Making stars when the universe was half its age

The universe is about 13.8 billion years old, and its stars are arguably its most momentous handiwork. Astronomers studying the intricacies of star formation across cosmic time are trying to understand whether stars and the ...

Dark Energy Survey completes six-year mission

After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey (DES) will finish taking data tomorrow, on Jan. 9.

Hubble goes deep

This image from the Hubble Deep UV (HDUV) Legacy Survey encompasses 12,000 star-forming galaxies in a part of the constellation Fornax known as the GOODS-South field. With the addition of ultraviolet light imagery, astronomers ...

Gravitationally lensed quasars

The path of light is bent by mass, an effect predicted by Einstein's theory of gravity, and when a massive galaxy or cluster lies along our line-of-sight to a more distant galaxy its matter will act as a lens to image the ...

Image: Hubble finds smiling face in a hunt for newborn stars

This image, taken with the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), shows a patch of space filled with galaxies of all shapes, colors and sizes, many of which belong to the galaxy cluster SDSS J0952+3434.

VIDEO: 5,000 robots merge to map the universe in 3-D

How do you create the largest 3-D map of the universe? It's as easy as teaching 5,000 robots how to "dance." DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by ...
