These discoveries join the discoveries of eight other planets previously observed by the Kuro team. In each of the cases, observations from the ground are required that complement the spacecraft data and make it possible to determine with certainty the size and mass of the planets. The team investigating these discoveries also includes Prof. Zvi Maza of Uni' Tel Aviv
Today it was announced that the French CoRoT spacecraft recently discovered seven new planets outside our solar system. Each of the seven new planets passes in front of its sun and creates for us a small black spot on the face of that sun. For over two years, the Coro spacecraft has been measuring with great precision the light intensity of hundreds of thousands of suns, which appear to us as distant stars in the night sky. The spacecraft's international team was able to detect small dips in the light intensity of a small number of suns, dips caused by obscuration by planets each moving around a different sun. The only Israeli on the spacecraft team is Professor Zvi Maza from Tel Aviv University.
These discoveries join the discoveries of eight other planets previously observed by the Kuro team. In each of the cases, observations from the ground are required that complement the spacecraft data and make it possible to determine with certainty the size and mass of the planets. The CoRoT team uses various observatories in the world, including those located in the Canary Islands, Chile and Hawaii, including the Tel Aviv University Observatory in the Negev. Despite the enormous distance to the planets that were discovered, it is possible to estimate from the observations their size and the amount of mass, and from this to get their average densities. In six of the cases published today, the stars discovered are in the mass range of the planets, and in one of the cases the star hiding its sun is a little heavier and is called a brown dwarf by the researchers.
The discovered planets are different in nature from each other. "Each star that is discovered is a piece of information in solving the puzzle of the creation and development of the planets" says Dr. Magali Deleuil from Marseille. "The more planets we find we can expect to better understand the processes involved."
Among the discovered planets is CoRoT-8b - the smallest planet in the group of new planets. It can be assumed that in its structure it is similar to the planets made of ice in our solar system - Uranus and Neptune; CoRoT-10b – a planet with an extremely long orbit. In its orbit, the planet moves closer and further away from its sun, and the amount of light and heat hitting it changes by a factor of ten! And finally, CoRoT-15 - whose mass is sixty times greater than the mass of Jupiter, the largest planet in our solar system. Such objects, the brown dwarfs, are rare and therefore the great importance of the discovery.
"All the new planets," explains Professor Maza, "are new worlds that we had no idea existed before Koro's observations. We are likened to Columbus sailing his ships beyond the horizon to worlds that excite the imagination. However, unlike Columbus, who found lands whose nature and weather were similar to the one he left behind, in our case the planets, their suns and the distances between them are so different, and therefore the surprises that await us through the telescope can exceed any imagination.

Maybe one of these has life?
For a contract in the stars. There is a problem of research progress in objects that do not exist. Please contact Zechariah Sitchin who invented this falsehood and ask him.

my father
something new ? Have you checked these links?

Please direct me to the link so I can check your claim
Hello father
Rumors are circulating this week that the star "Nibiru" or whatever it is called, is there any real basis for the rumors or is it the Mayan fans again?
Thanks
Hello from Mirom Golan
So I understand that you are a constant traveler in the vastness of the cosmos and have already visited many friends from other planets
Are you so sure of your answer? Is there a certain basis for your statements?
11, the answer to your question is yes.
It is absurd to think that we are alone in the universe
So there is more. But is there another place in the cosmos where there is protein or mitochondria?
ok i give up Is there anything in our entire cosmos that resembles the simplest computer program?
This opinion of yours stems from mental anxiety. Man will not discover all the secrets of the universe.
In my humble opinion, if all the secrets of the universe are revealed, man may destroy it, as he does with joy and age, regarding the planet Earth.
Pretty!
If yes, I have been updated - four times as much as DHA and not six times - thanks to Michael for the link
First, the comment regarding the drawing (why there are more than seven planets there) as well as the answer about it are not relevant - the drawing is only an illustration - please note that the seven planets were not discovered around the same sun, so the drawing as it is is probably incorrect.
As for the anonymous question,
It was noted that the smallest star discovered is a star similar to Uranus or Neptune - which means that it is probably a gas giant and not a small star similar to the Earth.
In general, the method used by the Koro team is to discover the planets by the shadow they cast on their sun when they pass between us and it - this shadow is of course not visible (since the sun is a completely point source for us) and is reflected in a slight decrease in intensity that is proportional to the area of the cross section of the planet divided by the cross-sectional area of the star.
The radius of the Earth is about one hundredth of the Sun's radius, so it will result in a decrease in intensity of about 1 part of 10,000 - it is very difficult to notice.
The radius of Jupiter/Saturn, on the other hand, is about a tenth of the radius of the Sun, so they will cause a decrease in intensity of about 1 part 100 - this is already easier to notice.
As for the moon - as far as I know, no moon has been discovered on any planet so far - in fact even small planets have barely been discovered (the smallest planet discovered is about 6 times heavier than the Earth) - of course all this when talking about outside the solar system
anonymous:
It is interesting that you ask the first question when one of the links at the bottom of the article is this:
https://www.hayadan.org.il/corot-exo-7b-shay-zuker-0402092/
The answer to your second question is negative. Technology does not yet allow such a discovery.
Are they all gas giants?
Has a planet been discovered that is not made of gas?
Has a gas planet's moon been discovered?
Of course, the previous planets discovered by the spacecraft are also shown there.
Why are there more than 7 in the picture?
Only in space warehouses!
The sale of lands on Corot 3b has begun! Agricultural land, no man's land, land house, Kaka house, toaster triangles!
Special price! Only today, and in the next ten years!
