A new story of star formation unfolds Once upon a space-time, a cosmic creation story unfolded: Thousands of never-before-seen young stars spotted in a stellar nursery called 30 Doradus, captured by NASA’s James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favorite for astronomers studying star formation. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust. A side-by-side display of the same region of the Tarantula Nebula brings out the distinctions between Webb’s near-infrared (closer to visible red, left) and mid-infrared (further from visible red, right) images. Each portion of t...

Astronomers have spotted in a galaxy adjacent to our Milky Way what they are calling a cosmic "needle in a haystack" - a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star. Researchers said on Monday this one differs from all other known black holes in that it is "X-ray quiet" - not emitting powerful X-ray radiation indicative of gobbling up nearby material with its strong gravitational pull - and that it was not born in a stellar blast called a supernova. This artist’s impression shows what the binary system VFTS 243 might look like if we were observing it up close. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud, is composed of a hot, blue star with 25 times the Sun’s mass and a b...

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). In a high-resolution image released by the European Southern Observatory (ESO) and including ALMA data, we see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region. Astronomers have peered into a teeming stellar nursery in the Tarantula Nebula - a colossal cloud of gas and dust next door to our galaxy - gaining new understanding of the dynamics of star formation while obtaining a dazzling image of the cosmos. Researchers on Wednesday said their observations offered insight into the interplay between the irresistible force of ...
