Can we resolve these individual orphan stars? Or just see the cumulative glow from a lot of them?
- PeterCorless 2y agoNote that there are two different announcements today, and I need to clarify my comment above. • One piece cited viewing 1.5 trillion stars in the Perseus cluster of galaxies, which is 240 million ly distance: https://www.nottingham.ac.uk/news/first-pictures-from-euclid-satellite-reveal-billions-of-orphan-stars https://www.nottingham.ac.uk/news/first-pictures-from-euclid... • The other cited spotted stars in galaxy cluster Abell 2390, which is in the Pegasus constellation, which is 2.7 billion ly away — an order of magnitude further away: https://www.esa.int/Science_Exploration/Space_Science/Euclid/ESA_s_Euclid_celebrates_first_science_with_sparkling_cosmic_views https://www.esa.int/Science_Exploration/Space_Science/Euclid... If I am reading this correctly, it seems like Euclid was able to see the light from individual stars ripped from their galaxies in Abell 2390. Which is quite the accomplishment. Please let me know if I am reading too much into this, or reading it incorrectly.
