A new study has revealed that Andromeda had more violent history, as scientists found a more disordered stellar population than our Milky Way, suggesting that it may have been bombarded by smaller galaxies.
By analysing X-rays emitted by two celestial objects, scientists have detected an unusual signal that could be of a particle of dark matter, offering hope for a tangible evidence for the existence of dark matter in the universe.
NASA's Hubble Space Telescope has recently spotted a diminutive object that is estimated to be over 13 billion light-years away; this is supposed to be one of the farthest, faintest, and smallest galaxies ever seen.
Earth is one of some 40 billion potentially habitable worlds in the galaxy -- with about one new life-friendly planet forming every year, a study has revealed, adding that our Milky Way may be home to some 3,000 extra-terrestrial civilisations.
A team of astronomers has demonstrated that our own galaxy, the Milky Way, is part of a newly identified ginormous super cluster of galaxies, dubbed as "Laniakea", meaning "immense heaven" in Hawaiian.
