Exoplanets need right stuff to be habitable
The elemental makeup of a star can reveal whether planets in its solar system could support sustained plate tectonics, a requirement for Earth-like life, researchers propose.

Pulsar pair ripples spacetime
A pair of pulsars gives scientists the best evidence so far for gravitational waves, which have yet to be detected directly.

General relativity caught in action around black hole
X-rays enable scientists to spot a black hole twisting the surrounding fabric of spacetime, just as Einstein’s theory predicts.

Debate grows over whether X-rays are a sign of dark matter
The dwarf galaxy Draco, which is chock-full of dark matter, doesn’t emit a band of X-rays that researchers hoped were produced by the mysterious invisible stuff.

It’s a new planet! It’s an unknown star! It’s — oops!
A couple of unexpected wandering points of light in the sky could be new planets or even a dim star orbiting the sun, but researchers have plenty of reasons to be skeptical.
