 Hello all! Nice meeting you back again! As always, please read till the end. If you haven't read the last two parts of this series, here is the link: Part 1, Part 2.

 Now let us continue from the letter "N".

N=

Nadir=Opposite of the zenith, from the position of Astronomer
NASA= US's government's space organization, National Aeronautics & Space Administration
Nebula= A gas cloud where stars form
Neutron star= If a star that went supernova was lighter, it will become a neutron star
New moon= The phase of the moon when it is fully black[no light reflecting]
North star= Polaris, it indicates 0 degrees of north
Nova= Explosions of stars
Nuclear fission= Heavier nucleus turns into a lighter one
Nuclear fusion=A combustion of Hydrogen atoms to form heat & light

O=

Observatory= Places where we observe the sky
Occultation= When a body is being hidden by another
Oort cloud= A large group of chunks that orbit the sun
Opposition= When two bodies are exactly in the opposite sides of the sky
Orbit= A path in which an object circles a larger body
Orbital eccentricity= Measurements of the orbit with the shape of the circle
Orbital inclination=Angle of a body in which they orbit
Outer planets= Planets that are after the asteroid belt

P=

Parallax= The change of two object view in different places
Parsec= 3.26 LY is a parsec
Partial eclipse= An eclipse that doesn't cover fully
Penumbra= Lighter shadow of an eclipse
Perigee= Lowest distance in an orbit of a manmade object
Perihelion= Lowest distance in an orbit of a natural body
Phase= Illuminations of light from an object
Photon= The particle that makes light
Photosphere=Layer in star after the surface that sends heat & light into space
Planet= A body that is spherical & orbits with its own gravity
Planetary nebula= When smaller stars run out of gas, they envelope
Plasma= A state of material
Pluto= A dwarf planet
Pole star= Another name of north star
Probe= A manmade object that travels through space to get more data
Proto-planet=Young planet
Proto-planetary disk= Once, a star forms, a large amount of gas will be orbiting to get inside the star
Proto-star= Young star
Pulsar= A neutron star that rotates super fast & emits a lot of radiation

Q=

Quarter Moon= 1/2 phase of the moon & occurs after 6-8 days after new moon
Quasar=Extremely luminous star
Quasi star= A star that has a black hole inside it & the radiation from the black hole provides energy
Quasi=Radiation source

R=

Radiation= Giving energy in the form of the electromagnetic wavelength
Radio= Transformation of energy in waves
Red giant= 1. A large star that is red due to temperature, 2. A small star becomes big when gas runs out
Redshift=Light from the object moves toward the red spectrum due to objects in its way or Distance
Reflector telescope=Once the light enters the telescope, it is reflected to reach the eyepiece
Refractor telescope=Uses lens to create images
Retrograde motion=Reverse moment of an object in the sky
Revolve=Move on an axis & orbit something
Ring galaxy= The galaxy that has ring shape
Rings= Object that has a shape like a ring & surrounds a planet
Roche limit= An invisible ring that rips apart an object when it comes to close
Rotation= Causes day & night process.


Hope you liked it.

Meet you all in the next blog!!

The problem IN ISS

Image
I'm a ten-year-old passionate space enthusiast who has just started to blog. In this blog and my following blogs, we will be going through the interesting happenings in the world of Astronomy and rocketry. Please keep supporting me. Thanks Trouble in ISS Nauka’s docking problem   By Ramesh S Krishna Nauka is a Module launched by Russia in a proton rocket on the 21st of July 2021. It’s an MLM  [Multipurpose Laboratory module]. It will dock at the docking port of the Zvezda module , where previously the PIRS module was docked. The PIRS was undocked and re-entered the atmosphere of earth on July 26th, 2021 and after spending 7252 days docked to the station. After the undocking of PIRS and before Nauka’s docking , the robotic arm went and connected with the arm of the Zarya module and checked the port on which PIRS was docked. There were concerns that the astronauts should go for an EVA and check the docking port but the port looked perfect so they didn’t go for an EVA.  Wh...

Snow moon

Snow Moon February's full moon is also known as the Snow Moon. Every full moon has its special name. February's one is the snow moon. Why snow moon? Simple! Since winter is going on and it is snowing in most parts of the earth.  More on this: Sunday, 13th of Feb/2022.  I came to my grandparent's place, my friend Nishanth had also come there. I was pleasantly surprised when I came to know that he was also an astronomy buff! I went down to bring my Astromaster 70AZ. Meanwhile, he too joined me.  So, we started to stargaze. First, we had a gorgeous view of the moon. We spent about a quarter of an hour looking at its beauty! Then, I gave him an idea to look at the winter constellations, like Orion, Taurus. But, they were about to reach the zenith. It is tough to navigate. Then, We had an idea to look at Sirius, the dog star. Since this is February, it is also a good time to look at these stars. We spotted Sirius. Just near to it, there was Sirius B. The dense object, White dw...
