Astronomers describe the star birth web of the cosmic Tarantula Nebula

This composite image of the star-forming region of Doradus 30 — also known as the Tarantula Nebula — reveals areas of cold gas that could collapse to form stars. (Image credit: ESO, ALMA (ESO/NAOJ/NRAO)/Wong et al., ESO/M.-R. Cioni/VISTA Magellanic Cloud survey.) The newly released image of 30 Doradus, also known as the Tarantula Nebula, reveals thin, spiderweb-like strands of gas that reveal a dramatic battle between gravity and stellar energy that could give astronomers an idea of ​​how massive stars have shaped this star formation. regions and why they continue to be born in these molecular clouds. This high-resolution image of the Tarantula Nebula, located 170,000 light-years from Earth, consists of data collected by the Atacama Large Millimeter/submillimeter Array (ALMA). Located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, the Tarantula Nebula is one of the brightest star-forming regions in our galaxy’s backyard. It’s also one of the most active in term

Images of the Carina Nebula from the Webb and Hubble telescopes paint a stunning view of the universe

A stellar nursery discovered more than 250 years ago will teach astronomers new things about how stars come to life with the help of sharp vision from the James Webb Space Telescope. The powerful new $10 billion observatory, located in space about 1 million miles from Earth, takes new images of the star-forming region within the Carina Nebula. The image captures incredible detail previously unseen by the Hubble Space Telescope. The Carina Nebula has been a popular target for study for many years because it exhibits cosmic events lasting for a very short time – only about 50,000 to 100,000 years. The nebula lies in the Milky Way about 7,600 light-years away and is home to other well-known cosmic objects, such as the Keyhole Nebula and the unstable supergiant star, Eta Carinae. Astronomers have given its features several pet names as well, such as Mystic Mountain and Cosmic Cliffs.

When does the sun blow away the solar nebula?

The story of the origin of our solar system is quite well known. It reads like this: The sun began as a protostar in the “solar nebula” more than 4.5 billion years ago. Over the course of several million years, the planets emerged from this nebula and disappeared. Of course, the devil is in the details. For example, how long exactly did the protoplanetary disk that gave birth to the planet last? A paper was recently submitted to Geophysical Research Journal take a closer look at the planet-born crèche. In particular, it shows how the magnetism of the meteorite helps tell the story. About That Solar Nebula About 5 billion years ago, the environment of our galaxy was a nebula made of hydrogen gas and some dust. It provided the seeds of what became our solar system. Somehow, this part of the molecular cloud started to clump together on its own. Perhaps a passing star sent shockwaves and ripples through the dust and caused it to compress. Or, maybe a nearby supernova did. What
