Tell me the velocity of a star without telling me its velocity
Stars like hiding their ages! In today’s paper, the authors inferred velocities of thousands of stars, which will help to determine their ages!
Herald of the Change: A microlensing Jupiter-analogue spotted in K2 data portends Roman’s yield of new planets
Astronomers have just found Jupiter’s twin in a distant solar system. Their discovery technique may surprise you, and might just be the most important method for discovering Earth-like exoplanets in the next decade…

Make it or Brake it: Supporting Weakened Magnetic Braking with Asteroseismology
Do stars really spin down? Authors of today’s paper find out if what we’re seeing is real or a trick of the light.
Got ‘Em! An Eccentric, Long-Period Giant Sheds Light on Planet Migration
Today’s authors yelled, “Got ’em!” when they discovered a failed hot Jupiter that aids in our understanding of giant planet migration.
That’s no planet! It’s one to five moons.
Most planets in our solar system have multiple moons, from Mars’ 2 to Saturn’s ~82. Today’s paper explores the stability and detectability of multi-”exomoon” systems orbiting planets beyond our solar system.
