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.
The ratio of a star’s age to its metal content ties it to a characteristic birthplace within the disk.
The Sun may have been part of a small group of stars that migrated from the core of our galaxy between 4 and 6 billion years ago.
For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or “wave,” of stars drifting out from the inner parts of the Milky Way. This ...
Now a pair of studies published today in Astronomy and Astrophysics argue that the sun did not make this journey alone. The telltale sign of the sun’s galactic journey is its chemical composition, ...
Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long ...
Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their ...
