NASA Astronomy Photo of the Day 20 February 2023: Our universe is illuminated by trillions of stars in the sky. These vivid objects are fashioned in a giant cloud of dust and gasoline in place, recognized as a Nebula. Immediately after development, quite a few stars sort teams from the similar Nebula, forming a Star Cluster. Star clusters can consist of as number of as 10 stars or as a lot of as hundreds of thousands of stars. In some cases, sky watchers might confuse star clusters in our individual Milky Way Galaxy with clusters in other galaxies because of to their identical visual appearance.
A person of these star clusters is NGC 1850, which tends to make NASA’s Astronomy Photo of the Day. It is a 100-million-12 months-outdated globular star cluster located 160,000 light-weight-a long time absent in the constellation Dorado. What is actually unusual about this star cluster is its dimension and form is reminiscent of the other ancient star clusters in the Milky Way Galaxy. Having said that, this double star cluster is not existing in our galaxy. Rather, it belongs in the Significant Magellanic Cloud.
NGC 1850 is a spherical collection of densely packed stars held collectively by mutual gravitational attraction. Not like most globular clusters, however, the stars of NGC 1850 are comparatively young. Globular clusters with younger stars these as NGC 1850 are not present in our have Milky Way galaxy.
The image was captured by the Hubble Place Telescope, which is run by NASA and ESA in collaboration. This proves but yet again that the area telescope could possibly be previous, but it is even now capable of capturing breathtaking images of celestial objects situated even tens of millions of gentle-several years absent.
NASA’s description of the picture
There is absolutely nothing like this ball of stars in our Milky Way Galaxy. This is astonishing because, at initially look, this showcased graphic by the Hubble House Telescope implies that star cluster NGC 1850’s size and condition are reminiscent of the lots of ancient globular star clusters which roam our individual Milky Way Galaxy’s halo. But NGC 1850’s stars are all also younger, creating it a kind of star cluster with no recognized counterpart in the Milky Way. Moreover, NGC 1850 is also a double star cluster, with a next, compact cluster of stars noticeable in this article just to the appropriate of the substantial cluster’s heart. Stars in the large cluster are believed to be 50 million several years youthful, while stars in the compact cluster are younger nevertheless, with an age of about 4 million many years.
A mere 168,000 mild-a long time distant, NGC 1850 is located in close proximity to the outskirts of the Large Magellanic Cloud galaxy. The glowing gasoline filaments throughout the graphic still left, like supernova remnants in our very own galaxy, testify to violent stellar explosions and point out that limited-lived massive stars have a short while ago been current in the area.

Source backlink Today, the National Aeronautics and Space Administration (NASA) officially released an incredible astronomy picture of the day captured by the Hubble Telescope.
On February 20th, 2023 Hubble Telescope was aimed at one of the most outstanding astronomical views in the night sky, a double star cluster. The photo that was taken is absolutely stunning and provides a detailed view of the two distinct star clusters lying at the heart of extremely large and active stellar nursery in the southern sky.
The star cluster, also known as NGC 1818, can be seen several light years away from its closest neighbor, the 30 Doradus Nebula, in the Large Magellanic Cloud galaxy. According to studies conducted by NASA, the double star cluster is believed to be slightly younger than the nearby 30 Doradus Nebula.
When Hubble Telescope captured the view, it revealed NGC 1818 to be composed of two different stellar populations. The stars in the larger-scale background are mostly comprised of youngsters; Population,. The stars that are more centrally located are the older, redder members of population II.
NASA’s astronomers noted that the two distinct populations of stars in the cluster suggest that NGC 1818 has evolved through two major formation events. The cluster’s two components probably represent two separate generations of stars that were initially part of two different stellar nurseries.
The Hubble images will help astronomers pinpoint how clustered stars can be so different from one another while residing in the same region of space.
Overall, this is an incredible image to capture, and provides important insight into the evolution of stars. To view the newest NASA Astronomy Picture of the Day for February 20th, 2023, please visit the official NASA website.
