International team detected radio bubbles with South Africa’s MeerKAT telescope. A gigantic, balloon-like structure has been hiding in plain sight, right in the center of our own galaxy. An international team of astronomers, including Northwestern’s Farhad Yusef-Zadeh, discovered the structure, which is one of the largest ever observed in the Milky […]

(Image: © SpaceX) SpaceX is planning to launch the second installment of its Starlinkmegaconstellation on Monday (Nov. 11), and astronomers are waiting to see — well, precisely what they will see. When the company launched its […]

An ancient gas cloud discovered by a team led including recent Carnegie-Princeton fellow Eduardo Bañados and Carnegie’s Michael Rauch and Tom Cooper formed just 850 million years after the Big Bang. Its chemical composition reveals that the first generation of stars formed quickly and rapidly and enriched the universe with […]

Graphic shows the basic design of an X-ray free electron laser or XFEL, in which brilliant X-ray bursts strike crystallized samples, causing diffraction patterns that can be reassembled into detailed images. X-rays damage biomolecules, a problem that has plagued structure determination efforts for decades. But the X-ray bursts produced by […]
