Astronomers have discovered a bizarre new pulsar-like object that's throwing out regular bursts of radio waves every 44 minutes. Totally normal, long-period pulsar behavior. But observations from Chandra show that it's also releasing a blast of X-rays every 44 minutes as well. The astronomers also found that the amount of both radio waves and X-rays has been decreasing over the course of six months. Is this a totally new type of object?

Astronomers have observed Jupiter's moon Europa with JWST and discovered that its icy surface is constantly changing, crystallizing at different rates in different places. There are two broad types of ice, crystalline and amorphous, and the researchers found that these are mixed up together, especially in regions with cracks, ridges, and plains jumbled up. This suggests that water is bubbling up from the interior, pushed by geologic processes.

Linking again to this #ForbiddenPlanet fan project.

A lot of people have made 3D computer or physical models of the Enterprise from Star Trek, but this is the same sort of thing with the settings from Forbidden Planet.

Starting with a tour of the C57-D based on fan floorplans, I think:

Great ambient sound, too!

The Big Wheel galaxy has no business being that big that early in the age of the Universe. It's doing everything right, but our ideas of how galaxies form and grow may need some poking.
