An artist impression of HD 142527 based on ALMA data. According to astronomers, HD 142527 consists of a main star a little more than twice the mass of our Sun and a smaller companion star only about a third the mass of our Sun; they are separated by approximately one billion miles. The rendition shows a distinctive arc of dust (red) embedded in the protoplanetary disk. The red arc is free of gas, suggesting the carbon monoxide has frozen out, forming a layer of frost on the dust grains in that region. Astronomers speculate this frost provides a boost to planet formation. The two dots in the center represent the two stars in the system. Image credit: B. Saxton / NRAO / AUI / NSF.

This artist’s concept shows an active supermassive black hole with a jet streaming outward at nearly the speed of light. Such black holes are often found at the hearts of elliptical galaxies. Not all black holes have jets, but when they do, the jets can be pointed in any direction. If a jet happens to shine at Earth, the object is called a blazar. Image credit: NASA / JPL-Caltech.

This composite image shows the size and location of the Smith Cloud on the sky. The cloud is 15 degrees across in angular size - the width of an outstretched hand at arm’s length. The apparent size of the full Moon is added for comparison. The Smith Cloud appears in false-color, radio wavelengths. The visible-light image of the background star field shows the cloud’s location in the direction of the summer constellation Aquila. Image credit: NASA / ESA / Z. Levay, STScI / B. Saxton / F.
