The Orion Nebula, one of the "stars" in the constellation Orion, is 1400 light years away.

Different types of stars have different magnitudes, and can be visible at different distances, as do other objects, like nebulas.

And yes, with a telescope, you can see numerous additional stars. The Milky Way becomes a boring group of stars when viewed through a telescope, because they are no longer tightly packed.

You can clearly see the Space Shuttle era on this graph.

The helmet only attaches to the white garment. Also only the white garment has the hose connectors. But I wonder what's up with the rings on the green garment.

Until 1 of those rockets carrying the nuke fails and explodes... killing thousands.

Some are non-binary, I’m sure

I've been keeping track of Dava Newman's work on the MIT prototype BioSuit for the past several years, and spacesuit tech just keeps getting better and better. I think future suits will also be three layers: body stocking-type skinsuit layer, smart mechanical counterpressure layer with hard seals, and a coverall-type thing with radiation shielding, pockets, and so on. Snap on some gloves, boots, and a helmet and be good to go.

Wow, this really underscores how consistent the Russians have been with their manned space program. Decades of almost constant levels.

I think it's pretty obviously implied that the aliens we're discussing have some kind of equivalent intellectual construct that mirrors our "constellations".

Thank you. I haven't used any star tracker. All the images are 5' exposure ones, stacked in post

If your life depended on counting change, you would have incentive to get it right

When asteroids are coming this close to earth, they really want to make sure of the trajectory, in case of impact.

Wow, learning something new every day. Odd rule though, surely there must be a good reason

Because they’re a private company

Why would they not be included as us launches?

I was in sixth grade and had a similar experience. We were in NH so Christa McAuliffe was a local hero of sorts. We were all pulled out of class to watch the launch in a common area, only to see the explosion and the see it replayed a bunch more times. Shocking and saddening.

If they have a higher magnitude we can see them with the naked eye

I remember it clearly. I was a college senior at the University of Florida. Everything stopped. Classes were canceled for the rest of the day.

Are SpaceX launches counted as a U.S. launch, or not included in the chart?

Potato or egg shaped caused by impact of other objects or it just formed this way from its beginning?

Excerpt:

>The space rock, known as 2023 BU, zoomed over the southern tip of South America [on 26 Jan. 2023], while it was only around 2,200 miles above the surface of the Earth.

>This is one of the closest approaches of an near-Earth object ever recorded. Data from NASA's Center for Near Earth Object Studies showed that the flyby of 2023 BU was the fourth-nearest of more than 35,000 past and future Earth close approaches in the 300-year period from 1900 to 2200.

>As the asteroid flew past our planet, astronomer Gianluca Masi of the Virtual Telescope Project (VTP) managed to capture some images.

>The VTP is a service provided by the Bellatrix Astronomical Observatory in Ceccano, Italy, that operates and provides access to robotic, remotely operated telescopes.

>"We managed to capture this extraordinary footage, showing such an extremely close and fast asteroid," Masi told Newsweek.

>Masi captured the images with the "Elena" robotic telescope unit, which is capable of tracking the very fast motion of asteroids flying past Earth.

>The images used to create the time-lapse video were captured when 2023 BU was around 13,600 miles above the surface of our planet.
