Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking infrared image of a protostar called J1672835.29-763111.64 (J1672 for short).

The J1672 protostar resides in IC 2631, a reflection nebula located some 500 light-years away in the southern constellation of Chamaeleon.

These objects are part of the Chamaeleon Complex, a large region of gas and dust clouds that harbors numerous newborn and still-forming stars.

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

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

“Protostars shine with the heat energy released by clouds contracting around them and the accumulation of material from the nearby gas and dust,” they added.

“Eventually enough material collects, and the core of a protostar becomes hot and dense enough for nuclear fusion to begin, and the transformation into a star is complete.”

“The leftover gas and dust can become planets, asteroids, comets, or remain as dust.”

The new Hubble image of J1672 is part of a Hubble survey targeting 312 protostars within molecular clouds previously identified with NASA’s Spitzer Space Telescope and ESA’s Herschel Space Observatory.

“Protostars are visible primarily in infrared light since they emit a lot of heat energy, and their visible light is obscured by the dust around them,” the researchers noted.

“Hubble’s advanced infrared capabilities could better resolve the protostars and examine their structure, including the accumulating gas and dust and faint companion objects.”
