A new picture from the James Webb Space Telescope shows stars being born. NASA released the image of NGC 7129, a stellar nursery about 3,300 light-years from Earth. Space.com notes it is nicknamed the Flower Bud Nebula.

Young stars are hard to see. They form inside cold, dense clouds of gas and dust that block most light. Webb can see in infrared light, which passes through dust. That lets astronomers spot stars that were hidden before, NASA said.

The image was taken with Webb's Near-Infrared Camera, or NIRCam. In it, hot hydrogen gas glows gold. Cooler hydrogen gas, shocked by jets from forming stars, shows up in red. NASA calls the scene a "cauldron of cosmic creation."

The stars in this cluster are at different stages of life. The biggest stars form and change the fastest. The brightest star in the picture is LkHα 234. It has the image's most obvious spiky pattern. This young star weighs about 5 to 8 times as much as our Sun. It has mostly finished gathering mass and is now shrinking under its own gravity, which heats it up. In time, it will fuse hydrogen like the Sun does.

Next to it is a large gold cavity about 3.5 light-years across. It was carved by outflows from the central star earlier in its life, NASA said.

The nebula is thought to hold more than 100 stars younger than a million years old, Space.com reported. That is very young for a star.

Telescopes have studied this nebula before at other wavelengths. But Webb's sharp view gives scientists new detail on stars still forming. It may help them learn more about the powerful jets these stars shoot out and how the jets shape the gas around them.

Where to see it: The full image is on NASA's Webb mission pages and in Space.com's photo of the day for Oct. 7.

What we know: Webb revealed many hidden young stars and their jets in NGC 7129.
What we don't: How the jets will change the nursery as the stars grow.
