Hi,
why space news again? Well new planet has been found, if you know something about astronomy this would not really excite you since new planets are found “all the time”. Well what if I say to you that Solar System has new planet? The planet Nine?
Also on ISS first flower was able to bloom!
When I saw the message about planet Nine I was very excited, but most media made again a mistake to say that it was found, that is not right it was not found yet. There is a strong evidence that such a planet could exist in our Solar System (if this planet is really approved to have been found, I promise to make another post about for “Planets of our Solar System”).
This planet would have mass to about 10 times the mass of Earth making it about the same size as Uran and Neptune, which means that it would be ice giant.
Above you can see the artist’s impression of such a planet. The evidence for it is in the movemenent of TNOs (trans neptunian objects). Those are things like Sedna which you can see below.
Those objects as well as planet Nine have highly excentic orbit. It is clear that we can detect them only when they are close to Sun which means that there are surely more of them. The problem is with their orbit lined up in plane which is very improbably without planet Nine. It’s magnitude is very low, to about +20 or so making it really hard to see even if we were able to find it’s exact spot on the sky. It could orbit in distance ranging from 200 AU in afelion and 1000 AU in perihelion. Caltech is the institution that published about it 20.1.2016.
This week also for the first time flower called zinnia (it is on the picture) finally bloomed. Why this plant? Because it has longer growth of about 60 to 80 days which is more then plants which were planted before.
This flower is a big step forward to grow tomatoes.. tomatoes for food!
That is why it is so important, we need to be able to make a food in microgravity to sustain when traveling through deep space.
