NGC 3254 is a spiral galaxy in the constellation Leo Minor. It was discovered on March 13, 1785, by the astronomer William Herschel. [4] It is a member of the NGC 3254 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [5]

2021年6月18日 · This image shows the spiral galaxy NGC 3254, observed using Hubble's Wide Field Camera 3 (WFC3). WFC3 has the capacity to observe ultraviolet, visible, and near-infrared light. The image is a composite of observations taken in the visible and infrared.

2021年6月14日 · In this image, NGC 3254 looks like a typical spiral galaxy, viewed side-on. However, NGC 3254 has a fascinating secret that it is hiding in plain sight — it is a Seyfert galaxy, meaning that it has an extraordinarily active core, known as an active galactic nucleus, which releases as much energy as the rest of the galaxy put together.

NGC 3254 is a Seyfert 2 Galaxy located in the constellation of Leo Minor in the northern hemisphere. NGC 3254's distance from Earth is 94,500,548.87 light years. NGC 3254 is called NGC 3254 in the New General Catalogue (NGC).

2022年4月8日 · NGC 3254 is listed as a Seyfert galaxy (type Sy 2) because of its unusually bright nucleus, which puts out as much light as the entire remainder of the galaxy, and is far brighter in ultraviolet wavelengths than in the visual images shown here (though the HST image is actually a composite of visual and infrared images, which accounts for some ...

2021年6月14日 · This Hubble image shows NGC 3254, a spiral galaxy located some 118 million light-years away in the constellation of Leo Minor. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).

NGC 3254 is a Spiral Galaxy in the Leo Minor constellation. NGC 3254 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 11.6, NGC 3254 is visible with the help of a telescope having an aperture of 8 inches (200mm) or more.

ngc 3254是位于小狮座的一个星系。它的赤经为 1029.3，赤纬为 29° 30′，大小 5.1′。

This object is a Seyfert galaxy located 120 million light years away in the constellation of Leo Minor at a declination of +29 degrees. It is a magnitude 11.6 galaxy which spans 5 arc-minutes in our apparent view. This corresponds to a large diameter of 160,000 light years. We are viewing this galaxy about 15 degrees from edge-on.
