Makemake and its moon
Makemake and its moon

Makemake is a dwarf planet orbiting the Sun beyond Neptune. It has a diameter 60% that of Pluto, and is the fourth-largest trans-Neptunian object and the largest member of the Solar System's classical Kuiper belt, a disk of icy bodies beyond Neptune's orbit. Its discovery on March 31, 2005, by American astronomers Mike Brown, Chad Trujillo and David Rabinowitz at Palomar Observatory contributed to the reclassification of Pluto as a dwarf planet in 2006. Makemake's surface, like Pluto's, is largely covered by frozen methane and stained reddish-brown by tholins. It has one known satellite, unnamed, whose orbit suggests that Makemake's rotation has a high axial tilt. Makemake shows evidence of geochemical activity and cryovolcanism, which has led scientists to suspect that it might harbor a subsurface ocean of liquid water. No high-resolution images of its surface exist because it has not been visited up close by a space probe. (This article is part of a featured topic: Solar System.)

Virgin and Child with Four Angels
Virgin and Child with Four Angels is a small oil painting on panel by the Early Netherlandish artist Gerard David, probably completed around 1510 to 1515. It shows the Virgin Mary holding the Christ Child, while two angels crown her as Queen of Heaven and two others play musical instruments at her sides. Set in a walled garden before a view of Bruges, the work was created for private devotion. It was influenced by Jan van Eyck's Virgin and Child at a Fountain, but presents Mary and Jesus in a more human manner rather than as remote iconic deities. The work has been in the collection of the Metropolitan Museum of Art in New York since 1977.Painting credit: Gerard David
