Hubble Spots Young Stars in 'Lost Galaxy' of Virgo
A stunning image from the NASA/ESA Hubble Space Telescope has shed new light on a distant galaxy known as NGC 4535, dubbed the "Lost Galaxy" due to its faint appearance through small telescopes. Located approximately 50 million light-years away in the constellation Virgo, this spiral galaxy is now revealing its hidden secrets thanks to Hubble's exceptional capabilities.
The latest image features vibrant young star clusters scattered across the galaxy's sweeping spiral arms, each accompanied by glowing-pink H II clouds that surround and illuminate these starry groupings. These intense radiation sources signal the presence of extremely hot and massive stars, which create powerful stellar winds as they heat up their surrounding birth clouds. This process ultimately leads to supernovae explosions.
The newly released image is part of a comprehensive observing program aimed at cataloging around 50,000 H II regions in nearby star-forming galaxies like NGC 4535. The data used for this latest release also draws from the PHANGS (Physics and Chemistry of Pulsars, High Energy Supernovae, and their Astrophysical Origins) observing program, which seeks to understand the intricate relationships between young stars and cold gas.
Hubble's exceptional mirror – spanning nearly eight feet across – allows it to observe faint galaxies like NGC 4535 with unparalleled clarity. The addition of this latest image brings new insights into our understanding of NGC 4535, revealing a previously unseen dimension in the brilliant red glow surrounding massive stars during their first few million years of life.
