NASA’s TESS Mission discovers exoplanet in our galaxy older than Sun

National Aeronautics and Space Administration’s (NASA) Transiting Exoplanet Survey Satellite (TESS) has found an exoplanet within the Milky Way galaxy. Researchers consider it’s 10 billion years previous, greater than twice as previous as our Sun. The planet named TOI-561b orbiting outdoors our photo voltaic system is 1.5 occasions the scale of the Earth, has extra mass than Earth, however nearly the identical density. The planet orbits round its solar, which is situated within the galactic thick disk, in a short time and completes it in about 12 hours.
The discovery of the planet was made public within the 237th assembly of the American Astronomical Society and later accepted for publication in Astronomical Journal. The assembly was held nearly as a result of Covid-19 pandemic.
The examine additionally mentions that the temperature on the planet’s floor reaches 1,726 levels Celsius which makes it not fitted to habitation.

As per a report by CNN, the rocky planet’s mass, radius and density have been calculated with the assistance of knowledge collected on the WM Keck Observatory in Hawaii. “TOI-561b is one of the oldest rocky planets yet discovered,” University of Hawaii postdoctoral fellow and workforce lead Lauren Weiss mentioned in an announcement. “Its existence shows that the universe has been forming rocky planets almost since its inception 14 billion years ago.”
What makes this ‘Super-Earth’ extra intriguing is its density, contemplating the scale compared to Earth. However, older planets are much less dense owing to the much less amount of heavy metals discovered on them. These parts are discovered on our planet as a result of it was shaped after the Sun exploded in Supernova and distributed these parts into house.

Researchers are additionally within the historical past of the rocky planet because it might have been liveable in some unspecified time in the future in its existence. “Though this particular planet is unlikely to be inhabited today, it may be a harbinger of many rocky worlds yet to be discovered around our galaxy’s oldest stars,” mentioned Stephen Lane, the lead creator of the examine on the University of California, Riverside.
