“It is by going down into the abyss that we recover the treasures of life. Where you stumble, there lies your treasure.” -Joseph Campbell Ever since we created a question/suggestion box here, we’ve been deluged by far more excellent questions than one person could possibly answer, but that doesn’t mean we aren’t trying! For this…

“The proverb warns that ‘You should not bite the hand that feeds you.’ But maybe you should, if it prevents you from feeding yourself.” -Thomas Szasz But on this Messier Monday, you’re lucky enough that you’re about to be introduced to one of the great northern galaxies of the Messier catalogue that is feeding itself! There…

“Dream no small dreams, for they have no power to move the hearts of men.” -Johann Wolfgang von Goethe Welcome back to yet another Messier Monday here on Starts With A Bang! Each Monday, we highlight one of the 110 deep-sky objects that make up the Messier catalogue, showing you where and how to find…

“You wait for a gem in an endless sea of blah.” -Lawrence Grossman On the one hand, we have General Relativity, our theory of space, time, and gravity. It describes the Universe on both large and small scales perfectly, from the hot Big Bang to our cold accelerating expansion, from vast superclusters of galaxies down…

How can we see black holes?

“According to the special theory of relativity nothing can travel faster than light, so that if light cannot escape, nothing else can either. The result would be a black hole: a region of space-time from which it is not possible to escape to infinity.” -Stephen Hawking You may have encountered objects that are the same…

“There is a single light of science, and to brighten it anywhere is to brighten it everywhere.” -Isaac Asimov One of the most spectacular and successful ideas of the 20th Century was Einstein’s General Relativity, or the idea that matter and energy determines the curvature of spacetime, and the curvature of spacetime in turn determines…

“Everyone must leave something behind when he dies, my grandfather said. A child or a book or a painting or a house or a wall built or a pair of shoes made. Or a garden planted. Something your hand touched some way so your soul has somewhere to go when you die, and when people…

A Little Baby… Supernova?

We know, more or less how supernovae work. We’ve seen them just hours after they first go off through telescopes and satellites. The Crab Nebula, also known as M1, was a supernova that went off nearly 1,000 years ago in our own galaxy, for example, and we can simulate pretty well that it formed like…

Carnival Of Space: Movie Edition

The one-year anniversary edition of the Carnival of Space is up at Why Homeschool? If only more homeschoolers were into space, Astronomy, and science in general, the United States would be a far superior place, I’m sure! Thanks to Henry Cate for starting the Carnival and coming back to host it one year later! My…

Black Hole Kicked Out of Galaxy

No, not because it was too young to drink! Scientists at the Max Planck Institute for Extraterrestrial Physics were looking at some X-ray objects, and discovered something really weird: a very bright X-ray source moving out of a galaxy at nearly 3,000 kilometers/second! This thing is a goner. If our Sun were moving at even…
