“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…

“I didn’t even know there were stars to look at to not see. If you don’t know that they’re there, you don’t know that you’re missing them.” -Neil deGrasse Tyson, on light pollution As with pretty much every week that goes by, we’ve had a slew of fantastic stories here at Starts With A Bang! There have…

“The history of astronomy is a history of receding horizons.” -Edwin Hubble As you look to greater and greater distances, you’re looking back in time in the Universe. But thanks to dark energy, what we can see and access today isn’t always going to be accessible. As galaxies grow more distant with the accelerated expansion…

Earlier this month, news broke of a study that found potentially health-harming chemicals in a variety of fast food packaging. Upon hearing such news, the natural inclination is to worry that you’re ingesting those chemicals along with your burger and fries. Study researcher Graham Peaslee says that’s certainly a risk. But perhaps the greater risk, he says, happens after that hamburger wrapper ends up in landfill and the chemicals seep into our environment and water.

“It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of forces.” -Stephen Hawking Galaxies don’t just exist in isolation in our Universe, but are often found bound together as a part of even grander structures. Our own Milky Way is bound in a…

“When Benjamin Franklin inveted the lightning rod, the clergy, both in England and America, with enthusiastic support of George III, condemned it as an impious attempt to defeat the will of God.” -Bertrand Russell You’ll often hear charges that science has become too politicized, but it’s the other way around. Science is our best way…

Earth like exoplanet story telling

As more and more exoplanets (at first) and earth-like exoplanets (eventually) have been discovered, the way thy are described to us has become increasingly sophisticated. Below are embeds of diverse video descriptions that have been very quickly developed and distributed given the freshness of this latest scientific discovery. Note that the practice of very clearly…

“It isn’t only the beauty of the night sky that thrills me. It’s the sense I have that some of those points of light are the home stars of beings not so different from us, daily cares and all. who look across space with wonder, just as we do.” -Frank Drake What is it that…

“Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment we watched the stars. There were practical calendar reasons of course but there was more to it than that. Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling…

“We think we’ve come so far. Torture of heretics, burning of witches, is all ancient history. Then, before you can blink an eye, suddenly, it threatens to start all over again.” -Captain Picard It’s been another remarkable week here at Starts With A Bang! Of course there’s been news, science, physics and astronomy galore, but the biggest…
