The brightest cluster of stars in this picture was believed until recently to contain a single, uniquely massive object with the mass equivalent to 1000 suns, and was named as a star, 30 Doradus. Sophisticated image analysis techniques have been used to show that 30 Doradus is a very compact group of stars, many of which are massive, but not unimaginably so. The radiation from this star cluster is sufficient to excite a huge cloud of hydrogen gas in its vicinity so that it glows with its distinctive red colour. This picture is essentially a one minute exposure. A longer exposure would show that the curving tendrils of nebulosity are the brightest parts of the huge Tarantula nebula, one of the largest star-forming regions known anywhere.
