Webb reveals stars of different ages in a dusty nebula

NASA says infrared light let Webb peer through the nebula’s dust, helping scientists study how stars change over time.

5 Sources, 11d ago, updated 11d ago

$A young star cluster filled with many stars that display Webb’s unique eight-pronged diffraction pattern. At its center is a yellow star which sports the largest diffraction pattern. To the left of the star, there is a region filled with yellow dust and gas. This yellow region extends from the bottom, covering about two-thirds of the image. The yellow region has several blue stars of different sizes embedded within. The top third, which lies outside of the yellow region, holds a few bright protostars, within dense gray gas. Those stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust.$

JUICE completed an Earth gravity assist on its way to Jupiter

ESA Science said JUICE used Earth’s gravity to shift its path by 20 degrees and add 3.5 km/s of speed, while ESA Operations said the spacecraft reacquired signal at 15:01 CEST after a planned eclipse through Earth’s shadow.
