Astronomers have discovered that the flattened clouds of gas and dust around stars — nurseries that give birth to planets — are generally smaller than previously thought. Some are so small, in fact, ...

Growing up is hard to do, especially for baby planets. Now, scientists may have uncovered the solution to one puzzle about protoplanetary growing pains. An obstacle to planetary formation, known as ...

Astronomers have been searching the skies using the Atacama Large Millimeter/submillimter Array (ALMA) to study orbital geometries and protoplanetary disks that surround binary stars. The team found ...

WASHINGTON, D.C. — New observations of the Orion Nebula at infrared wavelengths reveal that small dust grains located in disks around young stars are growing, taking the initial steps toward forming ...
