A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...

A lucky alignment of galaxies allowed researchers to identify the most powerful and distant "space laser" ever found.

It was based on observations from the James Webb Space Telescope, Gemini North Telescope, and NASA/ESA Hubble Space Telescope ...

It's 99 percent dark matter, a new study explains.

When you gaze up at the night sky, you’re looking back in time. Light from the stars takes years, sometimes millennia, to ...

Astrophysicists at the University of Waterloo using the James Webb Space Telescope have spotted the most distant jellyfish galaxy ever observed.

Deep space has just delivered a cosmic riddle that refuses to fit any familiar category. Astronomers using some of the most powerful observatories ever built have identified a vast, dim structure that ...

Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams ...

New observations from the NASA/ESA/CSA James Webb Space Telescope reveal a galaxy with sweeping gaseous ‘tentacles’ in a galaxy cluster at redshift of 1.156, meaning we’re seeing it as it was ...

The Central Molecular Zone, spanning 700 light-years across the heart of the galaxy, contains a majority of the dense gas in the Milky Way. While analyzing this region with the Atacama Large ...
