Hubble Captures 12 Interacting Galaxies That Look Like a String of Pearls

Hubble Interacting Galaxies String of Pearls
NASA’s Hubble Space Telescope captured 12 interacting galaxies with long, tadpole-like tidal tails of gas, dust, and stars that resemble a string of pearls. More specifically, the tails contain 425 clusters of newborn stars, with each one consisting of as many as 1-million of them.

Clusters in tidal tails have been studied for decades, as when galaxies interact, gravitational tidal forces pull out long streamers of gas and dust. They look like as if someone is taking a galaxy’s spiral arm and stretching them out into space, with the exterior part getting pulled like taffy from the gravitational tug-of-war between interacting galaxies.

It’s a surprise to see lots of the young objects in the tails. It tells us a lot about cluster formation efficiency. With tidal tails, you will build up new generations of stars that otherwise might not have existed,” said Michael Rodruck, Lead Author from the Randolph-Macon College.

Hubble Interacting Galaxy System Arp-Madore 2105-332
NASA / ESA’s Hubble Space Telescope observes an interacting galaxy system known as Arp-Madore 2105-332, which is located approximately 200 million light-years from Earth in the constellation Microscopium. This system is positioned in such away that the smaller galaxies appear to be forming a line that approaches the leftmost component of Arp-Madore 2105-332, known individually as 2MASX J21080752-3314337.

If you look closer at the pair of interacting galaxies, one smaller than the other, each features a bright spot at the center as well as two loosely-wound spiral arms, with threads of dark dust following the arms. They appear as a broad, soft glow, making it hard to identify individual stars, while a number of bright stars and smaller background galaxies can also be seen.

As with many galaxy types, categorising a galaxy as an emission-line galaxy does not exclude it from having other descriptions that refer to its other properties. Arp-Madore 2105-332, for example, is also a ‘peculiar’ galaxy, reflecting the atypical shapes of its two constituent galaxies,” said the ESA.
