What Shapes the Edge of a Planetary System?
Astrobites reports on whether Jupiter-like exoplanets are responsible for defining the edges of multiple-planet systems.

A distinctive pulsar wind nebula shaped like an outstretched hand is seen in polarized X-rays for the first time.
In order to get its present-day orbit, Enceladus must have felt the need for speed in its recent past.
Joining a galaxy cluster can fundamentally change a galaxy’s properties. New research looks at how galaxy clusters affect star formation beyond the local universe.
Astrobites reports on how modeling molecular clouds can help us understand how these cosmic nurseries form stars.
Colliding sunspots can produce solar flares, but not all collisions are accompanied by these outbursts. New simulations explore what it takes to make a solar flare.
Galaxies seem to have less matter than we think they should, but new research suggests it’s not missing — just hiding in the form of hot circumgalactic gas.
A rare binary system containing hot stars with powerful winds makes dust when the stars approach each other every 13 years.
Astrobites reports on a way to use an unlucky star to learn about a pair of supermassive black holes.
Globular clusters help researchers disentangle the formation history of an unusually diffuse galaxy.
Galaxies in the early universe were mostly pure hydrogen. How, then, did one end up with so much metal just a billion years after the Big Bang?
If dark matter and normal matter could interact, it could ease the emerging tension between measurements of how smooth or clumpy the distribution of matter is in our universe.
