Do you love the color of the—uh, well, does this even count as the sky anymore?
Astronaut Don Pettit took this photo from space in January 2025, as the Sun began to rise over a cloudy Pacific Ocean. This long-exposure image shows off the wide band of the Milky Way, our home galaxy, above the aurora and airglow that shine closer to Earth's horizon.
Astronaut Don Pettit has been to space four times: most recently, he spent 220 days on the International Space Station, returning to Earth in April 2025. Pettit grew space plants, printed 3D metal parts, and studied human health during his time in orbit. When he wasn't working on more formal studies, though, he found plenty of time for what he calls the "science of opportunity:" exploring and experimenting with his surroundings through a combination of science and art.
Pettit shares his experience with the art side of his time in space on our astrophotography episode of “Houston, We Have a Podcast” alongside astronaut Matt Dominick. Give it a listen here or on your favorite podcast app.
The full set is here! The last addition are the Chinese quails, I used to have them and I've got so much nostalgia for them <3
Tumblr being the "piss on the poor" reading comprehension site makes sense when you realize that 79% of adults in the US are functionally illiterate. Same goes for Twitter and TikTok.
that's a real high number, sport. where'd you get it?
hey anon
please tell me you didn't google "US literacy rates" and then make the funniest possible mistake one could make in that situation

excerpt from the original post: this is dictamnus albus—commonly called gas plant. on hot days, it emits a citrusy, flammable oil that briefly ignites when exposed to flame. it’s completely harmless to the plant, but incredible to witness.
Moonbows
A moonbow, also known as a lunar rainbow or white rainbow, is a rainbow created by moonlight rather than sunlight. It's formed when light from the moon refracts and reflects off water droplets, like those in rain or mist, creating a visible arc of light in the sky. Moonbows are generally fainter and less colorful than regular rainbows, and they are much rarer due to the need for specific conditions like a full or near-full moon, clear skies, and dark skies.
A growing baby planet photographed for first time in a ring of darkness
For the first time, a growing planet outside our solar system has been discovered to inhabit a gap in a disk of dust and gas.
A team of astronomers has detected for the first time a growing planet outside our solar system, embedded in a cleared gap of a multi-ringed disk of dust and gas.
The team, led by University of Arizona astronomer Laird Close and Richelle van Capelleveen, an astronomy graduate student at Leiden Observatory in the Netherlands, discovered the unique exoplanet using the University of Arizona's MagAO-X extreme adaptive optics system at the Magellan Telescope in Chile, the U of A's Large Binocular Telescope in Arizona and the Very Large Telescope at the European Southern Observatory in Chile. Their results are published in The Astrophysical Journal Letters.
For years, astronomers have observed several dozen planet-forming disks of gas and dust surrounding young stars. Many of these disks display gaps in their rings, hinting at the possibility that they are being "plowed" by nearby nascent planets, or protoplanets, like lanes being cleared by a snowplow. Yet, only about three actual young growing protoplanets have been discovered to date, all in the cavities between a host star and the inner edge of its adjacent protoplanetary disk. Until this discovery, no protoplanets had been seen in the conspicuous disk gaps – which appear as dark rings.
"Dozens of theory papers have been written about these observed disk gaps being caused by protoplanets, but no one's ever found a definitive one until today," said Close, professor of astronomy at the University of Arizona. He calls the discovery a "big deal," because the absence of planet discoveries in places where they should be has prompted many in the scientific community to invoke alternative explanations for the ring-and-gap pattern found in many protoplanetary disks.
"It's been a point of tension, actually, in the literature and in astronomy in general, that we have these really dark gaps, but we cannot detect the faint exoplanets in them," he said. "Many have doubted that protoplanets can make these gaps, but now we know that in fact, they can."
4.5 billion years ago, our solar system began as just such a disk. As dust coalesced into clumps, sucking up gas around them, the first protoplanets began to form. How exactly this process unfolded, however, is still largely a mystery. To find answers, astronomers have looked to other planetary systems that are still in their infancy, known as planet-forming disks, or protoplanetary disks.
Close's team took advantage of an adaptive optics system, one of the most formidable of its kind in the world, developed and built by Close, Jared Males and their students. Males is an associate astronomer at Steward Observatory and the principal investigator of MagAO-X. MagAO-X, which stands for "Magellan Adaptive Optics System eXtreme," dramatically improves the sharpness and resolution of telescope images by compensating for atmospheric turbulence, the phenomenon that causes stars to flicker and blur, and is dreaded by astronomers.
