@janagrc As a child I loved "The Little House" & its message about the joys of observing nature. Then as an adult I noticed this.

Asteroid 2020 AV2 has gone where no other (known) asteroid has gone before: Past the dual gauntlet of Earth & Venus, settling in around the Sun entirely within Venus's orbit. https://t.co/8cDvCUdqJR

China's enormous FAST radio telescope--the largest single antenna in the world--has begun full scientific operations, after a highly productive three-year test run. https://t.co/WqdxS12j4f

The light in these images comes from quasars: disks of ultra-hot gas swirling around massive black holes at the centers of galaxies. You don't see the black hole, of course, just the material around it. https://t.co/HOCyDpS6Em

@UMDscience It's amazing how hard it is to understand turbulence, considering it is around us *everywhere*. https://t.co/lJR6xOUpL2

@aeonmag A century ago, nobody was sure whether other galaxies existed. Today, cosmologists debate how quickly the universe is expanding. Yet we still don't know how it will end, or really how it all began. https://t.co/h8CZF6aJcB

The "Radcliffe Wave" is a 9,000-light-year long ripple of stars and gas running through our part of the Milky Way. It stretches across half the sky, and we've never found anything like it before. https://t.co/bGzqkZGNnv

Pioneer 10 will pass about half a light year from the small orange star HIP 117795 in 90,000 years. All of our interstellar probes should survive at least a quintillion years before they crash into anything. https://t.co/BbD4Wft8ZR

The surface of #Betelgeuse is boiling (OK, convecting) at about 20 kilometers per second -- but it's so big that hot & cold spots on its surface stick around for years at a time. https://t.co/xCiybSOz3P

These are the largest, most detailed cosmic simulations ever created. Here, galaxies emerge from a mock universe that is 230 million light years wide, containing 20 billion particles. https://t.co/qZmpfDJ4DE via @maxplanckpress
