NASA’s TESS discovers a new world between Earth and Venus.
Washington: Scientists of America’s world famous space agency NASA have surprised the whole world by discovering another interesting world between Earth and Venus. Two international teams of astronomers of NASA’s TESS (Transiting Exoplanet Survey Satellite) have discovered a new planet between Earth and Venus, only 40 light years away, using observations of many other facilities. Scientists have called it a very interesting new world between Venus and Earth. It will be even more interesting to know whether humans and other creatures live in this new world like Earth? Are scientists going to reveal the secret of this new world soon? … Such questions have started coming to people’s minds as soon as the new world is discovered.
Many factors have been found in this new world discovered between Earth and Venus, which scientists say are suitable for further study using NASA’s James Webb Space Telescope. Let us tell you that TESS can closely observe a large part of the sky at the same time in a month. It can also track the changes in the brightness of thousands of stars at an interval of just 20 seconds to 30 minutes. Capturing the transit of stars in the world of orbiting planets, finding out the reasons for their brief and regular dimming is one of its primary goals.
What is special in this new interesting world
“We have discovered the closest, transiting, temperate, Earth-sized world to date. However, we do not yet know whether it has an atmosphere. We think of it as an exo-Venus, with a size and energy similar to that of our neighboring planet in the Solar System from its star,” said Masayuki Kuzuhara, a project assistant at the Astrobiology Center and a professor at the University of Tokyo who co-led the project with Akihiko Fukui. However, it is not yet known who lives in this new world. Scientists are eager to explore the presence or possibility of life in this new world.
42 degrees is the temperature of the interesting world
He said that this host star is cool, red and dwarf which is located about 40 light years away in the constellation Pisces. It is called Gliese 12. At the same time, the newly discovered world has been named Gliese 12b. The size of the star is only 27% of the size of the Sun, with a surface temperature of about 60% of that of the Sun. It orbits every 12.8 days and its size is equal to or slightly smaller than Earth or Venus. If it is assumed for the time being that it has no atmosphere (which is yet to be discovered.) Then the surface temperature of this new planet is estimated to be about 107 degrees Fahrenheit (42 degrees Celsius).
Astronomers told a surprising thing
Astronomers say the small size and mass of red dwarf stars make them ideal for finding Earth-sized planets. A smaller star means more blur for each transit and a lower mass means an orbiting planet can cause a larger wobble, known as the star’s “reflex motion.” These effects make it easier to detect smaller planets. The lower brightness of red dwarf stars means their habitable zones — the range of orbital distances where liquid water could exist on a planet’s surface — lie closer to them. This makes it easier to detect transiting planets within habitable zones around red dwarfs than around stars that emit more energy.
The planet of the new world receives energy from its star
The distance separating Gliese 12 and this new planet (Gliese b) is only 7% of the distance between Earth and the Sun. Just as the Earth receives energy from the Sun, this planet receives 1.6 times more energy from its star than Earth and Venus. Shishir Dholakia, a doctoral student at the Centre for Astrophysics at the University of Southern Queensland in Australia, said, “Gliese 12 b represents one of the best targets to study whether Earth-sized planets orbiting cool stars can retain their atmospheres, which is an important step to advance our understanding of habitability on planets in our galaxy.
He co-led a separate research team with Larissa Palethorpe, a doctoral student at the University of Edinburgh and University College London. Both teams suggest that studying Gliese 12b could help unlock some aspects of the evolution of our own solar system.
