We present long-slit observations in the optical and near-infrared of eight H ii regions in the spiral galaxy NGC 4258. Six of the observed regions are located in the south-east inner spiral arms, and ...

Explore the warped spiral galaxy NGC 3718 and its neighbor NGC 3729 — a dynamic duo of deep-sky oddities in the constellation ...

This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is ...

It lies a short distance away from M102 (NGC 5866), a smaller galaxy that is also, coincidentally, oriented almost exactly edge-on. NGC 5907 is relatively large and bright, shining at magnitude 11 ...

The galaxy sits in a sweet spot that allows astronomers to study it in ways that can't be applied to even our own Milky Way ...

NGC 4449 is a dwarf galaxy turned stellar powerhouse, dazzling astronomers with its explosive star-forming activity and rich ...

Using NASA's Chandra spacecraft and ESA's XMM-Newton satellite, astronomers have investigated the galaxy NGC 7793, searching for supernova remnants (SNRs). As a result, they discovered four new X ...

"We have discovered a galaxy that has been 'perfectly preserved' for billions of years, a true archaeological find that tells ...

The Sculptor galaxy is similar in many respects to our Milky Way. It is about the same size and mass, with a similar spiral ...

One of these edge-on marvels is NGC 5907 in Draco. It is an SA (s)c galaxy, sometimes called the Splinter Galaxy or the Knife Edge Galaxy. It lies a short distance away from M102 (NGC 5866), a ...

A light-year is 5.8 trillion miles. Sculptor — officially labeled NGC 253 — is considered a starburst galaxy, one heavy with stellar action.
