Astronomers at NASA have caught a glimpse of a star system whipping through space at an unprecedented speed. While the system ...

"If so, it will be the first planet ever found orbiting a hypervelocity star." A hypervelocity star is an ultra-fast star that researchers believe has brushed past the supermassive black hole at ...

It was, of course, a great joy for me when we could confirm the planet’s existence,” said Dr. Cretignier. “It was also a ...

Astronomers at the NASA Goddard Space Flight Center may have discovered a star hurtling through the Milky Way with a planet ...

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 ...

Since the star is so feeble, that's well outside its habitable zone. "If so, it will be the first planet ever found orbiting a hypervelocity star." A paper describing the results, led by Terry ...

Astronomers have discovered a fast-moving star potentially carrying a planet across space at 1.2 million miles per hour, ...

Since the discovery of the first planet outside the solar system in the mid-1990s, the catalog of extrasolar planets, or "exoplanets," has grown to over 5,000 entries. Many of these exoplanets are ...
