Star Cluster NGC 6451 in Milky Way Galaxy's Bulge | Euclid Space Telescope
.jpg)
This image shows the open star cluster NGC 6451, 8700 light-years away from us in the Scorpius constellation, observations made by the European Space Agency’s Euclid space telescope. NGC 6451 is situated south of the celestial equator. Thus, it is more easily visible from planet Earth's southern hemisphere.
The area is zoomed in ten times compared to the full image.
Image Description: A very dense field of tiny, closely packed points of light fills the image. The overall color is warm with many orange-yellow, gold and white points spread evenly across the scene. Toward the center, the stars appear more tightly clustered and brighter. A few slightly bluish points stand out among the warmer colors with no large dark patches visible.
The Euclid galactic bulge survey was conducted in early 2025 using Euclid’s optical camera VIS (monochromatic, one color). The colors were added using observations captured in summer 2025 with the Canada-France-Hawai'i Telescope's MegaCam camera (CFHT-Megacam) in Hawai’i. The colors captured by MegaCam are in optical light through three broad-band filters (u, g, and r) overlapping the very broad VIS band over the r-band. The appearance of the most luminous stars in these images varies from those generated from Euclid-only images with additional diffraction spikes and a subtle halo around the very bright stars. This a consequence of combining Euclid VIS data for their sensitivity and sharpness and CFHT-MegaCam for the colors. The distinct optical design of the two telescopes become apparent for brighter objects.
