Throwing Icebergs at White Dwarfs
Where do the metals come from that pollute the atmospheres of many white dwarfs? Distant planet-size and icy objects could be partly at fault.

Astrobites discusses how we can explore the cloudiness of the exoplanets we observe.
What happened when G2 encountered Sgr A*, the supermassive black hole at the center of our galaxy, in 2014? Not much, but maybe that’s not surprising.
New Hubble images of two ultra-diffuse galaxies have revealed an enormous number of globular clusters. Why do these dim galaxies host so many?
Distant quasars can appear to twinkle when material lies between them and us. A new study blames nearby hot stars for some of the extreme variability of quasars.

Hidden black holes have been discovered lurking in the centers of nearby low-mass galaxies.
Small, speeding clouds discovered at the center of our galaxy may have been formed by plunging black holes.
Hot Jupiters are predicted to spiral ever closer to their hosts until they meet their eventual demise. Are we watching this happen with WASP-12b?
Astrobites reports on the latest voice in the debate of whether there is a Planet Nine.
We’ve never spotted a circumplanetary disk before — but thanks to new simulations, we now have a better idea of what to look for.
