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 ...

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 highly inclined barred spiral M108 in Ursa Major is sometimes called the Surfboard Galaxy. It's not to be missed.

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 us how the first galaxies were born and helps us understand how the ...

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 ...

In a dense galaxy cluster, NGC 4858 shows how cosmic winds strip gas, spark new stars, and shape stunning jellyfish-like features.

"The Sculptor Galaxy is in a sweet spot. It is close enough that we can resolve its internal structure, but at the same time big enough that we can still see it as a whole system." ...

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 ...
