NASA Explains Why Some Galaxies Can’t Always Have A Single Name

NASA has shared an interesting {photograph} that includes three completely different galaxies. And with that, the area company has additionally defined how these galaxies do not let any “labels define them”. Confused? Let’s unpack. On June 13, NASA posted {a photograph} of three galaxies — one proper within the centre and the opposite two noticed on the intense proper and backside of the image. The picture was captured by the wide-field digital camera three of NASA’s Hubble telescope. Now, let’s perceive what makes these galaxies distinctive. In its Instagram publish, the company stated that the galaxy pictured within the center was “difficult to classify” and the explanations are very fascinating.

While it’s generally categorised as a spiral galaxy, much like our personal Milky Way, it is usually generally categorised as a lenticular galaxy,” the agency says. “Lenticular galaxies are a galaxy sort that sits between spiral and elliptical varieties.” Now, that makes it more complex, right?

But here’s a simpler way of looking at it. NASA says the galaxies grow just as we do. “While the spiral arms of this galaxy are distinguishable, they don’t seem to be clearly outlined. Pictured right here, the tip of 1 arm seems to be subtle,” it says.

Galaxies usually are not static, and their morphologies (and subsequently their classifications) range all through their lifetimes, says NASA in a separate word revealed on its web site.

“Spiral galaxies are thought to evolve into elliptical. This can occur by merging with each other, inflicting them to lose their distinctive spiral construction,” NASA says further in its Instagram post, explaining how even the galaxies change their composition with time.

The agency says that the spiral galaxy NGC 4680 in 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 known as SN 1997bp, says NASA.

NASA shared the same picture on Twitter as well and a user wondered if the space agency ever flirted with the idea of sending its astronauts to one of these galaxies.

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

Here are some more Twitter reactions to the picture:

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