Suspecting there should be invisible planets hiding in the gaps of protoplanetary disks, Close's team surveyed all the disks with gaps and probed them for a specific emission of visible light known as hydrogen alpha or H-alpha.
"As planets form and grow, they suck in hydrogen gas from their surroundings, and as that gas crashes down on them like a giant waterfall coming from outer space and hits the surface, it creates extremely hot plasma, which in turn, emits this particular H-alpha light signature," Close explained. "MagAO-X is specially designed to look for hydrogen gas falling onto young protoplanets, and that's how we can detect them."
The team used the 6.5-meter Magellan Telescope and MagAO-X to probe WISPIT-2, a disk van Capelleveen recently discovered with the VLT. Viewed in H-alpha light, Close's group struck gold. A dot of light appeared inside the gap between two rings of the protoplanetary disk around the star. In addition, the team observed a second candidate planet inside the "cavity" between the star and the inner edge of the dust and gas disk.
"Once we turned on the adaptive optics system, the planet jumped right out at us," said Close, who called this one of the more important discoveries in his career. "After combining two hours' worth of images, it just popped out."
According to Close, the planet, designated WISPIT 2b, is a very rare example of a protoplanet in the process of accreting material onto itself. Its host star, WISPIT 2 is similar to the sun and about the same mass. The inner planet candidate, dubbed CC1, contains about nine Jupiter masses, whereas the outer planet, WISPIT 2b, weighs in at about five Jupiter masses. These masses were inferred, in part, from the thermal infrared light observed by the University of Arizona’s 8.4-meter Large Binocular Telescope on Mount Graham in Southeastern Arizona with the help of U of A astronomy graduate student Gabriel Weible.
"It's a bit like what our own Jupiter and Saturn would have looked like when they were 5,000 times younger than they are now," Weible said. "The planets in the WISPIT-2 system appear to be about 10 times more massive than our own gas giants and more spread out. But the overall appearance is likely not so different from what a nearby 'alien astronomer' could have seen in a 'baby picture' of our solar system taken 4.5 billion years ago."
"Our MagAO-X adaptive optics system is optimized like no other to work well at the H-alpha wavelength, so you can separate the bright starlight from the faint protoplanet," Close said. "Around WISPIT 2 you likely have two planets and four rings and four gaps. It's an amazing system."
CC1 might orbit at about 14-15 astronomical units – with one AU equaling the average distance between the sun and Earth, which would place it halfway between Saturn and Uranus, if it was part of our solar system, according to Close. WISPIT-2b, the planet carving out the gap, is farther out at about 56 AU, which in our own solar system, would put it well past the orbit of Neptune, around the outer edge of the Kuiper Belt.
A second paper published in parallel and led by van Capelleveen and the University of Galway details the detection of the planet in the infrared light spectrum and the discovery of the multi-ringed system with the 8-meter VLT telescope’s SPHERE adaptive optics system.
"To see planets in the fleeting time of their youth, astronomers have to find young disk systems, which are rare," van Capelleveen said, "because that's the one time that they really are brighter and so detectable. If the WISPIT-2 system was the age of our solar system and we used the same technology to look at it, we'd see nothing. Everything would be too cold and too dark."
TOP IMAGE: The WISPIT 2 system as seen by the Magellan Telescope in Chile and the Large Binocular Telescope in Arizona. The protoplanet WISPIT 2b appears as a purple dot in a dust-free gap between a bright, white dust ring around the star and a fainter, outer ring, orbiting at about 56 times the average distance between the Earth and the sun. The other potential planet, CC1, appears as the red object inside the dust free cavity and is estimated to be about 15 Earth-sun distances from its host star.

LOWER IMAGE: In this artist's illustration, infalling hydrogen gas causes the growing protoplanet WISPIT 2b to shine brightly in the hydrogen alpha spectrum, to which the MagAO-X instrument is particularly sensitive. For years, astronomers have observed several dozen planet-forming disks of gas and dust surrounding young stars. Many of these disks display gaps in their rings, hinting at the possibility that they are being "plowed" by nearby nascent planets, or protoplanets, like lanes being cleared by a snowplow. Yet, only about three actual young growing protoplanets have been discovered to date, all in the cavities between a host star and the inner edge of its adjacent protoplanetary disk. Until this discovery, no protoplanets had been seen in the conspicuous disk gaps – which appear as dark rings.
