the sun erupted late on Jan. 22, 2012 with an earth-directed coronal mass ejection (CME) and a burst of fast moving, highly energetic protons.
The coronal mass ejection collided with Earth’s magnetic field a little after 10 a.m. on Jan. 24, 2012.

Venus orbits closer to the Sun than the Earth does, and on rare occasions our orbits align such that Venus passes directly in front of the Sun.
The Sun looks like a boiling cauldron with Venus silhouetted against it. The ring around the planet is from Venus’s thick atmosphere, scattering and bending the sunlight coming through from the other side.

The Moon’s current orbital distance, about thirty times the diameter of the Earth, causes it to appear the same size in the sky as the Sun, allowing it to cover the Sun precisely in total solar eclipses.
Now, that’s FUCKING amazing, right?

Flux Ropes on the Sun
This is an image of magnetic loops on the sun, captured by NASA’s Solar Dynamics Observatory (SDO). It has been processed to highlight the edges of each loop to make the structure more clear.

French astronomers think they found Tatooine in real life and we didn’t even have to travel to a galaxy far, far away (well, it’s still kind of far). The fictional home of Luke Skywalker is called 2MASS0103(AB)b in real life and it revolves around two suns that move relatively close together. Basically, this planet is in the binary star system just like Tatooine.
