" The birth of a star is a captivating balance of gas, dust and energy. The transition from quiet cosmic particles to radiant celestial bodies is a process as intricate as it is magnificent. Read on to explore the steps and stages of star formation, illuminating the evolution that lights up...
The birth of a star beginswhen massive clouds of dust and gas start to collapse and break down. How does thishappen? It happens through the force of gravity.Gravity bounds the elements together to create a protostar. The protostar isbasically a baby star, and grows into a star through its...
What is meant by the term ion? Explain how a star is formed. How do molecules attract one another? Explain using two water molecules as an example. Why are some complexes of d-block ions colored? Explain why the copper element has two ion charges. ...
Special emphasis is given to the formation of massive stars, which requires that several physical processes operate, as distinct from low-mass stars which are more easily formed. The picture of star formation is compared in some detail with many new and old observational aspects of the subject,...
Hubble's Law is a major piece of evidence that the universe is expanding — his work formed the basis of the big bang theory of the origin of the universe. The Doppler Effect Much like the high-pitched sound from a fire-truck siren gets lower as the truck moves away, the movement of...

elevator door gate. So we go up to the top and just sort of walk along the roof. And as I’m looking out over the rooftop I see this really white guy just laying out in the sun. It was a burning hot day and I just remember he was very white. And Izzy is like, “This is ...

years across but is a particularly busy stellar nursery. This region is full of young stars, and these stars seem to be forming in a flowing spiral structure of gas and stars which the researchers compare to a river. This could help explain why the rate of star formation here is so high...
Detailed observations of molecular gas in a tidal dwarf galaxy have important implications for our understanding of how stars are formed. A lot is known about galaxies. We know, for instance, that the stars within them are shaped from a blend of old star dust and molecules suspended i...
