Telescopes peering back in time to less than a billion years after the Big Bang have spotted individual galaxies with dust that weighs
hundreds of millions of times as much as the sun.
That's
hundreds of millions of times as much as the bomb dropped on Hiroshima in 1945 and roughly 163,000 times as much as the Soviet Union's test of Tsar Bomba on October 30, 1961.
Hundreds of millions of times every year many of us turn to a new kind of online software called symptom checkers to try to self - diagnose our symptoms and to get advice on whether we should seek further medical care or just rest at home until we feel better.
