Hubble Dwelling Telescope Observes Prawn Nebula

The Hubble team has released a striking say captured by the NASA/ESA Hubble Dwelling Telescope exhibiting a runt share of the Prawn Nebula (IC 4628).

The Prawn Nebula is a extensive stellar nursery positioned roughly 6,000 light-years away within the constellation of Scorpius.

Astronomers classify it as an emission nebula, which manner its gasoline has been energized, or ionized, by the radiation of internal reach stars.

“The radiation from these huge stars strips electrons from the nebula’s hydrogen atoms,” the Hubble astronomers said.

“Because the energized electrons revert from their increased-vitality tell to a decrease-vitality tell by recombining with hydrogen nuclei, they emit vitality within the create of light, causing the nebula’s gasoline to glow.”

“On this Hubble say, red indicates the presence of ionized iron (Fe II) emission.”

The Prawn Nebula is furthermore identified as Gum 56, after the Australian astronomer Colin Gum, who printed a catalogue of HII regions in 1955.

“Though the nebula stretches 250 light-years and covers a house four situations the scale of the beefy moon, it emits light basically in wavelengths the human seek can not detect, making it extraordinarily faint to earthbound viewers,” the researchers said.

“Hubble’s examine, on the opposite hand, reveals a runt share of the nebula here in both visible and invisible infrared light, taking pictures ultimate-making an strive factor of the nebula’s structure, alongside side intellectual areas of pleasing gasoline.”

“This say turned into once captured as share of a examine of large- and intermediate-dimension protostars,” they added.

“We feeble the infrared sensitivity of Hubble’s Extensive Self-discipline Digicam 3 (WFC3) to seem at for hydrogen ionized by ultraviolet light ionized by the protostars, jets from the stars, and other parts.”
