M7.3 earthquake (magnitude may change as more data becomes available) in the Tonga region.

The region near todays M7.3 earthquake is incrediblely active due to the high rates of convergence between the Australian and Pacific Plates. Since 1900, 40 M7.5+ earthquakes have been recorded, as well as at least 3 M8+ events.

@_astronoMay 51 Pegasi b is the planet that orbits its star in only 4 days right? That's insanely fast!
And that's four Earth days right?

@_astronoMay I don't think a "Hot Jupiter" could form so close to its host star. It must have formed much further out and is slowly migrating inward. I'd like to see if 51 Pegasi b, for example, is on that slow spiral and will one day crash into the star Pegasi itself. Or get ripped apart when it gets a little bit closer than it is now. A four day orbital period is ridiculous.

@_astronoMay - Is there a tool with which we can determine if an exoplanet has a magnetic field or not?
A method to estimate the age of the star might be useful too.

@_astronoMay - we need to get NASA to create an account for @JWST asap!
