A meteorite found in the Sahara Desert last year – specifically Adrar, Algeria – was actually part of a protoplanet (a rocky body in the process of forming into a planet) in our solar system and dates back before Earth was even formed. The piece of volcanic rock, which has been named Erg Chech 002 (or EC 002), is more than a million years older than the previous-oldest meteorite ever found. According to the Lunar and Planetary Institute, the fragments of EC 002 were “relatively coarse grained, tan and beige” with some crystals that were “larger green, yellow-green and less commonly yellow-brown”. It is composed of a rock called andesite that is pretty much only found in subduction zones here on Earth (locations where tectonic plates collided with each other that resulted with one of them going underneath the other). Interestingly, meteorites very rarely contain andesite and are mostly created by a different volcanic rock called basalt. Detailed analysis of the ....
315 Messier 106 is a spiral galaxy lying 22 million light-years from Earth in the constellation Canes Venatici. It is a Seyfert galaxy with an active nucleus emitting radio waves and X-rays due to presence of a supermassive black hole actively consuming matter within its core. Violent churning of spiral arms, dust clouds, and sprays of ionized hydrogen can be seen revolving around the nucleus. The the irregular galaxy to its lower left is UGC7356 which lies at a similar distance and the edge on spiral galaxy to its lower right is NGC 4248 which lies 24 million light-years away. Other faint, distant galaxies can be seen scattered around the image. ....
