NASA researchers discovered new planets in old Hubble Space Telescope photographs from 1998. The astronomers found evidence of 2 new planets not previously identified in photographs. These planets are far outside the solar system, so they are considered difficult to discover.
NASA researchers discovered new planets in old Hubble Space Telescope photographs from 1998. The astronomers found evidence of 2 new planets not previously identified in photographs. These planets are far outside the solar system, so they are considered difficult to discover.
The discovery gives astronomers an advantage in researching the findings, since it is now possible to compare the data from more than a decade ago, with recent data regarding the locations and orbits of the stars. These data over the years, make it possible to track the development or changes of the routes.
In systems consisting of several massive planets, there is the possibility that the gravitational forces of the planets will affect each other, as well as their sun, so the calculations of the orbits have a decisive effect.
"From the Hubble images, we can determine the shape of the orbits. These help us in evaluating the stability of the system and in calculating other properties such as the masses of the planets," says Rami Sommer, from the Space Telescope Science Institute in Baltimore.
Somer plans to re-examine and analyze 400 additional photographs of stars in the NASA archive, using the same technique, which improves image quality 10 times over previous methods used.
"We wanted to re-examine surveys of nearby and young stars, because there is a greater chance of detecting planets in these images," says Laurent Pouillet, of the NASA research team. "Images with evidence of a lot of dust around the stars are also good candidates, since such areas are a favorable place for star formation."

Gali my dear, absolutely.
interesting.
What speed did knowledge get here... I wrote in a comment in my article that science moves faster than the speed of light...
