The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

Scientists used new data taken by the James Webb Space Telescope to make a new reading of the rate at which the universe is expanding over time, by measuring light from 10 galaxies including the one ...

Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

Explore 15 photos and facts about the Hubble Telescope, revealing its discoveries, missions, and breathtaking views of space.

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight Center. Credit: NASA's Goddard Space Flight Center Producer & Director: James ...

To turn that distance into a Hubble constant, you also need the event’s redshift, which is tied to how fast the source is receding due to cosmic expansion. Standard approaches get the redshift by ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...

Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one ...

NASA’s Hubble Space Telescope made fresh observations of the Crab Nebula 25 years after it observed the supernova remnant for the first time. Revisiting the supernova remnant revealed that it’s still ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...
