Astronomy picture of the day - 2018 March 27 - Mars Between Nebulas
Image Credit & Copyright: Sebastian Voltmer
Explanation: What that bright red spot between the Lagoon and Trifid Nebulas? Mars. This gorgeous color deep-sky photograph captured the red planet passing between the two notable nebulas -- cataloged by the 18th century cosmic registrar Charles Messier as M8 and M20. M20 (upper right of center), the Trifid Nebula, presents a striking contrast in red/blue colors and dark dust lanes. Across the bottom right is the expansive, alluring red glow of M8, the Lagoon Nebula. Both nebulae are a few thousand light-years distant. By comparison, temporarily situated between them both, is the dominant "local" celestial beacon Mars. Taken last week, the red planet was only about 10 light-minutes away.

Astronomy picture of the day - 2018 March 26 - The Coma Cluster of Galaxies

Explanation: Almost every object in the above photograph is a galaxy. The Coma Cluster of Galaxies pictured here is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies houses billions of stars - just as our own Milky Way Galaxy does. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other. Most galaxies in Coma and other clusters are ellipticals, while most galaxies outside of clusters are spirals. The nature of Coma's X-ray emission is still being investigated.

Brassaï - A noite parisiense - Fotografia
Um dos fotógrafos mais célebres de seu tempo, Brassaï registrou Paris de forma irreverente. A noite parisiense exerceu um enorme fascínio sobre ele, que não cansou de fotografá-la.
