An international team of space scientists has found that observation of a gas cloud stream heading into a massive galaxy may offer evidence of gas material recycling. In their paper published in the journal Science, the group ...
Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new quiescent galaxy. The galaxy, designated JADES-GS+53.15508-27.80178, was found at a high redshift and has a relatively ...

At the center of galaxies, like our own Milky Way, lie massive black holes surrounded by spinning gas. Some shine brightly, with a continuous supply of fuel, while others go dormant for millions of years, only to reawaken ...

Using the Keck I telescope, Japanese astronomers have identified a massive quiescent galaxy in a distant galaxy protocluster known as SSA22. The galaxy, designated ADF22-QG1, turns out to be the most distant quiescent galaxy ...
To come into being, galaxies need a steady diet of cold gases to undergo gravitational collapse. The larger the galaxy, the more cold gas it needs to coalesce and to grow.
