The 305-metre-wide radio telescope at Arecibo, Puerto Rico is permanently closing. Engineers cannot find a safe way to repair it after two cables supporting the structure suddenly and catastrophically broke, one in August and one in early November.

"Even attempts at stabilization or at testing the cables could result in accelerating the catastrophic failure," said Ralph Gaume, the NSF's head of astronomy, at a 19 November media briefing.

Today's lunar eclipse that begins at 17:45(UTC) and lasts until 21:04(UTC) will be a "penumbral eclipse," which occurs when the outer ring of Earth's shadow just grazes the moon.

This subtle lunar eclipse will be entirely visible for observers in eastern Africa, the Middle East, southern Asia and Australia. It will start at moonrise for those on the eastern coast of South America, western Africa and Europe, and at moonset for skywatchers in Japan and New Zealand.

The full moon in June is called a Strawberry Moon because it coincides with the strawberry harvest. In Europe, an old name for this full Moon is the Mead Moon or the Honey Moon.

Discovery of Rare Super-Earth at End of Galaxy

A discovery made by University of Canterbury astronomers shows a rare Super-Earth planet near the end of our galaxy. The planet was discovered using gravitational microlensing, a technique that detects planets regardless of the amount of light they emit. The planet's mass and orbit are both similar to that of Earth.
