Dark Sky Telescope Hire 20 Jul 2017, 15:05 UTC How big are stars? They range in size from giants hundreds of times the size of our sun to tiddlers much smaller than our sun. A team of astronomers at the University of Cambridge recently announced the discovery of the smallest star ever to be detected. EBLM J0555-57Ab is roughly 600 light-years away and is about the size of the planet Saturn. As a reference point you can fit about 1600 Saturns inside our Sun, so EBLM J0555-57Ab is really a very small star indeed.
collectSPACE.com: Space History News 20 Jul 2017, 12:20 UTC Forty-eight years ago, flight controllers in NASA's Houston Mission Control helped to guide Apollo 11 astronauts Neil Armstrong and Buzz Aldrin to the first ever landing on the moon. Just moments after Armstrong radioed to Earth the "Eagle has landed," Mission Control replied. "We copy you on the ground. You got a bunch of guys about to turn blue. (We're breathing again.)" Now, almost half a century later, some of those same guys are hoping you will help Mission Control raise some green.
Lights in the Dark 20 Jul 2017, 04:58 UTC Note: This is an updated article from 2012. Panorama of the Eagle lunar module by Ed Hengeveld from JSC scans. “That’s one small step for a man… one giant leap for mankind.” I’m not sure what else need be said about the significance of what happened on this day in 1969, 48 years ago… it was a shining moment in human history, and will be — should be — remembered forever as an example of what people can achieve when challenged, driven, and inspired. More giant leaps have been made since then, and undoubtedly more will be made in the future, but this was the first and to this date still very much the biggest. After Neil Armstrong stepped onto the Moon on the evening of July 20, 1969, LM pilot Edwin “Buzz” Aldrin followed. Below is a video of Buzz coming down the ladder—with a little direction from Neil. After he’s safely on the lunar surface Buzz famously comments on the “magnificent desolation” of the Moon. And here’s a video made from 16mm color film taken from the LM as Neil Armstrong prepared to collect lunar samples… look at the brown color of the soil! Also, you can briefly ...

Astronomy Now 19 Jul 2017, 22:57 UTC The MASCARA (Multi-site All-Sky CAmeRA) station at ESO’s La Silla Observatory in Chile has achieved first light. This new facility will seek out transiting exoplanets as they pass in front of their bright parent stars and create a catalogue of targets for future exoplanet characterisation observations.
The New York Times 19 Jul 2017, 20:00 UTC When the total solar eclipse traces a path on Aug. 21 from Oregon to South Carolina, millions will turn their gaze upward as the moon passes between the Earth and the sun, darkening the sky in the middle of the day. But what if they could see the eclipse from above instead?
