Hubble spies "Two-Face" galaxy that suffered a glancing blow

A cosmic hit-and-run some 30 million light-years away has left one galaxy with an identity crisis.

For billions of years, the now-irregular NGC 4485 lived a nice and normal life as a standard spiral galaxy located in the constellation Canes Venatici (the Hunting Dogs). Then, a few million years back, NGC 4485 experienced a near-miss when the equivalent of a galactic semi-truck (NGC 4490) careened past it, creating a gravitational wake that wreaked havoc for both parties.

The result? Based on a new image captured by the Hubble Space Telescope's Wide Field Camera 3 and Advanced Camera for Surveys, one side of NGC 4485 still looks much like it did before the close encounter. But the other side…not so much.

As you can see in the above image, the left side of NGC 4485 still has hints of its original spiral structure. But NGC 4485's right side — which was closer to the larger galaxy NGC 4490 during the cosmic drive by — has taken on a new form altogether.

Thanks to the gravitational tug-of-war between the two galaxies, massive amounts of interstellar gas were shoved around and compressed. This ignited a flurry of star (and presumably planet) formation in both galaxies. The evidence of this is clear when you simply look at NGC 4885.

On NGC 4485's right side, we see many areas bursting with hot, young, blue stars that formed out of the newly mixed gas. This region is also speckled with bright pink nebulae that are incubating even more newborn stars. Additionally, the interaction created a 25,000-light-year stream of knotted gas and dust that links the two galaxies together.

Space Nazis!!11!!! [!--Ed.]
They form a ring around the solar system, silent sentries guarding the blazing sun, which is so distant that it looks like any other star would.

Back in the day, about 4.6 billion years ago, the solar system was little more than a cloud of cosmic dust spinning around a newborn star. Gravitational forces pulled and smoothed some of the dust into spheres—the planets and moons. The small bodies here, in a region known as the Kuiper Belt, were left out in the cold, and have remained virtually unchanged all this time.

This year, NASA stopped by. The New Horizons spacecraft flew past one of these objects, snapping pictures and collecting scientific data as it went. No space mission had ever visited a target so far away, and NASA even held a New Year’s Eve party for scientists and engineers to count down to the historic pass around midnight.

The public had many questions for them. What does this thing look like? What’s so cool about it? And why does it share a name with a term used by Nazis?

Scientists had nicknamed the object Ultima Thule, a centuries-old phrase with roots in Latin literature. For most of its long history, Ultima Thule, or the word Thule alone, has been used to describe places beyond the limits of the known world, such as hard-to-reach Arctic lands.

But the name picked up more sinister associations in recent history. During the rise of Hitler, members of the Nazi Party in Germany imagined Ultima Thule as a land of Aryan purity. In the late 1990s, white-supremacist inmates in Portland, Oregon, produced a newspaper called Thule that printed racist and anti-Semitic articles. The Swedish rock band Ultima Thule, a group popular with right-wing listeners and once sponsored by a neo-Nazi movement, released its latest album in 2015.

NGC 2903 is located about 30 million light-years away in the constellation of Leo (the Lion), and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disk galaxies. This study aimed to help astronomers better understand the relationship between the black holes that lurk at the cores of galaxies like these, and the rugby-ball-shaped bulge of stars, gas and dust at the galaxy’s center — such as that seen in this image.
