NASA Astronomy Picture of the Day:

Why are there so many bright blue stars? Stars are usually born in clusters, and the brightest and most massive of these stars typically glow blue. Less-bright, non-blue stars like our Sun surely also exist in this M41 star cluster but are harder to see. A few bright orange-appearing red giant stars are visible. The red-light filaments are emitted by diffuse hydrogen gas, a color that was specifically filtered and enhanced in this image. In a hundred million years or so, the bright blue stars will have exploded in supernovas and disappeared, while the slightly different trajectories of the fainter stars will cause this picturesque open cluster to disperse. Similarly, billions of years ago, our own Sun was likely born into a star cluster like M41, but it has long since drifted apart from its sister stars. The featured image was captured over four hours with Chilescope T2 in Chile.

NASA Astronomy Picture of the Day:

Can a lava flow extend into the sky? No, but light from the lava flow can. One effect is something quite unusual -- a volcanic light pillar. More typically, light pillars are caused by sunlight and so appear as a bright column that extends upward above a rising or setting Sun. Alternatively, other light pillars -- some quite colorful -- have been recorded above street and house lights. This light pillar, though, was illuminated by the red light emitted by the glowing magma of an erupting volcano. The volcano is Italy's Mount Etna, and the featured image was captured with a single shot during an early morning in mid-February. Freezing temperatures above the volcano's lava flow created ice-crystals either in the air above the volcano or in condensed water vapor expelled by Mount Etna. These ice crystals -- mostly flat toward the ground but fluttering -- then reflected away light from the volcano's caldera.

The Kaohsiung Music Center and the Lingyaliao Railroad Bridge illuminated in the colors of Ukraine's national flag during the 2022 Taiwan Lantern Festival. This light show was displayed from February 26, two days after Russia's invasion of Ukraine.

During its first month, the second Trump administration has pushed a new balance of these powers, granting the president expansive and far-reaching authority. These actions imperil the power of elected lawmakers in the House and Senate to pass legislation, oversee the federal government and exercise spending authority. More at The Conversation ➜

Gilbert Keith Chesterton (1874 –1936) was an English writer,[philosopher, Christian apologist, and literary and art critic. He has been referred to as the "prince of paradox" Chesterton created the fictional priest-detective Father Brown,] and wrote on apologetics. Even some of those who disagree with him have recognized the wide appeal of such works as Orthodoxy and The Everlasting Man. Chesterton routinely referred to himself as an "orthodox" Christian, and eventually converted to Roman Catholicism from high church Anglicanism.

NASA Astronomy Picture of the Day:

Saturn looks slightly different in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn's North Pole. Each side of the dark hexagon spans roughly the width of our Earth. The hexagon's existence was not predicted, and its origin and likely stability remain a topics of research. Saturn's famous rings circle the planet and cast shadows below the equator. The featured image was taken by the robotic Cassini spacecraft in 2014 in several infrared colors. In 2017 September, the Cassini mission was brought to a dramatic conclusion when the spacecraft was directed to dive into the ringed giant.
