For all the biological activity on our homeworld, we're not the only interesting planet orbiting the sun. There are some other equally amazing places in the solar system. Here is just a sampling.
Paul Sutter received his Ph.D. in Physics from the University of Illinois at Urbana-Champaign in 2011. After spending three years at the Paris Institute of Astrophysics, he is now a visiting scholar at the Ohio State University's Center for Cosmology and Astro-Particle Physics. Sutter is the host of several podcasts and YouTube series, consults for TV and film productions, and frequently makes public appearances discussing physics and astronomy topics and the role science plays in society.
Astronomers recently spotted perhaps the strangest white dwarf yet: a dead star the spins twice a second, sucking down material from a nearby companion as it goes.
Life on Earth can seem pretty hazardous, but if you ask astrophysicist Paul Sutter, it's still safer than anywhere else in the universe.
We all know and love the speed of light, but why does it have the value that it does? Why isn't it some other number? And why did it become such a cornerstone of physics?
A few scant equations can explain a variety of phenomena in our universe, over vast gulfs of space and time. Here's a taste of just how powerful modern physics can be.
There's a reason — actually, several — why Sir Isaac Newton is often considered the No. 1 scientist of all time.
For the past few years, the possibility of a new (and big!) planet hanging around in the far outer solar system has tantalized scientists and the public alike. Is "Planet Nine" out there or not?
Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO).
Magnetars — highly magnetized, rapidly rotating super-dense stars — are among the most enigmatic creatures to inhabit the cosmos and their origins are shrouded in mystery.
Is space-time ultimately smooth at the tiniest of scales, or something else? It seems impossible to measure, but researchers are beginning to look down. Deep down.
Although simulations suggest that black holes should grow quickly in the early universe, when astronomers look back in time they simply cannot find many such structures.
