Scientists have recently discovered a 10-billion-year-old “super-Earth” in the Milky Way galaxy. A study has recently revealed a 10-billion-year-old “super-Earth” in the Milky Way galaxy, and scientists believe it is likely that Life has appeared on the rocky planet.
A new study presented at the 237th meeting of the American Astronomical Society shows that scientists have discovered a “super-Earth” that is about 10 billion years old. The planet, TOI-561b, is about 280 light-years from Earth in the southern sky in the constellation Sextans, and is 1.45 times the size and three times the mass of Earth.
Its host star, TOI-561, an orange dwarf, is also about 10 billion years old, making it one of the oldest known stars in our galaxy.
Scientists believe that the Milky Way is about 12 billion years old, and that this “super-Earth” was created almost at the beginning of the galaxy’s existence.
TOI-561b is one of the oldest rocky planets ever discovered,” said study leader Lauren Weiss, a postdoctoral researcher at the University of Hawaii. Its existence suggests that the universe has been continuously producing rocky planets since its birth 14 billion years ago.”
The planet takes 10.5 hours to orbit its host star in one week, in the same pattern as the Moon orbits the Earth, always with only one side facing its host star. This means that one side of the planet is always day and the other is always night. Researchers estimate that the night side of the planet may be a rocky terrestrial surface.
In addition, the newly discovered “super-Earth” is located in the thick disk region of the Milky Way, which is unusual.
Researchers say that most spiral galaxies like the Milky Way have two disks: a thin disk and a thick disk. The stars in the thick disk region are relatively older, meaning that the rocky planet emerged and began evolving at the birth of the universe more than 10 billion years ago.
Scientists believe it is likely that there was life on this planet billions of years ago.
This suggests that rocky planets have been produced over the past 10 billion years, and even over the course of the galaxy’s entire 12-billion-year history,” Weiss said. Imagine what kind of history there is on top of a rocky planet that is 10 billion years old. I’d love to know.”
Weiss is responsible for the study, which will be published in the February issue of The Astronomical Journal.
So far, scientists have discovered many “super-Earths. Bjorn Benneke, an astronomer at the University of Montreal, Canada, has said, “Our ultimate goal is to find life on other planets and prove that we are not alone.”
