Drilling Holes on the Red Planet

This image shows the Highfield drill hole, on Vera Rubin Ridge in Gale crater on Mars, made by NASA’s Curiosity rover in its search for rock samples. Just recently, scientists announced that an analysis of rock samples collected by the rover were enriched in carbon 12, a type of carbon that on Earth is associated with biological processes. via NASA https://ift.tt/3qCin1n

From Orion to the Southern Cross

This is a sky filled with glowing icons. On the far left is the familiar constellation of Orion, divided by its iconic three-aligned belt stars and featuring the famous Orion Nebula, both partly encircled by Barnard’s Loop. Just left of center in the featured image is the brightest star in the night: Sirius. Arching across the image center is the central band of our Milky Way Galaxy. On the far right, near the top, are the two brightest satellite galaxies of the Milky Way: the Large Magellanic Cloud (LMC), and the Small Magellanic Cloud (SMC). Also on the far right — just above the cloudy horizon — is the constellation of Crux, complete with the four stars that make the iconic Southern Cross. The featured image is a composite of 18 consecutive exposures taken by the same camera and from the same location in eastern Australia during the last days of last year. In the foreground, picturesque basalt columns of the Bombo Quarry part to reveal the vast Pacific Ocean. via NASA https://ift.tt/3rlybEU
