    NASA’s James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star.

    These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb’s Near-Infrared Camera (NIRCam).

    The protostar itself is hidden from view within the “neck” of this hourglass shape. An edge-on protoplanetary disk is seen as a dark line across the middle of the neck.

    Light from the protostar leaks above and below this disk, illuminating cavities within the surrounding gas and dust.

    This protostar is a hot, puffy clump of gas that’s only a fraction of the mass of our Sun.

    As it draws material in, its core will compress, get hotter, and eventually begin nuclear fusion — creating a star!

    See that dark line at the very center of the “hourglass”?

    That’s an edge-on view of a protoplanetary disk, or the disk of material being pulled into the star as it forms.

    It’s about the size of our solar system and may eventually clump into planets, giving us a window into our solar system’s history.
