Icy Insights from Comets and Planet-Forming Disks
Are comets pristine remnants of the formation of our solar system, or have they changed since then? New work compares the chemistry of comets and planet-forming systems to answer this question.
Black Holes with a Shared Background
New research suggests that triplet stars might be able to evolve into every observable type of stellar-mass black hole system.
Astrobites reports on how X-rays influenced the formation of the first massive black holes in the universe.
The Sun Left Home in a Hurry
By studying the orbits of rare outer solar system objects, astronomers have estimated how long it took for the Sun to leave its birth cluster.
Astrobites reports on the discovery of the faintest galaxy in the Andromeda system, Pegasus VII.
Recent research shows how fractal properties can help distinguish between grand-design and flocculent spiral galaxies.
When supernovae explode, they send a fast-moving shock wave into the interstellar medium, changing the local landscape significantly. A recent publication hones in on one supernova remnant to determine how fast it’s expanding and where it may have come from.
Standing on a Sub-Neptune
If you were standing on a sub-Neptune exoplanet, would you be standing on a rocky surface or in a magma ocean?
Astrobites reports on the consequences of shooting an asteroid with a spacecraft.
