About this image

Leo Triplet & NGC3629 Tidal Stream

The Leo Triplet is a small group of galaxies composed of M65, M66 and NGC 3628. This last galaxy, also known as the Hamburger galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo.

Very interesting for the galaxy NGC 3629 result to be  its light and diffuse structures that represent the tidal stream. The Tidal tail has been drawn out of the galaxy by gravitational tides during brief and violent past interactions with its large neighbors.

The image has been taken with a C14 Edge HD and Hyperstar system f/1.9.

Astonishing Luigi !

There was a recent report (cant place it now) where a transient (SN?) was detached from any galaxy - could have been a tidal stream in there ?

Hi Tim, many thanks!

At now, i don't know the transient, but could have been.

I would like, as soon as possible for you, to know the transient SN in more detail.

Thanks again!
