About 2, years later, in the 16th century, the Italian philosopher Giordano Bruno suggested something similar. Scientists now know that both Metrodorus and Bruno were essentially correct. Today, astronomers like me are still exploring this question, using new tools. That evidence is based on the discoveries made by the Kepler space telescope , launched by NASA in For four years, the telescope stared continuously at a single region of space within the constellation Cygnus.

Kepler had 42 cameras on board, similar to the kind of smartphone camera that you use to take pictures. This artist's illustration shows exoplanet Ross b, with its red dwarf host star in the background. The planet is only 11 light-years from our solar system. It is now the second-closest temperate planet to be detected, after Proxima b.

WASPb, light-years away, is considered a hot Jupiter-like planet. It has a greater mass and radius than Jupiter, making it "puffier. NASA's Kepler space telescope team has identified more planet candidates, 10 of which are near-Earth size and in the habitable zone of their stars. It is an "iceball" planet with temperatures reaching minus degrees Fahrenheit.

LHS b is located in the liquid water habitable zone surrounding its host star, a small, faint red star named LHS The planet weighs about 6. Depicted in blue is the atmosphere the planet may have retained. It is similar in size to Earth, is a little cooler than Earth's temperature and is in the habitable zone of the star, meaning liquid water and even oceans could be on the surface.

The proximity of the star gives the sky a salmon hue, and the other planets are so close that they appear in the sky, much like our own moon. Artist's conception of the binary system with three giant planets discovered, where one star hosts two planets and the other hosts the third.

The system represents the smallest-separation binary in which both stars host planets that has ever been observed. This artist's impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to our solar system.

An artist's rendering shows Earth-sized exoplanets TRAPPIST-1b and 1c in a rare double transit event as they pass in front of their ultracool red dwarf star, which allowed Hubble to take a peek at at their atmospheres. Out of a new discovery of exoplanets, astronomers found four similar in size to Earth that are orbiting a dwarf star. Two of them have the potential to support life. The craft depicted in this illustration is the NASA Kepler Space Telescope, which has helped confirm the existence of thousands of exoplanets.

This artist's impression shows a view of the triple-star system HD from close to the giant planet orbiting in the system. Located about light-years from Earth, the planet is about 16 million years old, making it also one of the youngest exoplanets discovered to date. An artistic impression of the planet Keplerb, which is nearly identical to Jupiter in both size and mass.

The planet is expected to be roughly similar in appearance. But it is much warmer: Keplerb is in the habitable zone. HDb is a gaseous planet 11 times more massive than Jupiter. The planet is believed to have formed in the center of its solar system, before being sent flying out to the edges of the region by a violent gravitational event.

Keplerb orbits at a distance more than 20 times closer to its star than Mercury is to our own sun. Daytime temperatures exceed 1, degrees Celsius 2, degrees Fahrenheit , which is hotter than lava flows on Earth. This Jupiter-like planet in the HD system, light-years from Earth, has three suns. The main star is similar in mass to our own Sun. Keplerb is a Uranus-sized transiting exoplanet with the longest known year, as it circles its star once every days.

The planet orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1, light-years from Earth in the constellation Lyra. Astronomers discovered two planets less than three times the size of Earth orbiting sun-like stars in a crowded stellar cluster approximately 3, light-years from Earth in the constellation Cygnus.

This artist's conception shows a hypothetical planet with two moons orbiting in the habitable zone of a red dwarf star. The majority of the sun's closest stellar neighbors are red dwarfs. Keplerf was the first validated Earth-sized planet to be found orbiting a distant star in the habitable zone.

This zone a range of distance from a star where liquid water might pool on the planet's surface. Keplerc is a super-Earth-size planet similar to Venus. The planet is found in the habitable zone of a star like our sun, approximately 2, light years from Earth in the constellation Cygnus.

The Kepler system formed when the Milky Way was just 2 billion years old. An illustration that shows what it might look like to stand on the surface of Keplerb. The planets are relatively close together, too. It has also made a list of more than 3, additional potential exoplanets that astronomers need to study more carefully to be sure that they are indeed planets. While Kepler primarily searched within one particular patch of the sky, TESS is observing the entire sky to locate thousands of planets orbiting the nearest and brightest stars.

The James Webb Space Telescope, set to launch in , will also observe many of the exoplanets we have discovered and help scientists reveal details about these distant worlds. Who knows? One day, by studying exoplanets and distant solar systems, astronomers hope to answer the intriguing question: Is there life elsewhere in our galaxy? The Short Answer:.
