I use the one from timeanddate.com, it seems to have better predictions than others for my area. Source: 12 months ago

Timeanddate.com has the sunrise/set data in an api. Source: 12 months ago

True, this, and all one has to do is look at solar noon altitudes from any place on earth on web sites like timeanddate.com. It helps when anybody local can verify these numbers (I used them to build a sundial so discrepancies would be noticed). Source: about 1 year ago

I always wondered if it's a satire of https://timeanddate.com - except that's probably not as well known as it deserves to be. Source: about 1 year ago

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.

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 / 11 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...
