An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.
You're about to take a dip into the inky blackness of a giant black hole and see what's on the other side of that enigmatic event horizon. What will you find inside? Read on, brave explorer.
Two legendary scientists gave us an understanding of gravity, and how to apply that understanding to the motion of the sun, planets and moons.
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?
Physicists have figured out what's lurking inside of white dwarfs, revealing the stellar corpses are creamy and filled with exotic quantum liquids.
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.
Physicists are scouring the universe for evidence that one of the fundamental constants of nature, Newton's gravity, is not constant at all.
Is it a wave, or is it a particle? This seems like a very simple question — except when it isn't. And it isn't in one of the most important aspects of our universe: the subatomic world.
Obviously, some chain of unfortunate events led to the ejection of 'Oumuamua from its home system. But what could possibly cause such a catastrophe?
Physicists have proposed that a trio of particles called Higgs bosons could be responsible for the mysterious vanishing act of antimatter in the universe.
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.
Physicists on the hunt for the invisible hand that shapes our universe and the galaxies within it have turned their gaze to the dark side.
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.
