The National Indian Child Welfare Association needs your help before September 17th 2024
Text SIGN PBAZHN to 50409 to send this letter to your US House Representative
Please support H.R. 9076 when it reaches the house floor. Native families deserve support from the federal government, especially when it comes to keeping Native children with Native families. This bill includes critical provisions for tribes that receive funding under the Title IV-B child welfare programs, such as: - Increasing funding for tribal agencies and courts. - Reducing administrative burdens. - Enhancing data collection on Indian Child Welfare Act (ICWA) cases in states.
Please sign and share, it takes about 30 seconds to use resist bot. Thank you!
good omens broke me so now i’m learning how to paint nebulas (wip. still a loooottt to work on)
[Image Description: A digital painting of a nebula/nebulae. At the top left corner there’s red dust forming a little heart. The rest of the drawing is still unfinished and shows nebulae of different colors like light blue, orange, yellow, and green. Behind the nebulae, little and big stars are visible. Second image is close-up of the top left corner. /end ID]
Wouldn't it be nice to live among the stars?
this is so cool are u guys seeing this!!!!!
A new image shows at least 17 dust rings created by a rare type of star and its companion locked in a celestial dance.
I knew we’d get decent images of one eventually… 😄

Rockets, Racecars, and the Physics of Going Fast
When our Space Launch System (SLS) rocket launches the Artemis missions to the Moon, it can have a top speed of more than six miles per second. Rockets and racecars are designed with speed in mind to accomplish their missions—but there’s more to speed than just engines and fuel. Learn more about the physics of going fast:
Take a look under the hood, so to speak, of our SLS mega Moon rocket and you’ll find that each of its four RS-25 engines have high-pressure turbopumps that generate a combined 94,400 horsepower per engine. All that horsepower creates more than 2 million pounds of thrust to help launch our four Artemis astronauts inside the Orion spacecraft beyond Earth orbit and onward to the Moon. How does that horsepower compare to a racecar? World champion racecars can generate more than 1,000 horsepower as they speed around the track.
As these vehicles start their engines, a series of special machinery is moving and grooving inside those engines. Turbo engines in racecars work at up to 15,000 rotations per minute, aka rpm. The turbopumps on the RS-25 engines rotate at a staggering 37,000 rpm. SLS’s RS-25 engines will burn for approximately eight minutes, while racecar engines generally run for 1 ½-3 hours during a race.
To use that power effectively, both rockets and racecars are designed to slice through the air as efficiently as possible.
While rockets want to eliminate as much drag as possible, racecars carefully use the air they’re slicing through to keep them pinned to the track and speed around corners faster. This phenomenon is called downforce.
Steering these mighty machines is a delicate process that involves complex mechanics.
Most racecars use a rack-and-pinion system to convert the turn of a steering wheel to precisely point the front tires in the right direction. While SLS doesn’t have a steering wheel, its powerful engines and solid rocket boosters do have nozzles that gimbal, or move, to better direct the force of the thrust during launch and flight.
Racecar drivers and astronauts are laser focused, keeping their sights set on the destination. Pit crews and launch control teams both analyze data from numerous sensors and computers to guide them to the finish line. In the case of our mighty SLS rocket, its 212-foot-tall core stage has nearly 1,000 sensors to help fly, track, and guide the rocket on the right trajectory and at the right speed. That same data is relayed to launch teams on the ground in real time. Like SLS, world-champion racecars use hundreds of sensors to help drivers and teams manage the race and perform at peak levels.
Knowing how to best use, manage, and battle the physics of going fast, is critical in that final lap. You can learn more about rockets and racecars here.

A nebulous horse’s head.
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.
There’s also Alexei Leonov, writer and artist and first person to conduct a spacewalk!
This is his art.
You can't forget this, the first art made in space.
March 1965, Alexei Leonov made this drawing only moments after narrowly surviving the very first space walk.
no offense but if they did this i would become a terrorist
there are multiple international organizations rallying against this kind of light pollution. if you want to prevent this from happening, you can directly support them by joining iniatives such as the international dark sky association advocacy program, or the international astronautical union and their dark skies for all initiative.
this topic has also recently been introduced to the united nations committee on space affairs, so you can also reach out to your appropriate ministry to prioritize the introduction of laws against this. save the night!
