A detailed survey of stars in the Orion Nebula has found that fewer than 10 percent have enough surrounding dust to make Jupiter-sized planets, according to a report by astronomers at the University of California, Berkeley, the California Institute of Technology (Caltech) and the Harvard-Smithsonian Center for Astrophysics.

On April 9, the Sun erupted and blasted a bubble of hot, ionized gas into the solar system. The eruption was observed in unprecedented detail by a fleet of spacecraft, revealing new features that are predicted by computer models but difficult to see in practice.

Astronomers have discovered that rocky, terrestrial planets might orbit many, if not most, of the nearby sun-like stars in the disk of our galaxy. These new results suggest that worlds with potential for life are more common that we thought.

Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from NASA's Spitzer Space Telescope. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions to our own solar system.

170 light-years away from earth exists a particularly puzzling orbiting object. This object, 2M1207B, seems to be physically impossible. Nothing about it matches any established astronomical theory.

The Sun is minimally active right now, but this quiet state of affairs won't last for long. Over the next few years, the number of solar flares and eruptions known as coronal mass ejections will increase until reaching solar maximum in 2011 or 2012.

Astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other.

Using two NASA satellites, astronomers have discovered a black hole that obliterates a record announced just two weeks ago. The new black hole, with a mass 24 to 33 times that of our Sun, is the heftiest known black hole that orbits another star.
