Astrobites reports on the first known white dwarf to have survived the partial explosion of a (failed) Type Ia supernova.
Asteroids from a Martian Mega Impact
Could a long-ago giant impact have flung pieces of Mars throughout our inner solar system? Numerical simulations and clues from the mineral olivine point us toward an answer.
Magnetic Fields Versus Gravity
What can dust polarization measurements tell us about the magnetic fields in the star-forming region W51?
Clues from Bent Jets
A new study explores how observations of enormous radio jets can reveal information about the environments that surround them.
