NGC 602 is a young, bright open cluster of stars located in the Small Magellanic Cloud (SMC), a satellite galaxy to the Milky Way. Radiation and shock waves from the stars have pushed away much of the lighter surrounding gas and dust that compose the nebula known as N90, and this in turn has triggered new star formation in the ridges (or "elephant trunks") of the nebula.
Cat's Eye Nebula ...Cosmos is a Greek word for the order of the universe. It is, in a way, the opposite of Chaos. It implies the deep interconnectedness of all things. It conveys awe for the intricate and subtle way in which the universe is put together.
nsx: ハッブル宇宙望遠鏡から撮った地球の写真とのこと。今までの地球の写真のイメージとはずいぶんが違って雲が立体的にとらえられてる。撮り方にもよるのかな。 http://pic.twitter.com/8QHyCn9zuS— kita (@kitakazuo) March 1, 2016
NGC 7635: Bubble Nebula, an H II region emission nebula in Cassiopeia. The 'bubble' is created by the stellar wind from a massive hot, 8.7 mag. young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble itself being excited by the hot central star, causing it to glow. The star SAO 20575 is thought to have a mass of 10-40 Solar masses Wikipedia
