A team of scientists led by astronomers at the University of California, Riverside has used NASA's Hubble Space Telescope to uncover the long-suspected underlying population of galaxies that produced the bulk of new stars during the universe's early years. The galaxies are the smallest, faintest, and most numerous galaxies ever seen in the remote universe, and were captured by Hubble deep exposures taken in ultraviolet light.

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.

Recent studies with the Karl G. Jansky Very Large Array add strong, new evidence to the theory that binary stars form when the disk of gas and dust orbiting one young star gravitationally fragments, forming a second young star.

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.

Scientists developed the 'Loss of the Night app' to quantify the illumination of the night sky caused by artificial light. The app, originally available in only German and English, has now been expanded to support 11 languages in order to get data from as many regions as possible.
