In September 2015, two days after the detection of GW150914, an alert went out to 63 ground- and space-based observatories. This launched the very first hunt for an electromagnetic counterpart to a gravitational wave signal.
New observations have caught two galaxies in the process of forming peanut-shaped bulges like the one in the center of our own Milky Way.
These vibrant images of supernova remnants in the Large Magellanic Cloud were created to explore the galaxy’s interstellar medium.
The search for the hypothetical Planet Nine has led to the discovery of a collection of new — and puzzling — objects located in the outer reaches of our solar system.
A new study has examined the preferred home for tidal disruption events — the shredding of passing stars by a supermassive black hole.
A recent stellar arc discovered in the Large Magellanic Cloud’s outskirts might be a clue to this dwarf galaxy’s collisional past.
Can protoplanetary disks form and be maintained around low-mass stars in the harsh environment of a highly active, star-forming nebula?
What if there were a better way to analyze a comet’s tail, the dimming of the Sun’s surface, or the path of material in a bright solar eruption?
Check out this beautiful Hubble map of Jupiter’s surface — and get excited for the Juno mission’s arrival at Jupiter today!
What could be causing the spirals we observe in some protoplanetary disks? Planets might have nothing to do with it.
Observations from the ice kilometers under Antarctica may help us to understand the source of ultra-high-energy cosmic rays.
Could hypervelocity stars be accelerated by a massive black hole in the center of the Large Magellanic Cloud?
