NASA shared a fascinating photo featuring three different galaxies. With this, the space agency also explained how these galaxies do not allow any “labels to define them.” Confused? Let’s unpack it. On June 13, NASA released a picture of three galaxies-one in the center and the other two at the far right and bottom of the picture. This photo was taken by NASA’s Hubble Telescope’s wide-angle camera3. Now, let us understand what makes these galaxies unique. The agency stated in its Instagram post that the galaxies in the middle image are “difficult to classify” for very interesting reasons.

Although it is sometimes classified as a spiral galaxy, similar to our own Milky Way, it is also sometimes classified as a lenticular galaxy,” the agency said. “A lenticular galaxy is a type of galaxy between spiral and elliptical galaxies. . “Now, that makes it more complicated, right?

But here is an easier way to look at it. NASA says that galaxies grow just like us. “Although the spiral arms of this galaxy are distinguishable, they are not clearly defined. As shown in the picture, the tip of a spiral arm seems to be diffuse,” it said.

NASA said in another article published on its website that galaxies are not static and their shape (and their classification) will change throughout their life cycle.

“Spiral galaxies are thought to evolve into elliptical galaxies. This can happen by merging with each other, causing them to lose their unique spiral structure,” NASA further said in its Instagram post, explaining how even galaxies change them over time Composition.

The agency stated that, as we explained above, the spiral galaxy NGC 4680 in the middle is flanked by two other galaxies. Interestingly, NASA stated that NGC 4680 received a wave of attention in 1997. It hosted a supernova explosion called SN 1997bp.

NASA shared the same photo on Twitter, and a user wondered if the space agency had ever considered sending astronauts to one of the galaxies.

However, another user explained why it is almost impossible for NASA to perform any such tasks.

The Hubble Telescope that took this photo was launched in 1990 as a joint project of NASA and the European Space Agency. The telescope can observe the universe at a glance.
