A Deep Look at Distant Galaxies with ALMA
We’ve seen what the powerful ALMA observatory can do within our own galaxy — but what can it tell us about distant galaxies across our universe?
Casting Doubt on a Nearby Black Hole
Scientists recently announced the discovery of the nearest black hole to Earth — but there may be a different explanation for this stellar puzzle.
How Planets Can Save or Destroy Their Siblings
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?
To Separate Starspots from Planets
Starspots on M dwarfs could be mistaken for planets. How do we distinguish the two?
The Link Between Black Holes and Their Galaxies
The size of a supermassive black hole seems to track with the size of its host galaxy. But is this a statistical fluke, or is there a physical reason for the connection?
New Molecules from GOTHAM
What as-yet unidentified molecules lurk in the dark clouds of our nearby universe? Answering this requires observation, experiment, and theory — and GOTHAM is on the case.
