A collage of four images showing a dusty nebula. Two-thirds of the collage is taken up by a single image of the nebula, while the remaining third shows three insets stacked on top of each other. In the largest image at left, there is an orange and yellow fang-like cloud of matter that cuts the image in two. The left side of the fang shows more clouds of a dark brown shade, while the right shows filaments of light brown. There are a number of bright blue and red points of light spread throughout, three of which are circled in white and labeled with a number from one to three. Circle 1 is located at about 12 o’clock in the middle of the fang-like cloud, while Circle 2 is at about 5 o’clock and Circle 3 is located at about 7 o’clock, toward the bottom left of the image. Each circle magnifies an individual object, which is shown in each of the three squares to the right of the collage, labeled 1 to 3 from top to bottom. Each image contains a single, fuzzy point of light in the middle.

A collage of three near-infrared images showing a dusty nebula. The left two-thirds of the collage is taken up by a Hubble image of the nebula. The remaining third is taken up by two Webb images, one atop the other. The Hubble image has a pillar of dense brown dust running through the nebula at a diagonal from 5 o’clock to 11 o’clock. Wispy plumes appear to fly off from the pillar toward the sides amid blue clouds of the same material, which are whiter near the pillar. There are many white stars spread throughout. Two separate, white squares, tilted about 30 degrees, outline two areas in the pillar. The upper square has the letter “A” to the top right, while the lower square is marked by the letter “B”. These labels correspond to the two, magnified images of the nebula at right, with the top image also labeled “A” and the bottom image labeled “B”. Both images contain a mixture of reds, blues and browns, and show red, blue, and white stars.

In celebration of the 31st anniversary of the launch of the NASA/ESA Hubble Space Telescope, astronomers aimed the celebrated observatory at one of the brightest stars seen in our galaxy to capture its beauty. The giant star featured in this latest Hubble Space Telescope anniversary image is waging a tug-of-war between gravity and radiation to avoid self-destruction. The star, called AG Carinae, is surrounded by an expanding shell of gas and dust. The nebula is about five light-years wide, which equals the distance from here to our nearest star, Alpha Centauri.

JWST NIRCam color image of WFI2033-4723 (GTO Program #1198; PI: Stiavelli). The F115W band is mapped to the luminosity and blue, F150W to cyan, F277W to yellow, and the F356W band to red. Near the bottom image, there is a bright spot on the lower-right side that maps back to other bluer regions of the ring, indicating it is a multiply-imaged star-forming region (SFR) contained in the z∼1.6 host. Preliminary models place the physical size at ∼150pc located ∼2kpc from the center of the galaxy (assuming flat CDM cosmology with h = 0.7 and m = 0.3).

Previously unseen details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the 'Keyhole Nebula, ' obtained with the Hubble Space Telescope. The picture is a montage assembled from four different April 1999 telescope pointings with Hubble's Wide Field Planetary Camera 2, which used six different colour filters. The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel. This region, about 8000 light-years from Earth, is located adjacent to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right. The Carina Nebula also contains several other stars that are among the hottest and most massive known, each about 10 times as hot, and 100 times as massive, as our Sun.
