When you look to the stars, you would possibly anticipate to see a planet, a star, and even the International Space Station, however this week’s Hubble picture exhibits one thing reasonably surprising: A Prawn. The picture exhibits the stunning Prawn Nebula, positioned round 6,000 light-years away in the tail portion of the constellation Scorpius.
Despite the nebula’s giant measurement, spanning over 250 light-years, it’s hardly ever imaged as it is extremely dim, emitting solely a small quantity of mild. The stars which may be seen look like a blue-white coloration, however along with this most of the stars inside the nebula emit mild in different parts of the spectrum which can be invisible to the human eye. Hubble photos in each the seen mild wavelength and the infrared, permitting it to see extra particulars of the stunning swirls of mud and fuel.
“The Prawn Nebula, also known as IC 4628, is an emission nebula, which means its gas has been energized, or ionized, by the radiation of nearby stars,” Hubble scientists explain. “The radiation from these massive stars strips electrons from the nebula’s hydrogen atoms. As the energized electrons revert from their higher-energy state to a lower-energy state by recombining with hydrogen nuclei, they emit energy in the form of light, causing the nebula’s gas to glow. In this image, red indicates the presence of ionized iron (Fe II) emission.”
The nebula is a busy star-forming area, creating each particular person stars and clusters of stars. In between these factors of mild are voids or cavities, that are created when scorching stars give off stellar winds which blow away matter like mud and fuel.
To present the nebula in its full context, the Hubble scientists additionally launched this picture of the full nebula, displaying the place this explicit zoom-in picture suits into the complete:
