The missing matter of galaxies

La galassia a spirale M99, ripresa dal telescopio spaziale Hubble

An Italian research team has discovered the amount of missing baryonic matter in galaxies that we had not been able to detect so far.

Shockwaves shake the cosmic web

Astronomers have detected huge shockwaves shaking the cosmic web that connects all the galaxies in the universe.

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

James Webb and the impossible galaxies

An international team discovered with James Webb’s CEERS images impossible galaxies that shouldn’t have formed.

James Webb Captures Star Formation

The James Webb Space Telescope captured this image of a galaxy cluster (SMACS0723). The five magnified galaxies are so distant that we observe them as they were when the universe was between one and five billion years old. Credit: NASA

From the image posted by James Webb on July 31, researchers have studied the formation of stars in the early moments of the Cosmos.

A research team has discovered a rocky planet Wolf 1069b just 31 light-years away from Earth, very similar to our planet.

A new map of the Universe highlights an incomprehensible discrepancy between the accepted cosmological model and the results obtained.

James Webb Captures Galaxies Formation

A group of small galaxies, seen almost 13 billion years ago, likely in the process of forming a massive galaxy. The colors are composed of three different infrared colors. The white horizontal bar shows a scale of about 20,000 light-years. Credit: Shuowen Jin et al. (2023)

James Webb Telescope has captured the formation of galaxies, expanding our knowledge on the birth of these cosmic objects.
