It’s a mystery that’s puzzled astronomers for years. Which came first, supermassive black holes or the galaxies that surround them? The post Supermassive Black Holes or Their Galaxies? Which Came First? appeared first on Universe Today.

All stars die, some more violently than others. Once our own Sun has consumed all the hydrogen fuel in its core, it too will reach the end of its life. Astronomers estimate this to be a short 7 billion years from now. For a few million years, it will expand into a red giant, puffing … […]

For the first time, astronomers are able to accurately simulate galaxies from shortly after the big bang to today by including a realistic treatment of the effects stars have on their host galaxies. For the past few decades astronomers have simulated galaxies by mixing the basic physical […]

Take a look around the Moon… no, really, take a good look AROUND the Moon! This is a fantastic animation of our planetary partner in space made by the folks on the Lunar Reconnaissance Orbiter team at Arizona State University. Assembled from reflectance maps and digital terrain models […]

We’ve got two new podcasts from the Astronomy Cast team of Dr. Pamela Gay and Fraser Cain: Ep. 313: Precession, and Episode 314: Acceleration. 313: Precession The Earth is wobbling on its axis like a top. You can’t feel it, but it’s happening. And over long periods of time, these […]

What’s new in the outer reaches of our solar system? Try the discovery of a Trojan asteroid orbiting Uranus. While a plethora of puns exist for this simple fact, the reality check is that this means there are far more of these objects out there than astronomers expected. The new Trojan even […]

Why don’t we have insects the size of horses? Why do bubbles form spheres? Why does it take so much energy to broadcast to every star? Let’s take a look at some non-linear mathematical relationships and see how they impact your day-to-day life. Click here to download the episode. Or […]

Are you ready for a new galactic puzzle? Then let’s start with some clues. It has been long assumed that some galaxies reach a point in their evolution when star formation stops. In the distant past, these saturated galaxies appeared smaller than those formed more recently. This is what […]
