“When a massive star explodes at the end of its life, the explosion dispenses different elements-helium, carbon, oxygen, iron, nickel-across the universe, scattering stardust. That stardust now makes up the planets, including ours.” -Michelle Cuevas Every once in a while, a new light appears somewhere in the night sky: the result of a massive star…

“The origin and evolution of life are connected in the most intimate way with the origin and evolution of the stars.” -Carl Sagan The Crab Nebula is one of the most interesting and compelling objects in the entire night sky. In the year 1054, a supernova went off in the constellation of Taurus, where it…

“Without these supernova explosions, there are no mist-covered swamps, computer chips, trilobites, Mozart or the tears of a little girl. Without exploding stars, perhaps there could be a heaven, but there is certainly no Earth.” -Clifford A. Pickover One of the most sobering cosmic truths is that every star in the Universe will someday run…

“When a star goes supernova, the explosion emits enough light to overshadow an entire solar system, even a galaxy. Such explosions can set off the creation of new stars.” -Todd Nelsen In February of 1987, the first light from a supernova some 168,000 light years away was observed on Earth. It became the closest supernova…

“Even with all the collected data we cannot say with 100% certainty that the ASASSN-15lh event was a tidal disruption event. But it is by far the most likely explanation.” -Giorgos Leloudas Last year, a record-shattering event occurred: we saw the brightest supernova ever observed in the Universe. It outshone the previous record holder by…

“When we recall the past, we usually find that it is the simplest things – not the great occasions – that in retrospect give off the greatest glow of happiness.” -Bob Hope When a very massive star reaches the end of its life, it runs out of burnable fuel. As a result, the core collapses,…

“Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my luck and instead will spend my life trying to find flaws in this understanding – such is the role of a scientist.” -Brian Schmidt Just a few days ago, a new paper was published in…

“My eureka moment was in the dead of night, the early hours of the morning, on a cold, cold night, and my feet were so cold, they were aching. But when the result poured out of the charts, you just forget all that. You realize instantly how significant this is—what it is you’ve really landed…

“When a star goes supernova, the explosion emits enough light to overshadow an entire solar system, even a galaxy. Such explosions can set off the creation of new stars. In its own way, it was not unlike being born.” -Todd Nelsen The vast majority of elements beyond hydrogen found on Earth were created inside a…

“If I can’t make it through one door, I’ll go through another door – or I’ll make a door. Something terrific will come no matter how dark the present.” -Rabindranath Tagore Time continues marching on here at Starts With A Bang, just as it does everywhere. My Patreon supporters have stepped up their game, and we’re just…
