This Aurora Photo Is one of the most Insane I’ve Ever Seen [Astronomy]

This Aurora Photo Is one of the most Insane Ive Ever Seen [Astronomy] By far, it truly is essentially the mostsome of the most spectacular and insane photography of an aurora borealis I’ve ever seen. Once I showed this in our virtual bullpen, the unanimous reaction was complete awe.

Auroras emit light due to the emission of photons by oxygen and nitrogen atoms within the upper atmosphere. Those atoms get excited-or ionized-by the collision with solar wind particles, which might be accelerated by the Earth’s magnetic field. As the atoms get excited or return to their normal state, they emit visible energy. When it really is an oxygen atom, the light emitted is either green or brownish-red, reckoning on the energy level absorbed by the molecule. Blue happens when nitrogen gets ionized, and red when it returns to ground state.

It was photographed by Ole Christian Salomonsen over Tromsø, Norway, using long exposure. That’s why you will see streaks from satellites and an airplane crossing the firmament.

    Sick and bored with your boring old truss? This useful little robot might be just the answer you are looking for. It might navigate a truss structure using its 3D-printed bi-directional gear innards, unscrew a beam with its rotational mechanism and reattach it, transforming the structure right into a new shape. The structure itself is specially designed for the bot, with robot lockable… »
