We know far more about that now than we did then.

You read the title right. Recently, some astronomers thought they had spotted an “exomoon,” a moon orbiting an exoplanet. There are, of course, bound to be some. But now Gizmodo introduces us to the concept of the moonmoon, a submoon orbiting a moon. One research team is taking on the possibility: The team’s short analysis […]
Astronomers: First possible exomoon is the size of Neptune, and orbiting a “Jupiter”
An MIT astronomer is 75% certain that an object previously suspected of being an Intro of exomoon (a moon orbiting an exoplanets) really is that: The first confirmed detection of an exomoon would mark a milestone in exploring planetary systems throughout the Galaxy. It would, among other things, allow scientists to test ideas of moon […]
Might we find evidence of past life on the Moon?
Well, not today. But at one time, the Moon was not completely separate from Earth. It really depends on how long ago life got started here whether some microbial life could have been trapped on the moon and survived a while. The sagas of the worm that survived the space shuttle blowup and the water bears in space should warn against too-hasty dismissal.
Moon formed from smashed moonlets?
From Hanneke Weitering at LiveScience: Earth’s moon may be the product of many small moonlets that merged after multiple objects as big as Mars collided with Earth, leaving disks of planetary debris orbiting the planet, a new study suggests. This idea that multiple impacts led to the moon’s birth challenges the most prevalent theory of […]
