In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...

Hubble’s updated view of NGC 3370, richer in light and detail than ever before, deepens our understanding of both the galaxy and the cosmos itself. This new Hubble Picture of the Week highlights a ...

Dark-energy evidence suggests the universe will end in a “big crunch” roughly 20 billion years from now. The universe is nearing the halfway point of what may be a 33-billion-year lifespan, according ...

Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth -- raising tricky questions about theories of the ...

In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of ...

A more precise distance to the Coma galaxy cluster was measured. This measurement increases the discrepancy between observed and predicted universe expansion rates. The discrepancy, called the Hubble ...

With all the technological marvels we have today, it is tempting to think that we have all the answers. However, the reality of the situation is far different: many of the fundamental questions about ...

This NASA/ESA Hubble Space Telescope image features the spiral galaxy Messier 77, also known as the Squid Galaxy. Everything on Earth, in our solar system, our galaxy, and beyond is contained within ...

How fast is the universe expanding? This is what a recent study published in The Astrophysical Journal hopes to address as a team of scientists investigated to see if what’s known as the Standard ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...
