New earth-like planets in our cosmic neighborhood could be habitable

As far as the universe goes, Teegarden's star, a faint red-throated, is almost right next door. Astronomers have discovered two exciting planets located in the star's habitable zone, where they might be liquid water.

A research group led by the University of Göttingen in Germany announced the earth-like exoplanet discovery on Tuesday. The Teegard's star is only 12.5 light-years away from us, but it is very different from our own sun. It is much cooler and dimmer and was not even discovered before 2003.

"The two planets resemble the inner planets of our solar system," says Mathias Zechmeister, lead author of a study of the exoplanets in the journal Astronomy and Astrophysics. They are both slightly heavier than Earth and can be part of a larger system with more planets.

Before we get too excited, it is important to remember that "Earth like" does not guarantee a planet that hosts life.

The discovery took place through the Carmenes project, which focuses on finding exoplanets around small, cool stars. Carmenes had already placed nine other exoplanets.

A fun feature of the planets around Teegarden's star involves the star's special location. Possible foreigners would like to look at our solar system and spot the Earth that passes the sun. This creates a slight damping of our own star, while our planet passes in front of it.

Perhaps at the same time we look at the Teegarden star. Extracts look back on us and wonder if the Earth could sustain life as they know it. In this wide, wonderful universe, this is an opportunity.
