BREAKING: As Donald Trump cancels free admission to National Parks on MLK Day, California will be offering FREE entry at more than 200 participating state parks. Honor MLK. Get outdoors. And stick it to an old man with a fragile ego.

Here’s a little ghostly glitter for the weekend 👻 You’re looking at a star-forming cloud called Lupus 3, which lives 500 light-years away in the constellation Scorpius. Learn more about this image by Hubble: go.nasa.gov/3NroCTK

Hubble studied these luminous protostars to learn how massive stars form. Protostars are shrouded in thick dust, but Hubble can detect the near-infrared emission that shines through holes made by the protostars' jets of gas + dust: go.nasa.gov/49vNIbi

"I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war." Watch Martin Luther King Jr.'s Nobel Peace Prize speech, where he accepted the award on behalf of the American civil rights movement: bit.ly/3bJCQuc #MLKDay

This seemingly serene landscape of gas and dust is hopping with star formation behind the scenes! Lupus 3 is a star-forming cloud about 500 light-years away in the constellation Scorpius. Read more about this Hubble image HERE >> go.nasa.gov/4qnf6zA

Galactic upcycling ♻️ Webb captured a new close-up of an old favorite, the Helix Nebula. We’ve seen this region before with telescopes like Hubble and the retired Spitzer Space Telescope, but Webb zooms into this dying star with a deeper, more detailed view.

They're more than "The Rings of Power"! 🧙‍♂️💍 The ALMA Kuiper Belt Substructure Resolver survey has produced the sharpest images to date of 24 debris disks—the dust belts left behind after planet formation. almaobservatory.org/en/audiences/a…

Are you HH 80/81? Because you're exceptionally bright 😎 These glowing patches, named HH 80/81, are caused by colliding jets of stellar gas and are the brightest of their kind known to exist. go.nasa.gov/460IOCh

A green and red aurora streams across Earth’s horizon above the city lights of Europe in this photo taken from the International Space Station on Jan. 19. These auroras are caused when energetic particles from space collide with atoms and molecules in our atmosphere. 📸: NASA/Chris Williams

Beware of any Christian movement that demands the government be an instrument of God's wrath but never a source of God's charity, mercy, or compassion.

I’m incredibly lucky to have the opportunity to share the universe with you all. Thanks for joining me on this nonstop hype train for all things space! I have a few really exciting projects I’m working on that I hope will blow your mind!

Today is the 40th anniversary of the Challenger disaster. As we prepare for our Artemis missions to and around the Moon, it's important that we honor members of the NASA family who lost their lives while furthering the cause of exploration and discovery.

What a beautiful halftime performance by an all-American superstar, Bad Bunny. Together we are America. 🇺🇸🇺🇸🇺🇸

Unpopular opinion but true: Public health and modern agriculture exist for the same reason. To reduce human suffering.

RFK Jr. is now blocking an updated flu vaccine for no reason grounded in science. American vaccine policy has been hijacked by a conspiracy theorist—yet most Republicans are happy to just sit on their hands. They are allowing FDA policy to be dictated by DELUSION.

It’s time to stop calling it misinformation and call it what it really is: propaganda designed to destabilize confidence in evidence-based decision-making. The tactic isn’t to win the argument - it is to make the public doubt whether arguments can be settled by evidence at all.

Trump and his Administration want to make an example out of me so they can scare Americans like you and keep you from speaking out against him. The most patriotic thing any of us can do right now is to keep speaking up.

All chemicals, natural or synthetic, can be hazardous at some dose. The key scientific question is not whether a hazard exists, but whether people are exposed to levels that can cause harm.

At some point, even the anti-vaxxers are going to realize that this is bad for the economy

The International Space Station rarely makes big changes to its orientation, but we were lucky to experience such maneuvers (flipping around to fly butt-first, then flipping back again) before and after each @spacex CRS-33 reboost. This 60x speed timelapse was one of my favorites since it
