A star, like our sun, burns hydrogen into helium. It later burns even heavier elements, and the star’s end comes, expelling its outer layers and has its inner core either contract or collapse down depending on what type of star it is. When stars extinguish, they collapse quickly under their own weight. Some stars that are large enough end their lives by exploding in a ...

Including our own sun, stars are hot balls of glowing plasma held together by their own gravity, which is very intense. Stars are always crushing themselves inward, and the gravitational friction of this causes their interiors to heat up. Though it's a mere 5,800 Kelvin at its surface, a star can be 15 million Kelvin, which is very hot, at its core.
The intense pressure and ...

Nucleosynthesis is the process by which atomic nuclei are created from pre-existing nucleons like protons and neutrons. Some of the major types of nucleosynthesis are, Explosive Nucleosynthesis, Stellar Nucleosynthesis, Big Bang Nucleosynthesis, Black Hole Accretion Disk Nucleosynthesis and Cosmic Ray Spallation. Stellar Nucleosynthesis is the term used to denote the nuclear reactions taking ...

As the name suggests these are two stars orbiting around a common center of mass. Binary star is the most common type of multiple star system. More than four-fifth of the light that we see are part of the multiple star system. One could be brighter than the other or both can have the same brightness. Binary stars provide information about the mass of a star, the size, the temperature and the ...

The Hertzsprung-Russell diagram (H-R Diagram) was developed by Ejnar Hertzsprung and Henry Norris Russell in 1900s to study the stellar evolution. The diagram shows the absolute magnitudes or luminosities versus their stellar classifications or effective temperatures, in other words, it shows the stars brightness against its temperature. This diagram suggested that the stars ...

A star is an object which has a mass which is capable of igniting fusion to crush atoms of hydrogen into helium. These stars are formed when large gas cloud collapse inward. At about 10 million K, the hydrogen nuclei fuses into the helium nuclei to form the star. Stars are classified based on their luminosity, size and lifespan. They are classified into brown dwarfs, red dwarfs, yellow ...

UY Scuti is the largest known star. This star was discovered by German astronomers in 1860. Yet it was in 2012 that the actual size of UY Scuti was documented. It's radius is between 1,054,378,000 and 1,321,450,000 miles in size. It is about 1,700 times larger than the sun and is said to have the largest overall size.
Even through the star is very large, you can not easily ...

Star clusters are groups of stars that have the same origin and are bound together by a gravitational bond for some time. This helps astronomers to study about stellar evolution and ages. There are two types of star clusters, open clusters and globular clusters.
Open clusters have anywhere from a dozen to many hundreds of stars. They consist of the younger stars in the galaxy ...

Neutron stars have a mass which is 1.4 times that of a sun and are city-sized stellar objects. They are commonly formed at the death of another larger sized star. As this explosion occurs, it's core continues to collapse and the gravity tends to tighten it to the extent that the protons and electrons combine to form neutrons hence the name “neutron star”.
The gravity at ...

The answer to this is that, “because it is painful”. If you have talked to any mother who had a natural delivery, they will explain their pain as a 100 times intensified version of their menstrual cramp combined with a feeling of being stabbed, severe pressure and for some intense waves that feel like diarrheal cramps. This pain is caused by contractions of the muscles of the ...
