Just a quick mention in case you missed the original announcement.

“Above a certain mass, the atoms inside large planets will begin to compress so severely that adding more mass will actually shrink your planet. This happens in our Solar System, explaining why Jupiter is three times Saturn’s mass, but only 20% physically larger. But many solar systems have planets made out of much lighter elements, without large, rocky cores inside.”

You might think that Jupiter is the largest planet in the Solar System because it’s the most massive, but that’s not quite right. If you kept adding mass to Saturn, it would get larger in size, but if you kept adding mass to Jupiter, it would shrink! For a given set of elements that your planet is made out of, there’s a maximum size it can reach, that’s somewhere in between the mass of Saturn and Jupiter in general. Our Solar System is on the dense side of things, meaning that we’ve discovered a large number of exoplanets out there that are approximately twice the physical size of Jupiter without becoming brown dwarfs or hydrogen-fusing stars. For worlds like WASP-17b, where we’ve measured both the radius and mass, we find that they’re only about half the mass of Jupiter, despite being double the size.

Come get the full scientific story, and some very informative and illustrative images with no more than 200 words, on today’s Mostly Mute Monday!

Marching for the right to be wrong: What it means to protest in the name of science. "The most obvious thing that our government can do, and our society along with it, is to help science to flourish in its own right, and accept what it has to teach us. Sometimes research tells us answers we don’t want to hear—that human activity is warming the planet, that we share a common ancestor with other living beings here on Earth, or that the universe is winding down toward its ultimate heat death. We need the courage to face up to the truth, whatever it turns out to be." https://www.theatlantic.com/science/archive/2017/04/marching-for-the-right-to-be-wrong/523842/

As NASA’s Cassini spacecraft moves toward its Grand Finale, it will conduct its final and closest flyby of Saturn’s moon Titan on April 22, 2017, passing over Titan’s surface at just 608 miles (979 kilometers), where instruments will conduct closeup observations of the hydrocarbon lakes near the moon’s north pole and use radar to look through its atmospheric haze and image surface detail. One of the most amazing sites in the Solar System.
