Could there be evidence of extraterrestrial life? This is known about it

In an ever-expanding universe, the search for extraterrestrial life has captivated humanity’s imagination for centuries. German astronomer Lisa Kaltenegger, leader in the field of exoplanet modeling and characterizationhas dedicated his career to this exciting challenge.

Founder of Carl Sagan Institute, Kaltenegger tirelessly promotes planetary exploration beyond our solar system in search of signs of life.

Recently, Kaltenegger has taken a new step in his mission with the publication of his book titled Alien Earths. In this work, the scientist exposes her belief in the possibility of finding extraterrestrial life formssupported by increasingly closer evidence.

Their focus is on the search for “biosignatures”, signs of life in the atmospheres of distant planets. These biosignatures are gases similar to those produced by organic processes on Earthsuch as oxygen and methane, and represent tangible hope in the search for life beyond our planet.

For Kaltenegger, the key is in the technology available, such as the James Webb Space Telescope, a fundamental tool in the exploration of thousands of worlds that were previously inaccessible. In his words, we are in a “golden age of exploration” with the ability to explore a wide variety of planets and look for signs of life they might harbor.

In her book, the astronomer not only talks about the possibility of finding planets similar to Earth, but also addresses the need for scientific rigor in the search for extraterrestrial life. He warns against overinterpreting UFO sightings and highlights the importance of accurate and verifiable data in this investigation.

Kaltenegger reveals that he is focusing his efforts on systems such as the Trappist-1 star, where it is believed that conditions could be conducive to the existence of life. With the development of technologies such as the Habitable Worlds Observatory, the scientist seeks to pave the way for future generations in the search for life beyond our planet.
