Astronomers have detected fast-repeating radio bursts from a distant "dead" galaxy that should not contain the energy to produce these types of signals.

Scintillation measurements show that FRB 20221022A originated from the highly magnetized region around a neutron star, challenging existing models of conditions there ...

A hundred years ago, astronomer Edwin Hubble dramatically expanded the size of the known universe. At a meeting of the American Astronomical Society ...

The starburst galaxy NGC 1569 glows brilliantly, illuminated by the light of millions of newly formed young stars. This image of LH63, cloaked in red, was captured by the Hubble Space Telescope and ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

An extremely slow pulsar has made scientists “slow down” their assumptions about other pulsars. The pace could be caused by a ...

Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon ...

An alien signal, reverberating in the vacuum of space, that was picked up on Earth has been confirmed to be coming from an ...

Astronomers have traced a mysterious fast radio burst to an unexpected place — an ancient, massive galaxy far removed from ...

An object we thought belonged to the most common category of planet in the galaxy has turned out to be something we've never ...

The Hubble Space Telescope completes a high-resolution portrait of our galaxy's gorgeous neighbor, which will help scientists better understand our Milky Way.

Around 2015, astronomers took on the painstaking task of stitching together Hubble Space Telescope images of this galaxy, but that effort had focused on the galaxy's northern half. Still, however, the ...
