NASA has been exploring space for many years, discovering new planets, moons, and stars. Recently, they announced the discovery of a new planet and named it TOI 700 d.
The Discovery of TOI 700 d
The planet was discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) in January 2020. TOI 700 d is about 100 light-years away from Earth and is located in the constellation Dorado.
TESS is a space telescope that is designed to search for exoplanets, which are planets outside our solar system. It searches for exoplanets using the transit method, which involves measuring the tiny dips in the brightness of a star when a planet passes in front of it.
TOI 700 d is an exoplanet that is about the size of Earth and is located in the habitable zone of its star. The habitable zone is the area around a star where the temperature is just right for liquid water to exist on a planet's surface.
Scientists believe that TOI 700 d could have an atmosphere similar to Earth's and could potentially support life.
The Naming of TOI 700 d
When a new planet is discovered, it is given a temporary name based on the telescope that discovered it and its location in the sky. TOI 700 d was initially named TOI 700 because it was the seventh planet discovered by TESS in the constellation Dorado.
However, once it was confirmed that TOI 700 d was a planet and not a false positive, NASA held a naming contest for the planet. The contest was open to students in grades K-12 and received over 28,000 entries.
The winning name was submitted by a 17-year-old student named Wolf Cukier. He suggested the name "Kalamari," which is the Hawaiian word for seeker, explorer, and messenger. However, NASA officials decided to name the planet TOI 700 d instead.
Potential for Life on TOI 700 d
TOI 700 d is the first potentially habitable exoplanet discovered by TESS. Its location in the habitable zone and its size make it a promising candidate for further study.
Scientists are already planning to use the James Webb Space Telescope, which is set to launch in 2021, to study the planet's atmosphere and search for signs of life.
However, it is important to note that just because a planet is in the habitable zone and has the potential to support life, it does not mean that it actually does. There are many factors that contribute to a planet's ability to support life, including its atmosphere, magnetic field, and proximity to its star.
Conclusion
TOI 700 d is a new exoplanet discovered by NASA's TESS telescope. It is about the size of Earth and is located in the habitable zone of its star. Although it was not named Kalamari as suggested by the winning entry of the naming contest, it still holds promise as a potential candidate for further study and the search for life beyond our solar system.
