How far would you go to get a good photo?
Would you think of taking them from a slightly differnt angle? Would you think of leaning over a cliff? Or would you spend however many millions to put a 15 tonne telescope in the back of a 747?
This one works in the infra-red, which is a problem for ground-based telescopes because water vapour absorbs some of it – and it’s already found something nobody else has spotted. From the article above:
thanks to the vision of Sofia’s Forcast instrument, it has become clear that something else is shining bright in the region, deep in the infrared
They also snapped some photos of the Orion Nebula, and found an molecule made of just one atom each of hydrogen and sulphur – apparently, this doesn’t happen on Earth. Either way, try carrying that telescope around!
