How is a star born?
Stars form from an accumulation of gas and dust , which collapses due to gravity and starts to form stars. ... Stars are born and die over millions or even billions of years. Stars form when regions of dust and gas in the galaxy collapse due to gravity. Without this dust and gas, stars would not form.
How old is the universe?
The universe is (nearly) 14 billion years old , astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
What exactly is black hole?
Black holes are points in space that are so dense they create deep gravity sinks . Beyond a certain region, not even light can escape the powerful tug of a black hole’s gravity. ... Such a burst flings star matter out into space but leaves behind the stellar core.
Is astronomy a good career?
