Resembling an interstellar Frisbee, the dark feature in these two Hubble images is a protoplanetary disk of dust seen edge-on around a newborn star in M42. The two images show the disk through two different sets of filters: one to probe the disk’s chemical composition (left) and another to reduce the brightness of the nebula, revealing brighter regions above and below the disk that betray the presence of the star (right). Because the disk is edge-on, its star is largely hidden, but the disk may be an embryonic planetary system in the making. Our solar system probably formed out of such a disk 4.5 billion years ago.

Appearing like glistening precious stones, M42’s Trapezium cluster, named for the trapezoidal arrangement of its central massive stars, is seen in this infrared Hubble image. All of the members of the Trapezium were born together in this hotbed of star formation. CREDIT K.L. Luhman (Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass.); and G. Schneider, E.

This stunning Hubble image offers the sharpest view of the Orion Nebula ever obtained. Created using 520 different Hubble exposures taken in multiple wavelengths of light, this mosaic contains over one billion pixels. Hubble imaged most of the nebula, but ground-based images were used to fill in the gaps in its observations. The orange color in the image can be attributed to hydrogen, green represents oxygen, and the red represents both sulfur and observations made in infrared light. Credit NASA, ESA, M.

Probing deep within a neighborhood stellar nursery, NASA's Hubble Space Telescope uncovered a swarm of newborn brown dwarfs. The orbiting observatory's near-infrared camera revealed about 50 of these objects throughout the Orion Nebula's Trapezium cluster [image at right], about 1,500 light-years from Earth. Appearing like glistening precious stones surrounding a setting of sparkling diamonds, more than 300 fledgling stars and brown dwarfs surround the brightest, most massive stars [center of picture] in Hubble's view of the Trapezium cluster's central region. The brown dwarfs are too dim to be seen in an image taken by the Hubble telescope's visible-light camera [picture at left]. [...] The near-infrared image was taken Jan. 17, 1998. Two near-infrared filters were used to obtain information on the colors of the stars at two wavelengths (1.1 and 1.6 microns). The Trapezium picture is 1 light-year across. This composite image was made from a "mosaic" of nine separate, but adjoining images. In this false-color image, blue corresponds to warmer, more massive stars, and red to cooler, less massive stars and brown dwarfs, and stars that are heavily obscured by dust. The visible-light data were taken in 1994 and 1995. Credit * Near-infrared image: NASA; K.L. Luhman and G. Schneider, E. Young, G. Rieke, A. Cotera, H. Chen, M. Rieke, R.

1. Bsky post by ESA Operations ‪@operations.esa.int‬ Flyby success! ESA's Juice spacecraft passed Venus at 07:28 CEST on 31 August. This photo shows our deep-space antenna in Spain in communication with Juice during the flyby. Juice’s current location, Venus, and its destination, Jupiter, are both visible in the sky ❤️ 2. Bsky post by ESA Operations ‪@operations.esa.int‬ Congratulations to the Juice operations team at ESA mission control in Germany for the smooth gravity assist that helped Juice pick up the speed required to get to Jupiter. 👏 Juice’s next planetary flyby will be at Earth in September 2026. On, on, onwards, up the gravity well!
