NGC 2060 is a star cluster within the

Tarantula Nebula The Tarantula Nebula (also known as 30 Doradus) is a large H II region in the Large Magellanic Cloud (LMC), forming its south-east corner (from Earth's perspective). Discovery The Tarantula Nebula was observed by Nicolas-Louis de Lacaille durin ...

R136 R136 (formerly known as RMC 136 from the Radcliffe Observatory Magellanic Clouds catalogue) is the central concentration of stars in the NGC 2070 star cluster, which lies at the centre of the Tarantula Nebula in the Large Magellanic Cloud. Wh ...

. It was discovered by John Herschel in 1836. It is a loose cluster approximately 10 million years old, within one of the Tarantula Nebula's superbubbles formed by the combined stellar winds of the cluster or by old supernovae. NGC 2060 is often used synonymously for the

supernova remnant A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar mat ...

N157B (30 Doradus B) which is a larger area of faint nebulosity and strong radio emission. The supernova occurred approximately 5000 years ago from our point of view. In 1998 a pulsar (named PSR J0537-6910) was discovered with the very fast rotation period of 16 milliseconds and the same approximate age as the supernova remnant.

VFTS 102 VFTS 102 is a star located in the Tarantula nebula, a star forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The peculiarity of this star is its projected equatorial velocity of ~ (about ), making it th ...

O-type main-sequence star An O-type main-sequence star (O V) is a main-sequence (core hydrogen-burning) star of spectral type O and luminosity class V. These stars have between 15 and 90 times the mass of the Sun and surface temperatures between 30,000 and 50,000 K. T ...

found with NGC 2060, which is proposed to be a companion of the pulsar ejected at the time of the supernova explosion. NGC 2060 has been identified as one of the few locations for OVz stars, stars with unusually strong He_II 468.6 nm absorption indicative of weak stellar winds and relatively low luminosity for the class. These stars are found in extremely young clusters and are thought to be a very early stage in the evolution of the most massive stars. They are also found in the much more massive NGC 2070 cluster nearby in the Tarantula Nebula.
