Many satellites of many other galaxies are actively pumping out new stars, but the Milky Way's satellites are mostly inert, the researchers found.
A team of astronomers has identified a young star, located almost 11,000 light years away. This star could help us understand how the most massive stars in the universe are formed. The star is
A huge region around the centre of the Milky Way galaxy is devoid of young stars, claims a new study. "The current results indicate that there has been no significant star formation in this large
London: One third of humanity cannot see the Milky Way at night due to the luminescent glow of artificial light, say scientists who created a new world atlas of light pollution. Artificial light pollutes the
Sydney: A team of international scientists has discovered hundreds of hidden galaxies hidden from view until now by our own galaxy, the Milky Way, some 250 million light years away from the Earth.The discovery may
New York: Contradicting current beliefs, a team of researchers, including one from India, has said that globular star clusters that hold a million stars in a ball only about 100 light-years across on average could
Sydney: Astronomers have discovered what they believe to be the oldest stars ever seen, dating from before the Milky Way Galaxy formed, when the universe was just 300 million years old.The nine stars, found near
Washington: There should at least be one billion Earth-sized worlds in the Milky Way galaxy at present, scientists have theorised, adding that in the entire universe, bulk of life-supporting planets -- 92 percent -- are
London: Photos taken by astronauts aboard the International Space Station (ISS) have helped scientists reliably measure the amount of light pollution worldwide.The study not only has the well-known signatures of cities and streets but also
New York: Nearly a third of the stars in our own galaxy have dramatically changed their obits, say scientists who have created a new map of the Milky Way."In our modern world, many people move
Washington: The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos, say NASA scientists.Neutrinos are tiny particles that carry no charge and interact very weakly with electrons
London, Mar 31: As many as 2,000 black holes kicked away from their homes are now living on the outskirts of our Milky Way galaxy, according to a new study.Researchers from the University of California,
