APOD: 2022-12-30 - Mars and the Star Clusters (Narrated by Brian)
Astronomy Picture of the Day - December 30th, 2022 - Mars and the Star Clusters (Narrated by Brian)
At this year's end Mars still shines brightly in planet Earth's night as it wanders through the head-strong constellation Taurus. Its bright yellowish hue dominates this starry field of view that includes Taurus' alpha star Aldebaran and the Hyades and Pleiades star clusters. While red giant Aldebaran appears to anchor the V-shape of the Hyades at the left of the frame, Aldebaran is not a member of the Hyades star cluster. The Hyades cluster is 151 light-years away making it the nearest established open star cluster, but Aldebaran lies at less than half that distance, along the same line-of-sight. At the right, some 400 light-years distant is the open star cluster cataloged as Messier 45, also known as the Pleiades or Seven Sisters. In Greek myth, the Pleiades were daughters of the astronomical titan Atlas and sea-nymph Pleione.
Beautiful News Daily - February 23rd, 2020 - Germany's Renewables Are Pushing Back Coal and Nuclear (Narrated by Matthew)
They call it energiewende: an energy revolution. Germany’s doing more than most to battle the climate crisis. It’s aiming for 65% renewable power by 2030. It’s already hit the 50% mark.

Astronomy Picture of the Day - April 5th, 2022 - Seven Sisters versus California (Narrated by Amy)
On the upper right, dressed in blue, is the Pleiades. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and most easily visible open clusters on the sky. The Pleiades contains over 3,000 stars, is about 400 light years away, and only 13 light years across. Surrounding the stars is a spectacular blue reflection nebula made of fine dust. A common legend is that one of the brighter stars faded since the cluster was named. On the lower left, shining in red, is the California Nebula. Named for its shape, the California Nebula is much dimmer and hence harder to see than the Pleiades. Also known as NGC 1499, this mass of red glowing hydrogen gas is about 1,500 light years away. Although about 25 full moons could fit between them, the featured wide angle, deep field image composite has captured them both. A careful inspection of the deep image will also reveal the star forming region IC 348 and the molecular cloud LBN 777 (the Baby Eagle Nebula).

Astronomy Picture of the Day - August 28th, 2020 - The Valley of Orion (Narrated by Brian)
This exciting and unfamiliar view of the Orion Nebula is a visualization based on astronomical data and movie rendering techniques. Up close and personal with a famous stellar nursery normally seen from 1,500 light-years away, the digitally modeled frame transitions from a visible light representation based on Hubble data on the left to infrared data from the Spitzer Space Telescope on the right. The perspective at the center looks along a valley over a light-year wide, in the wall of the region's giant molecular cloud. Orion's valley ends in a cavity carved by the energetic winds and radiation of the massive central stars of the Trapezium star cluster. The single frame is part of a multiwavelength, three-dimensional video that lets the viewer experience an immersive, three minute flight through the Great Nebula of Orion.

Beautiful News Daily - December 30th, 2019 - These Countries are Crushing it at Recycling (Narrated by Salli)
Germany has been the world’s best recycler since 2005. But now there’s a race for the top spot.
What gives all these countries the edge? Government funding. Landfill bans. Collection schemes. Incentives to encourage everyone to recycle. The result? Resources saved. Energy conserved. Environment protected.

Wikipedia Picture of the Day - April 24th, 2023 - Crested honey buzzard (Narrated by Brian)
The crested honey buzzard (Pernis ptilorhynchus), also known as the Oriental honey buzzard, is a bird of prey in the family Accipitridae. Its size ranges from 57 to 60 centimetres (22 to 24 in). The name is derived from its diet, which consists mainly of the larvae of bees and wasps, extracted from honeycombs. It has several adaptations for this diet, including an elongated head for foraging on underground nests and a groove in the tongue for feeding on honey. A mass of short, dense feathers on the head and neck protect against stinging attacks by social wasps. The crested honey buzzard is a year-round resident in Southeast Asia and the Indian subcontinent. Some birds migrate to Siberia and Japan during the summer for breeding. This crested honey buzzard was photographed in Mudumalai National Park, India.

Astronomy Picture of the Day - January 23rd, 2022 - Saturn, Tethys, Rings, and Shadows (Narrated by Brian)
Seen from ice moon Tethys, rings and shadows would display fantastic views of the Saturnian system. Haven't dropped in on Tethys lately? Then this gorgeous ringscape from the Cassini spacecraft will have to do for now. Caught in sunlight just below and left of picture center in 2005, Tethys itself is about 1,000 kilometers in diameter and orbits not quite five saturn-radii from the center of the gas giant planet. At that distance (around 300,000 kilometers) it is well outside Saturn's main bright rings, but Tethys is still one of five major moons that find themselves within the boundaries of the faint and tenuous outer E ring. Discovered in the 1980s, two very small moons Telesto and Calypso are locked in stable along Tethys' orbit. Telesto precedes and Calypso follows Tethys as the trio circles Saturn.

Astronomy Picture of the Day - August 4th, 2021 - EHT Resolves Central Jet from Black Hole in Cen A (Narrated by Salli)
How do supermassive black holes create powerful jets? To help find out, the Event Horizon Telescope (EHT) imaged the center of the nearby active galaxy Centaurus A. The cascade of featured inset images shows Cen A from it largest, taking up more sky than many moons, to its now finest, taking up only as much sky as an golf ball on the moon. The new image shows what may look like two jets -- but is actually two sides of a single jet. This newly discovered jet-edge brightening does not solve the jet-creation mystery, but does imply that the particle outflow is confined by a strong pressure -- possibly involving a magnetic field. The EHT is a coordination of radio telescopes from around the Earth -- from the Caltech Submillimeter Observatory in Hawaii USA, to ALMA in Chile, to NOEMA in France, and more. The EHT will continue to observe massive, nearby black holes and their energetic surroundings.

Astronomy Picture of the Day - July 2nd, 2020 - The Galaxy, the Planet, and the Apple Tree (Narrated by Joanna)
The Old Astronomer's Milky Way arcs through this peaceful northern sky. Against faint, diffuse starlight you can follow dark rifts of interstellar dust clouds stretching from the galaxy's core. They lead toward bright star Antares at the right, almost due south above the horizon. The brightest beacon in the twilight is Jupiter, though. From the camera's perspective it seems to hang from the limb of a tree framing the foreground, an apple tree of course. The serene maritime nightscape was recorded in tracked and untracked exposures on June 16 from Dover, Nova Scotia, planet Earth.

Wikipedia Picture of the Day - August 21st, 2020 - Geostationary orbit (Narrated by Brian)
This is an animation showing geocentric satellite orbits, to scale with the Earth, at 3,600 times actual speed. The second-outermost (shown in grey) is a geostationary orbit, 35,786 kilometres (22,236 miles) above Earth's equator and following the direction of Earth's rotation, with an orbital period matching the planet's rotation period (a geosynchronous orbit). An object in such an orbit will appear to occupy a fixed position in the sky. Some 300 kilometres (190 miles) farther away is the graveyard orbit (brown), used for satellites at the end of their operational lives. Nearer to the Earth are the orbits of navigational satellites, such as Galileo (turquoise), BeiDou (beige), GPS (blue) and GLONASS (red), in medium Earth orbits. Much closer to the planet, and within the inner Van Allen belt, are satellites in low Earth orbit, such as the Iridium satellite constellation (purple), the Hubble Space Telescope (green) and the International Space Station (magenta).
