Are we alone in the universe? Join us as we explore the mysteries of the cosmos and the possibility of life on other planets. In this video, we delve into the exciting world of super-Earths, exoplanets that are larger, more abundant, and potentially more habitable than Earth. These incredible exoplanets offer some of the best chances we have of finding life on other planets.

In the summer of 2022, NASA's Transiting Exoplanet Survey Satellite made a major discovery, the identification of two super-Earths. These exoplanets are larger and more massive than Earth, but smaller than ice giants like Uranus and Neptune. What makes these super-Earths particularly interesting is their location in the habitable zones of their parent stars. This means that they could potentially support life.

Most super-Earths orbit cool dwarf stars, which are lower in mass and have longer lifespans than the Sun. There are hundreds of cool dwarf stars for every star like the Sun, and scientists have found super-Earths orbiting around 40% of the cool dwarfs they have studied. Based on this information, astronomers estimate that there are tens of billions of super-Earths located in habitable zones, where liquid water can exist, in the Milky Way alone.

Super-Earths are also easier to detect and study than Earth-sized planets because they can be seen using the two most common methods for detecting exoplanets which are looking for the gravitational effect on the parent star or observing a brief dimming of the star's light as the planet passes in front of it. These methods are more effective with larger planets.

In fact, Earth may not be the best candidate for life in the universe. Research suggests that long-term habitability on Earth was not inevitable and was simply a matter of chance. This is due to the planet's tectonic activity and changes in the brightness of the Sun, which have caused the climate to shift from extreme heat to extreme cold over time.

According to researchers, larger planets are more likely to be geologically active, which is a characteristic that could promote biological evolution. The most habitable planet would also have roughly twice the mass of Earth and be 20-30% larger in volume.

But how do we even search for life on distant exoplanets? By looking for biosignatures which are byproducts of biology that are detectable in a planet's atmosphere. NASA's James Webb Space Telescope will be able to observe two potentially habitable super-Earths in its first year of operations, as well as the recently discovered super-Earths with massive oceans and the ones discovered in the summer of 2022.

The real game-changers in the search for extraterrestrial life will be the next generation of giant ground-based telescopes which are the 39-meter Extremely Large Telescope, the 30-meter Telescope, and the 25.4-meter Giant Magellan Telescope. These powerful instruments, currently under construction and set to begin collecting data by the end of the decade, will give us the best chances yet of finding signs of life on exoplanets.

Join us as we explore the mysteries of the universe and the possibility of life on other planets. Are super-Earths the key to our future as a species? Let's find out together!

I think it's strange that we are looking for earthlike planets to find extraterrestrial life as if we knew extraterrestrial life needs the same elements as we do. I believe there might be different types of extraterrestrial life that don't need sun, water, or oxygen to live, so we might be not discovering them, cause we ain't looking at the correct places. Extraterrestrial life doesn't need to be made of water, bones, and such... it can be light or anything else we don't even know how to look at even.
