Here's one of Juno's views of Ganymede's day side.

A slice of exploration. OTD in 2007 while en route to Pluto, NASA's New Horizons spacecraft captured this look at Jupiter's moon Ganymede silhouetted against the planet's crescent. Today, our Juno mission orbits Jupiter, and Europa Clipper is on its way: science.nasa.gov/jupiter/expl...

Yep. And a treasure trove of results.

I, too, always measure things in Cassinis.

(It's a *very* depressing exercise these days.)

Thoughts & prayers to the EPA :(

Sweet dreams, everyone 🖤 (art Lucy Campbell)

How Lebanon, TN Rejected an ICE Detention Center - City Cast Nashville After weeks of confusion and public outcry, ICE is no longer planning to put a detention center that could house up to 16,000 immigrants right down...

After weeks of confusion and public outcry, ICE is no longer planning a mega detention center in Lebanon, TN. Many are relieved, including Wilson County mayor Randall Hutto, who joins us today to explain how the whole thing went down, and why he pushed back.

This is what weak and insecure people think confidence looks like: buffoonish bluster and swagger, like a 12-year-old bully. It doesn‘t inspire trust or security. It inspires grave concern for the lives of the people serving our nation whose fate is in the hands of these overcompensating oafs.

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Niiiiice!

This composite image from New Horizons shows Jupiter and its moon Io during the 2007 flyby. Jupiter, in false-color infrared, displays swirling cloud bands with the Great Red Spot as a prominent bluish-white oval storm. Warmer lower clouds appear reddish, higher hazes blue, highlighting atmospheric dynamics. Io, in near-true color, is superimposed. Its night side reveals a bright red glowing lava eruption at Tvashtar volcano, with a 330-km-high blue-tinged plume rising above, lit by scattered sunlight. The montage contrasts Jupiter’s vast atmosphere with Io’s intense volcanic activity during the gravity-assist maneuver.

In Feb 2007, New Horizons passed Jupiter & its active moon Io. ⚛️

In this nice montage, Jupiter was captured in 3 bands of infrared light making the Great Red Spot look white.🧪

Io is digitally superposed in natural color, showing an ongoing eruption.🔭

YouTube video by Senator Elizabeth Warren I just left a classified briefing with the Trump Admin about the war in Iran.

I was worried before, but I’m more worried now.

I feel like we typically see these sorts of completely outraged opinions from federal judges a couple times a year across the whole country, maybe a little more often in last few years. Now, in cases stemming from Trump's immigration crackdown, judges are ringing the alarm bell several times a week.

Oh, didn't realize that. Looking forward to hearing it.

Nearly fully eclipsed red Moon in a starry sky with some clouds. Intentional long-exposure motion blur in the clouds - UNintentional motion blur in the rest.

Uh, nice try anyway (I think I just bumped the tripod)

The perfect tool for enranging your strategic relationships. I mean, that’s just counology.

Separate studies demonstrated 20% increase in additional hours and a 17% drop in actual knowledge as ascertained by a quiz on the code they had just written with AI assistance versus the control group without.

Boophis reticulatus, a brown tree frog with weird ridges on its back, perched on a serrated bright green Pandanus leaf.

Platypelis pollicaris, a little brown narrow-mouth frog with flecks of gold over its body, sitting atop a bright green leaf

A female Calumma oshaughnessyi, a large green and grey chameleon with diagonal stripes up its body, walking along a branch toward camera left.

A portrait of Liopholidophis dolicocercus (sorry if you’re using a system that reads these Latin names aloud!), a black, brown, and bright yellow snake. In my years working with snakes in Madagascar, I think I have never had a more cooperative subject. It was totally calm and posable!

Yesterday we hiked out of the forest after five days totally off-grid. Hard to believe what’s happened in the world in the last five days! I’m quite glad we were out of signal range and able to focus on just excellent frogs and reptiles. 🧪🐸🦎🐍🇲🇬

I'm delighted to see that my @science.esa.int Mars Express VMC video is featured on today's #APOD 🔭

Good morning

Follow along with LRO before, during, and after the eclipse using our Eyes on the Solar System experience: go.nasa.gov/4gswDkZ

To make it through, the team will temporarily turn off the science instruments & the main antenna, saving power to bring LRO back online after the eclipse. Learn more about LRO, which has been sending stunning images & other data from the Moon since 2009: science.nasa.gov/mission/lro/

From NASA

From the Moon, a lunar eclipse looks like a total solar eclipse, but it lasts a LOT longer. For NASA's Lunar Reconnaissance Orbiter, that means the team has to plan carefully for the 4 hours that the spacecraft — and its solar panels — will be in the dark and the cold.
