You all should know that now, 20 years into teaching astronomy, I open every single class with that day's APOD. Sometimes it is spot-on for what we are studying at the time. At other times it opens doorways into new lines of discussion and thinking. Thank you.


Does anything orbit the Moon?

Yes! A handful of satellites currently orbit the Moon and, now, so does #CAPSTONE! This microwave oven-sized satellite will test a unique halo-shaped orbit to support @NASAArtemis & @NASA_Gateway missions: go.nasa.gov/3URKmHc

doesn’t the earth orbit the moon (technically)?

great explanation clip & great you are on mastodon!


On the sixth day of its mission, @NASA_Orion approached the Moon, passing over several Apollo landing sites and as close to 80 miles (128 km) above the lunar surface.

Live Now: Experts from @NASAArtemis and @NASA_Orion discuss the spacecraft's lunar flyby as it moves toward a distant retrograde orbit.

Orion’s closest approach was around 80 miles (128 km) above the Moon’s surface. twitter.com/i/broadcasts/1dRKZ…

.@Snoopy serves a very important purpose during the #Artemis I mission. He is our “zero-g” indicator — meaning that his floatation indicates microgravity levels aboard the @NASA_Orion spacecraft!

An eclipse on the way home 📸

#OTD in 1969, Apollo 12 astronauts captured a photograph of the eclipse of the Sun on their return to Earth. The view was created when the Earth moved directly between the Sun and the Apollo 12 spacecraft.

Earthset. 🌎

@NASA_Orion captured this shot of Earth “setting” while the spacecraft passed close to the Moon. Nearly 270,000 miles (430,000 km) away, #Artemis I will soon surpass Apollo 13’s record-setting distance from Earth in a spacecraft designed to carry astronauts.

Wildly mind bending but should not be surprising. I suppose it is my very human and earth-bound reaction.

Our @NASA_Orion spacecraft will soon break the record for the farthest distance traveled from Earth by any human-rated spacecraft, a record set during the Apollo era.

To the unaided eye, the Orion Nebula appears as a tiny, hazy spot within the sword of the constellation Orion. But it’s a vast stellar nursery of roiling dust and gas where vast numbers of new stars are forming. #MondayMotivation

Human ingenuity is so amazing to me. The logistics of what goes into this mission blows my mind. Sometimes I have to tie the same shoe multiple times in the same day. Cheers to the brilliant people who made this happen 🙌

As #Orion makes its closest lunar approach today, 53 years ago the Apollo 12 astronauts were in lunar orbit preparing to head back home! The Yankee Clipper command module performed a trans-Earth injection, leaving lunar orbit #OTD at 3:49 pm ET.

The Butterfly Nebula from Hubble
Stars can make beautiful patterns as they age -- sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot.

oops looks like you forgot alt text - there’s a handy delete and redraft button where you can add a description so the visually impaired get to know about what’s in the image 😃

#OTD in 1969, Apollo 12 astronauts Pete Conrad and Al Bean walked out to visit the inactive Surveyor 3 spacecraft that had been on the moon since 1967; collecting its TV camera, robotic scoop, and some cables, tubing, and glass for a return to Earth.

Back on Earth, scientists were initially perplexed when they were able to grow bacteria from swabs from the Surveyor 3 camera the Apollo 12 crew brought back!

Today marks our namesake Edwin Hubble’s birthday! 🎂

Our telescope is named after him, and so is the Hubble Constant – the rate at which our universe expands.

excellent video, I knew Hubble's observations were responsible for knowing the expansion but never heard of the Hubble constant, thanks!

Spacecraft get selfies, too.

While teams performed a checkout on the @NASA_Orion spacecraft, these images were captured of the outside of the vehicle.

When a spacecraft takes a selfie is the photo free or is there someone who owns the photo rights 🤔
