Researchers compiled hundreds of astronomical observations into a high-definition image of a cosmic filament, part of the megastructure that undergirds the universe’s matter. The filament connects two galaxies that date back to when the universe was a youthful 2 billion years old (it is now about 13.77 billion years old). It showcases the way a […]
Hubble Hits the ‘Bullseye,’ a Galaxy With Record-Breaking 9 Rings
The Hubble Space Telescope just imaged a massive bullseye in space: LEDA 1313424, or the Bullseye Galaxy, which is about 2.5 times the size of the Milky Way. Despite the galaxy’s size, capturing this image proved no small feat. The Bullseye (affectionately) lies 567 million light-years from Earth, making it a rather distant object to […]
Mysterious Radio Bursts Traced to the Edge of an Ancient, Dying Galaxy
In February 2024, scientists on Earth detected a powerful radio blast from outer space. Seeking to discover where it had come from, they traced the brief flash of energy back to its extraterrestrial source—and discovered something unexpected. Scientists led by Northwestern University and McGill University have traced a fast radio burst (FRB) to the edges […]
