Explanation: <\/b>
\nHow did a hamster wheel get into space? The Hamster Wheel Nebula (Longmore 8) was
\ndiscovered by Andrew Longmore<\/a>
\nin 1976 as a part of a larger survey of the southern sky. This survey employed several improvements in
\nphotographic technology<\/a>,
\nincluding the use of
\nhighly sensitive film<\/a>,
\nto capture deeper and fainter objects on
\nplates<\/a>
\nthat were examined
\nby eye<\/a>
\nand catalogued.
\nThe featured image<\/a>,
\ntaken at Observatorio El Sauce<\/a>
\nin Chile, depicts an intricate wheel structure of glowing hydrogen that was thrown out into space by a
\ndying star<\/a>
\nand ionized<\/a>
\nby the leftover
\nwhite dwarf<\/a>.
\nThis structure was barely visible on the original plate, emphasizing the power of modern
\ntelescopes and cameras. Two opposing clumps of red hydrogen gas encased in
\nthe blue veil of ionized oxygen<\/a>
\nhint at the presence of a
\ncompanion<\/a>
\nto the bright white dwarf at the wheel\u2019s center!<\/p>\n
