The newest space telescope on the block has spotted a blazing cosmic hourglass filled with vibrant colors and hiding a fledgling star, or protostar, at its heart.-forming region and the protostar within it has been hidden to telescopes by a dense, dark cloud of gas and dust known as L1527.
The protostar within L1527 and the cause of these turbulent conditions is only 100,000 years old, a mere infant in cosmic terms. Its young age and infrared brightness make the L1527 star what astronomers call a class 0 protostar, which marks the earliest stage of star formation. Class 0 protostars like this one are still cocooned within the clouds of gas and dust from which they form, and are still some way away from becoming full stars.
Currently, the protostar's shape is predominantly spherical but still unstable, and would look like a small, hot and"puffy" clump of gas with a mass between 40% and 20% of theWhile the protostar is hidden, the image reveals a protoplanetary disk of gas and dust around the star, which appears as a dark line across the neck of the hourglass.
A James Webb Space Telescope image of the protostar at the heart L1527 shows the turbulent cosmic hourglass shape it creates.Even as much of the surrounding material is being fed to the protostar, allowing it to gather mass, the JWST image also shows filaments of molecular hydrogen that have been shocked by material blasted out by the central protostar.
