We detect widespread [C II] 157.7 mu m emission from the inner 5 kpc of the active galaxy NGC 4258 with the SOFIA integral field spectrometer FIFI-LS. The emission is found to be associated with warm ...

In the nearby galaxy NGC 4258, the well-modeled orbital motion of H2O masers about its supermassive black hole provides the means to measure a precise geometric distance. As a result, NGC 4258 is one ...

Then, by comparing that distance to how fast the galaxy is moving away, they get the expansion rate for that part of the universe. This gives a value of around 73 kilometers per second per megaparsec.

That’s where a galaxy called NGC 4258 became important. NGC 4258 hosts water-rich clouds called megamasers.

Messier 106, also known as NGC 4258, is a stunning intermediate spiral galaxy located in the constellation Canes Venatici. The galaxy was first discovered by French astronomer Pierre Méchain in 1781.

The team used about one-third of Hubble's total galaxy sample, with the distance to a well-studied galaxy called NGC 4258 as a reference point. This was compared against the largest yet sample of ...

The new study covered roughly a third of Hubble's full galaxy sample, using the known distance to a galaxy called NGC 4258 as a reference point. Despite the smaller dataset, the team achieved ...

The black hole lies at the centre of the featured spiral galaxy NGC 4258, or Messier 106, which is around 23 million light-years from Earth in the constellation Canes Venatici.
