Hand-drawn map of the Ottoman Empire created in 1855 by cartographer Heinrich Kiepart (1818-1899). It is pretty crazy how detailed, accurate, and visually stunning some of these old maps are. Citation in comments. [9360  ×  6686]

Rome goes on a rampage in the 3rd and 4th Century AD and conquers more land. By the end of the 5th Century, it reaches its largest territorial extent.(Image credit: HelloThereItsMeandMe)

IC 4633 recently imaged by Hubble. The spiral galaxy is rich in star-forming activity and has many tightly-wound spiral arms, each home to 10's of billions of stars and untold numbers of planets. It also hosts an active galactic nucleus at its center. (Image credit: ESA/Hubble & NASA, J. Dalcanton)

Atlases of relief maps that show what would happen to cities located on the shores of the oceans and seas if the world’s oceans rise by 70 meters (230 feet), as a result of all the ice covering Antarctica, Greenland, and mountain ice-caps melting. (Credit: Neahga Leonard)

Hubble's view of 2 huge star clusters thought to be merging together at the center of the Tarantula Nebula. This area contains many of the most massive and luminous stars known to science, with a couple of them being several million times more luminous than the Sun. (Credit: NASA, ESA, & E. Sabbi)

The Carpathian Mountains and surrounding area always looks so good on relief maps. I took out the rivers to better highlight the terrain, but it is still pretty obvious where they are.

What on Earth was it about Marcus Agrippa that made him such an unbelievably effective and brilliant military commander?

“Triumphs of Caesar” by the Italian Renaissance artist Andrea Mantegna, depicting a triumphal military parade celebrating Caesar’s victory in the Gallic Wars.

Messier 101, one of the largest known spiral galaxies. It is 170,000 light-years across, and is home to 1 trillion stars. For reference, the Milky Way is 100,000 light-years across, with roughly 200 billion stars. I can not even begin to imagine how many habitable worlds exist there. (ESA/Hubble)

Still one of the most beautiful images Hubble has ever captured, NGC 1300. It is hard for our monkey brains to truly grasp that the object we're looking at is over 110,000 light-years across. There is just no way that we can be alone in the Universe. No. Way. (Credit: NASA/ESA, Hubble Heritage Team)

It’s pretty hard to overstate how the vital the conquest of the Dacian Kingdom was for the Empire’s future.

Caldwell 101, the Milky Way's cosmic twin, as it shares a remarkably similar anatomy to our home galaxy. But Caldwell 101 is way bigger, spanning 175,000 light-years across. This makes it one of the largest known spiral galaxies. (Credit: NOIRLab, R. Colombari & M. Zamani)

Old geological maps of U.S. states that have been updated using digital elevation data and added shaded relief of geographic features.

Vintage soil and land classification map of Africa from 1923 combined with elevation data and shaded relief. Shows tropical/subtropical agriculture, grazing land & forest land, coinciding w/ colored legend.

It always amazes me how well Hubble sees things compared to telescopes on Earth. Pic on left was taken by amateur Johnny Qiu, while pic on right is from Hubble (both of spiral galaxy Caldwell 30). Strangely, this galaxy's central bulge spins in the opposite direction to the galactic disc itself.

How would an Ancient Roman smell to someone from a modern day society today?
