Our Sun is medium-sized, average temperature, and middle aged. Very hot stars are what color? In the vastness of space. None of these are correct. We are made of star stuff. In main sequence stars, what happens during nuclear fusion? Large amounts of energy are depleted. Find it out with this astonishing big brain quiz!

It is a bit bulged at the centre due to its rapid rotation. Unfortunately, this star is invisible to most of the northern hemishpere along with other luminaries like Canopus, Alpha Centauri and stars of the southern cross. I am really lucky because from our place i. Summer Triangle is a beautiful triangle shaped asterism formed by Vega, Altair and Deneb.
It is visible during summer in the northern hemisphere and during winter in the southern hemisphere. Vega and Altair are main sequence stars located within 30 light years whereas Deneb is a white supergiant located at a distance of more than light years! Though there are many stars which are so distant and still visible to the naked eye, Deneb is among the brightest stars in the night sky, which places it above all other stars which are equally distant.
The Winter Triangle is the counterpart of the famous Summer Triangle. The Winter Triangle is visible during winter in the northern hemisphere and during autumn in the southern hemisphere. This winter asterism is formed by Sirius, Procyon and Betelgeuse. This triangle has brighter component stars and is somewhat smaller than the Summer Triangle.
The Pistol star is a 'hypergiant' a term used for stars which are more luminous than supergiants. It is more massive than Eta Carinae! Being one of the most luminous and massive stars in our galaxy, it is located near the galactic centre in the constellation of Sagittarius.
It is said to have created a nebula around it by the rapid ejection of its mass. This nebula is called the Pistol Nebula because of its pistol shape. This name, followed with some numbers, is given to some ultra massive, highly luminous hypergiants which are usually present in dense star forming regions like the Eta Carinae nebula or associations of stars like the OB association in Cassiopeia.
Aludhra is an ultra luminous blue-white supergiant in the constellation of Canis Major. Saiph is also a supergiant, but much smaller. Nebula collapsing under itself. Supernova of old star. Planets collapsing. Fusion of atoms. Stars And Galaxies II. This quiz evaluates each student's level of comprehension following a lesson on stars and galaxies.
