Researchers created a technique to reduce uncertainty in cosmic birefringence measurements, resolving a key phase ambiguity and improving future studies of fundamental physics.

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising ...

The Sun, along with more than 1,500 other stars, journeyed from the middle of the Milky Way to its current position a few billion years ago.

Our Sun is actually a cosmic refugee. Around 4.6 billion years ago, it first ignited in a hostile, radiation-blasted neighborhood 10,000 light-years closer to the Milky Way’s center than it is now.

An international research team has found that the Milky Way and its galactic neighbors appear to sit inside a vast, flat concentration of dark matter, a structure stretching roughly 10 megaparsecs and ...

Our sun was born 4.6 billion years ago near the crowded center of the Milky Way and then migrated roughly 10,000 light-years outward to the peaceful galactic suburbs it currently occupies. Now a pair ...

The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 billion years the age of the universe.

The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more ...

MOTHRA observing at night. Each mount is equipped with a wide area web cam. Besides the mount in the foreground two others are visible. The skies at El Sauce Observatory in Chile ...

New research suggests our Sun was part of a huge migration of Sun-like stars that moved away from the Milky Way’s center billions of years ago.

A supernova, the explosive end of a massive star's life cycle, is among the brightest phenomena in the universe—typically ...
