Unknown structure in galaxy revealed by high contrast imaging

As a result of achieving high imaging dynamic range, a team of astronomers in Japan has discovered for the first time a faint radio emission covering a giant galaxy with an energetic black hole at its center. The radio emission ...

Astronomy team finds evidence of galactic metal shrouded in dust

A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium—the space between stars—but dust can impede observations in optical wavelengths. ...

Astronomers detect a new radio source of unknown origin

During radio continuum observations of a spiral galaxy known as NGC 2082, Australian astronomers have discovered a mysterious bright and compact radio source, which received designation J054149.24–641813.7. The origin and ...

New ultra-faint dwarf galaxy discovered

Astronomers from the University of Arizona (UA) and elsewhere report the discovery of a new ultra-faint dwarf galaxy. The newfound galaxy, designated Tucana B, is the first quenched and isolated object of this type identified ...

Astronomers find 'gold standard' star in Milky Way

In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.
