This means that the climate on Mars might be much more dynamic than previously believed. Perhaps the climate could change again. And liquid water underneath these [...]
Magnetic Fields Shape the Jets Pouring Out of Supermassive Black Holes
The cores of galaxies contain supermassive black holes, containing hundreds of millions of times the mass of Sun. As matter falls in, it chokes up, forming a super hot accretion disk around the black hole. From this extreme environment, the black hole-powered region spews out powerful jets of particles moving at the speed of light. [...]

Our senses can only detect a fraction of the phenomena happening in the Universe. That's why scientists and engineers develop detectors, to let us see radiation and particles that we could never detect with our eyes and ears. This week we'll go through them all, so you can understand how we see what we can't [...]
