Dramatic bursts from a newborn star, known as Herbig-Haro 49/50 (HH 49/50), have been captured by NASA’s James webb Space Telescope (JWST), creating a striking cosmic scene.
Herbig-Haro objects are collections of gas and dust clouds formed by newborn stars, or protostars. These objects form when jets of charged particles, ejected from a young star at high speeds, collide with surrounding material, producing a luminous pattern.
Located in the Chamaeleon I cloud complex, Herbig-Haro 49/50 showcases the chaotic beauty of star formation. The Chamaeleon I cloud complex is one of the star-forming regions closest to the Milky Way Galaxy and is known for producing low-mass stars similar to our sun. The cloud complex is believed to resemble the habitat in which our sun formed.
First observed in 2006 by the Spitzer Space Telescope,previous observations revealed that HH 49/50 sprays material away from Earth at speeds of 100 to 300 kilometers per second. Scientists estimate that the source of these bursts is a protostar known as Cederblad 110 IRS4 (CED 110 IRS4), located approximately 1.5 light-years from the cosmic tornado-like object.
CED 110 IRS4 is considered very young by cosmic standards, only tens of thousands to millions of years old, and is still growing by absorbing material from the surrounding disc. During this process,some gases are ejected along the magnetic field lines of the young star as high-speed jets. These jets then collide with the surrounding gas and dust clouds, creating the Herbig-Haro object. The shining shock waves mark the points where the bursts collide with the surrounding material.
HH 49/50 is a result of one of these collisions. It has been nicknamed the ‘Cosmic Tornado’ due to its twisted shape. While images from the Spitzer telescope were not clear, the James Webb Telescope, using its Near-Infrared Camera (NIRCam) and mid-Infrared Instrument (MIRI), captured images of glowing hydrogen molecules and carbon monoxide, appearing in orange and red, heated and energized by the powerful jets.
Detailed images from the James Webb Telescope of HH 49/50 revealed a gas trail that helps astronomers trace the jet’s path back to its origin,CED 110 IRS4.
Webb has recorded these two separate objects in a compatible luck. For thousands of years, the edge of HH 49/50 will move as part of the bursts and will reach a distant galaxy.james Webb team

What is Herbig-Haro 49/50?
herbig-Haro 49/50 (HH 49/50) is a fascinating celestial object: a spectacular collection of gas and dust clouds created by the powerful jets emanating from a newborn star, or protostar.These objects are formed when high-speed jets of charged particles ejected from a young star collide with the surrounding interstellar material, creating a luminous display. The James Webb Space Telescope (JWST) has captured incredibly detailed images of HH 49/50, offering unprecedented insights into the processes of star formation.
Where is HH 49/50 Located?
HH 49/50 is located within the Chamaeleon I cloud complex,a region known for active star formation and one of the closest star-forming regions too our Milky Way Galaxy. This cloud complex is believed to closely resemble the environment in which our own Sun formed, making it a valuable area for studying solar system origins.
What Does HH 49/50 Look Like?
The images from the James Webb Space Telescope show HH 49/50 in stunning detail, revealing the intricate structures within the outflow. The JWST’s Near-Infrared Camera (NIRCam) and mid-Infrared Instrument (MIRI) capture the glowing hydrogen molecules and carbon monoxide in the region, with colors represented in reddish-orange hues. The “cosmic Tornado” nickname comes from its twisted and complex structure.
How Was HH 49/50 Observed?
The James Webb Telescope observed HH 49/50 using two primary instruments:
NIRCam (Near-Infrared Camera): Captures images in the near-infrared light spectrum.
MIRI (Mid-Infrared Instrument): Provides data in the mid-infrared light spectrum.
These instruments allowed astronomers to observe the outflow with remarkable clarity,revealing details that were not visible in previous observations.
What Are the Jets?
The jets are streams of charged particles ejected from the protostar at high speeds. These jets are created by the protostar absorbing materials from its surrounding disc, which causes some gases to be ejected along the magnetic field lines of the young star.
What Causes the “Cosmic Tornado” Appearance?
The ‘Cosmic Tornado’ appearance of HH 49/50 is a result of the interaction between the jets from the protostar and the surrounding gas and dust clouds. As the high-speed jets collide with the surrounding material, they generate shock waves. The twisted shape of HH 49/50 is the result of the jets.
How Fast Do the Jets Travel?
Previous observations, recorded by the Spitzer Space Telescope, revealed that material is being dispersed from HH 49/50 at speeds ranging between 100 to 300 kilometers per second.
What is the Protostar?
The source of the bursts in HH 49/50 is identified as a protostar known as Cederblad 110 IRS4 (CED 110 IRS4). This protostar is considered very young in cosmic terms,only tens of thousands to millions of years old.
Why is Studying HH 49/50 Crucial?
Studying HH 49/50 provides essential insights into:
Star Formation: Understanding how young stars and protostars generate jets and how they interact with their surroundings.
environment Influence: How the activity of young stars affects the environment around them.
* Solar System Formation: The Chamaeleon I cloud complex is similar to the environment in which our sun would have formed.
