  APOD Search Results for "ngc 253"
NGC 253 is not only one of the brightest spiral galaxies visible, it is also one of the dustiest.
NGC 253 appears visually as one of the brightest spirals on the sky, and is easily visible in southern hemisphere with a good pair of binoculars.
NGC 253 is considered a "starburst" galaxy because of high star formation rates and dense dust clouds in its nucleus.

NGC Managers are also responsible for ensuring that employees under their supervision are familiar with NGC’s policies, rules and guiding principles.
NGC actively supports employees’ membership in professional bodies, which prescribe and regulate rules of conduct and ethical behaviour that members are expected to adhere to and advocate.
Some of the other rules that NGC enforces to ensure fair treatment and transparency include competitive bidding; sealed bids opened in the presence of all bidders; and uniformity, consistency and transparency in all communications with tenderers on any substantive aspects of their bids subsequent to their submission.

 NGC 3991/4/5   (Site not responding. Last check: 2007-11-06)
NGC 3995, at left (east), has the distinction of being the bluest galaxy in the Second Reference Catalog, as well as of being termed a supergiant compact galaxy by Vorontsov-Velyaminov (this kind of thing can happen if you define compactness with a surface-brightness rather than size criterion).
NGC 3991 is the shred-like string of star-forming regions at the northwest corner, and NGC 3994 is the spiral with an internal ring of star-forming region at the southern end of this little grouping.
NGC 3995 is also distinguished by having an extraordinarily small rotation velocity - if it is really a disk seen almost edge-on, it has only one tenth of our galaxy's rotation speed.

 Gemini Observatory   (Site not responding. Last check: 2007-11-06)
In the image, the face-on spiral galaxy NGC 6946 is ablaze with colorful galactic fireworks fueled by the births and deaths of multitudes of brilliant, massive stars.
Yet, it is the ubiquitous occurrence of starbirth throughout NGC 6946 and not its supernovae that lend this galaxy its blazingly colorful appearance.
NGC 6946 lies between 10 and 20 million light-years away on the border between the constellations of Cepheus and Cygnus, and was discovered by Sir William Herschel (1738-1822) on September 9, 1798.

 Atoms for Peace Galaxy (NGC 7252)
These unusual, young-looking globular clusters are the most obvious fruits of the suspected galaxy merger, originating in the infall of gas and subsequent burst of star formation that the merger triggered.
The globular clusters found in NGC 7252 are thought to resemble the progenitors of similar clusters that orbit the Milky Way Galaxy.
That this structure is a remnant of the collision between two galaxies is also supported by the fact that the mini-spiral is rotating in a direction opposite to the rest of the galaxy.

 NGC 5866 / Messier 102 ?
NGC 5866 is a beautiful lenticular galaxy of visual magnitude 10.0 or 9.6 (the first value from Sky Catalogue 2000.0, the latter is an estimate by Don Machholz).
NGC 5866 was probably first seen by Pierre Méchain in March 1781, or by Charles Messier shortly after that time.
There is evidence that Charles Messier has probably observed NGC 5866 when measuring this position, as it is almost exactly 5 degrees preceding (west) of the actual position of the object, very probably a data reduction error of some kind.

NGC 1427A, which is located some 62 million light-years away from Earth in the direction of the constellation Fornax, shows numerous hot, blue stars in this newly released image obtained by the Hubble Space Telescope.
When the gas within NGC 1427A collides with the Fornax gas, it is compressed to the point that it starts to collapse under its own gravity.
To the upper left of NGC 1427A is a background galaxy that happens to lie near Hubble's line of sight but is some 25 times further away.

At a distance of 10 million light years, NGC 2403 is an Sc type galaxy, which has open spiral arms and a small nucleus.

Detailed observations of NGC 1275 indicate that the dusty material belongs to a spiral system seen nearly edge-on in the foreground.
NGC 1275 is about 235 million light-years away in the constellation Perseus.
Although similar in shape to the old globular clusters in the Milky Way galaxy, NGC 1275's clusters are much younger and contain 100,000 to a million stars each.

Unlike the Sun, many stars are found in brilliant clusters such as NGC 3293 where they spend their lives.
At birth, which should have been at much the same time for all the stars in NGC 3293, the most massive stars are hot and very luminous and therefore appear as the brightest blue stars.
The bright orange star in NGC 3293 is the member of the cluster which has aged fastest.

 NGC 4571   (Site not responding. Last check: 2007-11-06)
NGC 4571 was one of the discoveries of William Herschel who listed it as H III.602.
It was proposed as possible candidate for M91 by John Herschel in his General Catalogue (GC), and consequently in Dreyer's NGC; we now know that M91 is very probably NGC 4548 (H II.120).
NGC 4571 came into discussion in summer 1994 when a group of astronomers at the Canada France Hawaii Telescope (CFHT) used observations of 3 Cepheids in this galaxy for a determination of the Hubble constant.

 NGC 7331, Spiral Galaxy, and Galaxy Group
NGC 7331 is the brightest galaxy in Pegasus.
This, along with evidence of a very faint filament of material stretching between Stephan's Quintet and NGC 7331, argues for a past gravitational interaction.
NGC 7320, the largest member of the Quintet, lies in the foreground of its more distant members, and is the most likely candidate for an ancient association with NGC 7331.

Its asymmetry (with what look like a leading and trailing or upstream and downstream edge) rated it an appearance in the Arp Atlas, both individually (number 25) and as a wide pair with the elliptical galaxy NGC 2300 (number 114).
Concomitant with the high star formation rate inferred from H-alpha emission, NGC 2276 has had several observed supernovae throughout this century - most of them along the prominent western rim of star-forming regions.
The NGC 2276/2300 pair (or group, with some other faint galaxies) achieved notoriety with the detection by Mulchaey et al.

We have calculated the position of NGC 6397’s disk passage in a polar coordinate system with the origin at the Galactic center as shown in Figure 1.
We submit that NGC 6397 may have had the opportunity to trigger the formation of NGC 6231, and Wallin et al.
To determine if this case is really winnable, the large uncertainties in the locations of NGC 6397 and NGC 6231 at the time of the crime need to be better constrained.
