Telescopes Team Up for New View of Cat’s Eye Nebula – In Euclid’s wide, near-infrared, and visible light view, the arcs and filaments of the nebula’s bright central region are situated within a halo of colorful fragments of gas zooming away from the star. This ring was ejected from the star at an earlier stage, before the main nebula at the center formed. Hubble captures the very core of the billowing gas with high-resolution visible-light images, adding extra detail in the center of this image. The whole nebula stands out against a backdrop teeming with distant galaxies, demonstrating how local astrophysical beauty and the farthest reaches of the cosmos can be seen together in modern astronomical surveys. Together, these missions provide a rich and complementary view of NGC 6543 — revealing the delicate interplay between stellar end-of-life processes and the vast cosmic tapestry beyond.

Picture of the day Famous sanctuary of the temple of Ramses II, Abu Simbel, Egypt. The Great Temple at Abu Simbel, which took about twenty years to build, was completed around year 24 of the reign of Ramesses the Great (which corresponds to 1265 BC). It was dedicated to the gods Amun, Ra-Horakhty, and Ptah, as well as to the deified Ramesses himself. It is generally considered the grandest and most beautiful of the temples commissioned during the reign of Ramesses II, and one of the most beautiful in Egypt. In the sanctuary are rock cut sculptures of four seated figures: Ra-Horakhty, the deified king Ramesses, and the gods Amun Ra and Ptah, the main divinities in that period. It is believed that the axis of the temple was positioned by the ancient Egyptian architects in such a way that on October 22 and February 22 (allegedly the king’s birthday and coronation day, respectively), the rays of the sun would penetrate the sanctuary and illuminate the sculptures on the back wall, except for the statue of Ptah, a god connected with the realm of the dead, who always remained in the dark. People gather at Abu Simbel on these days to witness this. #ImageOfTheDay
