🆕 The NASA/ESA Hubble Space Telescope has watched an early galaxy transforming its neighbourhood!⁠ ⁠ 🔴 The galaxy MXDFz4.4 existed just 1.4 billion years after the Big Bang, at the end of the Era of Reionisation, a period in our Universe during which the ‘fog’ that filled space 😶‍🌫️ became transparent or ionised. Astronomers are still trying to understand how this happened. ⁠ ⁠ 🔴 MXDFz4.4 contains tightly clustered young stars shining with ultraviolet light capable of ionising this opaque gas. This suggests that similar galaxies in the early Universe were responsible for the Era of Reionisation!⁠ ⁠ 🔴 Alongside Hubble, astronomers also used observations from esawebb (near-infrared light) and the esoastronomy Very Large Telescope (visible light).⁠ ⁠ For more information check the link in bio.⁠ ⁠ 📷 NASA , europeanspaceagency , STScI, I.
