Same video as before of ATLAS observing the DART impact, but tracked sidereally (with the stars). Each frame is about 40 seconds, and the entire sequence is about two hours.

Microgravity provides a unique look at fluids like water, and we’re taking advantage of that in @Space_Station research! Scientists use surface tension to gain a new perspective on diseases and examine small forces that control liquids. #WorldWaterDay

The holes in honeycombs don't actually start out as hexagons. Bees create circular tubes staggered with one another. The heat formed by the activity of the bees softens the wax. Then the wax hardens into the the most energy efficient shape, the hexagon buff.ly/35ETQgI

It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong. In that simple statement is the key to science.

Q: What do you do?
A: I'm a geologist.
Q: So, you just look at rocks all day?
A: Actually, no! Geology is much more than field work. It's also GIS mapping, writing, analyzing satellite images, studying rock slices under the microscope, & flying in helicopters. #GeologistsDay 1/3

#DidYouKnow?
A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. 🤓 Cr: @NASA

Giraffes have a blue tongue to protect them from sunburn, because they graze on the tops of trees for up to 12 hours a day in the direct sunlight. Their tongue contains melanin, the same pigment responsible for tanning [read more: buff.ly/2I25biB]

On November 12, 1833, there was a meteor shower so intense that it was possible to see up to 100,000 meteors crossing the sky every hour. At the time, many thought it was the end of the world. This woodcut by Adolf Vollmy was inspired by the event [more: buff.ly/3d5XQKo]
