“You take the light from a star, planet or galaxy and pass it through a spectroscope, which is a bit like a prism letting you split the light into its component colours. “It lets you see the chemicals being absorbed or emitted by the light source. From this you can work out all sorts of things,” says Watson.
What tools are used to study stars?
Astronomical instruments include:
- Alidade.
- Armillary sphere.
- Astrarium.
- Astrolabe.
- Astronomical clock.
- the Antikythera mechanism, an astronomical clock.
- Blink comparator.
- Bolometer.
Can a star turn into a planet?
Yes, it is possible for stars to turn into planets. But this happens for only a specific category of stars- called as brown dwarfs. Brown dwarfs are often called failed stars. They are objects that are too compact in size to be stars, but too huge to be planets.
Is a star a sun or planet?
Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. The planets are much closer, inside our solar system.
What is the coolest main sequence star?
Red dwarfs
