Galaxy found to float in a tranquil sea of halo gas

Using one cosmic mystery to probe another, astronomers have analyzed the signal from a fast radio burst, an enigmatic blast of cosmic radio waves lasting less than a millisecond, to characterize the diffuse gas in the halo ...

The bright ways forests affect their environment

For decades scientists have tried to understand why forests emit the volatile gases that give pine forests their distinctive smell. A new study led by the University of Leeds may have found the answer.

Radio shadow reveals tenuous cosmic gas cloud

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered the most tenuous molecular gas ever observed. They detected the absorption of radio waves by gas clouds in front of bright radio sources. ...

Galaxy's snacking habits revealed

A team of Australian and Spanish astronomers have caught a greedy galaxy gobbling on its neighbours and leaving crumbs of evidence about its dietary past.

This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian 209. Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study ...

Distant quasar illuminates a filament of the cosmic web

Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing for the first time part of the network of filaments thought to connect galaxies in a cosmic web. Researchers at the University ...

Image: Hot gas sloshing in a galactic cauldron

(Phys.org) —Galaxies are social beasts that are mostly found in groups or clusters – large assemblies of galaxies that are permeated by even larger amounts of diffuse gas. With temperatures of 10 million degrees or more, ...
