The galaxy “NGC 4535” in the constellation Virgo was observed by Webb and Hubble using two space telescopes. The Universe Gateway website

This is NGC 4535, a spiral galaxy located about 50 million light-years away in the constellation Virgo. It was created based on data acquired by the Near-Infrared Camera (NIRCam) and the Mid-Infrared Observing Instrument (MIRI) of the James Webb Space Telescope (JWST). Because the Webb Space Telescope primarily observes infrared wavelengths that cannot be seen by the human eye, the colors of published images are colored according to the filters used during acquisition.

According to the Space Telescope Science Institute (STScI), which operates the Webb Space Telescope, the NIRCam data (colored in blue and green) show that infrared radiation from hot young stars that appear blue in visible light is compared to the MIRI data (colored in green) And red).(Colored) shows the infrared rays radiated by dust that has absorbed ultraviolet and visible rays. The dust spread throughout the galactic disk is distributed like a skeleton supporting spiral arms, and hot stars are distributed along it, gathering densely here and there to form star clusters.

The next image is NGC 4535, observed by the Hubble Space Telescope's (HST) Wide Field Camera 3 (WFC3). The orientation and size have been modified to match the previously published Webb Space Telescope image, so some data may be missing. Comparing the two images, we can see that the bright part of the dust distribution captured by the Webb Space Telescope is spread out along the chain of dark nebulae seen in the Hubble Space Telescope image.

The observation of NGC 4535 was carried out by the Webb Space Telescope as part of the PHANGS (Physics at High Angle Resolution in Nearby Galaxy) observing project, which targets galaxies in the nearby Universe. This project, which includes the Hubble Space Telescope, the ALMA radio telescope array in Chile, and the European Southern Observatory's (ESO) Very Large Telescope (VLT) at the Paranal Observatory in Chile, will provide high-resolution observations using electromagnetic waves of different wavelengths. They have been performed for several years to understand star formation.

The Webb Space Telescope, a new addition to the project, has observed bubble-like and thread-like structures that tell us about the star formation cycle on the smallest scale ever, surprising even researchers who have studied the same galaxy for many years. This means that there is. The image is initially one of 19 nearby galaxies observed by the Webb Space Telescope as part of the PHANGS project, and was released by STScI, the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) in January. 29, 2024.
