Irregular Galaxy Shows the Picture of Vastness of the Nature

The celestial beauty known as NGC 7292, nestled within the frame of this picture, stands as a testament to the vastness of our universe. Unlike its spiral counterparts, NGC 7292 defies convention with its unique morphology.

Its core gracefully extends, forming a distinctive bar-shaped structure that sets it apart.

Moreover, NGC 7292 exudes an intriguing dimness, earning the epithet of a low surface brightness galaxy.

Such galaxies, dominated by interstellar gas and enigmatic dark matter, often play host to stellar mysteries yet to be fully unraveled.

Hubble Captured Irregular Galaxies

Guided by their insatiable thirst for knowledge, astronomers directed the Hubble telescope toward NGC 7292.

This endeavor was part of a comprehensive observational program delving into the aftermath of Type II supernovae to unravel their intriguing diversities.

These cataclysmic events occur when massive stars, having exhausted their nuclear fuel, collapse, only to violently rebound in a brilliant explosion that tears the stellar fabric asunder.

Among the many celestial phenomena that have graced NGC 7292, one event stands out in astronomical annals—SN 1964H. Discovered by keen-eyed scientists in 1964, this supernova is a remarkable milestone in our quest to comprehend the cosmos.

By scrutinizing the surrounding stellar companions of SN 1964H, astrophysicists can glean insights into the star’s magnitude before its cataclysmic demise.

Furthermore, these meticulous observations promise to unveil other remnants of stellar companions that once shared a celestial dance with the progenitor of SN 1964H.

Why is Irregular Galaxy Called So?

Any galaxy that does not easily conform to the categories outlined in the Hubble classification scheme is called an irregular galaxy.

These galaxies lack a distinct shape or structure, and they may have originated from collisions, encounters with other galaxies, or intense internal disturbances.

What are the Main Parts of an Irregular Galaxy?

A disk is present in irregular galaxies, but spiral arms are absent.

Nonetheless, these galaxies exhibit a blend of both mature and youthful stars alongside abundant gas and dust.

How Many Stars Are in Irregular Galaxy?

A disk is present in irregular galaxies, but spiral arms are absent. Nonetheless, these galaxies exhibit a blend of both mature and youthful stars alongside abundant gas and dust.

What is the Best Known Irregular galaxy?

The Large and Small Magellanic Clouds, commonly called LMC and SMC, respectively, are among the most recognizable irregular galaxies.

These galaxies can be seen as compact luminous clouds in the Southern Hemisphere’s night sky, even without the aid of telescopes.

What are irregular galaxies filled with?

Like spiral galaxies, irregular galaxies frequently contain substantial amounts of gas, dust, and numerous vibrant young stars.

Approximately 20% of galaxies nearby are classified as irregular galaxies. On the other hand, quasars are concentrated regions situated at the galaxy’s core, emitting tremendous levels of energy.

This NASA/ESA photograph of the Hubble Space Telescope shows the serenely drifting jellyfish galaxy JW39. This galaxy, one of many jellyfish galaxies Hubble has observed over the past two years, lies around 900 million light-years away in the constellation Coma Berenices.

What are the effects of galaxy clusters on the shape and gas content of galaxies?

Although it seems serene, this jellyfish galaxy is actually drifting in a galaxy cluster, which is an extremely dangerous environment. The gravitational attraction of larger companions frequently warps galaxies in galaxy clusters, twisting them into a variety of designs.

Additionally, a searingly hot plasma known as the intrascluster medium dominates the area between galaxies in a cluster. Despite the extreme thinness of this plasma, galaxies moving through it have an almost current-like sensation, and this interaction can deplete galaxies of star-forming gas.

What Phenomenon Creates the Distinctive Trailing Tentacles in Jellyfish Galaxies?

Ram-pressure stripping, or the interaction between the intracluster medium and the galaxies, is what causes the jellyfish galaxy’s trailing tentacles. As JW39 traveled through the cluster, the intracluster medium’s pressure sucked away gas and dust, creating long trailing ribbons of star formation that now extend away from the galaxy’s disk.

What is the impact of harsh environments on star formation in drifting jellyfish galaxy?

Astronomers used Hubble’s Wide Field Camera 3 to investigate these trailing tendrils in great detail because they represent a particularly hostile environment for star formation.

Surprisingly, researchers found little difference between star production in the galaxy disk and star formation in the ‘tentacles’ of drifting jellyfish galaxies.

Hubble Space Telescope Captures Drifting Jellyfish Galaxy That are Located Over 900 Million Light-Years Away

The drifting jellyfish galaxy JW39, located in the constellation Coma Berenices and situated over 900 million light-years away, has been captured by NASA/ESA’s Hubble Space Telescope.

This peculiar galaxy finds itself adrift within a galaxy cluster. In such clusters, the gravitational forces exerted by larger neighboring galaxies often cause distortions, resulting in galaxies assuming various shapes.

Furthermore, the space between galaxies within the cluster is influenced by a scorching-hot plasma known as the medium.

While this plasma may be tenuous, galaxies moving through it experience its effects akin to a swimmer battling against a strong current, resulting in the stripping away of their star-forming gas.

This view from the NASA/ESA Hubble Space Telescope shows the globular cluster NGC 6325, which is closely packed.  Glistening Star Cluster is located in the constellation Ophiuchus, approximately 26,000 light-years from Earth.


How do astronomers use globular clusters to study the birth of stars?

Globular clusters, such as NGC 6325, are tightly bonded groups of stars with tens of thousands to millions of members. They can be found in all kinds of galaxies and serve as real-world research facilities for astronomers who investigate the birth of stars. Because the constituent stars of globular clusters tend to develop at around the same time and with comparable starting compositions, astronomers may use them to fine-tune their theories of how stars grow.

Why did astronomers focus on

 examining this particular cluster?

Astronomers examined this particular cluster

 in order to find a hidden monster rather than to understand star formation better. Though it appears to be serene, astronomers believe this cluster contains an intermediate-mass black hole that subtly alters nearby stars’ velocity. Previous research discovered that the dispersion of stars in some highly concentrated globular clusters – those with stars packed relatively tightly together – differed slightly from what astronomers predicted.

How did researchers investigate the possibility of a black hole in NGC 6325?

This discrepancy shows that a black hole may be hiding at the center of at least part of these tightly packed globular clusters, maybe NGC 6325. To investigate this concept further, researchers used Hubble’s Wide Field Camera 3 to observe a broader sample of densely packed globular clusters, including this star-studded image of NGC 6325. This image also includes data from Hubble’s Advanced Camera for Surveys.
