A research team may have discovered a star with an exoplanet that is so fast that both will leave the Milky Way.

These are known as hypervelocity stars, with some moving faster than the escape velocity of the Milky Way of around 600 kilometers (373 miles) per second. There is another star that is almost as ...

A star system has been discovered to be moving at an estimated 1.2 million miles per hour, making it possibly the fastest moving solar system in our galaxy.

Since its launch in 2013, Gaia has been dedicated to creating an accurate three-dimensional map of the Milky Way. Using two high-precision optical telescopes, the spacecraft carefully records the ...

Astronomers may have found a star racing through our galaxy at an incredible speed—dragging a planet along with it! If ...

NASA scientists have made a groundbreaking discovery that could change how we understand the dynamics of exoplanetary systems ...

Astronomers have identified what they believe to be the largest structure in the universe to date. Named "Quipu" after the ancient Incan method of record-keeping, this colossal superstructure ...

The cosmic superstructure Quipu is more than 13,000 times the length of the Milky Way, and its mass is 200 quadrillion times ...

Enabled by supercomputing, University of Pretoria (UP) researchers have led an international team of astronomers that has ...
