A global team of radio astronomers have on Thursday unveiled the first image of the supermassive black hole at the centre of the Milky Way galaxy.
Previously such small, "stellar-mass" black holes have been spotted in other galaxies by picking up the X-ray glow emitted as they swallow matter, or from the gravitational waves generated as black holes collide with one another or with neutron stars.
Globular cluster is older than 10 billion years, like most other globular clusters, meaning that it formed in the earliest phases of galaxy formation. It is about 10 times less massive and five times more extended than a typical globular cluster and in the final stages of dissolution.
Washington: NASA’s Hubble Space Telescope has spotted a brilliant “celebrity star,” one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust and…
Nainital (Uttarakhand): Scientists at the Aryabhatta Research Institute of Observational Sciences (ARIES) here have discovered 28 new variable stars in the Milky Way galaxy. ARIES Director Wahab Uddin described the finding of the new variable stars, whose luminosity or brightness keeps changing, as a “rare achievement”. It is for the first time that variable stars […]
Washington: In yet another interstellar feat, scientists at the LIGO detectors and the world over detected the first “ripples in space” or gravitational waves produced by the merger of two ancient remnants of stars known as neutron stars. The neutron stars merged in a galaxy called NGC 4993, located about 130 million light years from Earth […]
New York: Our 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 […]
Our Milky Way galaxy may have formed from the inside-out, according to a ground-breaking study which provides new insight into galactic evolution
