American researchers have found a new direction in the search for “dark matter”: It is in the hearts of gas giants.
The authors from Ohio State University (USA) believe that dark matter is made up of individual particles and these particles can sometimes crash into giant planets and then penetrate deep inside the planet. , accumulates and continuously collides with each other, destroys each other and generates heat.

Speaking to Live Science, astrophysicist Juri Smirnov, one of the authors, said the self-destruction of dark matter lurking in the “hearts” of gas giants could be detected by Consider the unusually hot cold planets.
First, we need to find old planets that have been knocked out of their own stellar systems and no longer heated, according to the Physical Review Letters; or lower star but more advanced than planets, known as brown dwarfs.
Next, we need to classify which of the planets have dark matter inside by noticing infrared luminosity. With no heating and no fusion reaction to self-heat, these celestial bodies need something else to produce infrared radiation.
The study is intended to provide a tentative mission for the state-of-the-art James Webb space telescope, which NASA plans to launch in October this year.
Dark matter is thought to make up at least one-sixth of the matter in the universe, but is extremely ghostly, mysterious and invisible. However, many times astronomers have “seen” it through its interactions on other surrounding objects, in the same way that ghosts shove foreign objects in fiction.
