Latest Smithsonian Center for Astrophysics Stories
One of the key factors in the search for life on other worlds is a planet’s ability to sustain liquid water, and researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) have for the first time revealed that this possibility exists on the type of planets known as super-Earths.
New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in decades.
A group of astronomers working at the Harvard-Smithsonian Center for Astrophysics (CfA) has discovered a transiting exoplanet, named Kepler 421b, with the longest known year of any of the 1,800 exoplanets discovered so far.
Two worlds orbiting a distant star are about to become a snack of cosmic proportions. Astronomers announced on Monday that the planets Kepler-56b and Kepler-56c will be swallowed by their star in a short time by astronomical standards. Their ends will come in 130 million and 155 million years, respectively.
The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream.
Life in the universe might be even rarer than we thought.
Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work
A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.
Dark matter, the mysterious substance that comprises more than 85 percent of the universe, is unlikely to be made of primordial black holes due to the existence of neutron stars.
