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.

A rapidly growing black hole

This Arp 299 system consists of a pair of galaxies, IC 694 and NGC 3690, which underwent a close encounter about 700 million years ago. As a result of this interaction, the system underwent a fierce burst of star formation. In the past fifteen years or so, six supernovae have exploded in the outermost regions of the galaxy, making this system a prominent supernova factory. Credit: NASA

Astronomers have discovered a rapidly growing black hole in one of the most well-known galaxies in the primordial universe

Water on Earth is older than Sun

A study published in Science reveals that the water on Earth is older than the Sun and therefore comes from interstellar space.

Ryugu asteroid is rich in organic molecules

Sample collected from the Ryugu asteroid by the Jap probe Hayabusa2 shows that it is rich in organic molecules essential for life.

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.
