near the center of barred spiral galaxy NGC 5068 in the constellation Virgo observed by the Webb Space Telescope | Surrey portal site to the universe

This is a view of the center of barred spiral galaxy NGC 5068 located about 17 million light-years away in the direction of Virgo. It was created based on data obtained by the James Webb Space Telescope’s Near Infrared Camera (NIRCam) and Medium Infrared Observatory (MIRI).（※）. A narrow spiral galaxy is a spiral galaxy that has a ribbon-like structure at its center. About half of all spiral galaxies, including our own Milky Way, are thought to have bar-like structures.

* … Because the Webb Space Telescope primarily monitors infrared wavelengths that the human eye cannot see, the colors in the published images are those that are colored in according to the filters used at the time they were acquired. In this image, 2.0 µm blue, 3.0 µm green, 3.35 µm orange, 3.6 µm red, 7.7 µm magenta, 10 µm cyan, 11 µm yellow, and 21 µm red.

According to the European Space Agency (ESA), NIRCam, which observes near-infrared, near-visible light, has captured many of the stars that make up NGC 5068 and the young starlit gas clouds that formed within it. more. The star density is highest in the bar-like structure at the center of the galaxy at the upper left of the image, and decreases toward the spiral arms. On the other hand, MIRI, which uses mid-infrared light at longer wavelengths, captured the appearance of concentrated dust as the frame supporting the galaxy, and the glowing, bubble-like structure of gas.

The observation of NGC 5068 was carried out by the Webb Space Telescope as part of the “PHANGS” (Physics at High Angle Resolution in the Nearby GalaxieS) observational project, which targets galaxies in the nearby universe. The PHANGS project includes the Hubble Space Telescope, the ALMA radio telescopes in Chile, and the European Southern Observatory’s (ESO) Very Large Telescope (VLT) at Paranal Observatory in Chile. High-resolution observations using electromagnetic waves of various wavelengths have been made for several years to understand star formation in galaxies.

Stars and planetary systems form in gaseous clouds that collect gas and dust, and dust has the property of blocking visible light. The European Space Agency says the Webb Space Telescope’s ability to observe in infrared wavelengths, which are not obscured by dust, is ideal for studying the star formation process beyond dust. The image of NGC 5068 taken by the Webb Space Telescope was released by the European Space Agency on June 2, 2023 as the Webb Space Telescope Picture of the Month.
