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.

M31 shows clear signs of galactic migration

An international research team has discovered clear signs of galactic migration in our neighbor, the Andromeda galaxy M31.

Mapped the Local Bubble of the Solar System

Astronomers have traced the magnetic field of the local bubble using data obtained from Planck and Gaia. In the image, the pink and purple vector lines on the surface of the bubble represent the orientation of the discovered magnetic field. Credit: Theo O'Neill / World Wide Telescope

Scientists have discovered and mapped the local bubble surrounding our Solar System, influenced by a strong magnetic field

The Earth hit by an energy explosion

Illustration of a neutron star.

The Earth being hit by an explosion of energy released by the fusion of neutron stars allows researchers to study these phenomena.

James Webb observes an intergalactic shock wave
