Galileo Galilei described the moon using earthly comparisons, invoking images of sunlight on craters, which shaped early perceptions of the lunar landscape.

Hubble captured the planet's reflected visible light and highlighted Saturn's iconic yellow hues, which are, in part, a product of the sunlight-reflecting ammonia crystals and hydrocarbons such as methane in its atmosphere.

The new work was less notable for showing that we had found these bases in Ryugu than for solving a previous mystery: earlier studies had failed to detect them there, despite their presence in many other asteroid samples.

Only 24 people have seen the far side of the Moon with their own eyes in the entire history of humanity. All of them were men, Americans, and white: the crew members of the nine Apollo missions that traveled to the Moon between 1968 and 1972.

We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.

Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.
