NGC 5253 is an irregular galaxy in the constellation Centaurus. It was discovered by William Herschel on 15 March 1787. [4][5] NGC 5253 is located within the M83 Subgroup of the Centaurus A/M83 Group, a relatively nearby galaxy group that includes the radio galaxy Centaurus A and the spiral galaxy M83 (the Southern Pinwheel Galaxy).

ngc 5253是位于半人马座的一个不規則星系。 此星系亦是已知在地球附近的 藍緻密矮星系 之一，距地球約一千一百萬光年。 它也被視為 半人馬座 A/M83星系團 的一員。

NGC 5253位于 半人马座 A/M83群的M83亚群内，这是一个相对邻近的星系群，包括 射电星系 半人马座A和 螺旋星系 M83 (南平轮星系)。 NGC 5253被认为是一个矮星爆发星系，同时也是一个蓝色致密星系。 超新星1972 E，这是最近从地球上可见的第二颗最亮的超新星 (在20世纪的峰值视界为8.5级，仅比SN 87 A暗)。 另一颗超新星SN 1895b也在该星系中出现。 该星系也记录了另一颗超新星SN 1895b. NGC 5352包含一个巨大的尘埃云，隐藏着超过100万颗恒星的星团，其中多 …

2015年3月18日 · More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered. The star cluster is buried within a supernebula in a dwarf galaxy known as NGC 5253, in the constellation Centaurus.

2024年6月24日 · The focus of this week’s Hubble Picture of the Week is the blue compact dwarf galaxy NGC 5253, located in the constellation Centaurus around 11 million light-years from Earth. This new image combines data taken with Hubble’s Advanced Camera for Surveys (ACS), using its Wide Field Channel, and with the older Wide Field and Planetary Camera 2 ...

2012年11月30日 · The NASA/ESA Hubble Space Telescope captured an impressive image of the irregular galaxy NGC 5253. NGC 5253 is one of the nearest of the known Blue Compact Dwarf (BCD) galaxies, and is located at a distance of about 12 million light-years from Earth in the southern constellation of Centaurus.

2020年5月27日 · The blue compact dwarf galaxy NGC 5253 hosts a very young central starburst. The center contains intense radio thermal emission from a massive ultracompact H II region (or supernebula) and two massive and very young super star clusters (SSCs), which are seen at optical and infrared wavelengths.

2024年6月24日 · This picture from the NASA/ESA Hubble Space Telescope depicts the starburst galaxy NGC 5253, observed by two of Hubble’s instruments over a span of ten years. At the bottom is a wide view of the galaxy, comprising data from Hubble’s Advanced Camera for Surveys (ACS) using the Wide Field Channel, and from the older Wide Field and Planetary ...

We report the discovery of a peculiar H I velocity field in the nearby amorphous dwarf starburst galaxy NGC 5253 which indicates that the bulk of the neutral atomic gas rotates about the galaxy's optical major axis. There is also weak evidence for a second H I dynamical component rotating about the optical minor axis.

2024年6月24日 · This Hubble Space Telescope image showcases NGC 5253, a starburst galaxy actively forming massive star clusters. Located 11 million light-years away, it serves as a critical site for studying stellar processes.
