Edwin Hubble

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

Building an observatory on the Moon would be a huge challenge—but it would be worth it.

A century ago, the American astronomer Edwin Hubble first established that this so-called 'spiral nebula' was approximately 2.5 million light years away from our Milky Way Galaxy.

Astronomers have created the largest photomosaic of the Andromeda galaxy yet using Hubble data. The image helps trace the hidden history of Andromeda. The post Andromeda galaxy: Hubble's largest photomosaic yet first appeared on EarthSky.

Our model says one thing; our observations say another.

Using the Gemini Multi-Object Spectrograph (GMOS) on the Gemini North telescope at NSF's International Gemini Observatory, operated by NOIRLab, astronomers have captured a stunning image of NGC 1270 and several other galaxies in the central region of the enormous Perseus galaxy cluster.

This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million

Just 13.8 billion years after the hot Big Bang, we can see objects up to 46.1 billion light-years away. No, this doesn't violate relativity.

In all of physics, some of the most important properties inherent to the Universe itself are constants of nature. The speed of light in a vacuum, the strength of the gravitational force between two…

First results from the Dark Energy Spectroscopic Instrument offer hints of new physics.

New theoretical research suggests that a mysterious form of matter called "unparticles" could be the driving force behind the expansion of the universe.

The MIT Press announced recipients of 2024 Grant Program for Diverse Voices, including new books from Kimberly Juanita Brown, Michel DeGraff, Amanda K. Greene, Silas Munro, and Anna Von Mertens.

The discovery after its launch that the Hubble Space Telescope's primary mirror suffered from a flaw disappointed scientists who could not obtain the sharp

If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of star formation.

The most important things we know about the cosmos were discovered in the mountains above Los Angeles. 'You don't just throw away a historic place,' says one of the volunteers trying to save it.

The European Space Agency's Euclid space telescope is set to launch Saturday on a six-year journey to investigate the mysteries of the "dark side" of the...

With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.

The anti-gravity force that is driving the accelerating expansion of the universe appears to be distributed uniformly across space and time.

The famous first image of a black hole just got two times sharper. A research team used artificial intelligence to dramatically improve upon its first image from 2019, which now shows the black hole at the center of the M87 galaxy as darker and bigger than the first image depicted.

For centuries, scientific discoveries have suggested humanity occupies no privileged place in the universe. Now, however, studies of worlds beyond our solar system could place meaningful new limits on our existential mediocrity
