Size can surprise!
The real size of things ~ A Thread🧵 1. The actual size of Africa
Zooming closer and closer to a ball point pen.
19. This is what a pen looks like under an electron microscope
A great zoom in, like in the second part of Eames Powers of Ten. Is the final portion simulated? What do you think?
Nice ratio: if the Milky Way was the size of North America, our solar system would be the size of a quarter.
Universal zoom app can zoom from bacteria to the stars.
Size comparison from microscopic objects to the Observable Universe with the Universal Zoom app.
Good to be reminded, the planets' rotation form a helix.
Our sun orbits the center of the galaxy at 828,000 km/h (514,000 mph) There's a really cool model that views our solar system as a kind of helix shaped vortex, not a static disk with the sun motionless in the center. Cool video illustration below...
Simpson's version of the Eames Power of Ten zoom out.
In the spirit of Eames Powers of Ten, a new zoom out. Nice touch at the end-- the multiverse.
Nice animation, each celestial body rotates
One more: UY Scuti is the largest star in the Universe observed so far. The red supergiant is 1,708 times wider than our Sun, with a radius of 1.2 billion km (738 million miles).
26. Pale Blue Dot is a photo of Earth taken by Voyager 1 in 1990 from about 6 billion kilometers (3.7 billion miles) away, as it was leaving our solar system. As Carl Sagan put it: "Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone…
24. Looking up at the night sky, you can see thousands of stars and they’re just a fraction of the numerous stars in the universe
22. Here’s how Saturn’s rings would look like if they were placed around Earth
19. The James Webb Space Telescope has captured images of the four largest planets in our solar system: Jupiter, Saturn, Uranus, and Neptune. Neptune, the fourth largest planet, is about four times wider than Earth with an equatorial diameter of about 30,775 miles.
18. A logarithmic chart of distances, showing Voyager, our Solar System, the Oort Cloud, and our nearest star: Proxima Centauri.
17. Temperatures across our Solar System The temperature of a planet is strongly influenced by its distance from the Sun. Earth, located about 150 million km from the Sun, has a habitable climate, while distant planets like Neptune, over 4.5 billion km away, are much colder.
16. This vertically oriented logarithmic map of the Universe spans nearly 20 orders of magnitude, taking us from planet Earth to the edge of the visible Universe. Each large “mark” on the right side’s scale bar corresponds to an increase in distance scales by a factor of 10.
