Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an ...

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.

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.

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

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 ...

Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

Earth's orbit around the solar system is slightly elliptical so on one day each year it's closest to the Sun (shown here with a halo around it). For planet Earth and our star, the Sun, today is like ...
