Born in deep shadows? That could explain Jupiter’s strange makeup
Dust that blocked sunlight might have caused the gas giant to form in a deep freeze, a new study suggests.

Cosmic filaments may have the biggest spin in outer space
These rotating threads of dark matter and galaxies stretch millions of light-years. Scientists want to know how their spin begins.

Moon-sized white dwarf is the smallest ever found
This dead star is also spinning very fast and has an amazingly powerful magnetic field.

Spin in this Milky Way bar may show cosmic dark matter does exist
A method akin to studying a tree’s rings reveals the timeline of a slowdown in those stars at the heart of our Milky Way galaxy.

Huge arc of galaxies is surprising and puzzling cosmologists
The arc appears to violate a cosmic rule that on such large scales, matter will be evenly distributed.

Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.

The pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.

Here’s why people picked certain stars as constellations
Patterns of human eye movement help explain why particular sets of stars form iconic shapes, a high school student showed.

Ingenuity helicopter makes history by flying on Mars
The copter's 40-second-long flight in the Red Planet’s thin air is only the first in a planned series of daring flights.

Scientists Say: Planet
Planets have to orbit a star, be big enough to form a sphere and keep other objects out of their path around their star.

Rogue planets wander the galaxy all alone
Some planets don’t orbit stars. They were kicked into space long ago. The newest, smallest one found is only about as massive as Earth.

Meet ‘Pi’ — a new Earth-sized planet
Searching through data from NASA’s K2 Mission, researchers found a new planet. Some call it K2-315b, others smile and refer to it as “Pi Earth.”
