“Not for rinsing or washing,” they said. (Seen at Union Station.)

This fall, most Advanced Camera for Surveys and Wide Field Camera 3 imaging by Hubble will default to guide on a single star instead of two. Extensive testing confirms there is no perceptible impact on image quality. This helps keep Hubble productive well into the 2030s: https://bit.ly/49lTRYm

Artemis II Earthset: a sequence of 90 images captured with the Nikon Z9 #Artemis 🧪🔭

We have an *extremely* important announcement to make. From Wednesday, we will be launching our puffin live cam, coming to you from the Farne Islands. So you can watch puffins all day long. In celebration, please enjoy this clip of puffins being really busy for 39 seconds straight.

Got one

A rock got stuck on Curiosity’s drill, which allowed it to pick the rock up like some kind of sci-if trash picker and reveal the dirt underneath. (Sadly, no bugs.) The good news is the team has now managed to shake the stowaway stone off, which means the rover’s wacky adventures can continue…

The Nancy Grace Roman Space Telescope team now is targeting as soon as early September 2026 for launch, ahead of the agency’s commitment to flight no later than May 2027. By the end of its five-year primary mission, Roman is expected to amass a 20,000-terabyte data archive. #NASARoman

The beauty of squid against the waves

WOW! Ridiculous and entirely unexpected mammatus display just after sunset here in SE OK thanks to a severe thunderstorm literally over 100 miles away. I sadly didn't have my actual camera on me. #okwx

EVERYONE, WISH THE BBIES WELL ON THEIR HATCHING!!! aAAAAA it's finally happening!!

Sometimesin the intertidal, the only evidence of clams will be their siphons poking out of the substrate like snorkels. Fortunately they often can still be identified by their siphons, which can be fused or separate depending on species ecology.wa.gov/blog/july-20... (336)

Well, isn’t this a sight for sore eyes! 😍 Our beloved Hubble appears in this amazing image from one of Vantor's WorldView Legion satellites. It was 36 years ago today that Hubble was launched in the bay of the Space Shuttle Discovery from NASA’s Kennedy Space Center. Credit: Vantor.

From NASA: One week in the solar system 🌔 Even as Artemis II was making its historic trip to the Moon, several other NASA missions were exploring all across the solar system. Here are just a few of the images that some of them captured during the course of a few days in April 2026.

With this online interactive from NASA, users can type in a name and see it spelled out in Earth features found in Landsat images. We wanted to play along. 😁 Can you see STScI? Use the tool to spell your favorite space object and share it with us: https://go.nasa.gov/3QIxKF7

This rather creepy photo is Artemis II’s heat shield underwater, as taken by the U.S. Navy. This is the first photo we have of the heat shield, and upon initial examination it doesn’t seem to have the char loss that Artemis I’s had.

Nearly half a century and 16 billion miles later... From NASA: To conserve power, engineers at JPL have turned off an instrument on Voyager 1 – but the science continues! science.nasa.gov/blogs/voyager/

🧵1/5 Ever get that weirdly satisfying feeling when something finally goes way past its original plan? Well, #NewHorizons just did exactly that. After 20+ years since launch, it's now farther from Pluto than it was back in 2006. Really wild when you think about it.🔭 🧪 ⚛️ #Space

Hubble marks its 36th anniversary with a shimmering close-up of star-formation in the Trifid Nebula! Tiny, actively forming stars are eating and spewing material all around. (One at top left in brown, and two fiery red jets.) Explore it all: https://news.stsci.edu/4cvi5jL

i don’t get this post. is it supposed to be funny

My mom - a geologist - gets out the embroidery that I made her every spring. Because trilobites wearing a crown of flowers are a harbinger of springtime. #Embroidery

Captured on this day, April 17, 2009, two different shuttles were poised on two different launch pads: Atlantis in the foreground and Endeavour - to launch in the unlikely event that a rescue mission was necessary during Atlantis mission to upgrade the Hubble Space Telescope. flic.kr/p/25YZQN9

One of the most surreal skies I have ever witnessed, as vibrantly blue undulatus asperatus clouds rolled over the St. Mark's Lighthouse at sunset to create this dreamy scene. #Photography

I am sure the astronauts are all VERY GOOD SPORTS and are more than happy to do whatever is asked of them for the sake of science but COME ON 😭

is this anything

Welcome home, Integrity! #spacecraftgijinka

Here's the full chute deployment and splashdown of the Integrity capsule containing the Artemis crew (at 1.5x speed to fit within the Bluesky video limit). Welcome home!

The Moon eclipsing the Sun from the perspective of the Artemis crew (2x speed). Incredible to watch this live and see the corona appear as soon as the disc of the Sun is fully covered.
