NASA Astronomy Picture of the Day:

Sometimes the dark dust of interstellar space has an angular elegance. Such is the case toward the far-south constellation of Chamaeleon. Normally too faint to see, dark dust is best known for blocking visible light from stars and galaxies behind it. In this 11.4-hour exposure, however, the dust is seen mostly in light of its own, with its strong red and near-infrared colors creating a brown hue. Contrastingly blue, a bright star Beta Chamaeleontis is visible on the upper right of the V, with the dust that surrounds it preferentially reflecting blue light from its primarily blue-white color. All of the pictured stars and dust occur in our own Milky Way Galaxy with one notable exception: a white spot just below Beta Chamaeleontis is the galaxy IC 3104, which lies far in the distance. Interstellar dust is mostly created in the cool atmospheres of giant stars and dispersed into space by stellar light, stellar winds, and stellar explosions such as supernovas.

NASA Astronomy Picture of the Day:

What has happened to Comet Lemmon's tail? The answer is blowing in the wind — the wind from the Sun in this case. This continuous outflow of charged particles from the Sun has been quite variable of late, as the Sun emits bursts of energy, CMEs, that push out and deflect charged particles emitted by the comet itself. The result is a blue hued ion tail for Comet C/2025 A6 (Lemmon) that is not only impressively intricate but takes some unusual turns. This long-duration composite image taken from Alfacar, Spain last month captured this inner Solar System ionic tumult. Comet Lemmon is now fading as it heads out away from the Earth and Sun and back into the outer Solar System.

Basilica, Xavier, Navarre, Spain. The basilica belongs to the ensemble of the Castle of Xavier, built in the 10th century, although the basilica was not built until end of the 19th and beginning of the 20th century. Of eclectic style, the interior has a unique neogothic nave built with grey stone and white marble. The stained glass is a work of painter Marcelino Santamaría from Burgos. The main altar is an artistic decorative work, carved in stone inlaid with mosaics, bronzes and enamels by the Biais house in Paris. The tabernacle is located on a high relief that represents San Francisco baptizing and preaching.
