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.
Astronomers have discovered one of the most distant galaxies to date. Not only that but the galaxy, which breaks the previous record holder by 200 million years, also serves as a cosmic magnifying glass, revealing new clues about the early universe.
Scientists have found that giant asteroid impacts may have played a huge role in the geological evolution of Earth.
Using the Fermi satellite, astronomers have spotted high energy gamma rays shooting from an exploding star.
Astronomers have long known that young protostars eject supersonic jets of gas from their north and south poles. Now, though, researchers have detected more than ever before--all at the same time.
Astronomers have made an unusual discovery. Using the Atacama Large Millimeter/submillimeter Array (ALMA), they've found wildly misaligned planet-forming gas discs around two young stars in the binary system HK Tauri.
