Astronomers have already discovered More than 4000 planets It falls out of our system. However, the latest discovery by scientists from the University of Hawaii may change the understanding of how planets form, the portal wrote SciTech Daily.
They managed to discover one of the smallest planets we have ever seen. It is referred to as 2M0437b and was formed relatively recently. Perhaps most amazing is the fact that they can observe it live. Discovering the planet ‘in its diapers’ not only helps us understand how planets form, But also how it develops and shaped over time. In addition, we can learn something about how our system came to be.
The author of the new work, which was published in Monthly notifications of the Royal Astronomical Society, Eric Gidus.
Astronomers estimate that the planet is several times larger than Jupiter, and It arose only a few million years ago, Which is really a short time considering the space scale. By comparison, our solar system is 4.5 billion years old.
The planet immediately after its formation
The interesting thing is that The planet has been hot since its inception. The planets consist of a protoplanetary disk, which is a glowing ring of gas and dust around a young star. The birth of a planet begins with the packing of several grains of dust, and gradually the planet’s seed is packing more and more matter.
The planet and its parent star lie in a region where many new stars are forming. This region is called the Taurus Molecular Cloud. At the same time, it is estimated that the planet is located in An orbit much larger than the planets of our system. The distance of a planet from a star can be about 100 AU (Editor’s note: The astronomical unit is the Earth’s distance from the Sun).
Planet 2M0437b was first observed in 2018, and the object was carefully observed over the next few years. It was the goal of the scientists Observe the location of the planet and make sure it is a planet orbiting a star and not a distant object. It took three years for astronomers to confirm it.
“In order to confirm the existence of this planet, we needed the two largest telescopes in the world,” said study co-author Michael Liu.
More notes will follow. The research will include the Hubble Space Telescope, as well as the upcoming space telescope James Webb Telescope. It is the new generation of telescopes that can help astronomers discover more details about the planet. The team hopes They were able to analyze the gases in the planet’s atmosphere, but also whether the planet has a disk of matter around it, from which the moon will form.
The star around which the planet orbits cannot be observed with the naked eye. Before dawn, the system was located almost exactly over Hawaii, North of the star Aldebaran and east of the constellation Pleiades.
