Our @NASAArtemis #Orion spacecraft is making #selfie history, capturing itself with our entire home planet and all of mankind. It’s plain to see from this perspective that we humans are truly one, all in this together in our one common home. Almost halfway to the Moon already! https://t.co/cqDoEMlWWj

Artemis Launch from the VAB parking lot! (OC)

The James Webb Telescope has discovered a pair of earliest forming galaxies. They started forming only 100 million years after the Big Bang, which happened 13.8 billion years ago. These galaxies look remarkably different from the mature galaxies seen around us today.

How to collimate?

I just got a gigantic reflector telescope, and I have no idea how to collimate it. I’ve had refractors before, but this is my first reflector. I don’t have any tools so I’m probably going to make a collimating cap but I can’t find how to do it anywhere(or atleast in simpler terms) could someone help me and explain it to me like I’m 5 please?

It’s official: LightSail 2 has reentered Earth’s atmosphere and burned up, as expected. What a phenomenal mission this was! We are proud of everything this spacecraft accomplished, and of all the people who made it happen. https://t.co/wfSQxSdoMd

Happy 60th birthday @Dulles_Airport! 🎂🥳🎉 The airport was opened #OTD in 1962. Many of our artifacts have since landed themselves on its runways, as the Udvar-Hazy Center is nearby. Thanks for your support, Dulles! https://t.co/fystEN8EDV
