One of the lightest exoplanets ever discovered, GJ 367b has a surface temperature of over 2,700 degrees Fahrenheit, and orbits a red dwarf star.
The 366 exoplanets were found by an algorithm that searched 800 million images of stars taken by NASA's Kepler Space Telescope in its K2 mission.
The extreme exoplanet is so close to its star that it is the fastest planet of its type ever found.
The space agency used a supercomputer program to confirm 301 suspected new planets, bringing the total to nearly 5,000.
Scientists want to know if life exists in what are known as the Goldilocks zones around the sun's stellar neighbors. How long would getting there take?
The exoplanet orbits its dwarf star in 35 days and has a very cold surface temperature, but astronomers believe it could still host life in its clouds.
By studying 23 white dwarfs within 650 light-years of our sun, researchers have found materials absent from the solar system.
The red-hot distant world could be studied further by the James Webb Space Telescope to reveal more about its atmosphere.
The fact that the solar system could be traveling through a highly magnetized filament in space may also explain mysterious rope-like structures in the sky.
The radio waves are a "spectacle from lightyears away" possibly linked to magnetic interactions between red dwarfs and the undiscovered exoplanets that orbit them.
The planet-spotting method unites the future of astronomy—the Nancy Grace Roman Space Telescope—and its past, a technique used by 19th-century astronomers.
Both planets have nearly twice the radius of Earth with one of the exoplanets possessing over 10 times the mass of our planet.
Researchers who suggest Mars' size could explain why it lost its water are the latest team to consider how Earth's neighbor became the Red Planet.
Changing the definition of habitable zones and the exoplanets that can support liquid water could "majorly" boost our chances of finding life elsewhere, University of Cambridge professor Nikku Madhusudhan told Newsweek.
Our solar system is a relatively calm and ordered place compared to the systems of Sun-like stars that have consumed their own planets.
The existence of the new, distant worlds hundreds of light years away has been confirmed, based on data from the retired Kepler space telescope.
Red dwarfs often shoot out dangerous flares, but scientists have discovered their planets may be lucky enough to avoid them.
Scientists want to study the exoplanet, named Kepler-1704b, further after observing its highly eccentric orbit around its host star.
The unique planet orbits a sun-like star around 50 light years away from Earth, and has a mild atmospheric temperature.
Cesar Rubio, one of the citizen scientists behind the planets' discovery, said his seven-year-old son also has a passion for the cosmos.
The star system contains at least three planets that supposedly lie in a region known as the habitable zone.
"It's incredible to be able to make these kinds of discoveries," said researcher David Armstrong.
Determining the abundance of Earth-like planets is one of the major goals of planetary science.
"Maybe Kepler-88 d is the new supreme monarch of this planetary empire, the empress," said astronomer Lauren Weiss.
"This is comparable to several musicians beating distinct rhythms, yet who beat at the same time at the beginning of each bar," said researcher Nathan Hara.
"This intriguing, distant world gives us even greater hope that a second Earth lies among the stars, waiting to be found," said an associate administrator at NASA.
Temperatures on the day side of the planet—which perpetually faces its star—are hot enough to vaporize iron.
"There is a reasonable chance that the planet hosts a large ocean underneath the atmosphere at pressures and temperatures similar to those in the Earth's oceans," researcher Nikku Madhusudhan said.
The planet is located around 1,000 light-years from Earth and experiences average temperatures of more than 1,800 degrees Fahrenheit.
Surface temperatures on KELT-9b can reach up to 7,800 degrees Fahrenheit, making it the hottest known exoplanet.
