I Zwicky 18 - One Of The Strangest Known Irregular Galaxies

The remnants of a supernova, which usually leaves behind a neutron star. However, no such x-rays have been discovered. Could this be the youngest black hole in the milky way?

The violent past of our galaxy’s black hole could help us solve a cosmic mystery

The supermassive black hole at the center of our galaxy is pretty quiet now, but new research suggests that 6 million years ago it was raging and gobbling up matter. Scientists think it could explain a mysterious disappearance.

Top: Hubble’s infrared vision pierced the dusty heart of our Milky Way galaxy to reveal more than half a million stars at its core. At the very hub of our galaxy, this star cluster surrounds the Milky Way’s central supermassive black hole, which is about 4 million times the mass of our sun.

Another Station Upgrade:

Spacewalkers Jeff Williams and Kate Rubins to install new TV cameras 

On Thursday, Sept. 1, U.S. astronauts Jeff Williams and Kate Rubins will conduct the station’s 195th American spacewalk. As part of their activities, the pair will install the first of several enhanced high-definition television cameras that will monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles

Working on the station’s backbone, or truss, Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system. 

As was the case for their first spacewalk together on Aug. 19, Williams will be designated as extravehicular crew member 1 (EV1), wearing a spacesuit with a red stripe, while Rubins will be EV2, wearing a suit with no stripes.

Watch LIVE!

Coverage of the spacewalk begins at 6:30 a.m. EDT on Thursday, Sept. 1; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

Philae found!

Less than a month before the end of the mission, Rosetta’s high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov–Gerasimenko.  The images were taken on 2 September by the OSIRIS narrow-angle camera as the orbiter came within 2.7 km of the surface and clearly show the main body of the lander, along with two of its three legs.  The images also provide proof of Philae’s orientation, making it clear why establishing communications was so difficult following its landing on 12 November 2014. Philae was last seen when it first touched down at Agilkia, bounced and then flew for another two hours before ending up at a location later named Abydos, on the comet’s smaller lobe.After three days, Philae’s primary battery was exhausted and the lander went into hibernation, only to wake up again and communicate briefly with Rosetta in June and July 2015 as the comet came closer to the Sun and more power was available.  The discovery comes less than a month before Rosetta descends to the comet’s surface. On 30 September, the orbiter will be sent on a final one-way mission to investigate the comet from close up, including the open pits in the Ma’at region, where it is hoped that critical observations will help to reveal secrets of the body’s interior structure.
