Researchers think that a galaxy's corona is a remnant of the primordial cloud of gas that collapsed to form the galaxy billions of years ago.
September 29, 2022Galaxies, such as the Milky Way, are the building blocks of the universe, each comprised of up to several hundred billion stars.
September 29, 2022Mexican scientist Carlos Frenk Mora is one of the world's best known astronomers for his theories on dark matter and its role in the formation of galaxies.
August 19, 2018One point seven billion is a big number. That’s how many stars have been mapped in the Milky Way, the galaxy that is home to our sun and our solar system. And if that doesn’t make you feel a bit insignificant, there are hundreds of billions of galaxies in the universe. City dwellers have lost …

May 20, 2018Our galaxy, which is home to Earth and its solar system, might not be as “typical” as previously thought, and therefore Milky Way-based models to understand other galaxies of the universe could be misleading, new research suggests. “We use the Milky Way and its surroundings to study absolutely everything,” said Marla Geha of Yale University …

September 22, 2017After conducting a cosmic inventory of sorts to calculate and categorise stellar-remnant black holes, astronomers have determined that the Milky Way is home to about 100 million of the enigmatic, dark objects — far more than expected. "We think we've shown that there are as many as 100 million black holes in our galaxy," said …

August 9, 2017The center of our Milky Way contains a "trap" that concentrates some of the highest-energy cosmic rays which are among the fastest particles in the galaxy, according to an analysis. The study combined high-energy observations from High Energy Stereoscopic System (HESS) — a ground-based observatory in Namibia — with lower-energy data from NASA's Fermi Gamma-ray …

July 19, 2017Our galaxy could have 100 billion brown dwarfs or more, according to a new research by an international team of astronomers. Brown dwarfs are objects intermediate in mass between stars and planets and are natural byproducts of processes that primarily lead to the formation of stars and planets. The survey of dense star clusters where …

July 6, 2017Astronomers have detected a first-of-its kind compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the Big Bang. Finding such a galaxy early in the history of the universe challenges the current understanding of how massive galaxies form and evolve, the researchers said. The finding, published in the …

June 22, 2017China is set to launch a space telescope, the Hard X-ray Modulation Telescope (HXMT), to observe pulsars in the galaxy of Milky Way, according to scientists. "We are still not clear about the interior of pulsars," Zhang Shuangnan, lead scientist of HXMT and director of the Key Laboratory of Particle Astrophysics of the Chinese Academy …

June 3, 2017NASA's Hubble space telescope has detected a supermassive black hole that has been kicked out of the centre of a distant galaxy by what could be the awesome power of gravitational waves. Weighing more than one billion suns, the rogue black hole is the most massive black hole ever detected to have been kicked out …

March 24, 2017The Hubble space telescope has captured an image to showcase an incredible massive galaxy, UGC 12591, that lies just under 400 million light-years away from the Earth. The galaxy and its halo together contain several hundred billion times the mass of the Sun — four times the mass of the Milky Way, NASA said in …

March 4, 2017Examining a molecular cloud with enigmatic motion, a team led by researchers in Japan has found signs of stray black hole hiding in the Milky Way. It is difficult to find black holes, because they are completely black. In some cases black holes cause effects which can be seen. Theoretical studies have predicted that 100 …

February 3, 2017A supermassive black hole in the centre of the Milky Way galaxy flings out planet-sized 'spitballs' formed from fragments of stars shredded by it, scientists have found. Every few thousand years, an unlucky star wanders too close to the black hole whose powerful gravity rips the star apart, sending a long streamer of gas whipping …
