Garbage in space

There are thousands of satellites that orbit Earth, with about half of them launched in the past three years. Financial Times shows why that’s a problem in a scrolling piece through space debris: In 1978, Nasa astrophysicist Donald J Kessler outlined a theory of what would happen if space traffic continues to grow and collisions occur. The debris created by those collisions would skitter off into the paths of other...

Scale of the bigger, more detailed universe

We’ve learned more about the universe since Charles and Ray Eames produced Powers of Ten in 1977, so the BBC made an homage to the film, updating with what we know now. Spoiler alert: the universe is still big. Tags: BBC, scale, space

Scale of black holes

I’m not sure there’s any way to really understand the scale of the largest black holes in the universe, but Kurzgesagt gives it a good try. Tags: black hole, Kurzgesagt, scale, space

Launching a telescope to explore the Big Bang

NASA is launching the James Webb Space Telescope on December 22, 2021 with an objective to collect data on light from 13.8 billion light-years away. Using 3-D models from NASA, Rahul Mukherjee and Lorena Iñiguez Elebee for The Los Angeles Times show how the $10 billion telescope works and how NASA plans to launch the telescope into orbit a million miles from Earth. Nothing to it. Tags: Los Angeles Times,...

A view from the Moon’s south pole

NASA Goddard visualized the point of view from the south pole of the Moon, based on years of data collection to map the Moon’s surface. The result is a data-based time-lapse that shows Earth moving up and down and long shadows because the run shines at a low angle. It’s a neat contrast to what we see from Earth and makes me wonder what other points of view there are....

How long it takes a ball to drop on various Solar System bodies

James O’Donoghue made this straightforward animation that shows how long it takes for a ball to drop one kilometer on different planets: It might be surprising to see large planets have a pull comparable to smaller ones at the surface, for example Uranus pulls the ball down slower than at Earth! Why? Because the low average density of Uranus puts the surface far away from the majority of the mass....

What if a giant banana was orbiting Earth

yeti dynamics imagined if a giant banana were orbiting Earth from the same distance as the International Space Station: It’s so dumb, which is why it’s so good. And you’re in luck, because this video is from a few years ago, and yeti dynamics has many variants, such as: if the moon were replaced by planets and if all the planets were in between Earth and the moon. [via kottke]...

Spacecraft orbits

For The New York Times, Jonathan Corum illustrated the dozens of spacecraft orbiting planets and objects in the Solar System. The piece starts at the sun and then makes it way towards interstellar space. Showing active and inactive spacecraft, it’s part history lesson and part cute animation.

Everything in the universe

In this video, Dominic Walliman attempts to illustrate and explain all of the known things in the universe. There’s also a poster version. Tags: Dominic Walliman, space
