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 ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

Astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere report the discovery of a new brown ...

Blue straggler stars are the weird grandparents of the galaxy: They should be old, but they act young. Finding and studying these strange stars helps us understand the complicated life cycles of ...

The Sun's transition from the main sequence to the red giant phase is a gradual process, spanning approximately a billion years. This transition begins with a subgiant phase where core hydrogen fusion ...

Our Sun is about halfway through its life, which means Earth is as well. After a star exhausts its hydrogen nuclear fuel, its ...

The latest image from the Hubble Space Telescope turns a quiet patch of sky into a spectral scene, revealing a so‑called ...
