During thunderstorms, electric discharges in the air cause trees to glow with an ultraviolet aura. You can't see it with your eyes, but researchers have finally managed to measure it & recreate it in the lab. 🧪🔭 news.agu.org/press-releas...

We have some really, really cool photos of the Moon. This is one—of Malapert massif, one of the candidate Artemis III landing sites. Taken from an oblique angle by the Lunar Reconnaissance Orbiter Camera on 3 March 2023, the image is about 50 km across in the foreground. Credit: NASA/GSFC/ASU

A cool thing in these JWST 🔭 Uranus infrared images -- ASIDE from the (artificially-blue) polar cap & the dynamic bright clouds -- is the imaging of the aurora! It is the reddish glow extending above the clouds (e.g. 10 o'clock in the image on the right) www.scientificamerican.com/article/new-...

Fun little paper we published last month got picked up by earth.com. The author got it mostly right. There was no press release so he seemed to go above and beyond and read the paper and some citations in it and used references. Nice work. #scicomm 🧪 www.earth.com/news/antarct...

(1/2) #JWST NIRSpec observations of planet #Uranus from yesterday (2026-02-20). I tried to get a colored image (first image). Blue is 2.88 to 3.1 Microns, orange is 4.21 to 5.02 Microns.

There were requests for textures from my maps in more suitable projection for use in other projects. I have most of them directly in projections used in maps. The exception is the Pluto map where I made the base map directly in the cylindrical projection, so here it is www.flickr.com/photos/10958...

This is the first (correctly-exposed) photograph of Earth taken by a human from space, captured 64 years ago today by NASA astronaut John Glenn from inside his Friendship 7 capsule during the Mercury-Atlas 6 orbital mission on February 20, 1962.

This week’s image is of IC 5148! Gemini South’s GMOS was used to observe this planetary nebula, whose cloud of gas is expanding outwards at a speed of 180,000 km/hr! Check out the 🧵 for more papers involving GMOS data! #Astronomy

These little worlds are fascinating. Given the little swarms around Uranus and Neptune, plus the whole host of KBO objects, it is enough to wet one's appetite, but our datasets are so limited.

The Vandenberg launch of February 14th, 2026 was optimally timed for illumination of the initial as well as the lingering plume. Tonight this plume underwent intriguing looping and stretching as Earths shadow passed across it with reds, golds and blues dominating the last lighting here and there.

The deposits around the volcano Pele on Io looked like a heart as Voyager 1 approached in March of 1979. For today, I rotated it around to emphasize that. By the time Galileo saw it in 1996, the indentation at the top of this image was mostly gone. Happy Valentine's Day!

This is a real timelapse video of the Moon transiting in front of the Earth. It was captured by the Artemis 1 Orion spacecraft in November 2022 while flying at it's furthest point from the Earth. The video covers about 3.75 hours of real time. 🔭🧪

Sixty years ago today, on February 3, 1966, Luna-9 was the first spacecraft to survive landing on the surface of another world. It is wild to think that the Space Age is so young that there are still millions alive now who were adults when this happened.

A few months ago they let me walk around the Goldstone Deep Space Communications Complex at night. Don't know if it was the desert rain, watching skyscraper-sized antennas swivel to catch signals from beyond Saturn, or just my fillings buzzing from the radio signals, but I had goosebumps all night.

Titania is the largest of the Uranian moons. While Voyager couldn't fly close to it and still get to Neptune, it recorded more images of it than any other moon. The surface appears cratered with some clear tectonic features. The highest resolution images were at 4.5 km/pixel.
