New data from NASA’s James Webb Space Telescope has revealed that K2-18 b, an exoplanet nearly nine times the size of Earth, could be an example of a theorized class of planets with hydrogen-rich atmospheres, vast liquid oceans and the potential to support life. Observations taken by the telescope detected the presence of carbon-bearing molecules such as methane and carbon-dioxide, according to a NASA press release published on Monday. Astronomers also picked up signs of a molecule called dimethyl sulfide (DMS) – which, on Earth, is only produced by living things. K2-18 b is an exoplanet orbiting a dwarf star roughly 120 light years away from Earth in the constellation of Leo. It is categorized as a sub-Neptune, a class of planets that are between the size of Earth and Neptune and common in the universe, although not in our solar system. Scientists have known about K2-18 b for a while, with initial observations taken by NASA’s Hubble Space Telescope, but these new observations taken with the James Webb Telescope have provided details that astronomers had previously only wondered about. "Our findings underscore the importance of considering diverse habitable environments in the search for life elsewhere," Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of a paper announcing these results, said in the release. "Traditionally, the search for life on exoplanets has focused primarily on smaller rocky planets, but the larger Hycean worlds are significantly more conducive to atmospheric observations."

Can't stop reading about planets and exoplanets.

Nasa has such an amazing site. You can pick a planet and spin it around, check the (solar) star system, ser the other planets in it, look at the moons, and get up close with the star, and even see the whole galaxy and more!

Have fun

Exoplanet Heating

WASP-96B is a tidally-locked exoplanet between the size of Saturn and Jupiter. This hot, massive planet lies close to its star, orbiting in less than three-and-a-half Earth days.  (Image and research credit: J. Skinner et al.; via APS Physics) Read the full article

The habitable area of a solar system is called "the Goldilocks Zone" by astronomers because we're gonna wait til the aliens leave, then break in and use all their stuff.

i love when space headlines sound really stupid when you first read them <333

Top 10 Most Amazing James Webb Space Telescope Discoveries - Details here

Hot New Planetary System Just Dropped.

We hope you like your planetary systems extra spicy. 🔥

A new system of seven sizzling planets has been discovered using data from our retired Kepler space telescope.

Named Kepler-385, it’s part of a new catalog of planet candidates and multi-planet systems discovered using Kepler.

The discovery helps illustrate that multi-planetary systems have more circular orbits around the host star than systems with only one or two planets.

Our Kepler mission is responsible for the discovery of the most known exoplanets to date. The space telescope’s observations ended in 2018, but its data continues to paint a more detailed picture of our galaxy today.

Here are a few more things to know about Kepler-385:

All seven planets are between the size of Earth and Neptune.

Its star is 10% larger and 5% hotter than our Sun.

This system is one of over 700 that Kepler’s data has revealed.

The planets’ orbits have been represented in sound.

Now that you’ve heard a little about this planetary system, get acquainted with more exoplanets and why we want to explore them.

We can't understand nature without understanding its range. That's apparent in exoplanet science and in our theories of planetary formation. Nature's outliers and oddballs put pressure on our models and motivate scientists to dig deeper. Gliese 367 b (or Tahay) is certainly an oddball. It's an Ultrashort Period (USP) planet that orbits its star in only 7.7 hours. There are almost 200 other USP planets in our 5,000+ catalog of exoplanets, so Gliese 367 b isn't unique in that regard. But it's an outlier in another way: it's also an ultra-dense planet—almost twice as dense as Earth. That means it has to be almost pure iron.
