It turns out that massive galaxies don't expand by making their own stars. Instead, they gain weight by chomping on nearby galaxies. Scientists have found that monster galaxies tend to absorb smaller ones in order to grow larger.
Orbiting Uranus, Miranda appears to have experienced an episode of intense resurfacing that resulted in the formation of at least three remarkable surface features: polygonal-shaped areas called coronae. Now, scientists have taken a closer look at these coronae to learn a bit more about the moon.
Scientists have taken a closer look at what causes supernovas to glow with high-energy gamma rays, investigating what powers these energetic stellar remains.
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.
