It’s not yet December, but NASA is already in a festive mood: the Webb and Hubble space telescopes recently imaged MACS0416, a pair of colliding galaxy clusters 4.3 billion light-years from Earth that is bedecked in sparkling lights.
We now know how far away some galaxies are in the iconic "deep field" image from NASA's James Webb Space Telescope. A Canadian instrument is revealing more about how the universe changed over time.
A look at the night sky at any time of year will reveal a faint band of light stretching across the sky our solar system's home, the Milky Way. How much do we really know about it?
A new photo from the Hubble Space Telescope captures a face-on view of the Spanish Dancer galaxy, formally known as NGC 1566, located in the Dorado constellation.
