>After more than three decades of operation, NASA’s Hubble Space Telescope continues to deliver groundbreaking insights into teh cosmos, and its latest findings are no exception. Released this week, a series of newly processed images showcase protoplanetary disks-the swirling nurseries where stars and planets are born-offering astronomers unprecedented views of stellar evolution.These observations, a collaborative effort between NASA and the European Space Agency (ESA), highlight the telescope’s enduring value in expanding our understanding of the universe and the potential for planetary systems beyond our own.
WASHINGTON – NASA’s Hubble Space Telescope has captured a stunning collection of images revealing protoplanetary disks – swirling structures of gas and dust considered the birthplaces of new stars and planets. The observations, released on Monday, January 19, 2026, offer scientists a deeper understanding of how stars and planetary systems evolve throughout the universe. Understanding these processes is crucial for comprehending our own solar system’s origins and the potential for life elsewhere.
The released images showcase disks surrounding several stars in various stages of formation. Some images utilize visible light, while others employ infrared light, providing a comprehensive view of the different phases of stellar development.

What are Protoplanetary Disks?
As a star begins to form, it draws in surrounding gas and dust. This material coalesces into a rotating disk known as a protoplanetary disk. The gas and dust within these disks feed the growing star, while the remaining orbiting material has the potential to eventually form planets.
In visible light images, protoplanetary disks appear as dark silhouettes against the bright glow of surrounding nebulas – regions of gas and dust illuminated by starlight. Jets of gas emanating from the forming stars are also visible in some of the images.
One observed object, HH 390, is viewed edge-on, revealing its disk as a thin line of darkness. Both HH 390 and Tau 042021 are located approximately 450 light-years from Earth within the Taurus Molecular Cloud. Stars in the lower portion of the visible light images are situated nearly 500 light-years away in the Chameleon I star-forming region.
The Role of Infrared Light in Observations
Images captured using infrared light reveal stars at earlier stages of evolution than those visible in the visible light spectrum. These young stars are often shrouded in thick layers of dust. Infrared light, unlike visible light, can penetrate these dust clouds, offering a clearer view of the developing star and its surrounding disk.
In the infrared images, the dark areas at the center of the bright glow represent the protoplanetary disks. Shadows cast by the disks onto surrounding clouds make them appear larger than their actual size. Stars in the upper right and lower left of the infrared images are located within the Orion Molecular Cloud, approximately 1,300 light-years away. Stars in the upper left and lower right are found in the Perseus Molecular Cloud, about 1,500 light-years from Earth.
This collection of images, compiled from data provided by NASA and ESA, is the result of collaboration between a team of scientists including K. Stapelfeldt from the Jet Propulsion Laboratory and T. Megeath from the University of Toledo, with processing completed by Gladys Kober of NASA/Catholic University of America. These findings represent a significant step forward in unraveling the mysteries of star and planet formation within our galaxy.
