Astronomers find potentially habitable ‘super-Earth’ exoplanet

Press/Media: Relating to Research

Description

Astronomers have discovered three potential “super-Earth” exoplanets orbiting a relatively nearby orange dwarf star, marking an important development in the search for habitable planets.

This groundbreaking discovery was made by an international team of researchers, including Dr Ancy Anna John, a post-doctoral researcher from the School of Physics and Astronomy at the University of St Andrews.

The exoplanets are orbiting Star HD 48948, located approximately 55 light-years from Earth. These planets revolve around their host star in 7, 38, and 151 Earth days, respectively. Notably, the outermost exoplanet candidate resides in the habitable zone of its host star, where conditions could allow liquid water to exist without boiling or freezing. This region, often referred to as the Goldilocks zone, is considered ideal for potentially supporting life.

    Dr Anna John from the School of Physics and Astronomy at St Andrews said: “Providing insights to the human race’s long-standing question, “Are we alone?” is always thrilling. The discovery of these three super-Earth companions around a nearby star, is a crucial stride towards the search for cosmic twin, particularly the outer planet that is found in the habitable zone, orbiting the star in every 151 earth days. This planet emerges as a promising target for our future missions that are devoted to finding habitable worlds, such as NASA’s Habitable Worlds Observatory (HWO), the Habitable Expolanet Observatory and the European Space Agency’s Large Interferometer For Exoplanets (LIFE) Mission.”
