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.

Scientists discover likely source of the moon’s faint yellow tail
These sodium atoms are part of the debris kicked up from the moon’s surface, mostly by micrometeorites, two new studies conclude.

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.

Extreme pressure? Diamonds can take it
Diamond retains its structure even at extreme pressures, which could reveal how carbon behaves in the cores of some exoplanets.

Exploding neutron star proves to be energy standout of the cosmos
This is what scientists had suspected. But until one showed up outside our galaxy, they couldn’t be sure. Now they are.

Our feverish universe is getting hotter every day
For the first time, astronomers have taken the temperature of the cosmos at different times in its history. Galaxy clusters are cranking up the heat.

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.”

Jupiter may have ‘sprites’ or ‘elves’ in its atmosphere
This is the first time that scientists have seen hints of these weird side effects of lightning storms somewhere other than on Earth.
