Billions of celestial objects revealed in gargantuan survey of the Milky W
Updated : 3 years, 1 month ago IST
Astronomers have released a huge survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects, arguably the largest such catalogue so far. The data for this unprecedented survey was taken with the Dark Energy Camera, built by the US Depa

NASA's retired Compton mission reveals superheavy neutron stars
Updated : 3 years, 2 months ago IST
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the

Astronomers find the most distant stars in our galaxy halfway to Andromeda
Updated : 3 years, 2 months ago IST
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light-years from Earth, almost half the distance to our neighbouring galaxy, Andromeda, which is about 2.5 million

Astronomers discover clues about stellar 'glitching'
Updated : 3 years, 2 months ago IST
Astronomers have found a way to peer into the physics of some of the brightest stars in the sky. Using data from NASA's Kepler space telescope, an international team of researchers has found new evidence that red giants, dying stars that have exhausted their supply of hydrogen and are in the

Webb Space Telescope reveals previously shrouded newborn stars
Updated : 3 years, 2 months ago IST
Rice University astronomer Megan Reiter and colleagues took a "deep dive" into one of the first images from NASA's James Webb Space Telescope and were rewarded with the discovery of telltale signs from two dozen previously unseen young stars about 7,500 light years from Earth.

Webb telescope 'Pearls' project brings exquisite views of distant galaxies
Updated : 3 years, 2 months ago IST
For decades, the Hubble Space Telescope and ground-based telescopes have provided us with spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched in December 2021 and successfully completed commissioning during the first half of 2022. For astro

Astronomers find that two exoplanets may be mostly water
Updated : 3 years, 2 months ago IST
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planets

Researchers have measured the survival rate of antihelium nuclei from dept
Updated : 3 years, 2 months ago IST
How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including Technical University of Munich (TUM) scientists has now measured for

This tiny, hidden galaxy provides a peek into the past
Updated : 3 years, 3 months ago IST
Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years across, the tiny galaxy HIPASS J1131-31 has

Astronomers observe intra-group light, an elusive glow between distant gal
Updated : 3 years, 3 months ago IST
An international team of astronomers have turned a new technique onto a group of galaxies and the faint light between them known as 'intra-group light' to characterise the stars that dwell there.
