The large dark feature is a classic Martian sand dune. Most sand on Earth is made from the mineral quartz, which is white and bright.
On Mars, most sand is composed of dark basalt, a volcanic rock. For this reason, dunes on Mars are darker than those on Earth.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) suggest that early Mars may have been warmed intermittently
by a powerful greenhouse effect. In a paper published in Geophysical Research Letters, researchers found that interactions between methane, carbon dioxide
and hydrogen in the early Martian atmosphere may have created warm periods when the planet could support liquid water on the surface.

NuSTAR Finds New Clues to 'Chameleon Supernova'
https://www.nasa.gov/feature/jpl/nustar-finds-new-clues-to-chameleon-supernova

One supernova in particular is challenging astronomers' models of how exploding stars distribute their elements. The supernova SN 2014C dramatically changed
in appearance over the course of a year, apparently because it had thrown off a lot of material late in its life. This doesn't fit into any recognized category of
how a stellar explosion should happen. To explain it, scientists must reconsider established ideas about how massive stars live out their lives before exploding.

"This 'chameleon supernova' may represent a new mechanism of how massive stars deliver elements created in their cores to the rest of the universe," said Raffaella
Margutti, assistant professor of physics and astronomy at Northwestern University in Evanston, Illinois. Margutti led a study about supernova SN 2014C published
this week in The Astrophysical Journal.

Gaia turns its eyes to asteroid hunting
https://phys.org/news/2017-01-gaia-eyes-asteroid.html

While best known for its surveys of the stars and mapping the Milky Way in three dimensions, ESA's Gaia has many more strings to its bow.
Among them, its contribution to our understanding of the asteroids that litter the solar system. Now, for the first time, Gaia is not only
providing information crucial to understanding known asteroids, it has also started to look for new ones, previously unknown to astronomers.

Astronomers uncover properties of a molecular outflow feature in a nearby starburst galaxy
https://phys.org/news/2017-01-astronomers-uncover-properties-molecular-outflow.html

An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy in Germany has revealed
essential properties of a molecular outflow feature in the nearby starburst galaxy designated NGC253. The findings were presented
in a paper published Jan. 18 on the arXiv pre-print repository.
