The Hubble Space Telescope is working with the Atacama Large Millimetre/submillimetre Array radio observatory to survey nearby galactic environments to learn more about how they influence the formation of stars and star clusters. One of the galaxies imaged by Hubble for the PHANGS-ALMA survey, the Great Barred Spiral in the constellation Fornax is a prime example, showing off hundreds of infant stars and enormous regions ablaze in blue and orange swirls of gas and dust that will provide the raw material for future generations. Known as NGC 1365, the galaxy is located some 60 million light years from Earth.
The most luminous galaxy known in the universe — the quasar W2246-0526, seen when the universe was less than 10 percent of its current age — is so turbulent that it is in the process of ejecting its entire supply of star-forming gas, according to new observations with the Atacama Large Millimetre/submillimetre Array (ALMA).
The bipolar star-forming region Sharpless 2-106 some 2,000 light-years away in the constellation Cygnus looks like a soaring, celestial snow angel in this image from the NASA/ESA Hubble Space Telescope. Twin lobes of super-hot gas, glowing blue in this image, stretch outward from the central young and massive star. This hot gas creates the “wings” of our angel.
ESA’s Planck satellite has revealed that the first stars in the universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed to account for reionising atoms in the cosmos, having completed half of this process when the universe had reached an age of 700 million years.
