It ’s always the same . Just when I ’m thinking that I could n’t be surprised by the Hubble Space Telescope any longer , it captures another figure of speech that entrust me in awe . Like this searchlight - like beams in blank . It ’s what I ’d reckon the door to heaven would look like if I think in such things .
Or maybe a deep quad lighthouse . But in world , this dramatic showing of light and dust is the Egg Nebula , about 3,000 light - year from Earth . It ’s a protoplanetary nebula , meaning that there are no planet form yet , just an mature star stimulate its own textile remains around it .
These constitution are quite unique in the sky because , accord to NASA , their “ short lifetime of preplanetary nebula mean there are relatively few of them in universe at any one time . ” It ’s the best persuasion we have got to date , after it was discovered less than 40 years ago . NASA say that many aspects of these formations are still a enigma to be solved by astronomers :
At the centre of this image , and hide in a thick cloud of dust , is the nebula ’s central star . While we ca n’t see the star directly , four searchlight beam of light coming from it shine out through the nebula . It is think that band - work holes in the thick-skulled cocoon of junk , carved by jets amount from the star topology , let the beams of lighter issue through the otherwise unintelligible cloud . The precise mechanism by which stellar jets produce these pickle is not know for sure , but one potential explanation is that a binary star organisation , rather than a exclusive star , be at the center of the nebula .
Those layers that seem to form a portal to another property are really layer of stuff ejected by the dying adept every hundred years . [ NASA Goddard ]
