10 hypothetical stars you don't know about

Blue Dwarf :- It is theorized to be developed from a red dwarf when it looses most of it's hydrogen supply.We haven't found any blue dwarf because red dwarf fuses their hydrogen slowly and currently the universe might not old enough to produce any blue dwarf.

Black Dwarf :- It is thought to be the come from a white dwarf which has exhausted all it's fuel and heat energy which now no further emits radiation and are very hard to detect, fortunately, it do retain it's mass allowing scientists to study it's the gravitational field.

It is concluded that the time required for a black dwarf to be formed is longer than the age of the universe thus we haven't found it yet.

Frozen star:-There is a probability that this star will form in the distant future when the abundance of heavier metals will be more than it is today which is known as the metallicity of the interstellar medium.

It is calculated the temperature of this star will be 273 K or 0-degree celsius. These stars will belong to the spectral class of 'H'.

Planck star:- It is a  hypothetical star that has density equals to the Planck density 9.9 x10^-27 kg per meter cube.

Preon star :- A hypothetical star which is considered to have the core of preons(point particles)

Quasi star :- It is a hypothetical star that might existed at the early stage of the universe that was powered by the black hole at it's center unlike conventional stars that nuclear fusion energy.

Thorne–Żytkow object :- It is predicted that when a red giant or super red giant has a neutron star at it's a star it is theorized as Thorne–Żytkow object. Apparently, HV 2112 is the most probable of this star class type.

Boson star :- A hypothetical star that thought to be made up of bosons like gluons, photons, Z boson etc.

Iron star :- The theory states that fusion occurring in stars will eventually convert light particles into heavy particles and then decay into iron converting all the mass of the star into cold iron balls.

Population III star :-  These are the hypothetical stars that existed at the very early stage of the universe after the big bang.

These are the stars that started producing heavier elements at their core and helped made life possible as we know it today

Understand the Background of Aurora Borealis

What is an aurora? Aurora Borealis or northern lights is one of the most beautiful phenomena that nature has given us. It is a natural light display in the night sky. It is mainly observed in the high latitude areas.  It is an impressive and fascinating demonstration of how the very fast-moving charged particles interact with the atmosphere of the earth due to the magnetic field of the earth. It worth bearing the cold outside to experience this unforgettable and soothing scene. It makes you feel connected to nature and the divine. People have often confusion between aurora borealis and aurora australis but there is no difference between except for their location when the lights are observed in north pole then it is called as aurora borealis( or northern lights) and when seen at the south pole it is called as aurora borealis(or southern lights). Illustration of aurora formation What causes this amazing and magical phenom enon?   Our sun is a giant ball of g...

Here is the list of five habitable planets we have found so far :-

1.)   Gliese 667Cc  Gliese 667Cc is an exoplanet found on 21 November 2011. It is the member of a triple star system Gliese 667. It is situated in Scorpius constellation approximately 23.61 light-years away from the planet earth.  It has an orbital period of  28 earth days. It is also known as  HD 156384Cc. The exoplanet was found using the radial velocity method.  It is approx 3.7 times heavier than the the earth.  2.)   Kepler-186f It was found on 17 April 2014 by Elisa Quintana. Kepler-186f is an exoplanet orbiting a red dwarf 582 light-years away from the earth. It has a radius of 7,454.1 km with an orbital period of 130 days. It is the first planet with discovered in habitable zone which has a roughly equal radius with that of our earth. The discovery of Kepler - 186f confirms that the habitable planets like our earth exists somewhere in the universe.  Kepler-186f is situated in the constellation of Cygn...
