Habitable exomoons, kind of reminds me of the Andorian home world.
NewScientist have posted a video simulation of the creation of habitable moons showing it is a lot harder to be produced in the real world. You can watch the video below:
It turns out hit and run accidents involving planets could possibly create moons able to hold on to an atmosphere.
Just how many planets are there in our galaxy?
A study from Princeton has revealed that Gaia could potentially discover up to 70,000 planets in the galaxy over 10 years. This would lead to scientists getting a much better understanding of the number and variety of planets in our galaxy.
So far only 1,900 planets have been discovered. The more we discover the better we understand how likely it might be for life, to be elsewhere in the universe, even if it is only microbial.
Although Gaia is only set for a 5 year mission (reminds me of Star Trek), it could potentially be extended to 10 years, as does happen with many space craft, rovers, and satellites that continue to operate well past there intended mission life.
A low-mass, low-density exoplanet has been discovered, whose yearly orbit varies enormously from one year to the next.
The planet was discovered using citizen scientists via the Planet Hunter program. It uses hundreds of thousands of people to look at images to spot things that computers can't. As other planets in a system affect each others orbits, it's usually only very slight. Jupiter and Mars distort Earths orbit by about a second each orbit. However this discovery of this new planet show that it's planetary neighbors cause an orbital distortion of around 10.5 hours.
