Webb Telescope Snaps a Cosmic Fireworks Show — Made of Baby Stars!
Quick Summary
NASA’s James Webb Space Telescope just released a stunning new photo of baby stars putting on their own fireworks show — just in time for the Fourth of July! The image shows newborn stars shooting colorful jets of gas and dust out into space. Scientists say the picture is helping us understand how stars like our own Sun are born.
What Happened?
On July 2, 2026, NASA released a brand-new image from the James Webb Space Telescope (JWST) showing a region of space called FS Tau, located about 450 light-years away in the constellation Taurus — the Bull.
NASA’s James Webb Space Telescope captured the infrared light of numerous features that previously were impossible to see beyond the thick dust of the FS Tau star system. In addition to many background galaxies that burst into view like fireworks, the image flickers with a number of protostars — baby stars formed from dense pockets of gas and dust.
The protostars of FS Tau are about 1 to 3 million years old, which is relatively young on cosmic scales. Our Sun, by contrast, is 4.6 billion years old.
So what makes the photo look like fireworks? As these baby stars grow, they shoot out powerful streams of material into space. These outflows, seen as orange and red wisps and wide sheets, are thought to come from the protostar FS Tau B. As FS Tau B feeds on the surrounding dust and gas to grow, it ejects some of that matter outward.
The effect of these outflows can be seen through prominent blue ridges — dense regions of gas that reflect light from the nearby protostars — making the whole scene look like a dazzling celestial light show.
Before Webb, much of this spectacular action was hidden. Hubble’s visible-light view showed the star-forming region mostly obscured by thick dust. Webb sees through the dust, revealing how the protostars are shaping their surroundings.
Why Does It Matter?
Every star in the night sky — including our Sun — was once a tiny protostar just like the ones in this picture. By studying FS Tau, scientists can piece together the story of how stars are born and how they grow. The JWST image of FS Tau also reveals gaps between the outflows, supporting the theory that protostars gather material in discrete episodes and lie dormant in between — almost like a star taking a big gulp, then resting, then gulping again! The better we understand baby stars, the better we understand the origins of our entire solar system.
Big Words
- Protostar — A very young star still in the process of forming; it hasn’t started nuclear fusion yet
- Infrared light — A type of light that humans can’t see with our eyes, but telescopes like Webb can detect; it passes right through dust clouds
- Outflow — Streams of gas and dust that a baby star shoots out into space as it grows
- Constellation — A pattern of stars in the sky that forms a recognizable shape and has been given a name
- Molecular cloud — A giant, cold cloud of gas and dust in space where new stars are born
Fun Fact
The FS Tau star system is so close (in space terms!) that if you could travel at the speed of light, you’d arrive there in only 450 years — about the same time that has passed since European explorers first landed in the Americas!
Think About It
If our Sun was once a tiny, noisy baby star just like FS Tau B — shooting out jets of gas and shaping the space around it — what do you think the early solar system looked like before Earth existed?
