Two legendary scientists gave us an understanding of gravity, and how to apply that understanding to the motion of the sun, planets and moons.
Paul M. Sutter is a theoretical cosmologist at the Institute for Advanced Computational Science at Stony Brook University and a guest researcher at the Flatiron Institute in New York City. An award-winning science communicator, he is the author of Your Place in the Universe and How to Die in Space, and the host of the "Ask a Spaceman" podcast.
A brand-new particle has possibly emerged and is altering the future destiny of our entire cosmos, a physicist says.
Different measurements of the universe's expansion yield different results. Are we getting something wrong, or do we need brand-new physics to figure it out?
You might not recognize Peebles' name, but he theorized the existence of dark matter and has been a key player in painting the portrait of the universe that we now understand.
The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.
Obviously, some chain of unfortunate events led to the ejection of 'Oumuamua from its home system. But what could possibly cause such a catastrophe?
There are some odd little particles out there that are bound by the strong nuclear force, but physicists can barely get a glimpse of them before they flit out of existence.
A giant linear collider the size of Manhattan could finally help us find new physics, scientists argue.
Our lives here on Earth are small and insignificant and inconsequential — but only in a certain frame of reference, and that frame of reference doesn't necessarily apply to cosmic scales.
Moons of "hot Jupiter" alien worlds may detach from their parent planets and begin orbiting stars on their own.
Astrophysicist Paul Sutter breaks down the science behind NASA's historic Apollo moon missions for Space.com. Tune in here!
The universe really likes its information — but black holes pose a huge paradox physicists can't yet solve.
