A tiny fraction of the steellar nursery knowledge as sh2-284 is visible in this glittering, star-filled nasa hubble space telescope image. This immense region of gas and dust is the birth place of stars, which shine amon the clouds. Bright Clusters of Newborn Stars Glow Pink In Infrared Light, and Clouds of Gas and Dust, Resambling Puffy Cumulus Clouds, Are Dotted With With Dark KNOTS of DENSER DUST.
This image shows an infrared view from hubble, giving an excellent view of the stars that might otherwise be obscured by sh2-284's clouds. Unlike Visible Light, Infrared Wavelengths Can Travel Through Clouds of Gas and Dust, Providing a glimpse of the stars forming with the obscurning clouds.
The nebula is shaped by a young center star cluster, dolidze 25 (not visible in the hubble image), whose stars Range from 1.5 to 13 Million Years Old (OR Suun, In Contrast, IS 4.6 billion res. The cluster blasts out ionizing winds and radiation, pushing at the gas and dust of the nebula and carving out intricate shapes and pillars, as seen in detail here. This ionizing radiation gives sh2-284 its classification as an Hii region, an emission nebula consisting primarily of ionized hydrogen. An emission nebula like sh2-284 glows with its light as stars within or nearby energy
SH2-284 is also a low-metallicity region, which means it is poor in elements heavier than hydrogen and helium. These conditions mimic the early universe, when matter was mostly helium and hydrogen and heavier elements was just beginning to form via via nuclear fusion with stars. Hubble Took these images as part of an effort to examine how low metallicity influencestellar formation and how this would apply to the early universe.
SH2-284 Residences 15,000 light-Years ave at the end of an Outer Spiral Arm of our Milky Way Galaxy, In the Constellation Monoceros.
