NASA TESS Discovers Two New Huge Extrasolar Planets

Must read

In its first published paper, NASA’s TESS mission has discovered two new massive extrasolar planets. These two new planets are named TOI-125 and TOI-1338 b, respectively. However, the discovery of these two new planets has some limitations. First, the data presented here contains an order-of-magnitude more false positives than vetted detections. The authors’ analysis is beyond the scope of this paper, but TESS has the potential to significantly increase the number of eclipsing quadruple systems.

TOI-125

The NASA TESS spacecraft has discovered two new huge extrasolar planets, confirming the existence of at least one exoplanet. The mission has been successful in discovering over two hundred exoplanets, and the data collected has revolutionized stellar astrophysics. TESS provides important data on star sizes, starspots, and stellar properties. This information can be used to characterize exoplanets orbiting these stars, as well as improve our knowledge of stellar structure and evolution.

The discovery is the latest addition to the long-term study of exoplanets. Using a spectrograph and a computer model, the team was able to confirm the discovery of TOI-5153 b and TOI-5153 c. Both planets are over three times as massive as Earth. Both orbit their stars at a distance of 0.16 AU. The distance of their systems is 1270 light years, and both are classified as hot Jupiters. The scientists believe that they are rocky exoplanets.

TOI-1338 b

Astronomers have confirmed the existence of two huge extrasolar planets by observing starlight passing through the atmospheres of these newly discovered planets. Known as TOI-1518 b and TOI-1518 c, these planets are super-Earths that are around 1.5 and 1.2 times larger than the Earth, respectively. Both worlds are too hot to support life. The temperatures of these planets may be high enough to keep them from melting or forming an atmosphere.

After two years of observations, NASA’s TESS mission has successfully completed its primary mission. The spacecraft has identified thousands of planetary candidates and nearly two thousand candidates for confirmation. As of September, TESS has confirmed the discovery of two new giant extrasolar planets that are closer to Earth than Kepler did. Its results so far have been promising. NASA will announce the discovery of the two new planets in the coming months.

TOI-125 b

Researchers have just announced the discovery of two new huge extrasolar planets around two nearby stars, both red dwarfs. The discovery is a triumph for astronomical discovery in the past 50 years, especially considering that both planets orbit faint stars. The discovery of two new huge planets will help astronomers answer the question of how common life may be in the universe. And while the discovery is exciting, it doesn’t mean that Earth-like planets exist in the universe.

The first of the two planets is called TOI-1338 b, and it resembles the sand world Tatooine from Star Wars. It is roughly 1,300 light-years away and is a super-Earth. The second planet, named LHS 3844 b, orbits its star in only 11 hours. The temperature on the surface of TOI-1338 b is comparable to that of Earth’s. Another planet in the system is TOI-1690 b, or WD 1856 b. The planets were discovered through NASA’s Transit Object Survey Satellite (TESS).

TOI-125 c

The discovery was made by a team of astronomers led by Rafael Luque, director of the Institute of Astrophysics of Andalusia and a professor at the University of Chicago. The team used data from NASA’s TESS mission to come up with their discovery. The findings were presented at the meeting of the American Astronomical Society in Pasadena in June 2022.

TOI-451 b orbits its star every 1.9 days and is roughly three times larger than Earth. Its mass is two to 12 times that of Earth. TOI-451 c orbits its star every nine and a half days and weighs between four and nineteen Earth masses. Both TOIs are likely remnants of gas giant planets. While they are still largely unexplored, this discovery builds on previous discoveries.

TOI-1338 b and TOI-1518 b are super-Earths that are 1.2 and 1.5 times the size of our planet. While neither world is likely to support life, the temperature on both of them is much warmer than on Earth. In fact, b is about eight hundred and fifty degrees Fahrenheit and TOI-1690 b is five hundred and thirty degrees Celsius. The exact temperatures of these planets depend on their atmospheres.
