This image may be the first look at exomoons in the making
These observations offer some of the best evidence yet that planets around other stars have moons, or exomoons.

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.

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.
- Space
The Milky Way’s ‘yellowballs’ are clusters of baby stars
The mysterious cosmic objects — first spotted by citizen scientists — turn out to be infant stars of various masses.

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.

Signs of a hidden Planet Nine in our solar system may be an illusion
Hints of the remote planet, also called Planet X, relied on clumped up orbits of bodies beyond Neptune. A new study suggests that clumping doesn’t exist.

Let’s learn about the moon
The moon is Earth’s nearest neighbor, and its gravity helps stabilize the planet’s climate and creates the tides.

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.
