Our fourth and fifth astronomical gifts are … Stephan’s Quintet!
When looking at this image from @NASAWebb, Stephan’s Quintet seems like five galaxies hanging around each other — but did you know that one of them is much closer than the others? go.nasa.gov/3hoan2p
#NASAUniverse


Four of the galaxies are hanging out together about 290 million light-years away, but the fifth and leftmost galaxy in the image below is actually closer to Earth at just 40 million light-years away! Here’s a labeled view from @chandraxray and a ground-based optical telescope.

These colorful shreds of cosmic material are the "leftovers" of a massive star's supernova explosion!

Welcome to #Artemis, Rwanda and Nigeria. 🇷🇼 🇳🇬

By signing the Artemis Accords, these two nations have joined over 20 others in the commitment to the peaceful and safe exploration of space. go.nasa.gov/3Yit881
#NASAArtemis #Artemis

in reply to NASA

Glad 2 know #NASA 's peaceful efforts affecting #Human #OuterSpace cooperation, growth & prosperity, as in our current context of wars between nations, the fragility of cooperative interests is precarious, & these accords will, over the next 500 yrs, limit the oppressive nature of colonialistic expansion into outer space vs peaceful partnerships! Let just relations b our guiding principles!

Gene: Nice view, huh?
Jack: The horizon’s ok. Not very colorful, though.
Gene: D’you wanna listen to some tunes?
Jack: Sure. Whatcha got?
Gene: uh, let’s see, Bowie-Major Tom, Floyd-Eclipse, and Elton-Rocket Man.
Jack: hmmm. No CCR-Bad Moon Rising?
Gene: Oh shit, I missed a turn.
Jack: Haha. Good thing your wife isn’t here to get on you about that, right?
Gene: Amen, brother. It’s nice to get out with just the dudes.

#OTD in 1993, the first servicing mission by astronauts to Hubble came to a close!

This mission fixed Hubble's optics, following the discovery of an error in its primary mirror, which was ground too flat by less than the width of a single human hair!

New scientific instruments were also installed during this mission, which was followed by four more servicing missions using the space shuttle.

Alaska has nearly 1 million miles of rivers, but only 10% of them are gauged, or measured.

By #TrackingWorldWater, SWOT will measure the height of surface water from space and help groups like the Alaska Department of Fish and Game better manage salmon spawning and survival.
#NASAEarth

in reply to NASA

There is misleading. Presumably this means that ~10 percent of rivers have one or more gauges, not that >100,000 "miles of river" are gauged.


SWOT will allow us to see Alaska’s waters in ways we haven’t before, which is important, because Alaska, being in the Arctic, is also where the U.S. is experiencing the most climate change right now.

We (myself included) have taken this for granted for 50 years. But … Damn, we built rockets, spaceships, protective suits, & all the comm/control systems to make it work, … and then sent people to the MOON! And back!
And we did all that with the primitive computing capabilities available back then … 🤦‍♂️

When two galaxies encounter each other, it takes 1-2 billion years for them to merge and settle down. While the stars already in the galaxies don’t change much, the collision can spark lots of new stars to form! ✨ #MondayMotivation
