2022 has been a very productive year in terms of space sciences. Many countries and scientists working in this field have made extremely important discoveries about space. In particular, the James Webb Space Telescope, which was placed into the atmosphere by the US National Aeronautics and Space Administration (NASA), has allowed us to witness breathtaking cosmic landscapes that mankind has never seen before. However, the most exciting developments in space science took place in 2023, not 2022. NASA recently announced that it had discovered a “habitable” planet 100 light years from Earth! Let’s look at the details together…

“Extraterrestrial life” has long been one of the most important areas of study in astronautics!

Especially with the development of technology in recent years, there has been a marked increase in the search for extraterrestrial life. The search for extraterrestrial life, which was once mentioned only in science fiction, today is one of the most important areas of study of space exploration.

Many institutions and organizations working in the space sciences are working on technologies that will allow humanity to live on extraterrestrial planets, while continuing the search for planets similar to Earth and habitable. Undoubtedly, NASA is one of the most important institutions that conducts research on extraterrestrial life.

NASA has announced that a habitable planet has been discovered 100 light-years from Earth!

The planet located in the “habitable zone” of the constellation Dolphin (Dorado) is called “TOI 700 e”. The habitable zone refers to the distance between an exoplanet and its orbiting star, the ideal distance at which water can be detected on a planet’s surface. On the other hand, it is argued that the planets in these regions may provide other conditions necessary for life. NASA researcher Emily Gilbert said of this important discovery:This is one of the few systems known to us with several small habitable planets.uses a phrase.

TOI 700 e detected by the Transiting Exoplanet Survey (TESS) satellite


The satellite, called TESS, has 4 high-tech observation instruments that can make continuous observations for 27 days, and each of them can see a quarter of the space in the direction it is looking. TESS, which specifically observes planets outside the solar system, attempts to detect corresponding planets in a so-called “transitional” position.

The transition position is used to indicate when an exoplanet passes in front of its orbiting star. By measuring changes in the brightness of a star during a transit, scientists can obtain various data about the structure of the planet taken at the time of the transit.

TOI 700 e is almost the same size as Earth


TOI 700 e is said to be 95 percent the size of the Earth. However, the planet completes its revolution around the star in 28 days. However, the new planet that is considered habitable has a surface structure full of rocks!

A system called TOI 700 contains 4 different planets in the habitable zone.

TOI 700 d

Prior to habitable planet TOI 700 e, three different habitable planets were found in the same star constellation named TOI 700 b, c, and d. However, TOI 700 e is distinctly different from other planets found in its sister system. The planet is about 10 percent smaller than the previously discovered planet, named TOI 700 d. The scientists say the discovery is extremely important as it could help the TESS telescope to discover “smaller Earths” in the future.
