Our Sun has a twin: this new star highlights the behavior of the Sun in its youth

The Sun has fueled life on Earth for millions of years, burning to produce constant energy as astronomers study hidden surface mysteries and coronal differences. However, very little is known about its beginnings in our solar system and how it led to the emergence of life on the planet.

A new star detected by NASA could offer a glimpse of our own Sun and reveal how it all began. The young star, just 30 light years away, could function as a time machine and light up the Sun and tell us about its youth in the system as it developed over billions of years.

Research published in The Astrophysical Journal indicates that the study of the star provides more in-depth information on the impact of coronal emissions, stellar winds and atmospheric erosion of the first exoplanets of Venus, Earth, Mars. and young Earth.

Our Sun has a twin

While it is impossible to go back in time and examine the conditions that favored life on Earth, studying the stars near our solar system can help improve knowledge about how life began. . The Milky Way has more than 100 billion stars, and one in ten shares characteristics with our Sun, and many are in the early stages of development.

Nicknamed Kappa 1 Ceti, the star is estimated to be between 600 and 750 million years old, roughly the same age as our Sun when life developed on Earth. According to NASA, because of its proximity, it’s like a neighbor who lives down the street next door (in cosmic terms). It also has a similar mass and surface temperature to our Sun, making it a “twin” of our young star around the time life first appeared on Earth, and an important target for study.

Researchers designed a model to predict some of the most important, but difficult to measure, features of Kappa 1 Ceti, drawing on the Hubble Space Telescope, NASA’s Transiting Exoplanet Survey satellite and NICER missions, and the XMM -Newton from ESA.
