This is real: Astronomers have zoomed in on the supermassive black hole in galaxy M87, revealing both the shadow of the event horizon & jets of hot plasma shooting outward.

The UAE's Hope Mars orbiter got an extremely rare close look at the planet's enigmatic outer moon, Deimos. https://www.nature.com/articles/d41586-023-01422-1

I know everyone likes to joke about Uranus, but in this image the outer moon of Mars looks a bit like the, er, backside of a human. https://www.nature.com/articles/d41586-023-01422-1

@rich We've seen that small solar system bodies can look like potatoes, diamonds, rubber ducks, ravioli, and...butts.

Takeshi Hakamada, the CEO of @ispace_inc, is looking ahead to the company's next two Moon missions. Bottom line, it's really hard to land on a large, airless world. Closing quote from the livecast: "Never quit the lunar quest."

"We have to assume...that we could not complete the landing on the lunar surface." Sad news from the @ispace_inc team about the HAKUTO-R lander.

We are moments away from the first successful private landing on the Moon.

This is a nail-biting moment. If HAKUTO-R is successful, it will be the first time a private organization has landed on the Moon -- a pivotal moment in space history. https://www.nature.com/articles/d41586-023-01423-0

Four years ago, Israeli company SpaceIL attempted a private landing on the Moon. The mission nearly succeeded, but crashed into the lunar surface seconds after taking this image. https://www.planetary.org/articles/beresheet-comes-close-crashes

During its 51st flight on Mars, NASA's Ingenuity helicopter spotted its shadow, indicating at least 6 more weeks of winter on the Red Planet.

Look carefully at the panorama taken by the Mars Ingenuity helicopter and you'll notice an alien presence in the distance: NASA's Perseverance rover, exploring a region called Echo Creek. https://mars.nasa.gov/mars2020/mission/status/461/up-and-soon-away-perseverance-continues-exploring-the-upper-fan/

@noplasticshower Perseverance is powered by a nuclear heat source (a radiothermal generator) and doesn't use solar panels.

Even if it were a solar-powered rover, though, getting close enough to blow dust off the rover would be a delicate maneuver, with a high risk of damage to both the rover & the helicopter.

@coreyspowell@mastodon.social avatar

@noplasticshower I expect there is an engineering way to make it work, but the cost/benefit tradeoff could be tough. That's why the InSight mission was intentionally designed to end when its panels got dusty.

Aurora photos are pouring in now, from locations as far south as Kentucky in the U.S.

@dendroica @scenario I'm in Brooklyn. Between clouds & intense light pollution, I couldn't see anything. The photos are amazing, though...

I still don't have a good idea of just how big is.

So I made this!

It's Starship and an @airbus A380, the largest commercial aircraft in service, to scale.

Good news for people who like their world well-ordered: A team of astronomers has concluded that all the planetary systems across our galaxy appear to fall into just four basic types. https://www.unibe.ch/news/media_news/media_relations_e/media_releases/2023/media_releases_2023/four_classes_of_planetary_systems/index_eng.html

Waiting for someone to apply this to the universe.

How space people see this Starship explosion (impressed it got off the pad, interested to see how design changes now) is wildly different from how everyone else sees it (wow, huge failure, bad that a rocket exploded)
