A group of researchers has identified and three-dimensionally mapped a bubble of galaxies, Ho’oleilana, a relic of the Big Bang

Missing information of black holes

Research based on a different approach to general relativity could yield new information about black holes

The entire universe is destined to evaporate

A new theory claims that the entire universe is destined to slowly evaporate, emitting energy in the form of Hawking radiation

Astronomers around the world are witnessing in real time the death of a star named BELLS1 in the Triangulum galaxy

The detailed map of dark matter

Il Big Bang (a sinistra), le linee ondulate illustrano la distorsione generata dalla materia oscura. La luce deformata ricevuta dall'ACT (a destra)è stata usata per generare una nuova mappa della materia oscura.

Through the study of the cosmic microwave background radiation, ATC researchers have created a new detailed map of dark matter

Tycho supernova is a particle accelerator

A research team has discovered that the Tycho supernova is a cosmic particle accelerator that produces cosmic rays that reach us

James Webb and the reionization of the Universe

An artist's representation of what the first stars that illuminated the cosmic dawn would have looked like.

A new research based on images from the James Webb Space Telescope aims to understand how the reionization of the universe occurred.

Dark energy could create other Big Bang

A new research suggests that the dark energy may be responsible for multiple Big Bang that will occur in the future of the universe.

Black holes are the source of dark energy

An international team has discovered the first evidence that black holes are the primary source of the dark energy of the Universe.
