A new image taken with the NASA/ESA Hubble Space Telescope show HH46 and HH47, two Herbig-Haro objects — small-scale shock regions associated with newborn stars — located 1,400 light-years away in the constellation of Vela.

Herbig-Haro objects are transient phenomena — traveling away from the star that created them, at a speed of up to 250,000 kmh (155,000 mph) they disappear into nothingness within a few tens of thousands of years.

They come in a wide array of shapes, the basic configuration is usually the same. Twin jets of heated gas, ejected in opposite directions from a forming star, stream through interstellar space.

These outflows are fueled by gas falling onto the young star, which is surrounded by a disk of dust and gas.

Image credit: NASA / ESA / Hubble / B. Nisini.

This Hubble image shows two Herbig-Haro objects HH46 and HH47. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).

It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter

This video shows the evolution over time of Herbig-Haro object HH 47, a jet expelled from a newborn star in the southern constellation of Vela.
