For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the ...

As the Hubble Space Telescope celebrates 35 years in space, here's what to know about the ambitious instrument.

The reason for that is that a void -- with far more matter outside the void exerting a slightly larger gravitational pull -- will affect the Hubble Constant value one measures from a technique ...

Based on 20 years of observations by NASA’s Hubble Space Telescope, new research sheds light on one of the solar system’s ...

Let’s reimagine the walk of all walks. Not just a neighborhood stroll or a long-distance trek, but a bold journey to the ...

As the Universe expands, this characteristic distance expands as well, allowing us to measure the Hubble constant. In cosmology, just like in any other science, we frequently begin our ...

After leaving Earth, Tianwen-2 will reach Kamo‘oalewa by July 2026. This tiny, elongated asteroid likely spans no more than ...

From it, they calculated the universe’s current expansion rate — known as the Hubble constant, or H 0. They found a value of 76 kilometers per second per megaparsec — but with an uncertainty ...

It's not a solitary endeavor," Freedman said. The concept of the Hubble Constant originated from a Belgian physicist in 1927, and then Edwin Hubble provided the first observational evidence of it.
