All stars spend the majority of their lives as so-called main-sequence stars. Consequently the vast majority of stars—90% or so—are undergoing hydrogen-helium fusion at any given time.
Deciphering how stars form within turbulent, dense clouds of molecular gas has been a challenge. An innovative technique that uses a tree diagram provides insight into the process. Stars and ...
“This allows us to use the colour-magnitude diagram as a clock,” he adds. ... And later, at the epoch 4.5 billion years ago, another generation of stars formed from that element-rich gas.
Blue supergiants may be formed by two stars in a binary system merging. Casey Reed, NASA. Blue supergiants are huge, luminous stars that are some of the most ...
Ever peer up at the sky at night and wonder where all those stars came ... “We’ve calculated that about 15 supernovae have gone off over millions of years to form the Local Bubble that we see ...
Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...
One of these stars immediately jumped out as an oddity. It had much, much less of the heavier elements in it than any other star yet seen in the Large Magellanic Cloud. This means it was probably ...
Sometime between the Cosmic Microwave Background, at 380,000 years, and that first galaxy, the first stars must have formed. Schematic diagram of the Universe's history, highlighting reionization ...
Lynds bright nebula 483, seen in infrared light by the JWST. (Image credit: NASA/ESA/CSA/STScI) The jets are formed by material with a rich abundance of varied molecules falling onto young protostars.
A cluster of stars known as NGC 346, which is more than 200,000 light-years away from Earth, has become of interest to astronomers because it resembles the conditions of the early universe.
