Nebulae come in all sorts of colors. In this sense, there are some in particular that have a characteristic and well-known color, but when seen in the sky, they take on a dreamlike quality; I'm talking about pink galaxies.
Likewise, astronomers at the Space Telescope Science Institute in Baltimore pointed the Hubble Space Telescope at a pair of particularly favorable galaxies cited as Arp 273. Similarly, the largest of the pink spiral galaxies , known as UGC 1810, has a ring that is distorted in a pinkish hue, caused by the gravitational affinity of the outflow from its companion galaxy, and which is located just below it; this is also popularly known as UGC 1813.
Similarly, this graphic is a composition of the Hubble Wide Field 3 camera with fundamentals obtained on December 17, 2010, with three separate filters that achieve a wide hierarchy of wavelengths encompassing the ultraviolet spectrum, with shades of red and blue.
In light of the above, the Hubble Space Telescope was launched on April 24, 1990, aboard the Space Shuttle Discovery during NASA's STS-31 mission. The revelations from the Hubble Telescope have revolutionized nearly every aspect of celestial research, from general science to cosmology. Furthermore, one of the findings related to pink galaxies is that an audiovisual presentation revealed them to resemble an autumn night sky containing the constellations of Andromeda, Perseus, and Triangulum.
In this vein, the video zooms in on an area of the sky located between the " Demon Star ," highlighting Algol on the left, and the star Almaak on the right. Furthermore, by using the zoom function, our perspective delves deeper into the universe , revealing a world filled with celestial bodies invisible to the naked eye.
New Findings About Pink Galaxies
On the other hand, further along, a major spiral galaxy appears, along with another slightly smaller one, but when joined together we can see an S-shaped representation. Similarly, the Arp 273 galaxies are located at what would be about 300 million light-years from the Milky Way.
Facts about the Arp 273 galaxies
One of the revealing facts about the Arp 273 galaxies is that they are always in a state of interaction. That is, first, we zoom in on the smaller segment of the pair. Here, we see a galaxy almost edge-on, showing clear signs of intense star formation along its axis. This was perhaps triggered by a collision with its previous companion galaxy .
Also, the tidal forces of the smaller companion galaxy and its gravitational pull have caused the pair to feign an ensemble in the form of a pink hue, designated "space pink."
One of the pink galaxies
According to various versions given by scientists specializing in the subject, there are several types of pink galaxies that present really specific characteristics, these are.
Boomerang Nebula
One of the main pink galaxies is the Boomerang Galaxy, which is classified as a proto- universe nebula in the constellation Centaurus, located approximately 5000 light-years from Earth. In this sense, it is characterized as a star or celestial system that is continuously progressing toward the stage of a celestial nebula. It was designated as such by scientists Keith Taylor and Mike Scarrot in 1980 when they were able to observe it using the Anglo-Australian Telescope.
Furthermore, astronomers, upon first observing it, noticed a slight irregularity in the waves, suggesting a curved profile similar to a boomerang. In contrast, the much more valuable image obtained with the Hubble Space Telescope reveals it as a bipolar galaxy, thus earning it the nickname "Bowtie Nebula."
Formation of the Boomerang Nebula
On the other hand, the nebula was created from gas ejected by its central star. Therefore, it has been shedding gas at a rate of one-thousandth of the Sun's mass each year for at least 1500 years. This also means that it is losing mass 10 to 100 times faster than other similar objects.
Furthermore, the gas diffuses very rapidly (164 km/s), resulting in a low temperature. Thus, there is an outer layer that diffuses at 35 km/s, which may be a consequence of the exclusion of a typical outer shell by a two-core star.
Features of the Boomerang Nebula
Some of the characteristics of this type of pink galaxy are the following:
1. It is considered the coldest place in the cosmos
Why this nebula is the coldest zone in the entire cosmos has a very simple principle. Like any refrigerator cabinet, the nebula lets gas diffuse, causing it to freeze mechanically.
2. Stars who die
In this regard, the scientist Carl von Linde licensed a simpler, similar technology in 1926. The importance of this discovery lies primarily in establishing what happens to stars once they die, as will happen with the Sun. Several of the processes that occur upon a star's death have been observed in various celestial bodies. Now, thanks to the Boomerang Nebula, we can perceive just how cold the future of our solar system and the cosmos may be.
Conclusions about pink galaxies
Years ago, specifically on the 21st anniversary of the Hubble Space Telescope's ejection in April 2011, researchers from the Space Telescope Science Institute pointed Hubble's lens toward a fundamentally favored group of interacting galaxies cited as Arp 273.
Likewise, the largest of the pink spiral galaxies, popularly known as UGC 1810, has a ring that is undoubtedly caused mainly by each of the tidal forces that have deformed it to achieve a pink appearance with a beautiful galactic rose shape. This phenomenon originates from the gravitational pull of the companion galaxy located below it, known as UGC 1813.
On the other hand, the smaller galaxy shows clear signs of sharp stellar alignment at its focus, perhaps excited by the collision with the galaxy that will become its companion. Likewise, each of the clusters that make up an inner component of the spiral arms is largely unknown, with one arm showing evidence of the dent on its back side and returning on the other. Similarly, the interaction between each of the galaxies was observed on December 17, 2010, using the Hubble Telescope.
Finally, it is important to highlight that among the findings that each of the scientists who brought these discoveries to life, in the Hubble telescope image , after a constitution of testimonies, imprisoned with three separate filters in the WFC3 camera and that allow an extensive range of wavelengths, encompassing the ultraviolet and each of the fascinating parts of the pink galaxies.
