discuss all space related topics here.

let's start with this new one that popped up on the NASA website.

so apparently when the hubble takes deep field images something interesting shows up sometimes.




those curvy lines are asteroid trails, they show up due to the long exposures needed for photographing distant galaxies.

the shape is because of Hubble's orbit around earth, many of these distant space rocks were too faint to be discovered otherwise.

"Astronomers found a unique asteroid for every 10 to 20 hours of exposure time." - NASA


this is part of the mission of the frontier fields program.
