Orion Nebula, A year of learning

homie stepped into a different world

Hey Guys, I make realistic paintings of an explorer discovering strange creatures on an alien planet. It's all in a retro-futuristic setting, meaning everything looks like a vintage photograph. I thought you might be interested. (Links in comments)

Are there any more constellations in this picture that i took of the stars? the only one i can recognize is Orion.

M104: The Sombrero Galaxy, January 30th, 2022.

Every Satellite orbiting Earth and who owns them

About 95% of our galaxy's mass is dark matter, a mysterious substance that doesn't interact with light—but a new study suggests it may still be possible to measure its influence on our solar system: https://t.co/3HwCdEOTkk https://t.co/vKyyrGpM82

How do we know what Pluto is made of?

I just read that Pluto is made of ice. I thought “how do we know that? It’s so far away!” I did a little research and found out that we sent a space probe near it some years ago, but it still doesn’t answer my questions. I’ve seen articles from the early 90’s talking about the composition of Pluto. So, how do we know that Pluto is made of ice? Was this discovered only recently from the space probe, or has this been long known? If so, how?

Conducting Science

I would like to (hopefully) contribute to the body of knowledge that is Astronomy. Are any of you aware of ways this can be done as an amateur astronomer? If so, what sort of equipment/technology would I need? I just enjoy space and my equipment, and if I can help in any way that would be great. TIA

How does the next generation of large ground based optical telescopes compliment each other?

Hello, In the next decade or so four new large ground based optical telescopes will come online. ELT, TMT, GMT and LSST. I understand how LSST differs from the other three, but what are the main differences between the ELT, TMT and GMT? All three are large optical/near-infrared telescopes with adaptive optics. At first glance they don't look that different from each other (unless you count GMT mirror design). Do they differ in any fundamental way they can do science? Do we just build three similar ones to get more telescope time and different science instruments? TMT is in the northern hemisphere so I guess that's a valid point for having two similar ones, one in each hemisphere. Hopefully this is the right place to ask.

Kill the lights – we’re simulating a Moonwalk! Divers at NASA’s Neutral Buoyancy Laboratory turned off the lights to simulate what an Artemis astronaut might experience at the lunar south pole - long, dark shadows. https://t.co/naslhzzix7

[OC] I made a timelapse of the Moon

The crew stayed busy on Wednesday with robotics tests and experiments that will impact future space exploration, construction and nutrition. https://t.co/PiTaUl0Pdr

We’re highlighting stories of some of the stars who helped light the way in space exploration. @NASA's amazing discoveries could not have happened without the knowledge, courage and strength of Black Americans. We celebrate them not just for #BlackHistoryMonth, but every day. https://t.co/xQo21GLHLF
