James Webb Telescope spots cosmic hourglass filled with new stars


Astronomers used Webb’s Near-Infrared Camera (NIRCam) to observe the protostar, which is hidden from view and is a way for astronomers to study our Sun.

In Short

  • James Webb Telescope is located 15,00,000 kilometers away from Earth
  • Astronomers used Webb’s Near-Infrared Camera (NIRCam) to observe protostar
  • The dark cloud L1527 is just 1,00,000 years old

By India Today Web Desk: Hanging in the vacuum of space about 15,00,000 kilometers away from Earth, the James Webb Space Telescope (JWST) has looked at the protostar within the dark cloud L1527 unraveling secrets of new stars. The observatory peeked into clouds within the Taurus star-forming region in infrared light.

Astronomers used Webb’s Near-Infrared Camera (NIRCam) to observe the protostar, which is hidden from view within the “neck” of the hourglass shape. The image shows a dark line across the middle of the neck as light from the protostar leaks above and below this disk, illuminating cavities within the surrounding gas and dust.


Nasa releasing the image said that the clouds, coloured blue and orange, outline cavities created as material shoots away from the protostar and collides with surrounding matter. The colors themselves are due to layers of dust between Webb and the clouds. The thicker the layer of dust, the less blue light is able to escape, creating pockets of orange.

Ejections from the star have cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. The upper central region displays bubble-like shapes due to stellar “burps,” or sporadic ejections. (Photo: Nasa)

“Webb also reveals filaments of molecular hydrogen that have been shocked as the protostar ejects material away from it. Shocks and turbulence inhibit the formation of new stars, which would otherwise form all throughout the cloud. As a result, the protostar dominates the space, taking much of the material for itself,” Nasa said.
