What it is : voluted galaxy UGC 10043
Where it is:150 million low-cal - years away in the constellation Serpens
UGC 10043 is one of the few spiral galaxies we see edge-on.
When it was shared : December 12 , 2024
Why it ’s so special : This image of a whorled galaxy taken by theHubble Space Telescopeis a portrayal more than two decades in the devising .
Like most full - color image of space objects , it ’s a composite plant of image get in unlike wavelengths of light . What place this image asunder , however , is that the data used to create it was pick up during observance sessions in 2000 and 2023 — 23 years apart . That ’s one vantage of having a space telescope in orbit for so long : Hubble was launched from the space shuttle Discovery on April 24 , 1990 , and its long service has enabled it to beguile a huge amount of data about every box of the cosmos .
But besides the prolonged method used to make it , it ’s also an strange image on its face . Spiral galaxies — which account for about 60 % of all galaxies in the universe of discourse , fit in to theEuropean Space Agency — are , by chance , typically see face - on when viewed from thesolar organisation . That ’s why turbinate galaxies are typically consort with vivid helical arms , which can only be seen from a face - on advantage . However , UGC 10043 is viewed edge - on , with its anchor ring ostensibly flattened into a line . This unique slant gives astronomers the chance to see how spiral galaxies are structured in 3D.

This range of a function of UGC 10043 unwrap obvious lanes of detritus , which would likely see like spiral arms if the galaxy was seen side - on . Here , they appear to block the collective glow of the stars that make up the galax itself . They also contain dark clouds , which are star - organise realm .
At the center of the image is a bulge of light — the Galax urceolata ’s bright pith . All galaxies have one , but UGC 10043 ’s is unco large . astronomer think it may be because UGC 10043 has collided with a dwarf galaxy nearby , leaving it with extra detritus and gas pedal that has fuel it to make raw stars . A hit could also excuse why the galaxy ’s phonograph record is slightly warped , bending up at one terminal and down at the other .
