This cluster was discovered by French astronomer Nicolas-Louis de Lacaille in 1752. It is at the centre of the Tarantula Nebula and produces most of the energy that makes the latter's gas and dust visible. Its central condensation is the star cluster R136, one of the most energetic star clusters known. Among its stars are many of great dimension, including the second most massive star known, R136a1, at 215 and 6.16 million . ::figure[src="https://upload.wikimedia.org/wikipedia/commons/5/5c/Dorado_IAU.svg" caption="Sky map position of NGC 2070 (green square)"] ::
