The rare sight of a Wolf-Rayet star - among the most luminous, most massive, and most briefly detectable stars known - was one of the first observations made by the James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments.

New observations have revealed a spiral pattern in a disk of material around a still forming, but already high-mass, baby star. This indicates that there is gravitational instability in the disk, which has important implications for how high-mass stars form.

While analyzing data from the first images of a well-known early galaxy taken by the James Webb Space Telescope, astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy - one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.

Using the powerful James Webb Space Telescope, astronomers have observed massive candidate galaxies at the beginning of time, up to 100 billion times the mass of the Sun which, if confirmed, would contain more mass than was thought to exist in the whole Universe at that time.

New astronomical measurements in the infrared range have led to the identification of a heretofore unknown class of asteroids. They are located in the asteroid belt between Mars and Jupiter and are - similar to the dwarf planet Ceres - rich in water.

When neutron stars collide, they produce an explosion that, contrary to what was believed until recently, is shaped almost like a perfect sphere. Although how this is possible is still a mystery, the discovery may provide a new key to measuring the age of the Universe.

If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon , hydrogen, oxygen, nitrogen and sulphur.
