In a first, Indian Institute of Astrophysics astronomers spot ultraviolet emissions from novae in Andromeda galaxy

The Hindu  

Astronomers from the Indian Institute of Astrophysics have spotted far ultra violet emissions from novae for the first time in the neighbouring Andromeda galaxy. The ultraviolet emissions from novae are a special class of transient astronomical event that causes the sudden appearance of a bright, apparently new star that slowly fades over weeks or months, during their outburst. The IIA …

Our home galaxy, the Milky Way, is known for its famous, sparkly, spiral. An international team of researchers wanted to know: why are spiral galaxies like our very own Milky Way missing from the Supergalactic Plane? “Further, the simulation shows that our standard model of the Universe, based on the idea that most of its mass is cold dark matter, …

Among the many cosmic rays of the universe that pass through the Earth unseen, scientists have spotted astrophysical neutrinos that emanate from a nearby galaxy. Observed by an international team of scientists for the first time, the neutrinos were detected by the one billion ton IceCube Neutrino Observatory, that is situated 1.5-2.5 kilometres below the surface at the South Pole. …

CNN — Supermassive black holes act as the engines powering the centers of galaxies, including our own Milky Way galaxy. But in a first, scientists have observed that one galaxy contains three supermassive black holes at its core and they’re surprisingly close together. “Through our observations with extremely high spatial resolution we were able to show that the interacting galaxy …

ABC  

Astronomers have come up with one of the most accurate measurements of the galaxy's mass yet — and as it turns out, it's "on the beefier side". Key points: The mass comes in on the heavier end of previous estimates, which put it somewhere between 500 billion and 3 trillion times the weight of Earth's Sun Astronomers found only a …

Hubble finds dwarf galaxy in our cosmic neighbourhood

India TV News  

Using the Hubble Space Telescope, astronomers have discovered a dwarf galaxy in a globular cluster which is only 30 million light-years away. The team used the NASA/ESA telescope to study white dwarf stars within the globular cluster NGC 6752. The newly discovered cosmic neighbour, nicknamed Bedin 1 by the astronomers, is a modestly sized, elongated galaxy, the study said. Dwarf …
