Video: What superpower would you want to have? The ability to fly? Teleport? Turn invisible? Time travel? Heal? What about to ability to see the invisible? Not exactly the flashiest power you can have especially because we can kind of, sort of, do that right now. This lovely animation explainer from Amaël Isnard shows how though we can't see magnetic forces in action, we at least get to see the auroras in the north and south poles, which reveal the invisible magnetic field of Earth.

Video: A "rather faint" coronal mass ejection from the Sun last Thursday arrived at Earth over the weekend, and brought with it a proton arc — an especially rare bright display of the Aurora Australis, the ethereal lights in the sky over extreme southern latitudes of Australia and the Antarctic continent.
The aurora borealis that took place on St. Patrick's day was spectacular, but aside from being the strongest geomagnetic storm in a decade, there's another reason it was special. It was the first time that thousands of citizen scientists tweeted about the aurora to help NASA construct a detailed global map of the event.
Visiting the Northern Lights is a dream many of us share, but the distance between Australia and the top of the world puts it out of reach for most. Thankfully, the Sun has our best interests at heart, and blasted charged particles our way so Australia and New Zealand could view the lights. The videos are pretty spectacular.
Video: I would never get tired of looking through the cupola of the International Space Station, which is how I imagine Darth Vader's Death Star bedroom window. Astronaut/Captain America Reid Wiseman used it to record this great clip of an aurora. It makes Earth look like a magic green marble — or a palantir.
Briefly: A long exposure photo by masterful Swedish astrophotographer Göran Strand is featured once again on NASA's Astronomy Picture of the Day: Double aurora ovals — green and violet — over the town of Östersund, Sweden, with the Milky Way covering the entire sky. What an awesome world we live in.
A massive solar storm in July 2012 was more intense than thought — and it blasted right through the Earth's orbit. Luckily for us, we were on the other side of the sun, thus missing the chaos completely. But if that storm had hit this beautiful little blue marble in space? "The solar bursts would have enveloped Earth in magnetic fireworks matching the largest magnetic storm ever reported on Earth, the so-called Carrington event of 1859," Science Daily reports.
