About 12 weeks ago Breathtaking image of Messier 5 taken by Hubble
Description from the Hubble site: This sparkling jumble is Messier 5 — a globular cluster consisting of hundreds of thousands of stars bound together by their collective gravity. But Messier 5 is no normal globular cluster. At 13 billion years old it is incredibly old, dating back to close to the beginning of the Universe, which is some 13.8 billion years of age. It is also one of the biggest clusters known, and at only 24 500 light-years away, it is no wonder that Messier 5 is a popular site for astronomers to train their telescopes on. Messier 5 also presents a puzzle. Stars in globular clusters grow old and wise together. So Messier 5 should, by now, consist of old, low-mass red giants and other ancient stars. But it is actually teeming with young blue stars known as blue stragglers. These incongruous stars spring to life when stars collide, or rip material from one another.

About 8 weeks ago In 2014, May new moon falls on May 28
From EarthSky: Few, if any, people around the world can expect to see the moon before sunrise or after sunset on May 28, 2014. It is the day of the new moon, the day on which the moon crosses from the morning to the evening sky, and the sun and moon reside on the same side of Earth in space. Today, the moon pretty much rises with the sun at sunrise, crosses the sky with the sun during the daytime and sets with the sun at sunset.

About 6 weeks ago June 12-13's full moon - a Honey Moon
From EarthSky: In this hemisphere, the June full moon is sometimes called a Honey Moon, possibly because it never gets very high in the sky. When we gaze toward this full moon throughout the night tonight, we are seeing it through more of Earth’s atmosphere than when the moon is overhead. The atmosphere reddens its color. Slooh will be broadcasting online coverage of the full Honey Moon. More at: http://earthsky.org/Tonight Photo Credit: Bruce Fingerwood.
