A new photo of the Sombrero galaxy from @NASAWebb
NASA’s James Webb Space Telescope recently imaged the Sombrero galaxy with its MIRI (Mid-Infrared Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring. This image includes filters representing 7.7-micron light as blue, 11.3-micron light as green, and 12.8-micron light as red. Researchers say the clumpy nature of the dust, where MIRI detects carbon-containing molecules called polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions. However, unlike some galaxies studied with Webb, including Messier 82, where 10 times as many stars are born than the Milky Way galaxy, the Sombrero galaxy is not a particular hotbed of star formation. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year.

Nothing excites a lecturer more than walking into a room and seeing three whole blackboards to work with 🤩 #ToTheBlackHoleAndBack #academia
