A decade of observations by NASA’s Hubble Space Telescope has produced the sharpest and most detailed images of the Andromeda galaxy. Zoom in and explore.

The Andromeda galaxy is the galaxy next door, a very faint, fuzzy thing in the night sky, larger than a full moon. Textbooks ...

The Andromeda galaxy, our cosmic neighbor, is far more turbulent than previously thought. A new survey by the Hubble Space Telescope has mapped the chaotic history of Andromeda’s dwarf galaxy ...

Astronomers deployed the Hubble Space Telescope over the course of a decade to conduct 600 separate observations to produce an extraordinary mosaic of the great spiral galaxy. Astronomer John S.

In the sprawling Hydra constellation, 137 million light-years away, lies NGC 3285B—a dazzling spiral galaxy recently ...

How did a Cepheid variable star help Edwin Hubble prove the Andromeda Nebula was a galaxy? Roger Brady San Quentin, California Cepheids are rare variable stars with periods ranging from about 1 to ...

Hubble had been in space for less than two years when its Goddard High Resolution Spectrograph detected traces of boron in a not-too-distant star. At an estimated age of 14.5 billion years, the ...

However, new research leveraging over a decade of data from the NASA/ESA Hubble Space Telescope, combined with observations from the Gaia space telescope, is challenging this long-held certainty.

Named after the agency’s first chief astronomer, the high-tech observatory is expected to launch in 2027 and will feature a field of view 100 times larger than that of the Hubble Space Telescope.
