When a star like our Sun evolves into a red giant, what happens to its planets? A new study explores this apocalyptic future.
Turbulent Beginnings for Future Planets?
Recent observations from ALMA are providing a new look at the presence — and absence — of turbulence in planet-forming disks.
New Discoveries from Old Spacecraft
The Voyager probes, launched more than 40 years ago, are still providing new insights.
An Explosive Merger … Maybe
Could a pair of faint signals correspond to the first collision we’ve detected of a black hole with a neutron star?
