EPSC-DPS 2019: Welcome

This week we’re at the joint EPSC-DPS 2019 planetary science meeting in Geneva, Switzerland. Follow along for some of the latest updates!

Boyajian's star

We thought that the bizarre dimming events of Boyajian’s star made it a one-of-a-kind source. But what if it isn’t?

M31 and satellites

Constraining Collisions of Dark Matter

A new study sheds some light on mysterious dark matter using faint satellite galaxies around the Milky Way.


Radio Pulsars: How Slow Do They Go?

Pulsars aren’t always speedy spinners! Astrobites reports on the slowest-spinning radio pulsar yet discovered.

silicate grains

Laboratory astrophysics experiments are giving us an up-close look at how complex molecules can form on the surfaces of dust grains.

planet formation

Astrobites reports on how magnetic fields might be to blame for these giant planets’ lazy rotation rates.

Astrobites reports on how the surface of the Moon might hold the key to understanding early activity of the Sun.


A New Site for the s-Process?

Astrobites reports on the possibility of a new site for the formation of s-process elements: in rapidly rotating, massive, metal-poor stars.

Saturn's rings from Cassini

Saturn’s iconic icy rings can teach us a lot. Can they tell us anything about past impacts on this distant gas giant?
