Welcome to the grant finale of this mini series and i hope you enjoyed it as much as i did. Probably, if my eyes catch a weird and amazing exoplanet to be found, i will make a post ASAP but for now let's close it with my fifth post and as a theme for the final episode we gonna have planets that changed our way of thinking and gave us hopes as well as motivation.
Basically, i want to finish it with planets that gave a fresh start to scientists!
HD 209458b (Osiris)
Osiris is an extrasolar planet belonging in constellation Pegasus,is 150 light-years away and discovered back in 1999. This planet discovered by the transit method
Transit: the phenomenon in which at least one celestial body moves across the face of another one's and hiding a part of it
and scientists have found both oxygen and carbon in the atmosphere. The name Osiris that it didn't occurred cause of me was given to this planet because the above elements ( oxygen and carbon) are evaporating so quickly that is similar to Osiris story as his brother cut him into pieces.
Is that planet so important?
Damn right it is and i will tell you why right away! First of all as i mentioned above it was the first extrasolar transiting planet ever to be found. Also, Because of the oxygen it was one of the firsts extrasolar planets known to have an atmosphere and an atmosphere with carbon and oxygen. Moreover, a planet that is evaporating so quickly and one of the 2 first planets that observed directly Spectroscopically
Spectroscopy: the study of interaction between matter & electromagnetic radiation. Below is a video that explain its a bit further
In therms of life chances are low as the planet is close to it's sun but worry not as the discovery of Osiris proved to so beneficial for the scientific community as their theories proved right in action, they discover things about our universe they had no idea about their existence and also came a bit closer to understand the universe and our Earth. Finally completing so many achievements by only one planet you can imagine the joy and motivation of those scientists!
KEPLER -22b (Half-life)
Kepler-22b is another extrasolar planet that discovered in December 2011 by the Kepler Telescope, belongs to the constellation of Cygnus and is 600 light-years away from Earth. Kepler-22b is about 2.4 times bigger in diameter than Earth and a star like our sun but a bit smaller and colder with a temperature of 22 Celsius degrees.
So why the big fuss?
As we know the Kepler telescope looks for other planets in the deep space and as an ultimate goal it has to find planets that are habitable and we can go and live to or find aliens. To understand further the progress of Kepler just think that in 2011 they had 54 planets as potentially habitable candidates while by 2017 it had found more than 4000.
Kepler -22b or Half life ( not the game) as i call it is so important as it was the first exoplanet found in the habitable zone of it's star meaning that all the scientists completely loose their minds and were so happy they found something that may contain life and it's similar to our Earth. The similar to our Earth part was the most important cause it gave them motivation to work harder and proved that all their work wasn't for nothing.
In case you haven't read my previous posts and don't get what exactly the habitable zone is let me explain it with simple and plain words. A key difference in the habitable zone with in general the universe is that the water the planets may contain it's not extremely hot or frozen and it's liquid, so when we are talking about liquid water in form of seas and oceans there are higher chances of life to be existed.
Now let's get back to our Half life and understand the reason i gave such a wonderful name. The main reason is that nobody knows exactly if that planet is really habitable and life exists. Surely there are many signs that lead to ''good news'' but some people thing that there is not life there and that Half-Life may be more likely, like Neptune.
I hope you enjoyed this journey as i did too and learn a couple of things about our marvelous universies. I have another series completely different i am gonna lunch next week so don't worry :P. Furthermore, in case you wanna read my oldest parts of the series you can click Here1 Here2 Here3 Here4

Finale!? But there are still so many planets! :( In any case, it's good to bow out while you're at the top. Too often, I see Steemians just milking the rewards pool by stretching their series beyond its limits. Great to know you have a good head on your shoulders. This was such an educational series! Nice work with it :D
thanks a lot! i have some other ideas i wanna try and see how far can go and also i want to be the first one to start with those new series before somebody else think of it too :P
Also about the exoplanets although there so many out there the most unique ones were those that i mentioned so i don't want to bore everyone and myself with the same and same stuff ( for example in a post i had the hottest planet, in between this planet and earth there are 100+ more with more degrees. imagine if i make posts with the same and same attributes abut only the name and Celsius degrees changed :p
Thanks for your support and i hope my other educational series to be as good and even more than this!
The whole series was fascinating.Really nice work there
thanks a lot for your nice words
Wow!! Amazing information about solar system and the planets.
This episode is superb..
Thanks for sharing..!!
thanks for reading it!
I love the way you elaborate this to the extent a non-science persob can easily decode what you are passing across.
Science is the answer to most of Solar and science questions .
Thanks for sharing this
Regards @funkylove
thanks a lot, that's my goal as i am not a scientist either so i just wanna make thing easy for everyone to understand like i would have wanted for myself
Now I know those planets exist! Interesting! Good sharing this one.
thanks a lot!
When I was a kid no extrasolar planets were known. Now we have 4000 in the habitable zone! Amazing.
But this only raises further troubling questions. What about the Fermi Paradox? It seems habitable planets are everywhere, which tilts the Drake equation in favor of life... so why no civilizations trying to contact us? Do they destroy themselves just as they reach space? Or never develop? Are we completely alone after all? Or doomed to destroy ourselves?
that's a thing not even scientist can't answer 100% yet :p
my guess is than in milky way we won't find life or life more advanced than us but far far away that we can't go now and discover what lies there( we haven't even discovered out galaxy in full and even our deep oceans :p ) there might be lives more advanced than us who may consider us as to low technologically and stupid, but whatever i am saying too only time will tell :P
wow I had never heard of either of these planets - and what a fascinating series!! I'll have to go back and read the rest.
So exciting to read about new potentially habitable planets out there. I can't wait to see where astronomy takes the human race next.
yes the possibilities are infinitive! i checked quickly your profile and your post seem really interesting, i will check them in depth later!
Great ending with a teaser for the new yeah we gonna hear soon as we are finding exo planets everywhere as our understanding of looking for them advances with technology like the James Webb telescope, as the James Webb launches we gonna have hoards of them coming one after one.
Really exciting to find what's there for us to look at, the alien planets are sure waiting to be picked up by us maybe we are significantly intelligent in some thousand light years neighborhood. 😁
yes it's really fascinating and bring us steps together to a better future ( i wanna hope at least) and a better understanding of our universe and ourselves
With so many exo planets being discovered so often, atleast finding the exact causes about how our universe was created would be a great achievement :)
Great work,great post.
thanks a lot!
Those are some super cool pictures. I think space is such a fascinating aspect to life.
thanks a lot! it's really fascinating and we can learn a lot about our origin
Very good job, mate. I will go check the rest 4. Of course, you could be kind enough (σαν μικρότερος) and provide the links in a response here :P
ta exo kato kato ola mazi sto telos tou post :p auta p einai mple kai leei here1 here2 ktl ktl :P
Your post was very iinteresting and easy to read and digest. Looking forward to more !
thanks a lot!
