This is about 22,000 light-years away in the direction of Scorpio.Spherical cluster “Tarzan 1”he is. A globular cluster is a celestial body in which tens of thousands to millions of stars are clustered into a spherical shape. About 150 globular clusters have been discovered so far in the Milky Way. It is a celestial body that shows its beauty in the contrast of colors with the bright stars that fill the entire field of view.

In the direction of Sagittarius, where the center of the Milky Way is located, and Scorpio, next to Sagittarius, there is a bulge in the center of the galaxy where stars gather.Galaxy Bolgexist. Not only stars, but also gas and dust gather in the bulge, and in the direction of Scorpio and Sagittarius, dark, dust-rich nebulae also line up like a belt.

Dust tends to absorb and scatter the light emitted by stars (particularly blue light of short wavelengths), so it can block out the light from stars or make them appear redder than they actually are. However, some wavelengths, such as visible red light and near-infrared light, pass through dust relatively easily, making it useful for observing objects outside of dust.

this pictureHubble Space Telescopemounted on“Advanced Comet-Catching Monitoring (ACS) Camera”And theWide Field Camera 3 (WFC3)It was created based on images obtained using a total of 3 types of visible and infrared light filters. Since the human eye cannot capture infrared light, a color image is created by coloring and synthesizing the monochrome image obtained through the filter with blue, green, and red in order of the shortest wavelength.

ACS and WFC3 are cameras modified on the space shuttle service mission after the launch of the Hubble Space Telescope in April 1990. The Hubble Space Telescope was installed before WFC3 was installedWide Field Camera 2 (WFPC2)

Tarzan 1 was installed, but Tarzan 1 was also imaged by the Hubble Space Telescope when WFPC2 was used. The image at the end of this article shows Tarzan 1 captured using WFPC2. As noted by the European Space Agency (ESA), which published the image, compared to the Tarzan 1 image that was first published, the performance of the Hubble Space Telescope has improved, with a camera that combines a wider field of view and better resolution. you can feel it.*… ACS is the mission of STS-109 from Colombia in March 2002, and WFC3 isIn the form of replacing WFPC2

It was installed on the STS-125 mission by Atlantis in May 2009.

The first image was released by the European Space Agency on October 10, 2022 under the title
