A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This ...

One such problem, known as the Hubble tension, is a difference in measuring the present ... Now, adding a twist to that theory, a research team has explored the possibility that the phase change is ...

Hubble’s original estimate was 500 km/s/Mpc ... Yet another mysterious character that could account for the discrepancy is “dark radiation.” This theory proposes the existence of a new class of ...

Hubble had already used this knowledge in his ... His results showing that the universe was expanding supported a theory that had been proposed by Georges LeMaitre in 1927. A universe expanding ...

This "other theory of gravity" uses a different recipe ... promise that it could solve the cosmological issue related to the Hubble tension and could explain the nature of the late-time cosmic ...

Even Einstein was reluctant to endorse this extension of his theory of general relativity. In 1929 at the Mt. Wilson Observatory in California, Edwin Hubble discovered that galaxies were moving ...

The Hubble Space Telescope captured an image of a star and a spiral galaxy, both in the constellation Virgo. But the photo is an optical illusion. This Hubble Space Telescope image shows a spiral ...

A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf ...
