NASA has shared photograph featuring three different galaxies. And , the space agency has also explained how these galaxies don’t let any “labels define them”. Confused? Let’s unpack. On June 13, NASA posted a photograph of three galaxies — one right center other two spotted on right and bottom of . The photo was captured by the wide-field camera 3 of NASA’s Hubble telescope. Now, let’s understand what makes these galaxies unique. In its Instagram post, the agency said that the galaxy pictured middle was “difficult to classify” reasons are very interesting.
While sometimes classified as a , our own , also sometimes classified as a lenticular galaxy,” the agency says. “Lenticular galaxies are a galaxy type that sits between spiral and elliptical varieties.” Now, it more complex, right?
But here’s way of it. NASA says the galaxies grow we do. “While the spiral arms of this galaxy are distinguishable, clearly defined. Pictured here, the tip arm appears to be diffused,” it says.
These galaxies are in good company 💫

Galaxies static, and their morphologies (and therefore their classifications) vary throughout their lifetimes, says NASA separate note published on its website.
“Spiral galaxies are thought to evolve into elliptical. happen by merging with , causing them to lose their distinctive spiral structure,” NASA says further in its Instagram post, explaining how even the galaxies change their composition with time.
The agency says that the NGC 4680 middle is flanked by two other galaxies as we explained above. Interestingly, NGC 4680 enjoyed a wave of attention in 1997, playing host to a supernova explosion SN 1997bp, says NASA.
NASA shared picture on Twitter and a user wondered if the space agency ever flirted with of sending its astronauts galaxies.
Another user, though, explained why nearly impossible for NASA to undertake any such mission.
The Hubble telescope, which captured , was launched in 1990 as a collaboration project between NASA European Space Agency. The telescope has an unobstructed view of the universe.
