Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all. picked by 2manyusernames 2 years ago

Carl Sagan brings us the Cosmos, everything that ever was and ever will be, in an approach that is easily accessible even for those of us that are not science wizards. This series covers everything from the history of astronomy, the challenges it faced at its creation, how the universe was created and how it all might end, to the evolution of life on Earth, and the nature of the human brain. picked by yoornotme 2 years ago

Thanks to the Hubble Space Telescope we know the universe is 13.7 billion years old. The HST has helped scientists determine the process of how planets are born and detected the first organic molecule on a planet outside our solar system. These first snapshots from the newly repaired Hubble showcase the 19-year-old telescope's improved vision. picked by equinox 3 months ago

Have movies like Transformers or Star Wars tractor-beamed the genre of science fiction away from perceived as serious literature, even in the book world? And which giant battle cruiser of a movie deserves the most blame for turning the genre into an amusement park ride instead of an exploration of our place in the universe? Vote for your scapegoat here. picked by lostsoul135 2 years ago

Long ago, antimatter all but vanished from existence, allowing matter to predominate and form the stars and planets of the universe. Exactly why this happened has been a mystery, but a particle accelerator in Japan may have found a new clue, and one that does not seem to fit the standard model of particle physics. picked by AutumnLotus 2 years ago

Scientists don't know what dark energy is, but they observe its tugging effect, which causes the expansion of the universe to accelerate. Now they have seen this mysterious force in some of the largest known features of the cosmos, called superclusters and supervoids. picked by AutumnLotus 1 year ago

The most massive black hole in the universe tips the cosmic scales at 18 billion times more massive than the sun, astronomers suggest today at a meeting of the American Astronomical Society. Even though researchers suggested black holes up to this mass might exist in quasars, this is the first direct confirmation of such a behemoth. picked by AutumnLotus 2 years ago

Astronomers have discovered an unexpected cache of spiral galaxies that appear to have formed recently, long after the period early in the history of the universe that most galaxies were thought to have been created. picked by AutumnLotus 7 months ago

The scientists at the European Organization for Nuclear Research, known as CERN are getting ready to see the universe born again. Again and again and again — 30 million times a second, in fact, as they hope to unlock the secrets of the universe and its building blocks. picked by 2manyusernames 3 years ago

Perhaps the first stars in the newborn universe did not shine, but instead were invisible “dark stars” 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter. The study calculated how the birth of the first stars almost 13 billion years ago might have been influenced by the presence of dark matter – the unseen, yet-unidentified stuff tha... read full post picked by AutumnLotus 2 years ago

When astronomers think about the Big Bang, in general they don’t actually mean that one singular moment when the Universe burst into being. It’s really the name given to the model used to describe what happened an infinitesimally thin slice of time after that moment. picked by mariusz712 2 years ago

Mathematicians have proposed an alternative explanation for the accelerating expansion of the universe that does not rely on the mystifying idea of dark energy.

According to the new proposition, the universe is not accelerating, as observations suggest. Instead, an expanding wave flowing throughout space-time causes distant galaxies to appear to be accelerating away from us. picked by AutumnLotus 3 months ago
