A fast-moving star, possibly with an exoplanet, has been detected in the Milky Way, challenging current astrophysical models.

Hawkins and his colleagues tasked the algorithm to sort nearly 100,000 white dwarfs cataloged by the Milky Way-mapping Gaia telescope and find the polluted ones. The algorithm isolated 375 stars ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

Our solar system resides in a galaxy called the Milky Way, stuffed with between 100 billion and 400 billion other stars, many of them with planets of their own Every star that you see in the sky ...

Every single star you can see is part of the Milky Way, but we’re talking here about seeing the densest part—that diffuse, “milky” glow of billions of stars. Our satellite is the biggest ...

Scientists discovered the star SMSS1605-1443 in 2018. Upon discovery, they determined that it was perhaps one of the Milky Way’s oldest stars based on its chemical composition. However ...
