November 19th lunar eclipse

19/11/2021

RAMESH S KRISHNA

Introduction:
A lunar eclipse will happen when moon enters earth's shadow. It would happen when we have a full moon . This is more like a transit method which helps us to find a exoplanet.  I'll tell you in detail about solar eclipse when it happens! So, stay tuned with by blog page! While a full moon is raising, it would be red.

How does a lunar eclipse happen?:


I've mentioned only for a lunar eclipse. Do not confuse with a solar eclipse. A lunar eclipse happen when moon enter's earth's shadow. There are 2 shadows of earth. 

Penumbra:  Its the lighter & 1st part of the shadow. It generally happens in the edges of earth[while its evening in the point]. Light entering earth's atmosphere would scatter & go to deep space. The light which goes is blue in color.
Umbra: It is the darkest part of shadow. Its the place where moon turns red. It will be late in the night at the location of Umbra.

Types of lunar eclipse:

Total: It happens when Moon, Earth & the Sun are perfectly aligned. It will happen when moon is in the umbral shadow. Moon will turn sunset red color. The longer wave-length, colors like red will be bent & sent to moon. 


Partial:  Earth, Moon & The sun wouldn't perfectly align . The part of a moon will turn very dark. From a full moon to waning/waxing gibbous.

Penumbral: It will happen when moon passes through penumbral shadow. It is very subtle that many wouldn't notice at all.


Where is this eclipse visible[NOV 19th]?

Since, I live in Chennai, India, its not visible. If I was 1000+km to the north, the eclipse would be visible a bit :(

The problem IN ISS

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...
