Caption This image from NASA?s James Webb Space Telescope shows a portion of the Leo P dwarf galaxy (stars at lower right represented in blue). Leo P is a star-forming galaxy located about 5 million light-years away in the constellation Leo. A team of scientists collected data from about 15,000 stars in Leo P to deduce its star formation history. They determined that it went through three phases: an initial burst of star formation, a ?pause? that lasted several billion years, and then a new round of star formation that is still continuing. The image from Webb?s NIRCam (Near-Infrared Camera) combines infrared light at wavelengths of 0.9 microns (represented in blue), 1.5 microns (green), and 2.77 microns (red). The stars in Leo P appear blue in comparison to the background galaxies for several reasons. Young, massive stars that are common in star-forming galaxies are predominantly blue. Leo P also is extremely lacking in elements heavier than hydrogen and helium, and the resulting ?metal-poor? stars tend to be bluer than Sun-like stars. A bubble-like structure at bottom center is a region of ionized hydrogen surrounding a hot, massive O-type star.

On 22 August 2024, summit staff reinstalled Rubin Observatory's commissioning camera (ComCam) on the telescope. ComCam has previously been on the telescope, but was removed before the installation of the secondary mirror in late July. ComCam ??? a smaller (144 megapixel), simpler version of the full 3200-megapixel LSST Camera ??? is being used for testing activities prior to installing the LSST Camera, anticipated to happen late 2024. In the coming weeks the summit team will install the primary/tertiary mirror, enabling ComCam to produce the first astronomical data from the Simonyi Survey Telescope.

This mosaic image of the magnificent starburst galaxy, Messier 82 (M82) is the sharpest wide-angle view ever obtained of M82. It is a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions where young stars are being born 10 times faster than they are inside in our Milky Way Galaxy.
