Sparkling star cluster, intervening spiral galaxies – the latest images from the Hubble Space Telescope

The NASA/European Space Agency (ESA) Hubble Space Telescope has taken stunning images of the universe since it was commissioned in 1990. Recently, Hubble imaged two “interlaced spiral galaxies” located more than a billion light-years from Earth, and the “star cluster.” shining.The latter is a globular cluster.Hubble also captured a “galactic wonder” in Aries.Recently, astronomers observed in the Hubble image that a star in the constellation of Laserta outperforms the galaxy.They also found that the star is much closer than the distant galaxy.

Spiral galaxies overlap

The galaxies captured by Hubble are SDSS J115331 and LEDA 2073461. In the Hubble image, the two spiral galaxies appear to collide. However, the alignment of the two galaxies is probably just a coincidence, according to NASA. In fact, the two spiral galaxies do not interact.

The “brilliant gathering” of stars

The “brightest cluster” of stars is globular cluster NGC 6558. The Hubble Advanced Camera for Surveys recently captured the globular cluster, which is located about 23,000 light-years away in the constellation Sagittarius. The globular cluster is closer to the center of the Milky Way than the Earth.

What are globular clusters?

Globular clusters are tightly bound groups of tens of thousands to millions of stars, and are found in a wide variety of galaxies. The globular cluster depicted by Hubble is filled with stars of different colors.

Some of the brightest residents of NGC 6558 show notable diffraction elevations. These are artifacts resulting from the interaction of starlight with the support system of the Hubble secondary mirror.

According to NASA, globular clusters are interesting “natural laboratories” where astronomers can test their theories. Stars in the globular cluster form around the same time with similar elementary compositions. Therefore, these stars provide unique insights into how different stars evolve under similar conditions. The Hubble image comes from a set of observations looking at globular clusters in the inner Milky Way.

Astronomers spot the star Lacerta shining in a galaxy

The Hubble Space Telescope picked up a little-studied star in the constellation Lizard, called Lacerta, in 2017. Astronomers recently noticed that the Lacerta star outshines a galaxy in the constellation. The star is also much closer than the distant galaxy.

These stars are called “forward stars”. Astronomers who study distant objects are often not very happy with foreground stars because their bright light pollutes the faint light of distant and interesting objects they actually want to study.

Galactic Wonder in Aries

The Hubble Space Telescope recently captured an image of NGC 1156, an irregular dwarf galaxy in the constellation Aries. NGC 1156 is different from many of the galaxies familiar to Hubble. The galaxy is filled with thousands of bright stars. Ideally, the galaxy should have had a spiral shape, but NGC 1156 lacks the characteristic “zigzag” structure. The bright red flowers stand out in a galactic marvel, twisted with clouds of dust. These are regions of intense star formation, according to NASA.

NGC 1156 radiates a diffuse glow, and has a core of older, redder stars. The galactic wonder is located 25 million light-years from Earth, and has a variety of different features of interest to astronomers. A dwarf irregular galaxy is also classified as an isolated galaxy. This means that no other galaxies are close enough to affect their strange shape and ongoing star formation.

According to NASA, the maximum energy of young, newly forming stars gives the galaxy a color, as opposed to the red glow of ionized hydrogen gas. The center of NGC 1156 is densely filled with older generations of stars.

Hubble captured a galactic wonder in the past. The new Hubble image features data from a galactic void-filling program titled “Every Known Nearby Galaxy”.

According to astronomers, Hubble has observed only three-quarters of the galaxies within just over 30 million light-years from Earth in enough detail to study the formation of the stars within them. Astronomers have suggested that among the larger projects, Hubble could capture images of the remaining quarter, including NGC 1156.
