NASA Shares Fascinating View of Three Galaxies And Explains Why they’re Unique:

NASA has shared a desirable photograph featuring three different galaxies. And thereupon, 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 within the center and therefore the other two spotted on the acute right and bottom of the image . 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 within the middle was “difficult to classify” and therefore the reasons are very interesting.

While it’s sometimes classified as a spiral nebula almost like our own Milky Way it’s also sometimes classified as a lenticular galaxy,” the agency says. “Lenticular galaxies are a galaxy type that sits between spiral and elliptical varieties.” Now, that creates it more complex, right?

But here’s an easier way of watching it. NASA says the galaxies grow even as we do. “While the spiral arms of this galaxy are distinguishable, they are not clearly defined. Pictured here, the tip of 1 arm appears to be diffused,” it says.

These galaxies are in good company 💫

The @NASAHubble Wide Field Camera 3 captured this image of a trio of galaxies — the second two galaxies can be spotted on the far right and bottom center. Discover what makes these galaxies unique:

Galaxies aren’t static, and their morphologies (and therefore their classifications) vary throughout their lifetimes, says NASA during a separate note published on its website.

“Spiral galaxies are thought to evolve into elliptical. this will happen by merging with each other , 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 spiral nebula NGC 4680 within the 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 referred to as SN 1997bp, says NASA.

NASA shared an equivalent picture on Twitter also and a user wondered if the space agency ever flirted with the thought of sending its astronauts to at least one of those galaxies.

Another user, though, explained why it had been nearly impossible for NASA to undertake any such mission.

The Hubble telescope, which captured the image , was launched in 1990 as a collaboration project between NASA and therefore the European Space Agency. The telescope has an unobstructed view of the universe.
