Hubble Space Telescope

The Triangulum Galaxy, the third-largest member of the Local Group of galaxies, is shining with star formation in a new image from the Hubble Space Telescope.

The Hubble Space Telescope zooms in on a dense ball of millions of stars within a galaxy orbiting the Milky Way. Its ancient origins raise big questions about how galaxies form and grow.

A new multiwavelength 3D visualization of the iconic "Pillars of Creation" showcases the differences between Hubble and James Webb Space Telescope data.

The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

The Hubble Space Telescope's stunning image of the dusty 'train-wreck' galaxy NGC 4753 reveals what may be one of the greatest optical illusions in the nearby universe.

Astronomers celebrated the Hubble Space Telescope's 34th anniversary with this stunning image of the Little Dumbbell Nebula — a vast cloud of gas containing one of the hottest white dwarf stars ever found.

Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.

ESO 420-G013 is a face-on spiral galaxy with an almost perfectly round disk and an active black hole lighting up its starry guts.

The irregular dwarf galaxy UGC 8091 is likely a building block of ‘grand design’ galaxies like our Milky Way.

University of Chicago astronomer Wendy Freedman tells us how she's searching for an answer to the Hubble tension — a discrepancy between measurements of our universe's expansion that could threaten the dominant model of how the universe has grown since the Big Bang.
