Nebula- NGC 2070 |
|
Info |
NGC 2070 is a huge complex of
swirling hydrogen gas around 1000L.y. in diameter located in the large
Megallanic Cloud.. (a satelite galaxy to the Milky Way approximately
169,000 L.y away). At the centre of the nebula is a cluster of super giant
stars called R136, the light from which illuminates the surrounding
nebula. This glowing cloud of gas and dust is
one of the most dynamic star-forming regions in our local group of
galaxies. It harbours some of the most massive stars in the universe, up to
100 times more massive than our own Sun, and is the only nebula outside
our galaxy visible to the naked eye. |
