Hunting for the Faintest Galaxies
Astrobites reports on how we might find faint and distant dwarf galaxies without individually resolving their stars.

This remarkable photograph — which spans only ~10 µm across — reveals what happens when you form dust grains in a laboratory under conditions similar to those of interstellar space.
The habitability of distant exoplanets is dependent upon many factors — one of which is the activity of their host stars. A new study explores flares on Kepler stars.
What is the structure of the Milky Way’s disk, and how did it form? A new study uses giant stars to explore these questions.
Astrobites reports on a survey with the Spitzer Space Telescope to find distant exoplanets acting as tiny lenses.
What happens when the highly energetic jet from the center of an active galaxy rams into surrounding clouds of gas and dust?
The Sun plays an important role in protecting us from cosmic rays, energetic particles that pelt us from outside our solar system. But can we predict when and how it will provide the most protection?
Some distant active galaxies are louder in radio wavelengths than others. A new study explores whether this difference could be due to how quickly the supermassive black holes at their centers are spinning.
Astrobites reports on belts of dust discovered around our nearest neighbor, the star Proxima Centauri.
One of the challenges of astronomy is connecting theoretical models of distant objects to observations. A new code allows scientists to transform models of sources into images of what we’d expect to observe.
A hunt for merging dwarf galaxies has yielded an intriguing result: 180 million light-years away, a galaxy very similar to the Milky Way — with two dwarf-galaxy satellites just like our own Magellanic clouds.
How do the protoplanetary disks surrounding newly formed stars eventually disappear? Astrobites reports on the role that turbulence in the disks might play.
