Understanding the birth of our sun has long been a source of study for researchers. Now, they may be a step closer. Scientists have investigated the solar system's prehistoric phase and the events that led to the birth of the sun.
The loneliest supernovae in the universe are likely created by the collisions of white dwarf stars and neutron stars--at least, that's what a new study suggests.
Astronomers have spotted a stream of gas that's a staggering 2.6 million light years long with the help of the William E. Gordon Telescope.
NASA's Hubble Space Telescope has made a surprising discovery. It's spotted a star system that may have left behind a "zombie star" after a supernova explosion that should have destroyed it.
The VLT Survey Telescope (VST) has captured a spectacular new image of the galaxy, Messier 33. The picture reveals the nearby spiral, the second closest galaxy to our own Milky Way.
Pluto may just be the guiding "star" that NASA's spacecraft needs. Astronomers are using ALMA to make high-precision measurements of Pluto's location and orbit in order to help guide the New Horizons spacecraft to its target.
The European Space Agency's comet-chasing spacecraft Rosetta finally arrived at its destination comet after a decade-long journey.
Can you imagine a planet beginning its life as a star? Astronomers have spotted an extremely cool, planet-like object that probably spent much of its youth as hot as a star.
Three massive volcanic eruptions on Jupiter's moon, Io, have made astronomers think twice about how often these outbursts occur.
You'd think that the sun's surface would be hotter than its outer atmosphere, but that's not the case. In fact, it's a phenomenon that has puzzled scientists for decades. Now, they may have the answer; new observations reveal that it may have something to do with nanoflares.
Scientists have taking another step toward discovering life on other planets; they've found that companion planets may extend the chance for life on Earth-sized planets in the cosmos.
The next NASA rover is slated to explore Mars as never before. Planned to be sent to the Red Planet in 2020, the new rover will carry seven carefully-selected instruments that will conduct unprecedented science and exploration technology investigations.
