First 'exomoon' may have been found

[Notebook]

Astronomers have announced the possible discovery of the first known moon outside our Solar System.
This "exomoon" is not like any in our cosmic neighbourhood: it's the size of Neptune and orbits a planet the size of Jupiter - but with 10 times the mass.
The object was spotted in data from Nasa's Kepler spacecraft, and later observed using the Hubble telescope.
Astronomers David Kipping and Alex Teachey have published their results in Science Advances journal.
But they say that further observations are needed to understand the distant planetary system.

So that would essentially be an ice giant orbiting an almost-brown dwarf. Or superjupiter. Supiter? Whatever we call objects of that size.

It would certainly be expected that the first exomoon we discover would be something extraordinary large. Let's hope it can be confirmed.

A moon he size of Neptune...

And here we all thought Titan was large.

Kepler and Hubble. One hell of a team.

A gas giant moon? That'd be something new, for sure.

Every new planet or moon we are discovering outside makes our solar system look more unique and organized compared to others.
