Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

NASA’s Hubble Space Telescope captured images of Lupus 3, showing T Tauri stars and gas-dust regions, providing data on early ...

New research explains how dust links the formation, evolution, and fate of stars and planets, and why future telescopes are needed to observe these processes in detail ...

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It’s so well understood that ...

The sun is not only our closest stellar neighbor, it's also the star we understand the most. As we've observed it over the centuries, we've learned that the sun is not an immortal constant. It goes ...

This image from the ALMA telescope shows star system HD101584 and the complex gas clouds surrounding the binary. It is the result of a pair of stars sharing a common outer layer during their last ...
