This image from ESO's New Technology Telescope at the La Silla Observatory in Chile shows the Herbig-Haro object HH as jets emerging from a star-forming dark cloud. This object was the target of a study using ALMA during the Early Science phase.
Visible as a small, sparkling hook in the dark sky, this beautiful object is known as or for short. It is a starburst galaxy, so named because of the incredibly (and unusually) high rate of star formation occurring within it.
The Eridanus Void. This area shows almost no signs of cosmic matter, meaning no stars, planets, solar systems or clouds of cosmic dust. Researchers couldn't even find dark matter, which is invisible but measurable by its gravitational pull or black holes.
The Helix Nebula (The Eye of God or is a large planetary nebula 700 light years away in Aquarius. The glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.
The Iris Nebula, NGC lies light-years away in the constellation Cepheus. Atoms floating in the interstellar medium, including carbon and silicon, combine into tiny particles about the dimension of a visible light wave, causing scattering of light.
