Astronomy Picture Of The Day: Sombrero Galaxy (M104)


Black Hole@konstructivizm

NASA's James Webb Space Telescope (JWST) has used its NIRCam (Near-Infrared Camera) to capture images of the Sombrero Galaxy (M104), revealing fine details of dust in its outer rings, which are blocking starlight. Located 30 million light-years away in the constellation Virgo, this 'side-on' galaxy is home to about 2,000 globular clusters glowing in near-infrared, and the new information will help us understand its structure and evolution. The NIRCam image shows for the first time the intricate clumping within the dust disk, which previously appeared smooth in infrared images from the Spitzer Space Telescope. Compared to the visible light image from Hubble, dust in this NIRCam infrared image does not block as much light, because the longer, redder wavelengths of light from stars can pass through the dust more easily. The high resolution allows thousands of old, red giant stars to be seen in the galaxy's central bulge, which is an important part of studying galaxy evolution. The NIRCam observation is a follow-up to a 2024 observation by JWST's MIRI (Mid-Infrared Instrument), which sheds light on the bright dust and inner disk. The Sombrero Galaxy lies at the edge of the Virgo galaxy cluster and has a mass of about 800 billion suns. M. Garcia Marin of the Space Telescope Science Institute led the observation.
