Nebula



What is Nebula ?

A nebula is a cloud of dust, hydrogen, helium and elements like iron, copper and their ionized vapors present in interstellar space.

How a Nebula is formed ?

In easy words nebula is remnant of  stars after super nova and hyper nova explosions. It mainly comprises of ionized gases.

Why Nebula looks colorful ?

In most of the cases nebulae consists of 70-95 % ionized gases. And because of  presence of ionized gases they seems to be colorful (transition of electrons takes place), for example due to presence of oxygen gas it look green.

How big is a Nebula ?

It sizes from 1AU to 10AU. Just one portion size of earth would weight only few kilograms. 

Does Nebulae has any temperature ?

The temperature of  nebula vary from 10000 degrees Celsius to 200000 degrees Celsius.



 How many kinds of nebula are there ?

There are five types - planetary nebulae , emission nebulae , reflection nebulae , dark nebulae and supernova remnants.

 Diffuse Nebula - Most of the nebula are diffuse nebula with no well defined boundaries. It is divided into three subcategories:-

 Emission Nebula:- Nebula which emits radiation due transition of electrons in presence of ionized gases and cosmic radiations.

Reflection Nebula:- They are visible due to light they reflect. They reflect light coming from nearby and host star.

Dark Nebula:- They acts like barrier to light coming from any star. It either reflects it or absorb. So , they seems to be black. Its presence is detected by infrared and radio telescopes.

Planetary Nebula:- It is formed by small stellar stars in which outer shell of star is expelled out due to strong solar winds and core remains as dwarf star. Dwarf star heats up the near by gases to ionized one. It is also known as Emission Nebula.

Repeated fast radio bursts from space make 'Alien Life' theories alive

Astronomers, including some of Indian origin, have detected repeating energy bursts from a single source from deep space for the second time in history -- giving impetus to theories that there could be evidence of advanced alien life.  A Canadian - led team of scientists found the second repeating fast radio burst from the Canadian hydrogen Intensity mapping experiment telescope located in the mountains of British Columbia's Okanagan Valley. Of the more than 60 fast radio bursts observed to date, repeating bursts from a single source had been found only once before --a discovery made by the Arecibo radio telescope in Puerto Rico in 2015 , the team said in a paper published in the Journal nature and presented at the American Astronomical Society meeting in Seattle on Wednesday. Fast radio bursts are short bursts of radio waves coming from far outside of our Milky Way galaxy and scientist believe fast radio bursts emanate from powerful astrophysical phenomenon billions o...

8 Unbelievable Pictures of Outer Space

Sure, you’re trapped in your house, but there’s an entire galaxy of cool stuff right over your head in the night sky. Space is infinitely expanding (and contracting, but we’ll focus on the expanding), which might relieve the claustrophobia and boredom that come along with quarantine.  Here are eight pictures showing the mystery and wonder of the universe.  STAR CLUSTER Just how it sounds, a star cluster is a bound group of stars. Young clusters contain fewer stars with more distance between them. As a cluster gets older, the stars move closer together, united by gravity. You can see some star clusters in the night sky with the naked eye. One is the constellation Seven Sisters, another’s inside the constellation Cancer. The closest star cluster, Hyades, is just 153 light-years from earth and you can see it inside the constellation Taurus.  NEBULA  The word nebula is Latin for cloud, which is also a perfect description. Images of nebulae from space are be...
