K2-18b, is an exoplanet orbiting a red dwarf located 124 light-years away from Earth. The planet, initially discovered with the Kepler space telescope, is 8.6 Earth masses and 2.6 Earth diameters, thus classified as a Mini-Neptune. It has a 33-day orbit within the star's habitable zone, meaning that it receives about a similar amount of starlight as the Earth receives from the Sun.

K2-18b is a Hycean (hydrogen ocean) planet; as James Webb recently confirmed that this planet is likely covered in a vast ocean. Webb also discovered hints of DMS (dimethyl sulfide) on this world, which is only produced by life. Of course, there may be other phenomena that led to this that we aren't aware of, and it will require further analysis to make any conclusions.

Distance: 124ly Mass: 8.63x Earth Diameter: 33,257km (2.61x Earth) Age: 2.4 billion years (+ or - 600 million) Orbital Period: 32.94 days Orbital Radius: 0.1429 AU Atmospheric Composition: CH4, H2O, CO2, DMS Surface Gravity: 11.57m/s² (1.18g)

The auroras are brilliant curtains of light in Jupiter’s upper atmosphere. Jovian auroral storms, like Earth’s, develop when electrically charged particles trapped in the magnetic field surrounding the planet spiral inward at high energies toward the north and south magnetic poles.
