M University

The search for evidence of water on Mars, past or present, has been one of the driving forces behind [...]

As the number of exoplanets discovered continues to grow exponentially, the number of potentially habitable worlds out there continues to increase as well. Astronomers have now reported finding another one of the nearest known of these kinds of planets so far, Gliese [...]

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 if [...]

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 in [...]

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?

Europa and Enceladus, for good reason, have captured the attention and imagination of those searching for evidence of life elsewhere in our Solar System. Both moons are now thought to have subsurface oceans with conditions where [...]

Studying the Light of Alien Atmospheres With NESSI

A new multi-object, near-infrared spectrograph, installed on the Magdalena Ridge Observatory’s 2.4-m Telescope, will study the atmospheres of extrasolar planets located relatively close to Earth, allowing astronomers to probe their chemical composition. Image Credit: MRO

Exoplanetary astronomy has been one of the most productive scientific endeavors in recent years, with new discoveries of planets [...]

Bathed in Crimson Light: New Exoplanet Discoveries and the Prospect of Habitability Around Red Dwarf Stars

An artist’s impression of a sunset on Gliese 667 Cc, a habitable Super Earth-sized planet around the triple star system Gliese 667, located 22 light-years away from Earth. Are views, such as this envisioned here, common on planets around red dwarfs stars in the galaxy? Image Credit: ESO/L. Calçada
