The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

Astronomers detect signs of a massive, invisible black hole in the Large Magellanic Cloud, which may collide with the Milky ...

In 2011, a project that surveyed the Milky Way galaxy for exoplanets — which are planets beyond our solar system — spotted an ...

Astronomers have found a supermassive black hole in the Large Magellanic Cloud. This black hole is 600,000 times the mass of ...

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from the new galaxy.

NASA said the system is thought to be moving at least 1.2 million miler per hour, nearly twice as fast as our solar system.

ASTRONOMERS may have just found the fastest exoplanet system in the galaxy – a super-Neptune world orbiting a hypervelocity ...

A Milky Way collision with a supermassive black hole might be closer than we thought. Hidden deep in the Large Magellanic ...

when researchers precisely measured the motions of many stars within the Andromeda Galaxy and found that these stars were approaching the Milky Way. Presently, the two galaxies are moving toward ...

How fast can solar systems orbit our Milky Way Galaxy? This is what a recent study published in The Astronomical Journal hopes to address as an internation | Space ...
