Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.
Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.
A new image captured by the Very Large Telescope reveals stars and gas orbiting the "invisible giant" at the heart of our galaxy.

There's a whole slew of objects that astronomers aren't sure whether to classify as "failed stars" or "overgrown planets."
One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.
The observations offer a rare glimpse into our solar system's early history.
Two aging stars in the binary system AFGL 4106 sculpt a glowing, egg-shaped nebula as they approach the end of their lives.
Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron star-powered pulsar.
An organic molecule called methanimine was found scattered throughout a dense clump of gas and dust 554 light-years away.
