The science of planets outside the solar system is flourishing thanks to the genius of Michel Mayor, and the device he built

Says Prof. Zvi Maza from the School of Physics and Astronomy at Tel Aviv University, and his colleague Mayur and Didia Kilo who jointly won half of the Nobel Prize in Physics for 2019 in an interview with the Hidan website.

"The unique device built by the Nobel laureate Michel Maior to locate planets advanced us by giving us our place in the universe." Says Prof. Zvi Maza from the School of Physics and Astronomy at Tel Aviv University, and his colleague Mayur and Didia Kilo who jointly won half of the Nobel Prize in Physics for 2019 in an interview with the Hidan website.

 

"I worked with Prof. Mayur even before the discovery, and among other things I was among those who suggested that he search for planets outside the solar system... He built the only device in the world at the time that led in 95 to the discovery of the first planet outside the solar system. He worked with his doctoral student Didier kilo."

"Mayo is a wonderful man and also an outstanding scientist who excelled at collecting data and building instruments. He gathered around him experts in optics and built an instrument, which he connected to a telescope that was already outdated in the south of France at the time and began looking for planets. He chose a sample of stars and followed them, trying to detect a change in their brightness when Her planet passes between us. This is how he discovered Pegasi 51, which was the first to be discovered to a whole industry that has been flourishing ever since."

"It turns out that a significant percentage of the stars don't know if it's 100 percent or 50 percent, but it doesn't matter, there are planets around them. This is an innovation of the industry that Mayur was a pioneer in."

According to Prof. Maza, he made a similar discovery six years earlier, but the object he discovered was not yet recognized as a planet "due to unsolved astrophysical questions." Today, by the way, it is recognized as a planet. "Then, in 95 Mayur and Kilo published the article theirs, which was a fantastic discovery and without any question marks, and all this with the help of the device that Michel built, which had a precision that had not been equaled until then.

"It is important to note that all the space telescopes dedicated to the discovery of planets outside the solar system, led by Kepler, would not have come into existence if not for the discovery of the two winners. It is a fact that human society finds it very right to devote such large resources to the search and characterization of planets."

Historical perspective

"In a certain sense, if you look at it from a historical point of view," says Prof. Maza, "you see that in the beginning we thought that the Earth was at the center of the universe and everyone revolved around it. Copernicus came and said that the sun is in the center and the earth is one of the stars You left and then we realized that the sun is not unique and there are billions of suns just in our galaxy and hundreds of billions of galaxies in the universe. And then in 95 it became clear that there was also the error of being a planet around the sun - a cold body that rotates around a burning body that produces energy. This is not unique either. This is the innovation of the new field, another understanding that our place in the universe is not unique."

Will the next step be the discovery of life on planets outside the solar system?

Prof. Maza: The next step is first of all to discover planets that have the conditions to create life with a suitable atmosphere. It is possible that the next step will be to discover life. Astronomers are making rapid progress and within five years it will be possible to analyze the chemical composition of the atmospheres of planets.
