Just in time for Halloween, NASA's Hubble Space Telescope has captured the ghostly glow of stars ejected from ancient galaxies that were ripped apart several billion years ago.
Astronomers may have learned a little bit more about the evolution of our universe. Scientists have found that galaxies may have settled into their current form about two billion years earlier than previously expected.
Scientists have developed a new technique for imaging extremely distant galaxies, which opens a new window into the early universe.
Massive black holes may just be blocking the formation of new stars in aging galaxies. Scientists have found that the radio-frequency-emitting particles that the black holes spew out can halt the creation of stars.
Scientists have learned a bit more about how the universe evolved by studying leaky galaxies. They've taken a closer look at large star-forming galaxies to measure radiation leaks to see how the first stars were formed.
NASA Hubble Space Telescope has captured a new image of the galaxy DDO 68 and has found that while at first glance it appears to be a recently-formed galaxy in our cosmic neighborhood, it could actually be far older.
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.
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.
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.
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.
Our Milky Way galaxy isn't alone. Astronomers have found that it's part of a newly identified and huge supercluster of galaxies, which have been dubbed "Laniakea," which means "immense heaven" in Hawaiian.
