I mean, there are plenty of good deep sky images out there. Try looking at the New General Catalogue (NGC) objects for something that strikes your fancy. Alternatively, you could cruise around in Space Engine and bookmark an interesting galaxy to get screenshots from multiple angles, which is what I usually do. (SE is available on Steam for a reasonable price.). Source: 10 months ago
Computer says yes: https://gravitysimulator.org/ https://spaceengine.org/ Once the mass, velocity, heading of an object is known it becomes easier to track and fine tune parameters meaning time of intersect with earth can be calculated which gives orientation of planet and entry attitude. An exact street addres | sub metre grid reference is a big ask, but the "line of breakup" arcing across a narrow slice of the... - Source: Hacker News / 10 months ago

This is a bit of a tall order. There are none that I know of; most folks I know who do galaxy maps either make them by hand with their digital paint tools of choice, or utilize the procedurally-generated ones from Space Engine. Up until recently SE had a free (old) version available on the site; you should still be able to find a mirror of it somewhere but I don't know of one personally. Otherwise, SE is available...

Numbers as overwhelming as these are meaningless to our little minds. Then, do yourself a favor. Download Space Engine and see for yourself what it's like to visually behold the mindblowing immensity we are talking about. Now, take into account Multiverses, and consider the possibility that all those Universes may be fractal-like with n-infinite dimensions. Contemplate that we probably know absolutely nothing...

The Heavens Above site will give predictions of satellite passes based on location and time, and will predict brightness as well. For example, here's a guess at the 501 location for last night (you might have to set the date yourself). Looks like the SL-16 R/B satellite or the Resurs 01 rocket stage are good candidates; they're about the right time and direction. If you knew time, location, and/or direction more...

Also worth noting: https://heavens-above.com/main.aspx But this has a much nicer UI/UX! The street view rendering is particularly impressive. - Source: Hacker News / about 3 years ago
I have seen planes where they look like just flashes of lights until you get into a really dark place and can see the lights that are always on. I think they fly at higher altitudes for faster, more efficient travel. There are a couple of ways to check into this, though. Heavens-Above tracks satellites and flightradar24 has a playback function for times going back a week. Source: about 3 years ago
