The exoplanet SPECULOOS-3b was discovered by Initiative scientists Speculoos (The Search for Planets Obscuring Ultracool Stars) brings together astronomers from MIT and the Universities of Liège, Birmingham, Cambridge and Bern. The team’s goal is Searching for exoplanets orbiting very cold dwarf stars Using a network of robotic telescopes on Earth and space observatories.

This limits the field of observation only to relatively close objects, but it turns out that it is Even close to our planet, you can find exoplanets orbiting cool red dwarfs. This particular star is more than two times cooler than our Sun, and is also ten times less massive and 100 times less luminous. It was not easy to detect due to the low temperature (An object that does not emit heat into space is difficult to see with ground-based observation instruments.)

The rest of the materials are under the window with video

Therefore, scientists need to monitor data from telescopes for several weeks. Observing each star individually to detect the movement of the planets. SPECULOOS-3b is the second exoplanet discovered by humanity orbiting an ultracool red dwarf star. As Amory Triwood, professor of exoplanetary science at the University of Birmingham, notes:

He adds that as well These stars generate less heat and are smaller than objects such as the SunBut they are more than 100 times longer in age – about 100 billion years – and are expected to be the last stars to shine in the universe. Such a huge age suggests that life could develop on planets orbiting such objects.
