There are less than 48 hours for most U.S. residents to submit congressional spending requests to their House representative.

Support NASA Science and submit a request! Our handy online guide will walk you through the process: dashboards.planetary.org/appropriations-guide

This image is from a video by YouTube user Hazegrayart posted four years ago. I don't know how big near-Earth asteroid 2024 YR4’s impact would have been had it hit the Moon. The point is that we're not gonna see something slam into our satellite and that disappoints me.

I don't know how big this rock is, so I've guessed at its scale. But it's probably *around* this size.

I thought Romulus was great! Tied for #3 with Alien³ (after Alien and Aliens, although I don't know how I'd order those two).
