NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.

NGC 4013是一个 漩涡星系,在 大熊座。 哈勃空间望远镜 抓拍了这一个令人印象深刻的“边缘向前”的星系 NGC 4013，这幅最新的哈勃图像详尽地揭示出该星系的 星系盘 被长长的气体和尘埃云覆盖着。 NGC 4013 是一个 螺旋星系, 类似我们自己的银河系，位于大熊座方向距地球约5千5百万光年的地方。 如果从极点方向看去，其应该看看起来像旋转的焰火轮盘，但是 NGC 4013 碰巧从我们的观察点看来是“边缘向前的”。 即使在5千5百万光年远的地方，该星系也比 哈勃望远镜 的 …

NGC 4013 is a spiral galaxy, similar to our Milky Way, lying some 55 million light-years from Earth in the direction of the constellation Ursa Major. Viewed face-on, it would look like a nearly circular pinwheel, but NGC 4013 happens to be seen edge-on from our vantage point.

1987年7月30日 · H I radio synthesis observations reveal that the edge-on Sbc 4 galaxy NGC4013 has the largest regular H I warp so far observed. It extends to a large height above the plane of the galaxy, and...

2017年7月11日 · ngc4013は典型的な渦状銀河を真横から見た単独のエッジオン銀河として知られていました。 しかし2006年の観測で銀河本体の北西に8万光年以上の大きさに広がるリング構造が発見されました。

2023年4月17日 · An amazing "edge-on" view of a spiral galaxy 55 million light years from Earth has been captured by the Hubble Space Telescope. The image reveals in great detail huge clouds of dust and gas extending along and above the galaxy's main disk. Photo credit: NASA and the Hubble Heritage Team (STSci/AURA)

1999年12月15日 · In this Hubble image, NGC 4013 is seen edge-on, from our vantage point. Because the galaxy is larger than Hubble's field of view, the image shows only a little more than half the object, but with unprecedented detail. Dark clouds of interstellar dust stand out, since they absorb the light of background stars.

2015年9月11日 · ngc4013 是大熊座的一个晚型的侧向旋涡星系，距离地球大约 5500 万光年，通常被认为是像银河系一样的旋涡星系。 然而它在很多方面存在着与银河系截然不同的特征： NGC4013 的气体盘翘曲是迄今观测到最大之一；壮观的环状恒星流；箱型结构恒星外晕；高质量 ...

1999年1月7日 · Abstract: The nucleus of the box-shaped galaxy NGC4013 has been observed with the IRAM interferometer in the J=1-0 and J=2-1 lines of 12CO. Our maps show the existence of a fast--rotating(130 km/s) molecular gas disk of radius r=110pc. Several arguments support the existence of a bar potential in NGC4013.

2011年7月4日 · NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" HI warp and its "giant" tidal stream. Previous work on this unusual object shows that it cannot be fitted satisfactorily by a canonical thin+thick disk structure.
