NASA and ESA data reveal a giant, extreme planet with the power to rejuvenate its parent star next to it and distort astronomical measurements.
According to a group of scientists led by Dr. Nikolata Ilic of the Leibniz Institute for Astrophysics in Potsdam, Germany, these are the “Hot Jupiter” located extremely close to its parent star.
Hot Jupiter is one planets outside the solar system has been found quite a bit in the hunts of NASA, ESA (the American and European space agencies) and some other space agencies, because it is very large and quite easy to observe compared to other types of aliens on another planet.

These are giant gas planets, as large or larger than our Jupiter, but very hot because they are located close to the parent star. These are worlds that are unlikely to have life, but are still of great concern because they have many strange properties and can affect the formation of other planets in the system.
In new research, astronomers have discovered that some calculations about star systems with hot Jupiters can be misleading because the parent star appears “younger” than usual.
“By comparing a star with a nearby planet to a twin without a planet, we can study differences in the behavior of stars of the same age” – Sci-News cites the analysis by co-author Katja Poppenhaeger, also of the Leibniz Institute for Astrophysics in Potsdam.
They examined 10 pairs of binary stars from data from NASA’s Chandra X-ray Observatory and six other pairs from ESA’s XMM-Newton Observatory. The results show In each pair, the star with hot Jupiter always appears younger than the twin.
The reason is that the tidal force is too strong One of these hot gas giants negatively impacted its parent star, causing it to spin faster and become more active, as a way of freezing time.
Just like people, young stars often become fast and dynamic, slowing down as they get older. Therefore, if we only apply conventional observational formulas, we might mistake the “mother” of these hot Jupiters as appearing younger than she actually is.
This discovery indicates necessary changes in astronomical observations that scientists will need to consider in their journey to study planetary systems with hot Jupiters in the future, while providing additional interesting pieces to the puzzle. It is assumed that planets can also regulate their parent planets. stars in mysterious and interesting ways.
