Later the Belgian priest and physicist Georges Lemaître realized that the velocity-distance relationship measured by Hubble was evidence for the expansion of the Universe. Since the expansion of ...
The speeds of the farthest stars and galaxies that we can observe don’t match what the Hubble constant predicts. Because light from a distant object has traveled for billions of years to reach us, our ...
We showed in a 2020 paper that this could solve the Hubble tension and explain the galaxy number counts, provided our patch of the universe is about 20% less dense than average out to a billion ...
Hubble's images have helped to pin down the age of the universe, which the expansion rate of pulsating stars suggests is some 13 billion to 14 billion years. Hubble has also captured images of ...
New techniques are being used to transform images from the Hubble Space Telescope into spectacular 3D visualisations of the Universe. Today the Hubble Space Telescope - affectionately known as ...
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because ...
Legendary Active Galaxy Contains a Monster Black Hole Amateur astronomers can observe an extraordinary celestial object known as 3C 273, the most distant target visible through a standard backyard ...
Hubble’s longest looks into space have disclosed star-swarms 500,000,000 light-years away, and this appears to be the limit of Mt. Wilson’s giant telescope. Thus the observable universe is a ...
