Astronomers from the Queen's University in Kingston, Canada and elsewhere, have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a mysterious source known as VLA 1623 West. Results of the study, published ...
Using NASA's Wide-field Infrared Survey Explorer (WISE), astronomers from South Korea and China have detected a mid-infrared flare in an active spiral galaxy known as NGC 3786. The researchers assume that this peculiar flare ...
When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while—less ...
