A Pebbly Barrier to Planet Formation
While a planet is forming, its passage through the protoplanetary disk can prevent pebbles from migrating inwards and accreting onto the planet.
Diagnosing the amnesia of Exoplanetary Systems
How can size ordering of multiplanet systems be used to quantify the information content that these systems may retain about their formation history? Think information entropy.
Planet Frequencies in the Galactic Bulge
Microlensing could hold the key to studying planet formation in incredibly crowded regions of the galaxy, and today’s paper shows us how.
First detection of an equatorial jet on Venus
Slowly-rotating Venus has some seriously speedy clouds. Using near-infrared images from Japan’s first Venus orbiter, Horinouchi and collaborators study the atmospheric dynamics of our strange sister planet.
Somewhere in the Stratosphere
If you thought the weather on Earth was wild, think again: today we’re discussing the climate of WASP-121b.
What are Mars’ moons made of?
The tiny Martian moons Phobos and Deimos were initially thought to be captured asteroids. Now, it looks like they might be remnants of a collision 4.3 billion years ago. Can simulations help us figure out what they’re made of?
