These are the 27 newly-discovered supernova remnants. The MWA radio images trace the edges of the explosions as they continue their ongoing expansion into interstellar space. Some are huge, larger than the full Moon, and others are small and hard to spot in the complexity of the Milky Way. Image credit: Natasha Hurley-Walker, ICRAR & Curtin / GLEAM Team.

This composite image shows the Orion A molecular cloud, the nearest known massive star factory, as seen by ESA’s Herschel and Planck space observatories. Located approximately 1,630 light-years away, Orion A is one of the two giant molecular clouds in the Orion molecular cloud complex. The other cloud is Orion B, which lies east of Orion’s Belt. Orion A is packed full of gas -- it contains so much material, in fact, that it would be capable of producing tens of thousands of Sun-mass stars. Different colors visible here indicate the light emitted by interstellar dust grains mixed within the gas, as observed by Herschel at far-infrared and sub-millimeter wavelengths, while the texture of faint gray bands stretching across the frame, based on Planck’s measurements of the direction of the polarized light emitted by the dust, show the orientation of the magnetic field.

This mosaic of the southern sky was assembled from 208 TESS images. Among the many notable celestial objects visible is the glowing band (left) of the Milky Way, our home Galaxy seen edgewise, the Orion Nebula (top), a nursery for newborn stars, and the Large Magellanic Cloud (center), a nearby galaxy located about 163,000 light-years away. The prominent dark lines are gaps between the detectors in TESS’ camera system. Image credit: NASA / MIT / TESS / Ethan Kruse, USRA.

The moons of our Solar System are brimming with unusual landscapes. However, sometimes they look a little more familiar, as in this new radar image from the Cassini orbiter. The image shows dark streaks carved into dunes reminiscent of those we might find on a beach on Earth, or raked with flowing lines in a Japanese Zen garden — but this scene is actually taking place on Saturn’s moon Titan. While our sand is composed of silicates, the ‘sand’ of these alien dunes is formed from grains of organic materials about the same size as particles of our beach sand. The small size and smoothness of these grains means that the flowing lines carved into the dunes show up as dark to the human eye. While previous images have spotted these eerily familiar patterns on Titan's dunes, this new image (colorized) shows them in greater detail. The image was obtained by Cassini's radar mapper on July 10, 2013. The vertical seam near the center is an artifact of radar image data processing. Image credit: NASA / JPL-Caltech / Sci-News.com.
