The middle of our galaxy makes for a stunning desktop screen background – but what , exactly , is blend in on in this image ?
This composite image is an golden oldie , but it ’s a goodie . It was released back in 2009 in celebration of the International Year of Astronomy . At the time , it was the most elaborated and most colorful effigy of the center of our galaxy ever assembled , a combining of near - infrared , infrared and tenner - ray images acquired by the Hubble Space Telescope , Spitzer Space Telescope and Chandra ecstasy - irradiation Observatory , severally . you may explore in great detail inthe high-pitched - res version featured here .
I fetch it to your attention now because , for as many times as I ’ve see this image , I ’ve never seen it annotated . There ’s obviously a sight going on in this look-alike , and beautiful though it may be , it would be helpful to know where one might get , say , the black yap that it presumably contains .
The above image , which I of late happen upon in a backdate NASA APOD post , serves as a helpful pathfinder to the virtuoso fields , star clusters , gaseous filament , supernova remnants and the industrious surroundings of the black-market hole thought to exist at the pith of the Milky Way ( that would be the location label “ Sagittarius A , ” where a supermassive dark pickle four - million times as massive as the Sun reside ) .
