The space observatory’s latest target is one of the youngest known protostellar outflows.
The Webb Space Telescope’s latest subject—bipolar jets of material that stretch out in the inky black like the mantle of an iridescent squid—provoke that exact reaction.The jets are collectively known as Herbig-Haro 211. They shoot outwards in opposite directions from a young star that sits about 1,000 light-years from Earth in the constellation Perseus. The protostar—not visible in the image—is only about 8% the mass of our Sun.
, are composed of silicon monoxide. The parts of the outflow nearest to the protostar are traveling between 48 to 60 miles per second .Webb’s remarkable resolution at infrared and near-infrared wavelengths makes Herbig-Haro 211 much clearer to see through the gas and dust that surrounds it and obscures it to other telescopes. But the object still holds secrets; for one, the unresolved protostar at its core may actually be a binary star.

Webb confirms accuracy of universe's expansion rate, deepens mystery of Hubble constant tensionThe rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However, a persistent difference called the 'Hubble Tension' is seen between the value of the constant measured with a wide range of independent distance indicators and its value predicted from the big bang afterglow.
