The “NGC 1365” galaxy in the Fornax constellation was observed by Webb and Hubble using two space telescopes. The Universe Gateway website

This image captures the center of the barred spiral galaxy NGC 1365, located about 56 million light-years away in the Fornax constellation. 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.

وفقًا لمعهد علوم التلسكوب الفضائي (STScI)، الذي يقوم بتشغيل تلسكوب ويب الفضائي، تُظهر بيانات NIRCam (الملونة باللونين الأزرق والأخضر) أن الأشعة تحت الحمراء المنبعثة من النجوم الشابة الساخنة التي تظهر باللون الأزرق في الضوء المرئي تتم مقارنتها ببيانات MIRI (الملونة) باللونين الأخضر والأحمر).(ملون) يُظهر الأشعة تحت الحمراء التي يشعها الغبار الذي امتص الأشعة فوق البنفسجية والضوء المرئي. وينتشر الغبار مثل هيكل عظمي يدعم الأذرع الحلزونية، وتتجمع النجوم الساخنة بكثافة هنا وهناك لتشكل مجموعات نجمية.

الصورة التالية هي NGC 1365، والتي تم رصدها بواسطة الكاميرا واسعة المجال 3 (WFC3) التابعة لتلسكوب هابل الفضائي (HST). تم تعديل الاتجاه والحجم ليتوافق مع صورة Webb Space Telescope التي تم نشرها سابقًا، لذلك قد تكون بعض البيانات مفقودة.

By comparing the two images, you can see that the dust distribution captured by the Webb Space Telescope appears as a series of dark nebulae in the Hubble Space Telescope image. In addition, the central region, where many ancient stars are concentrated and where a supermassive black hole is thought to be lurking, is bright in Either way, but diffraction spikes occur when the light source is very bright and compressed.(※)It only occurs in Webb Space Telescope images.

*… The diffraction height is a beam of light produced by the telescope structure. For example, the Hubble Space Telescope (HST) has a cross-shaped diffraction spike, while the Webb Space Telescope has hexagonal mirror segments that form the primary mirror and three that support the secondary mirror, and has a unique shape that combines diffraction spikes caused by book supports.

The observation of NGC 1365 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.
