Why is Blue Star hotter than red?
Well, to answer this, a shorter wavelength means greater energy.
This is important because if you look at the spectrum, blue photons have more eery than red photons so the blue star generates more energy and more heat than the red.
To answer simply, the red stars are lower in temperature than the blue stars..
Are red or blue stars brighter?
Blue stars tend to be the brightest, and red stars the dimmest. But more experienced observers will encounter red stars at night that are brighter than white or blue ones.
What color is the hottest star?
Blue starsWhite stars are hotter than red and yellow. Blue stars are the hottest stars of all.
Do hotter stars appear red?
The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red. A color index of a star is the difference in the magnitudes measured at any two wavelengths and is one way that astronomers measure and express the temperature of stars.
What is hottest thing in the universe?
A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That’s more than 366,000 times hotter than the center of the Sun.
What is the color of a dying star?
These stars are in their mid life and are normal average stars. Orange or Red stars have used up most of their Hydrogen fuel and are approaching the end of their lives.
