Europe’s state-of-the-art Very Large Survey Telescope – VST – in Paranal, Chile, has captured some of the most detailed images ever taken of a spiral galaxy. The Silver Coin Galaxy, known to scientists as NGC 253, gleams about 11.5 million light years away in the southern constellation of Sculptor.
One light year is the distance that light travels in 365 Earth days, about 9.46 trillion kilometres or 5.87 trillion miles. NGC 253 is labelled a “starbust” galaxy because it is a stellar nursery where super-hot young stars have ignited, forming what look like bright clumps dotting its spiral.
The radiation streaming from these giant blue-white babies makes the surrounding hydrogen gas clouds glow green in the images captured by the telescope, the European Southern Observatory – ESO – said in a statement. Read the full article »»»»
