Artist’s conception of GJ 1132b, an Earth-sized exoplanet orbiting a nearby star. Conditions on this world, however, are probably more like Venus than Earth. Image Credit: Dana Berry Astronomers have discovered another Earth-sized exoplanet that is the closest one to our own Solar System found so far, but it might not be a […] 
Does life spread through the galaxy like an infectious disease, with “bubbles” of inhabited planets? Image Credit: Harvard-Smithsonian CfA We still don’t know if there is life elsewhere in the universe, but scientists are working on techniques to better understand how it may have originated anyway, in the event that such alien biology […] Artist’s conception of Kepler-452b, the first near-Earth-sized exoplanet discovered orbiting in the habitable zone of a Sun-like star. Image Credit: NASA Ames/JPL-Caltech/T. Pyle One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is […] Illustration depicting the life cycle of Sun-like stars. Billions of years from now, our own Sun will expand into a red giant star, scorching any life that exists. Image Credit: ESO/M. Kornmesser Researchers at Cornell University are taking a new approach to the search for alien life: looking for habitable planets older than […] The Hubble Space Telescope has imaged what appears to be more than 160,000 star clusters in a group of galaxies known as Abell 1689. Image Credit: NASA, ESA, J. Blakeslee (NRC Herzberg Astrophysics Program, Dominion Astrophysical Observatory), and K. Alamo-Martinez (National Autonomous University of Mexico). On a day which yielded another historic announcement […] [youtube_video]http://youtu.be/6qr_0K7UPas[/youtube_video] Video courtesy of NASA In an effort to understand how black holes shape the evolution of galaxies, astronomers spent eight months creating a series of time-lapse movies from 400 observations made by NASA’s Hubble Space Telescope. The movies, taken from observations conducted over a 13-year period from 1995-2008, show a […] NASA’s IBEX spacecraft has detected the four-leaf-clover-shaped pattern of our Solar System’s “tail.” Image Credit: NASA Three years of observations by NASA’s Interstellar Boundary Explorer (IBEX) have shown that the Solar System has a tail shaped like a four-leaf clover. The stream of particles that blows away from the Sun, known […] The Andromeda galaxy, M31, observed by the now-retired ultraviolet space telescope GALEX. This composite image is false-colored, with blue representing far ultraviolet and orange representing near ultraviolet. Image Credit: NASA/JPL – Caltech. GALEX, the Galaxy Evolution Explorer, was recently decommissioned by NASA after more than 10 years of operation. GALEX was a space […] |

Another Look at Fermi’s Paradox
If intelligent alien life is so abundant, then where is it? Image Credit: NASA / HST
Enrico Fermi was a theoretical and experimental physicist known for his work on the first nuclear reactor and his contributions to quantum theory, particle physics, and statistical mechanics. He won the Nobel Prize in 1938 and was […]
