  • USA's president, Joe biden revealed the 1st coloured photo from JWST, Today
  • This photo covers less than a  grain in the Universe
  • On 12th July, NASA will release the other images like this
  • This is just 12 1/2 hours of exposure time whereas an image like this took 11 days for Hubble
  • You can see the curve in this image, it is because of the light passing through objects & getting curved
In images like this, if more galaxies come into the image, it will add even  more galaxies. Let me explain.

According to the European astronomers Albert Einstein, GRAVITY CURVES LIGHT.
Just like that, it happens here too! When a galaxy appears, it also curves & passes the object behind it!

Also, all the images are not in real-time. Yes.

The speed of light is about 300000 KMPH. So, it does take time to reach us. This same thing happens here too! The light from the galaxies started their journeys a long time back, but since the universe is expanding & also the light takes time, it just reached us. This means, if you were on a planet about 77-Million light-years away, you could see Dinosaurs roaming this Planet. 

                                 COMET K2



This is a comet much like others, having a hyperbolic orbit that orbits the sun. This comet makes a close approach to Earth this July. The luminosity peaks on July 14th. This comet is really large about twice the size of Mt. Everest. K2 reaches its perigee on Dec 19. It is most likely not visible to naked eye in urban skies & having a slim chance to spot it in rural skies{Magnitude +7}. This magnitude is much like Uranus's. While being in perigee, it is 2.5 AUs away from Earth. So, don't miss this opportunity.
You can see it in the evenings once the Sun sets.


Bye for now!!
See you guys soon in my 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

Image
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...
