Dark matter may have been responsible for the comet strike that killed off the dinosaurs 66 million years ago, as well as other mass extinction events and geologic upheavals, according to one scientist.
Back in March, scientists operating the telescope BICEP2 announced that they may have found proof of the Big Bang that created the Universe, while others claimed that their findings could just as well be explained by light scattering off dust between the stars in the Milky Way. And now, new research has confirmed that dust has foiled their "breakthrough" discovery.
Meet the Milky Way's new neighbor, KKs3, a dwarf galaxy located almost seven million light-years away, new research describes.
Neutrinos are like the ghosts of the particle world, carrying no charge and interacting with electrons and protons in only the faintest ways. Now a new study suggests that the great majority of high-energy neutrinos that can be found in the Milky Way Galaxy may be coming from the large black hole at its center, implying that black holes are actually neutrino factories.
Scientists have finally solved the mystery behind the bizarre object floating in the center of the Milky Way Galaxy, according to a new study, putting to rest questions that have bugged them for years.
The starry Milky Way Galaxy, seemingly innocent, is secretly stealing from nearby dwarf galaxies, making them devoid of star-forming gas, according to new research.
Our Milky Way galaxy harbors a lot of dark matter, but new measurements show that there is actually half as much of the mysterious substance as previously thought, according to a new study.
Scientists have recently discovered "Laniakea," a massive supercluster of galaxies that is home to our own Milky Way galaxy, shedding light on the boundaries of our own cosmic neighborhood.
A series of pseudo-3D maps may help astronomers better understand the world outside our solar system, otherwise known as interstellar space. The maps pinpoint materials between stars in the Milky Way galaxy, and could help reveal the composition of these interstellar mediums.
There are some 100 million other places in the Milky Way galaxy that could support complex life, report a group of astronomers in the journal Challenges.
A new video, released by NASA, shows two super-dense neutron stars destroy each other in a cataclysmic cosmic merger event that eventually creates a black hole.
An international team of astrophysicists has released a map, the first of its kind, of the entire sky that charts the magnetic field shaping the Milky Way galaxy and helps in our understanding of the birth of the universe, or the Big Bang.
The newly discovered "hypervelocity star" may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious dark matter surrounding the galaxy, astronomers report.
Spiral galaxies may be much larger and more massive than previously believed, researchers at the University of Colorado Boulder reported in a new study conducted using the Hubble Space Telescope.
