Wormholes

My name is Emily. I post a lot of science, nature, art, and other stuff that interests me on here.

This is a side blog of mine. I run a main blog that I post personal stuff on. You can get the link below.

itsfullofstars: Farthest Untethered Spacewalk Mission Specialist Bruce McCandless II, is seen further away from the confines and safety of his ship than any previous astronaut has ever been. This space first was made possible by the Manned Manuevering Unit or MMU, a nitrogen jet propelled backpack. After a series of test maneuvers inside and above Challenger’s payload bay, McCandless went “free-flying” to a distance of 320 feet away from the Orbiter. This stunning orbital panorama view shows McCandless out there amongst the black and blue of Earth and space. 12 February 1984

rhamphotheca: Bode’s Galaxy (NGC 3031 or M81): The black hole at the center of this galaxy is estimated to have consumed over 70 million stars the size of our sun. It is 15 times the mass of the black hole at the center of the Milky Way. (via: Journal of Cosmology)    (photo: NASA/JPL-CalTech)
ssaxs: Active Black Hole Squashes Star Formation New data from the Herschel Space Observatory shows that galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less ones. Supermassive black holes are believed to reside in the hearts of all large galaxies. When gas falls upon these monsters, the materials are accelerated and heated around the black hole, releasing great torrents of energy. In the process, active black holes often generate colossal jets that blast out twin streams of heated matter. Inflows of gas into a galaxy also fuel the formation of new stars. In a new study of distant galaxies, Herschel helped show that star formation and black hole activity increase together, but only up to a point. Astronomers think that if an active black hole flares up too much, it starts spewing radiation that prevents raw material from coalescing into new stars. This artist concept of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results. The bright core of the galaxy, paired with an overlaid artist’s impression of jets emanating from it, indicate that the central black hole’s activity is intensifying. As the active black hole continues to rev up, the rate of star formation will, in turn, be suppressed in the galaxy. Astronomers want to further study how star formation and black hole activity are intertwined.
