Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years […]

Within the next 20 years, human beings could discover life on other planets. It was this startling prediction—and the subsequent realization that kids sitting in elementary school classrooms

https://en.wikipedia.org/wiki/Extraterrestrial_life
The hypothesis of ubiquitous extraterrestrial life relies on three main ideas. The first one, the size of the universe allows for plenty of planets to have a similar habitability to Earth, and the age of the universe gives enough time for a long process analog to the history of Earth to happen there.

https://science.nasa.gov/exoplanets/search-for-life/
The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don't know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system.

Astronomers and other scientists constantly research and explore space. One of the most intriguing questions they hope to answer one day is whether life exists on other planets. Despite a lot of research in outer space, scientists have not yet been able to find evidence of life forms on any other planet other than Earth.. Earth is very hospitable, which makes living here easy.

The Kepler mission —a space observatory launched by NASA in 1997 to search our galaxy for just these kinds of Earth-like planets—has found one candidate that meets both requirements, Kepler-452b. So the chances of life on another planet are high. However, we have no direct evidence yet of life anywhere other than Earth.

More than 4,900 exoplanets - planets around other stars - have been confirmed to exist in our galaxy, but likely number in the trillions. One of the best tools scientists have to begin narrowing the search for habitable worlds is a concept known as the "habitable zone."

The star is more similar in size to Jupiter and is twice as cold as the sun. Nevertheless, the dwarf star radiates an enormous amount of energy onto the planet's surface due to the planet's extremely close proximity: SPECULOOS-3b circles its star in just 17 hours. One year on the new planet, then, is shorter than one day on Earth.

Pigments that absorb light are helpful to Earthly organisms in ways other than just producing energy. Some protect against the sun's radiation or have antioxidants to help the organism survive extreme environments such as salt concentrations, high temperatures or acidity. There are even photosynthetic pigments that do not produce oxygen at all.
