A black hole is more than just a region of space where nothing escapes. It can also become a powerful cosmic engine.

With the federal government cutting funds for research, scientific organizations are facing a budget crunch. This includes ...

Astronomers now believe the Milky Way’s “inevitable” collision with a neighboring galaxy is much less likely than originally thought.

The Milky Way may merge with the Large Magellanic Cloud in 2 billion years, not Andromeda, contrary to previous findings.

Earth’s violent collision with a protoplanet may have given birth to the Moon. Discover the giant-impact theory and the ...

“We saw that some rotational quantum states were somewhat weakly populated by the collisions while other states that were superficially very similar (that is, with the same energy and same angular ...

So, after the stick recoils from the ball impact, it clearly has angular momentum, since it's rotating. But what about before the collision? The stick isn't rotating and doesn't have angular ...

The Mustang driver tried to flee the scene of a collision, but was arrested; and police say alcohol was involved. On Friday at 8:17 p.m., the Rialto Police Department received a report of a ...

especially when considering atomic hyperfine structure—small energy shifts resulting from the coupling between an atom’s nuclear spin and angular momentum from the atom’s electrons. The basic model ...
