Hubble spots irregular spiral galaxy NGC 5486

The irregular spiral galaxy NGC 5486 hangs against a background of dim, distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The tenuous disk of the galaxy is threaded through with pink wisps of star formation, ...

Milky Way found to be too big for its 'cosmological wall'

Is the Milky Way special, or, at least, is it in a special place in the universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows ...

Webb captures luminous, face-on spiral galaxy NGC 7469

Webb's picture of the month for December is dominated by NGC 7469, a luminous, face-on spiral galaxy approximately 90,000 light-years in diameter that lies roughly 220 million light-years from Earth in the constellation Pegasus.

Can JWST see galaxies made of primordial stars?

All stars are composed of mostly hydrogen and helium, but most stars also have measurable amounts of heavier elements, which astronomers lump into the category of "metals." Our sun has more metals than most stars because ...

Hubble inspects two galaxies connected by a luminous bridge

This image from the NASA/ESA Hubble Space Telescope shows two of the galaxies in the galactic triplet Arp 248—also known as Wild's Triplet—which lies around 200 million light-years from Earth in the constellation Virgo.

Astronomers find cosmic rays driving galaxy's winds

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have discovered an important new clue about how galaxies put the brakes on vigorous episodes of star formation. Their new study of ...
