When it comes to one particular type of star, "hot" doesn't even begin to explain how heated it becomes. Now, scientists have discovered the reason why small, unusually hot blue stars rise to scorching temperatures.
Scientists have announced that its Rosetta mission will be extended until the end of September 2016, and that the spacecraft will actually be landed on the surface of Comet 67P/Churyumov-Gerasimenko.
Black holes may actually be ideal labs for studying dark matter
Astronomers have discovered a staggering number of more than 800 dark galaxies in the famous Coma Cluster. The "ultra dark galaxies" may reveal a bit more about these mysterious features in space.
Scientists may have figured out a way to detect biosignatures of life on other worlds. They've found that if organisms with nonphotosynthetic pigments cover enough of a planet's surface, their spectral signal could be detected by powerful future telescopes.
NASA's New Horizons spacecraft has captured new images of the icy world of Pluto and its moon, Charon. The new pictures reveal strange dark spot on Charon's pole.
Mars may be sporting a "hairstyle" that's sure to make other planets jealous. NASA's MAVEN spacecraft has discovered that the Red Planet sports a "Mohawk" of escaping atmospheric particles at its poles.
On Monday, the sun unleashed a mid-level solar flare, which peaked at around 2:23 EDT. Yet this flare has had further repercussions. It's helped launch a massive geomagnetic storm on Earth.
Scientists have managed to determine the mass of a tiny binary star thanks to some intense radio emissions.
NASA has taken a closer look at the "teenage years" of quasars. Using the Hubble Space Telescope, astronomers have uncovered the early formative years of the brightest objects in the universe.
NASA's New Horizons spacecraft has beamed back the first ever color movies of Pluto and its largest moon, Charon. The new video reveals the complex dance of the two bodies, known as a double planet.
