Photograph of the globular cluster “Tarzan 4” in “Scorpio” by the Hubble Space Telescope | Sorae Gateway site to the universe

This one is in the constellation ScorpioGlobal cluster “Tarzan 4”in. The contrast of the colors of the stars shining in the whole field of view makes you feel beautiful. A globular cluster is a celestial body where tens of thousands to millions of stars are gathered in a spherical shape. About 150 globular clusters have been discovered so far in the Milky Way galaxy.

In the direction of Sagittarius, where the center of the Milky Way Galaxy is located, and Scorpio, which is next to Sagittarius, there is a bulge in the center of the galaxy where stars are collected.“Galaxy Crash”There are. Not only stars but also gas and dust gather in the bulge, and in the direction of Scorpio and Sagittarius, dark nebulae full of dust also accompany the belt.

dustforlight emitted from a star(especially blue light with a short wavelength)absorption/scatteringBecause it has the property that it is easy to do, it blocks the light from the star or makes it look redder than it really is. anyway,Visible red light and near infrared lightThere are some wavelengths such asRelatively easy to pass through dustTherefore, it is useful for observing celestial objects beyond the dust.

This image is“Hubble”mounted on a space telescope“Advanced camera for observing comet hunting (ACS)”a“Wide field camera 3 (WFC3)”It was created based on images acquired using , using a total of 3 types of visible light and infrared filters. Since the human eye cannot capture infrared light, the monochrome images obtained through the filter are colored blue, green and red, respectively, and then synthesized.

According to the European Space Agency (ESA), which released the images, observations of Tarzan 4 by the Hubble Space TelescopeShape, Density, Age and Structure of a Globular Cluster Near the Center of the Milky WayIt was carried out as part of a study to understand The first image was released by ESA on September 12, 2022 as one of the Hubble Space Telescope images of the week.
