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 ...

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark universe ... astronomers would conduct galaxy surveys by taking ...

Scientists use 3D galaxy maps to uncover hidden details about dark matter and the universe’s large-scale structure.

A minority view ... one star system (or galaxy) among myriad others. This was the birth of our modern universe of galaxies, so poetically celebrated in Seeing in the Dark. Today, astronomers ...

The Hubble Space Telescope has provided the most detailed survey of the Andromeda galaxy, revealing new clues about its ...

This puzzling result makes sense if one assumes that the boundary stars are feeling the gravitational effects of an unseen mass—dark matter—in a halo around the galaxy. Dark matter could also ...

Hubble has previously imaged the same nebula, with an image released in 2023 and another shared in 2020. You might also recognize the name of this nebula as it was made world famous when the James ...

The Milky Way is our home galaxy ... face-on view of it. Instead, we see it as an arc of light across the night sky. It's one of the most beautiful sights in nature, but it requires a dark sky ...

Dark stars can be incredibly huge, stretching for thousands of light-years, while still having relatively low density. This would match observations of galaxy cores, which makes this an intriguing ...

Pinwheel Galaxy. Its swirling spiral arms display a high rate of star formation and host six detected supernovae. This image was captured with the Department of Energy-fabricated Dark Energy ...
