Exoplanets discovered by nasa8/9/2023 ![]() ![]() Astronomers estimate that the exoplanet is about 15 million to 20 million years old, which means it’s a relatively young world compared to Earth, which is 4.5 billion years old. Keck Observatory The movement of the extrasolar planet AF Lep b (white spot at about 10 o’clock) around. The planets range in size from mostly rocky super-Earths and fluffy mini-Neptunes, to Jupiter-like giants. TESS is in the midst of surveying around 200,000 bright nearby stars with the aim of. The total known planet count beyond our solar system is now more than 3,700. TOI-4127 b was discovered by a team of astronomers using NASA's Transiting Exoplanet Survey Satellite (TESS). New era of exoplanet discovery begins with images of Jupiters younger sibling. NASA said the Webb telescope will be able to glean new details about HIP 65426 b, including a more precise measurement of its mass and age. New era of exoplanet discovery begins with images of Jupiters younger sibling by W. Just last month, NASA’s Kepler telescope discovered 95 new exoplanets beyond our solar system (on top of the thousands of exoplanets Kepler has discovered so far). The gas giant is up to 12 times the mass of Jupiter and its orbit is around 100 times farther from its host star than Earth is from the sun. New data from NASA's James Webb Space Telescope (JWST) shows that the atmosphere of a rocky exoplanet in the TRAPPIST-1 system is either non-existent or incredibly thin, making it unfavorable. How many exoplanets are there To date, more than 5,000 exoplanets have been discovered and are considered 'confirmed' out of the billions in our galaxy alone. The exoplanet is located about 355 light-years away from Earth and was first discovered in 2017, according to NASA. Hinkley led the observations of HIP 65426 b with an international team.

"This is a transformative moment, not only for Webb but also for astronomy generally," Sasha Hinkley, an associate professor of physics and astronomy at the University of Exeter in the United Kingdom, said in a statement. The observations are notable, however, because they hint at how the Webb telescope could be used to search for potentially habitable planets elsewhere in the universe. ![]()
