What's in the sky tonight?
July 7, 2014

-Now the waxing gibbous Moon shines closely under Saturn in the evening (for North America), as shown at right. For southern South America, the Moon occults Saturn. Timetables: http://www.lunar-occultations.com/io...0708saturn.htm

-Another outbreak of noctilucent clouds is underway over Europe. Jim Henderson sends this picture from Torphins, 15 miles west of Aberdeen, Scotland. "This is the second time this summer we've seen extensive NLCs in Scotland," he says. "I took the picture using a Nikon D700 (f5.6) set at at ISO 500 for 3 seconds."

High-latitude sky watchers, take note of those settings. July is the best month of the year for noctilucent clouds, and your chance to take a similar picture could be just hours away.

Most galaxies contain one supermassive black hole -- why does this galaxy have three? The likely reason is that galaxy J1502+1115 is the product of the recent coalescence of three smaller galaxies. The two closest black holes are shown above resolved in radio waves by large coordinated array of antennas spread out over Europe, Asia, and Africa. These two supermassive black holes imaged are separated by about 500 light years and each has a likely mass about 100 million times the mass of our Sun. Currently, J1502+1115, at a redshift of 0.39, is one of only a few triple black hole system known and is being studied to learn more about galaxy and supermassive black hole interaction rates during the middle ages of our universe. Gravitational radiation emitted by such massive black hole systems may be detectable by future observatories.
