A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at the massive star-forming nebula G035.20-0.74.

G035.20-0.74 is located approximately 2,190 parsecs (7,143 light-years) away in the constellation of Aquila.

Also known as IRAS 18556+0136, this high-mass star-forming region is home to a massive protostar with a jet driven outflow.

“Stars are born from turbulent clouds of gas and dust that collapse under their own gravitational attraction,” the Hubble astronomers explained.

“As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating a protostar.”

“G035.20-0.74 is known for producing a particular kind of massive star known as a B-type star,” they added.

“These stars are hot, young, blue stars up to five times hotter than our Sun.”

Hubble observed G035.20-0.74 as part of a program examining jets of blasted into space by massive protostars.

“These fast-moving jets, which form as gas collects around newly forming stars and last for only about 100,000 years, are known to play a role in star formation,” the researchers said.

“We were interested to learn whether such jets influence the formation of massive stars similar to the way they affect the formation of lower-mass stars.”

“Massive stars are typically rarer, more distant, and more hidden by dust than lower-mass stars, making studies of their jets more challenging.”

The scientists combined infrared observations from Hubble with those from radio telescopes in order to see inside these dusty star-forming regions.

“We found a jet of material with properties similar to jets associated with young, low-mass stars,” they said.

“This implies that the mechanism creating the light emitted by these jets is similar in young stars of different masses, up to 10 times the mass of the Sun.”
