If The Moon Were At The Same Distance As The ISS 

Examples of a Brocken Spectre, a phenomenon where a person’s giant shadow appears magnified onto clouds miles away. The shadow from the sun behind the person creates a halo, giving it an angelic appearance. This mostly occurs on any misty mountainsides or cloud banks, and can even be seen from aeroplanes.

Don’t try this at home!

I talked about the interesting structure of graphite (aka pencil lead) in our latest video:

But I didn’t have time to touch on one of the fascinating side effects of this structure - graphite’s conductivity. A single, two-dimensional sheet of graphite (known as graphene) is the most conductive material we know about. Diamond is among the least conductive materials we know about.

Impure graphite - like the stuff we find in pencils - is somewhere in between. It’s more conductive than sea water and less conductive than steel. As free electrons flow through it, it lights up like a filament and puts out a lot of heat.

Some risk-taking YouTubers (MausolfB Education and ElectroBoom) demonstrated this property so you don’t have to.

the new composite james webb image is so beautiful ive been staring at it for 10 minutes straight

featuring jupiters rings, amalthea (along with a bunch of other moons), the northern and southern auroras, and the great red spot

EDIT: FAQs answered here

no offense but all the pictures of the eclipse i've seen today are really boring here are the ones my astrophotographer boyfriend took

so international space station astronauts apparently dropped a tool bag during a spacewalk. and if you look outside when the ISS is in your region, you can see it with binoculars

The tool bag is now orbiting our planet just ahead of the ISS with a visual magnitude of around 6, according to EarthSky. That means it is slightly less bright than the ice giant Uranus, the seventh planet from the sun. As a result, the bag  —  officially known as a crew lock bag  —  is slightly too dim to be visible to the unaided eye, but skywatchers should be able to pick it up with binoculars.  To see it for yourself, first find out when you can find spot the space station over the next few months (NASA even has a new app to help you). The bag should be floating two to four minutes ahead of the station. As it descends rapidly, the bag is likely to disintegrate when it reaches an altitude of around 70 miles (113 kilometers) over Earth. 

she's fucking magnificent

Pulling apart duct tape causes chemical bonds to break which indirectly gives rise to a faint blue glow in an effect called triboluminescence 

The orbit of Jupiter protects the Earth from asteroids.
