Solar Flare Bursts Into Fiery Rain Over The Sun

On the 19th of July a solar flare burst from the surface of the sun. Instead of dispersing, the hot plasma became trapped in the magnetic field emanating from the region of the eruption. Normally invisible to the naked eye, the lines of the magnetic field lit up as it captured the flare and forced it back down to the solar surface in a dazzling phenomenon known as a coronal rain.

The phrase “Earth to scale” is never really used in any non-terrifying context.

10 Moons Every Person Should Know

Pretty much everyone can rattle off the names of our solar system’s eight (formerly nine) planets, but ask the average person to list some moons and you’ll be lucky if they can tell you more than two or three.

Now, you obviously can’t expect people to remember the name of every single satellite in the solar system (after all, they outnumber the planets by around 20 to 1), but if you have even the slightest interest in astronomy, it wouldn’t kill you to be familiar with at least an even ten. So with that in mind, we’ve assembled this reference guide to ten of the solar system’s most noteworthy moons.
