James Webb telescope helped solve a decade-long mystery about the universe’s expansion rate, shedding new light on the cosmic ...

This breakthrough sheds new light on how the radioactive isotope lead-205 (²⁰⁵Pb) is formed in asymptotic giant branch (AGB) stars and helps refine estimates of the Sun’s formation timeline. Their ...

Astronomers now use two other types of stars besides the Cepheids (known as the Tip of the Red Giant Branch stars (TRGB) and the J-region Asymptotic Giant Branch (JAGB) stars). But while one group ...

Frustratingly, this hasn’t yet happened. Astronomers now use two other types of stars besides the Cepheids (known as the Tip of the Red Giant Branch stars (TRGB) and the J-region Asymptotic Giant ...

carbon-rich giant stars that belong to what’s called the J-region asymptotic giant branch (JAGB). These stars also sit away from a galaxy’s bright disk and emit a lot of infrared light.

New James Webb Space Telescope results have revealed that there may not be a Hubble tension after all. But contradictions within the findings point to a deeper mystery. When you purchase through ...
