Gigapixels of Andromeda

daveachuk brings us a zoom-in of a high-resolution picture of our neighboring galaxy Andromeda taken by the Hubble Space Telescope:

Can you count the number of stars?

If the Moon Were Only One Pixel

What if the moon were only one pixel in size? How would the solar system look? Let Josh Worth show you.

Doze Off Like an Astronaut

The High Definition Earth-Viewing System (HDEV) isn’t new, but it’s still amazing, and it’s just about the only way you can see the sun set and rise, live, in a little over an hour, just like the ISS astronauts do fifteen times every day.

(Okay, I cheated. That last image isn’t from HDEV.)

The Odd Trio

Cassini brings us an image of three of Saturn’s moons seen through its majestic rings. (The third moon, Prometheus, can be seen in the F ring on the lower left.)


Resupply at the Speed of Light

A little while ago, NASA emailed a wrench to the ISS. In other words, we are beaming stuff into space from the comfort of a desk, no rockets necessary.

What a brilliant use of technology.

Imagine sending a colony on Mars supplies not by physical transport, but by radio waves, and in a few minutes rather than half a year (provided the colonists have the materials.)
