Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

In just over 10 hours of test observations, the Vera C. Rubin Observatory captured millions of celestial objects, opening the ...

New measurements of the universe’s expansion using James Webb Space Telescope appear to resolve the Hubble constant conflict ...

Astronomers studied 10,000 stars in Hubble pictures to make this composite image and to learn about the evolution of the Milky Way galaxy. Light from our own galaxy is the most recently produced ...

Scientists using NASA’s Hubble Space Telescope set out to study how Uranus’s magnetic field interacts with its largest moons—but instead, they stumbled upon a surprising discovery. They ...

This stunning Hubble image of IC 758 shows a peaceful spiral galaxy with soft blue arms and a glowing core—but beneath its calm appearance lies the remnant of SN 1999bg, a massive star’s explosive ...

Historically, the Hubble constant was introduced by Edwin Hubble in 1929, marking a major breakthrough in our understanding of the expanding Universe. Since then, refining its value has become a ...
