Flying on Planet-Forming Wings
ESO Picture of the Week | 2021 Feb 22

Image Credit: ESO/Ginski et al.

---

Appearing as a bird in flight, with wings outstretched in the expanse of space, SU Aur, a star much younger and more massive than the Sun, is surrounded by a giant planet-forming disc. This image, captured by the SPHERE instrument on ESO’s Very Large Telescope (VLT), shows the disc around SU Aur in unprecedented detail, including the long dust trails connected to it. The star itself is obscured by the instrument’s coronagraph, a device that blocks the light from the central star to allow the less bright features around it to stand out.

The dust trails are composed of material from an encompassing nebula flowing into the disc. This nebula is likely the outcome of a collision between the star and a huge cloud of gas and dust, resulting in the unique shape of this planet-forming disc and the surrounding dust structure. A new study of SU Aur, which used the VLT and data from other telescopes, including the Atacama Large Millimeter/Submillimeter Array (ALMA), showed that the nebula is still feeding material to the planet-forming disc. These new observations highlight how complex planet-forming discs can be.

This NASA/ESA Hubble Space Telescope Picture of the Week features NGC 4826 — a spiral galaxy located 17 million light-years away in the constellation of Coma Berenices (Berenice’s Hair). This galaxy is often referred to as the “Black Eye”, or “Evil Eye”, galaxy because of the dark band of dust that sweeps across one side of its bright nucleus.

NGC4826 is known by astronomers for its strange internal motion. The gas in the outer regions of this galaxy and the gas in its inner regions are rotating in opposite directions, which might be related to a recent merger. New stars are forming in the region where the counter rotating gases collide.

This galaxy was first discovered in 1779 by the English astronomer Edward Pigott.

Stephan's Quintet - Galaxy mergers

I present a new look at Stephan's Quintet galaxies, imaged by Hubble Space Telescope and processed by myself, Roi Levi.

These five galaxies are “Stephen’s Quintet”, also known as Hickson Compact Group 92, and were photographed from the new Wide Field Camera 3 (WFC3) aboard NASA's Hubble Space Telescope.

Pictured are, clockwise from upper left, NGC 7320, NGC 7319, NGC 7318a, NGC 7318b, and NGC 7317.

The two galaxies in the center, NGC 7318a and NGC 7318b are galaxies in the merging process and they will eventually become one galaxy.

Galaxy mergers can occur when two or more galaxies collide and these are now in the most violent type of galaxy interaction. The gravitational interactions between galaxies and the friction between the gases and dust majorly effects the galaxies involved in the merge.
It is most likely that the whole group of five will merge with each other and form one galaxy over time.
