Cosmic Wonders The Vibrant Universe of NGC 6822

Описание: Discover the intriguing galaxy NGC 6822 through the lens of the Webb Telescope, combining NIRCam and MIRI data for a stunning composite view. This irregular galaxy is adorned with a dense array of stars, appearing as white specks against greenish-yellow clouds of gas and dust. Some stars stand out with diffraction spikes, resembling snowflakes, while the clouds vary from patchy wisps to denser areas glowing yellow. Reddish hues highlight distant galaxies amidst this stellar backdrop. NGC 6822 is notably low in "metallicity," meaning it's scarce in elements heavier than hydrogen and helium, offering a glimpse into the conditions of the early universe before stars created heavier elements. Webb's NIRCam cuts through the cosmic fog to reveal numerous stars, while MIRI shines a light on the galactic dust, helping us understand more about stellar and dust formation in the nascent cosmos.
