A tiny galaxy, an ultracompact dwarf, has a feature that astronomers didn't expect to find. It turns out that this small galaxy harbors a supermassive black hole, suggesting that these huge black holes may be far more common than previously thought.
Private companies in the United States may just be saving the American space industry. NASA has announced that U.S. astronauts will travel to and from the International Space Station on American spacecraft provided by Boeing and SpaceX.
Why are there so many disc galaxies like our Milky Way in the universe? Astronomers may have found the reason, thanks to ALMA.
Scientists have made new strides when it comes to cataloguing the stars in our Milky Way galaxy. They've found that no fewer than 219 million stars are located in our home galaxy, revealing a bit more about the features of the Milky Way.
There may be evidence for past life on Mars. A Martian meteorite fragment that's about 1.3 billion years old may show that it was once possible that life existed on the Red Planet.
The European Space Agency's Rosetta mission is moving forward and now, scientists have managed to map the surface of the comet that's the target for the new mission.
NASA's Mars Curiosity rover continues its exploration of the Red Planet. Now, it's officially reached a major landmark: Mount Sharp.
Elliptical galaxies have long been considered as being made up of old stars that move randomly within them. Now, though, scientists have taken a closer look at giant elliptical galaxies and have made some new findings when it comes to how they move.
Scientists have discovered giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere, which paints a more complicated picture when it comes to Venus' magnetic environment.
It turns out that "hot Jupiters" have more of an effect on their host stars than scientists once though. Astronomers have found that these large, gaseous exoplanets can make their stars wobble when they pass through their own solar systems.
On Sept. 10, our sun ramped up its activity. The sunspot AR2158 erupted, producing an X1.6-class solar flare. Now, a double punch of CMEs may supercharge the Northern Lights.
