From today's featured article
The tufted jay, also known as the painted jay and Dickey's jay, is a species of bird in the crow family, Corvidae. It is endemic to a small area of the Sierra Madre Occidental in Mexico. A large jay, it has a prominent dark crest on its head; a purplish-blue back, wings, and face; a white spot above the eye and on the cheek; white undersides; and a partially white tail. Its typical call is a quick, four-note vocalization. The relationship between the tufted jay and other members of the genus Cyanocorax has been a subject of interest since the species was first described in 1935. Because of the visual similarities between the tufted jay and the white-tailed jay, the two were thought by some to be closely related. A 2010 mitochondrial-DNA study has shown that the tufted jay is most closely related to a group of South American jays, despite their ranges being separated by more than 2,000 km (1,200 mi). They are likely descended from an ancestral jay that ranged throughout Latin America. (Full article...)

The Vela supernova remnant, in the southern constellation Vela, is one of the closest known supernova remnants to Earth, being around 800 light-years away. Its source Type II supernova exploded approximately 11,000 years ago. The association of the Vela supernova remnant with the Vela Pulsar was made by astronomers at the University of Sydney in 1968; this, along with the Crab Pulsar, was among the first direct observational evidence that supernovae form neutron stars. This astrophotograph of the Vela supernova remnant was taken by the European Southern Observatory's VLT Survey Telescope at the Paranal Observatory in Chile in 2022. The image has a field of view of 84 arcminutes and was produced as a mosaic of observations with four filters, here represented by the colours magenta, blue, green and red. The supernova remnant appears as wisps of pink and orange clouds, with stars in blue and yellow scattered throughout. Photograph credit: European Southern Observatory / TIMER survey
