As we remember actor Leonard Nimoy today, we wanted to share this from our Museum of American History’s collection. They’re ear tips Nimoy wore as Mr. Spock in the 1982 movie “Star Trek: The Wrath of Khan.” The authentication card is signed in green ink by Leonard Nimoy.

Okay, I knocked this out in a couple of hours after the internet shenanigans of last night. If I had posted this five minutes later, it wouldn’t be funny anymore because everyone would have already forgotten about The Dress thingy. So, here’s an adaptation of H.P. Lovecraft’s “The Colour Out of Space” from the September, 1927 issue of Amazing Stories.  

A globular cluster of stars known as Palomar 12.

Although it currently resides on the outskirts of the Milky Way’s halo, Palomar 12 was not born here. When astronomers first studied this cluster, they were puzzled by its strangely young age when compared to the other clusters within the galaxy. It appeared to be around 30 percent younger than other Milky Way globulars.

It was revealed that Palomar 12 was actually ripped from its initial home, the Sagittarius Dwarf Elliptical galaxy, around 1.7 billion years ago via tidal interactions between its former home and our galaxy. The dwarf galaxy that Palomar 12 once called home is a satellite galaxy to ours, and closely orbits around us — even occasionally passing through the plane of our galaxy. In fact, it is being slowly torn apart and consumed by the Milky Way.
