This JWST Picture of the Month features IRAS 04302+2247, a planet-forming disc located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation. Image Credit:

The so-called Butterfly star gets its name from its edge-on appearance. The star's protoplanetary disk blocks out starlight revealing a nebula, or butterfly wing, on each side. Deeper JWST observations show the disk is tilted and asymmetrical, which affects how planets form.
