Astronomy TOP STORIES
Some of the most breathtaking views in the Universe are created by nebulae hot, glowing clouds of gas.
Brown dwarfs are relatively cool, dim objects that are difficult to detect and hard to classify.
The chemical element lithium has been found for the first time in material ejected by a nova.
Two undergraduates at San Jose State University have discovered two galaxies that are the densest known.
Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of how it happens.
Beneath the vivid hues of this eye-shaped cloud, named Abell 78, a tale of stellar life and death is unfolding.
A ripple in the outskirts of the Milky Way -- and a hunch -- led Rochester Institute of Technology astrophysicist Sukanya Chakrabarti to a previously undetected dwarf galaxy hidden under a veil of dark matter.
Astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered jets of material ejected by still-forming young brown dwarfs.
A fast-moving pulsar appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at a speed of about 4 million miles per hour.
The Atacama Large Millimeter/submillimeter Array (ALMA) has been used to detect the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe.
Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova.
A team led by Andrea Kunder from the Leibniz Institute for Astrophysics Potsdam (AIP) measured the velocity of a sample of 100 old RR Lyrae stars* thought to reside in the galactic bulge, the central group of stars found in most galaxies.
The constellation of the great ship Argo Navis used to bob along the watery southern horizon of the Mediterranean during times of antiquity.
Sibling suns -- made famous in the "Star Wars" scene where Luke Skywalker gazes toward a double sunset -- and the planets around them may be more common than we've thought, and Cornell University astronomers are presenting new ideas on how to find them.
Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279.
This little-known galaxy, officially named J04542829-6625280, but most often referred to as LEDA 89996, is a classic example of a spiral galaxy.
NOAO scientists, using the Gemini Observatory 8-meter telescope in Chile, have obtained the highest resolution image ever obtained for the planetary nebula NGC 2346.
