Students in a University of Maryland undergraduate astronomy class made a discovery that wowed professional astronomers: a previously unstudied asteroid is actually a pair of asteroids that orbit and eclipse one another. Fewer than 100 binary eclipsing asteroids have been found in the main asteroid belt.

An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.

Striking new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust. If enough of this dust makes the perilous transition into interstellar space, it could explain how many galaxies acquired their dusty, dusky appearance.

The discovery of a millisecond pulsar in a triple system with two white dwarfs gives astronomers the most precise tool yet for studying the gravitational three-body problem. In addition, the nature of the stars and their interactions may give an unprecedented clue that points toward a new theory of gravity compatible, unlike general relativity, with quantum theory.

Massive stars present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller? To find the answer, astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to survey the cores of some of the darkest, coldest, and densest clouds in our Galaxy to search for the telltale signs of star formation.

This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our Sun and 200 times larger.
