How superwinds help drive galactic development

Galactic superwinds—large outflows of gas created by a combination of supernova explosions and stellar winds—are closely connected to a galaxy's earliest stages of development and evolution, including aspects like its ...

Webb reveals cosmic cliffs, glittering landscape of star birth

This landscape of "mountains" and "valleys" speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA's new James ...

Nature of fast radio bursts clarified

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a fast radio burst after all. The bursts may come from a highly ...

First clear view of a boiling cauldron where stars are born

University of Maryland researchers created the first high-resolution image of an expanding bubble of hot plasma and ionized gas where stars are born. Previous low-resolution images did not clearly show the bubble or reveal ...
