For as long as humans have watched the night sky, we have wondered about the moon, pondering everything from its alien appearance to its influence over phenomena on Earth such as ocean tides, climate stability, and even the natural rhythms of many organisms. Among the many questions we have about Earth’s lone natural satellite, one remains preeminent: what are the moon’s origins, and how long has it orbited Earth?

Read MoreAstronomers want your help finding ‘missing’ black holes in the Milky Way
Astronomers estimate that our home galaxy, the Milky Way, has churned out more than 10 million black holes over its 13-billion-year history. Yet so far, they have found only 70. Now, a group of astronomers in the U.K. is trying to close that vast gap by enlisting the public. Their project, called Black Hole Hunters, is looking for volunteers with a computer and a few spare minutes to sift through troves of data gathered by a NASA space telescope. By flagging recognizable patterns that could point to a “missing” black…
Read More10 best places to see the 2027 total solar eclipse in Spain
Spain is one of the easiest places in the world to experience the total solar eclipse on Aug. 2, 2027.

Excellent roads, plentiful accommodation and Málaga’s international airport make this an obvious alternative to North Africa and the Middle East. However, choosing where to watch requires some thought. Southern Spain’s…
