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 ...
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 ...
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 ...
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 ...
The Hubble Space Telescope has delivered a stunning new perspective on one of the most famous quasars in the cosmos, 3C 273, ...
Observe paired the funding news with the launch of Hubble, the San Mateo, Calif.-based startup’s latest product for storing, managing and analyzing machine-generated data. The new offering ...
Astronomers, leveraging the unique capabilities of NASA’s Hubble Space Telescope, have been able to see further than ever ...
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 ...
NASA's Hubble Space Telescope explores the evolution of spiral galaxy UGC 10043 through images taken 23 years apart, in 2000 ...
In other words, the universe must be expanding. He announced his finding in 1929. The ratio of distance to redshift was 170 kilometers/second per light year of distance, now called Hubble's constant.
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 ...
At the time, Hubble represented the state of the art in imaging the universe, and the photograph a prime example of Hubble’s ...
