When you have a $446 million spacecraft funded by public money, there is a considerable amount of pressure to squeeze it for every last drop of science. The Dawn mission has already made spectacularly successful visits to two asteroids, Vesta and Ceres. It is now orbiting around Ceres, having completed a “final” Low-Altitude Mapping Orbit.
This week’s lunar eclipse was seen by by thousands of people, but simultaneously there was an eclipse that was much harder to see. Had we been standing on the surface of the Moon, we would have seen the Sun silently glide behind the black Earth, leaving only a broken, fiery ring – all the sunrises

Notice the downward facing lights along the wall. The lamp in the parking lot is extremely bright, but faces downward. The interior
In 2002, a previously unknown star in the constellation Monoceros, The Unicorn, briefly became the brightest star in our galaxy. Although great debate rages about the reasons for V838 Mon’s flareup, there is general consensus that images taken by the Hubble Space Telescope in the months and years afterward are some of the most
