Astronomers Observe Starburst Galaxy NGC 4449
Astronomers using the Gemini North telescope at the International Gemini Observatory have imaged NGC 4449, a prime example of starburst activity caused by ongoing mergers with nearby dwarf galaxies. This image, taken by the Gemini North telescope, one half of the International Gemini Observatory, shows the starburst galaxy NGC 4449. The image is being released
Physicists Observe ‘Unobservable’ Quantum Phase Transition
In 2019, Noel and her colleagues began collaborating with two theorists who had come up with an easier way of doing the experiment. They had worked out a way of setting aside one qubit that, like a canary in a coal mine, could serve as a bellwether for the state of the entire chain. The
Biologists Observe Highly Unusual Reproductive Behavior in Endangered Freshwater Mussels
In spring, female thick-shelled river mussels (Unio crassus) were seen moving to the water’s edge and anchoring into the riverbed, with their back ends raised above the waterline; then they squirted out regular water jets, which landed in the water up to a meter away; squirting cycles lasted 3-6 hours. The jets disturb the river
Scientists observe mysterious death of a star emitting six rings
Astrophysicists studying in unprecedented detail a red giant star named V Hydrae -- abbreviated as V Hya -- have witnessed the star's mysterious death throes. Researchers from UCLA and NASA's Jet Propulsion Laboratory discovered that the carbon-rich star has expelled six slowly expanding molecular rings and an hourglass-shaped structure ejecting matter out into space at…
