The discovery of these stellar twins could provide invaluable insight into the formation and evolution of massive stars, close binaries, and star nurseries.
Astronomers are discovering that some type Ia supernova explosions may not be as symmetric as previously thought.
The discovery provides important insight on how supermassive black holes can have a catastrophic effect on the galaxies in which they reside.
Direct observations of this process give strong support to one of several suggested pathways to producing such systems.
The European Space Agency’s Intermediate eXperimental Vehicle flew a flawless reentry and splashed down in the Pacific today.
The orbiter is investigating seasonal and longer-term changes, including some warm-season flows that are the strongest evidence so far for liquid water on Mars today.
A resurgence of support from the University of California and several large donations signal a turning of the tide for the world’s first permanent mountaintop observatory.
In a world first, the European Space Agency will launch and land an unmanned spaceplane February 11 that has no wings but instead features an aerodynamic shape that produces the lift to fly through the atmosphere.
A team of astronomers has discovered a close pair of white dwarf stars in a planetary nebula that have a total mass of about 1.8 times that of the Sun.
Preliminary results suggest the area had acidic ancient conditions
The latest data release is providing insights on the first stars, dark energy, and cosmic structure.
Explorers are excited because these deposits could be mined if they are sufficiently abundant.
These so-called Galilean satellites complete orbits around Jupiter with durations ranging from two to 17 days.
These are the first photos of the Pluto system for the spacecraft's optical navigation phase of the mission.
The February 14 flyby will allow the spacecraft to sample the innermost parts of Comet 67P/Churyumov-Gerasimenko’s atmosphere.
They are the first such stars found that lie in the central plane of the Milky Way beyond its central bulge.
Victor Aniceto, former vice president of sales and marketing, will succeed Joe Lupica.
