2MASS J17554042 6551277

Explanation: 2MASS J17554042+6551277 doesn't exactly roll off the tongue but that's the name, a coordinate-based catalog designation, of the star centered in this sharp field of view. Fans of the distant universe should get used to its spiky appearance though. The diffraction pattern is created by the 18 hexagonal mirror segments of the James Webb Space Telescope. After unfolding, the segments have now been adjusted to achieve a diffraction limited alignment at infrared wavelengths while operating in concert as a single 6.5 meter diameter primary mirror. The resulting image taken by Webb's NIRcam demonstrates their precise alignment is the best physics will allow. 2MASS J17554042+6551277 is about 2,000 light-years away and well within our own galaxy. But the galaxies scattered across the background of the Webb telescope alignment evaluation image are likely billions of light-years distant, far beyond the Milky Way.

What is that at the end of the road? The sun. On two days each year, the sun sets down in the middle of the road that runs east - west. Today is an equinox. Not only is today a day of equal night and day time, but also a day when the sun rises to the east and sets to the west. There is a road in northwest Illinois that runs east to west. The Sun can be seen down the road at sunset in the image. The first day of a season in many cultures is the March equinox, which is the first day of spring in the north and autumn in the south. Does your street go east or west? You can find out at sunset.
