Latest Smithsonian Center for Astrophysics Stories
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.
Astronomers have discovered a giant star-forming region located 36,000 light-years away from Earth shining 100 times brighter than the Orion nebula.
Extremely quick, extremely bright radio pulses known as “fast radio bursts” may originate from flaring stars located within our own galaxy, researchers from the Harvard-Smithsonian Center for Astrophysics claim in a new study.
A star exploded more than 12 billion years ago, ripping itself apart and blasting debris outward in twin jets at nearly the speed of light. The star shone so brightly at its death that it outshone its entire galaxy by a million times.
A gamma-ray burst (GRB) created by the collision of two neutron stars has given researchers new insight into how gold, one of the rarest elements on Earth and in the entire universe, is formed.
Our Sun erupted on June 7, 2011, sending tons of hot plasma blasting into space. Some of the plasma fell back to the surface of the Sun, sparking bright flashes of ultraviolet light. A new study examines the dramatic event to provide new insights into how young stars grow by consuming nearby gas.
Astronomers have discovered an unprecedented number of black holes in the Andromeda Galaxy (M31), one of the Milky Way’s nearest cosmic neighbors, using data from NASA’s Chandra X-ray Observatory.
Researchers from the Harvard-Smithsonian Center for Astrophysics have blended science, technology and art to create a unique new website that allows people to listen to original musical compositions crafted from cosmic x-rays.
Astronomers using NASA's Kepler space telescope have found that six percent of red dwarf stars have habitable, Earth-like planets.
