Gaia was able to pin down 20 times the number of stars captured by ESA's Hipparcos satellite.
Astronomers have created a detailed computer simulation of the Milky Way galaxy’s formation, which solved the mystery involving the missing group of smaller galaxies that should have been present.
Astronomers discover two distinct types of star in the stellay cluster Terzan 5 that have an age-gap about 7 billion years.
At the center of the Milky Way galaxy is a dormant, supermassive black hole. But a new study suggests that the galaxy's core had once been ablaze six million years ago.
Young stars are mysteriously disappearing from the Milky Way, according to recent reports. While there are an abundance of old stars, young stars called Cepheid Variable stars found at the center of the Milky Way galaxy have gone missing.

A planetary scientist explains that, with some adaptations, life-forms similar to Earth's could live on other planets' environments as well.
A new planet has been detected by the Gemini Planet Imager, and it is like a younger form of Jupiter, researchers say.
Scientists have discovered a gas planet located deep within our galaxy - about 13,000 light-years away - making it one of the most distant planets known, according to new research.
Billions of years ago, the Milky Way galaxy was churning out stars at an amazing rate, in what scientists are calling a stellar "baby boom." Now new research shows that our own Sun was a late "boomer" to the party.
