Astronomers think they may have identified a new class of astronomical object — something that looks like a galaxy in every ...

Across the observable universe, galaxies appear as luminous islands of stars and gas, anchored by invisible frameworks of ...

In a groundbreaking discovery, astronomers using the Hubble Space Telescope have identified a new type of cosmic object, affectionately dubbed "Cloud 9." This intrig ...

Astronomers have identified Cloud 9, a nearby dark matter halo filled with gas but no stars. The discovery supports key predictions about how galaxies form and why some never do.

Recent observations from the James Webb Space Telescope (JWST) are overturning our certainties about the timeline of the Universe. The reionization period, previously thought to have ended around one ...

New analysis of data taken by the European Space Agency’s (ESA) Planck spacecraft of the cosmic microwave background (CMB) has revealed that the “epoch of reionization” occurred much later than ...

Cosmic reionization denotes the transformative epoch when the first luminous sources emerged, ending the cosmic dark ages by ionising the pervasive neutral hydrogen. This period, which encompasses ...

First, there was the Big Bang, and then there was light. Roughly 400,000 years after our universe formed, the hot environment from the Big Bang finally began to cool. Before this moment, the universe ...

New research suggests that reionization alone is not able to stop star formation in dwarf galaxies, as had been expected. A team of astronomers has provided evidence suggesting that reionization alone ...

During the first billion years of the Universe’s history, the gradual cooling from the Big Bang was reversed, and much of the gas was re-heated and ionized. This event, known as reionization, happened ...
