The moon has a new hole on its surface thanks to a boulder that slammed into it in March, creating the biggest explosion scientists have seen on the moon since they started monitoring it.
The meteorite crashed on March 17, slamming into the lunar surface at a mind-boggling 56,000 mph (90,000 kph) and creating a new crater 65 feet wide (20 meters). The crash sparked a bright flash of light that would have been visible to anyone looking at the moon at the time with the naked eye, NASA scientists say.
“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” Bill Cooke of NASA’s Meteoroid Environment Office said in a statement. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.” [The Greatest Lunar Crashes Ever]

The sun’s peak of solar activity this year will likely be the quietest seen in at least 100 years, say NASA scientists who watch Earth’s closest star daily.
Sunspot numbers are low, researchers said, even as the sun reaches the peak of its 11-year activity cycle. Also, radio waves that are known to indicate high solar activity have been very subdued.
“It’s likely to be the lowest solar maximum, as measured by sunspot ‘number,’ in more than a century,” wrote Joe Gurman, a project scientist for NASA’s sun-observing mission Stereo, or Solar TErrestrial RElations Observatory. The current sun weather cycle is known as Solar Cycle 24.
