The Hubble Space Telescope captured a laser-like jet that represents a “tantrum” being thrown by an infant star.
The outburst came from a very young star just starting its evolution, and the image shows a jet of gas traveling supersonically. The glow you see in the image comes from the jet colliding with gas and dust around the star, officials at the European Space Agency (ESA) wrote in an image description on Monday (March 7).
“The result,” the officials added, “is the colorfully wispy structures, which astronomers refer to as Herbig–Haro objects, billowing across the lower left of this image.” (Herbig-Haro objects are bright patches of gas, or nebulosity, near newborn stars.)
HH34 is about 1,250 light-years from Earth and resides in the famous Orion Nebula, which Hubble has also imaged many times over the decades. Orion is noted for its starbirth regions, and Hubble has an advantage in looking at the nebula; it’s the closest stellar nursery to Earth.
ESA added that the new imagery will be helpful for potential future science with the recently launched James Webb Space Telescope, which is in a commissioning period until about June.
“Webb — which will observe at predominantly infrared wavelength — will be able to peer into the dusty envelopes surrounding still-forming protostars, revolutionizing the study of jets from these young stars,” ESA officials wrote. “Hubble’s high-resolution images of HH34, and other jets, will help astronomers interpret future observations with Webb.”
