This is a recently released Hubble's image of the COSMOS field - part of the sky used by astronomers to study the distant universe. It contains pictures of many galaxies, some of them with redshift over 2. That means their light has been stretched by the expansion of the universe into the infrared part of the electromagnetic spectrum.

The COSMOS (Cosmological Evolution Survey) is a part of the sky several times bigger than the disc of the full moon. Hubble’s view is much narrower though, so astronomers have to put together hundreds of images to see the whole picture.

The European Space Agency released new data from its Gaia astrometric mission. The new data release (DR3) from the Gaia telescope will change once again our view of our own galaxy. Just like the previous releases, which revealed the history of galactic mergers, stellar positions and movements and so much more.
European space observatory Gaia measures precise positions of stars in our galaxy, however it can also look for exoplanets. Scientists now report confirmation of two exoplanets discovered by the spacecraft.
