Galaxies in ultraviolet! 👀 The Hubble Space Telescope’s unique ability to capture high-resolution ultraviolet (UV) light is essential for observing the hottest, youngest stars and the energetic processes occurring within distant galaxies.
In this video, we look at galaxies that Hubble has observed in ultraviolet: NGC 1792, NGC 6984, NGC 3137, Messier 96, NGC 4571, NGC 685, Messier 74, NGC 7496, NGC 3511, and NGC 2566.

Supernova in a Sideways Spiral Video Credit: Hunter Outten & Kaleb Jordan Text: Cecilia Chirenti (NASA GSFC, UMCP, CRESST II)
Explanation: A long time ago, in a distant galaxy, a massive star was destroyed in a supernova explosion. The light of this event travelled for tens of millions of years and reached Earth last week as Supernova 2026kid. The featured video shows a time-lapse over three nights of the host galaxy NGC 5907, an edge-on spiral also known as the Splinter or Knife Edge Galaxy, as the supernova appears and becomes brighter. (The occasional streaks are satellites in Earth orbit.) At its brightest, a supernova can outshine the sum of all other stars in its galaxy. Supernova 2026kid appears relatively dim, probably because we are seeing it through the edge-on disk of the galaxy. Such explosions typically happen about once per century in galaxies similar to the Milky Way, and their light can take months to fade away. The brightest supernova in recorded history was SN 1006; it is reported to have been brighter than Venus, and even visible in the sky during daytime.

Plucking Droplets
A sudden breeze can pluck droplets hanging from a stem. Here, researchers recreate that phenomenon in the laboratory. With a close-up view and high-speed images, we can enjoy every detail of the detachment and break-up. (Video and image credit: D. Maity et al.)

Jupiter from the Webb Space Telescope Image Credit: NASA, ESA, CSA, Jupiter ERS Team; Processing: Ricardo Hueso (UPV/EHU) & Judy Schmidt
Explanation: This infrared view of Jupiter by Webb is illuminating. High-resolution infrared images of Jupiter from the James Webb Space Telescope (Webb) reveal, for example, differences between high-floating bright clouds – including the Great Red Spot – and low-lying dark clouds. Also clearly visible in the featured Webb image are Jupiter’s dust ring, bright auroras at the poles, and Jupiter’s moons Amalthea and Adrastea. The footprint of large volcanic moon Io’s magnetic funneling of charged particles onto Jupiter is also visible in the southern aurora. Some objects are so bright that light noticeably diffracts around Webb’s optics creating streaks. Webb, which orbits the Sun near the Earth, has a mirror over six meters across making it the largest astronomical telescope ever launched – with over six times more light-collecting area than Hubble.

Checklist song. United Airlines San Francisco International Airport 2025
It is really important to me that all of you learn about Al Bean, astronaut on Apollo 12 and the fourth man to walk on the moon, who after 20 years in the US Navy and 18 years with NASA during which he spent 69 days in space and more than 10 hours doing EVAs on the moon , retired to become a painter.
He is my favorite astronaut for any number of reasons, but he’s also one of my favorite visual artists.
Like, look at this stuff????
It’s all so expressive and textured and colorful! He literally painted his own experience on the moon! And that's just really fucking cool to me!
Just look at this! This is one of my absolute favorite emotions of all time. Is Anyone Out There? is like the ultimate reaction image. Any time I have an existential crisis, this is how I picture myself.
And then there's this one:
The Fantasy
For all of the six Apollo missions to land on the moon, there was no spare time. Every second of their time on the surface was budgeted to perfection: sleeping, eating, putting on the suits, entering and exiting the LEM, rock collection, setting up longterm experiments to transmit data back to Earth, everything. These timetables usually got screwed over by something, but for the most part the astronauts stuck to them.
The crew of Apollo 12 (Pete Conrad, Al Bean, and Dick Gordon) had other plans. Conrad and Bean had snuck a small camera with a timer into the LEM to take a couple pictures together on the moon throughout the mission. They had hidden the key for the timer in one of the rock collection bags, with the idea being to grab the key soon after landing, take some fun photos here and there, and then sneak the camera back to Earth to develop them. They had practiced where they would hide the key and how to get it out from under the collected rocks back on Earth dozens of times.
But when they got to the moon, the key was nowhere to be found. Al Bean spent precious time digging through the collection bags before he called it off. The camera had been pushing their luck anyways, he couldn't afford to spend anymore time not on the mission objectives. Conrad and Bean continued the mission as per the NASA plan while Dick Gordon orbited overhead.
Fast forward to the very end of the mission. Bean and Conrad are doing last checks of the LEM before they enter for the last time and depart from the moon. As Bean is stowing one of the collection bags, the camera key falls out. The unofficially planned photo time has come and gone, and he tosses the key over his shoulder to rest forever on the surface of the moon.
This painting, The Fantasy, is that moment. There have never been three people on the moon at the same time, there was never an unofficial photo shoot on the moon, this picture could never have happened.
"The most experienced astronaut was designated commander, in charge of all aspects of the mission, including flying the lunar module. Prudent thinking suggested that the next-most-experienced crew member be assigned to take care of the command module, since it was our only way back home. Pete had flown two Gemini flights, the second with Dick as his crewmate. This left the least experienced - me - to accompany the commander on the lunar surface.
"I was the rookie. I had not flown at all; yet I got the prize assignment. But not once during the three years of training which preceded our mission did Dick say that it wasn't fair and that he wished he could walk on the moon, too. I do not have his unwavering discipline or strength of character.
"We often fantasized about Dick's joining us on the moon but we never found a way. In my paintings, though, I can have it my way. Now, at last, our best friend has come the last sixty miles." - Al Bean, about The Fantasy.

To be honest, this one
Almost made me cry right now.
I love it. Something about it feels so incredibly human. The emotion on display, even without a face to show it. This is magnificent. Truly magnificent. I feel it in my soul.
I'm noticing that a few of the pieces of artwork have the iconic spacesuit bootprint as an overlay. It's a nice touch.
Lung Flows
When a fluid coats the inner walls of a cylinder, it can move downward in what’s called a collar flow. In our airways, a sinking collar flow can thicken as it falls, eventually blocking the airway completely. (Image and research credit: J. Shemilt et al.; via APS)
In Search Of...Avalanches
Our science goal is to monitor for avalanches. This area has fan deposits suggesting the likelihood of recent avalanche processes happening here. The location can help to test the role of carbon dioxide disappearance as an avalanche trigger. If there is any change detected, we want ot be best able to measure how much.

A Soft Cell in Microgravity
There are many shapes that can be tiled to fill space, but nearly all of them have sharp corners. Last year, mathematicians identified a new class of shapes, known as “soft cells,” that feature curved edges and faces but very few sharp corners. Like traditional polyhedrals, soft cells can tile to fill a space completely without overlapping or gapping. (Image and video credit: HUNOR/NASA; research credit: G.

What do you mean 12 years???????????
For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.
Entraining Bubbles
Every time I fill a glass at my refrigerator, I watch how the falling jet creates a cloud of bubbles. The bubbles form when the impacting water jet pulls air in with it, though, as this video shows, the exact origins can vary. (Video and image credit: S. Relph and K. Kiger)
