TOI 700 e has been confirmed orbiting inside the habitable zone of its star, TOI 700. TOI 700 is a small, cool star (known as an M dwarf star), located around 100 light-years away from us in the Dorado constellation.
Researchers confirmed an exoplanet using NASA’s James Webb Space Telescope for the first time.Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth's diameter.
Two exoplanets – Kepler-138 c and Kepler-138 d – appear to have oceans at least 1,600 km deep. That’s about 500 times deeper than the average depth of Earth’s oceans. However, they could be much warmer and under very high pressure.
The planet, nearly 10 times Earth’s mass, orbits a small, red-orange star about 200 light-years away. This planet is extremely hot, with an estimated temperature of 1,050 Celsius.
While observing the star system HD 23472 , researchers found three super-Earths and two super-Mercuries. This type last of exoplanet is still very rare—counting these two, there are only eight known super-Mercuries.
A new study suggests that many more planets may have large amounts of water than previously thought - as much as half water and half rock. All that water is probably embedded in the rock, rather than flowing as oceans.
The astronomers underlined that the star, these planets are orbiting is the second-coolest star found to host planets after TRAPPIST-1. They added that their finding is the second-most favorable habitable-zone terrestrial planet known so far.
The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system.
This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet.
It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. An exoplanet is just 100 light-years from Earth
Two new worlds of probable rocky mineral goodness have just been found orbiting a star close to our own cosmic neighborhood.
Scientists have discovered a Super-Earth that is four times the mass of our planet and takes just 10.8 days to complete a whole year.
TESS reached a milestone. We now have over 5,000 exoplanet candidates. Scientists have a lot of work to do confirming them.
Using telescopes from around the world, a team of astronomers recently discovered 70 additional free-floating planets (FFPs), the largest sample of “Rogue Planets” discovered to date in the Milky Way.
Astronomers and geologists have recently concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks not found anywhere in our Solar System.
