Astronomy Picture of the Day - August 7th, 2021 - Jezero Crater: Raised Ridges in 3D (Narrated by Emma)
Get out your red-blue glasses and hover over the surface of Mars. Taken on July 24, the 3D color view is from the Mars Ingenuity Helicopter's 10th flight above the Red Planet. Two images from Ingenuity's color camera, both captured at an altitude of 12 meters (40 feet), but a few meters apart to provide a stereo perspective, were used to construct the color anaglyph. Ingenuity's stereo images were made at the request of the Mars Perseverance rover science team. The team is considering a visit to these raised ridges on the floor of Jezero Crater during Perseverance's first science campaign.
Wikipedia Picture of the Day - July 22nd, 2023 - Lake Sherburne (Narrated by Amy)
Lake Sherburne is located in the Many Glacier region of Glacier National Park, in the U.S. state of Montana. The lake is a reservoir, formed by Lake Sherburne Dam, which impounded Swiftcurrent Creek and was constructed in between 1914 and 1921.

Wikipedia Picture of the Day - December 15th, 2023 - Tim Peake (Narrated by Brian)
Tim Peake (born 1972) is a British military officer and astronaut. On 15 December 2015, he embarked on a mission to the International Space Station (ISS), becoming the second astronaut wearing the British flag in space, after Helen Sharman. After graduating from Royal Military Academy Sandhurst, Peake served in various military roles between 1992 and 2009, accumulating 3,000 flying hours. He was then selected to join the European Space Agency's astronaut corps where he was trained and took part in missions such as in the Aquarius Reef Base, in which he spent twelve days underwater. During his mission to the ISS, Peake supported a spacewalk by two American astronauts before carrying out a spacewalk himself to replace a faulty sequential shunt unit on the station's solar arrays. He also participated in several UK events from space, such as delivering a new year's message broadcast on the BBC and remotely presenting an award to singer Adele in the Brit Awards 2016. Peake returned to Earth in June 2016, having completed 3,000 orbits of Earth, and retired from active service in 2023. This official NASA photograph of Peake was taken in 2013.

Astronomy Picture of the Day - June 7th, 2021 - A Bright Nova in Cassiopeia (Narrated by Emma)
What’s that new spot of light in Cassiopeia? A nova. Although novas occur frequently throughout the universe, this nova, known as Nova Cas 2021 or V1405 Cas, became so unusually bright in the skies of Earth last month that it was visible to the unaided eye. Nova Cas 2021 first brightened in mid-March but then, unexpectedly, became even brighter in mid-May and remained quite bright for about a week. The nova then faded back to early-May levels, but now is slightly brightening again and remains visible through binoculars. Identified by the arrow, the nova occurred toward the constellation of Cassiopeia, not far from the Bubble Nebula. A nova is typically caused by a thermonuclear explosion on the surface of a white dwarf star that is accreting matter from a binary-star companion -- although details of this outburst are currently unknown. Novas don't destroy the underlying star, and are sometimes seen to recur. The featured image was created from 14 hours of imaging from Detroit, Michigan, USA. Both professional and amateur astronomers will likely continue to monitor Nova Cas 2021 and hypothesize about details of its cause.

Astronomy Picture of the Day - February 28th, 2023 - Crescent Moon Beyond Greek Temple (Narrated by Amy)
Why is a thin crescent moon never seen far from a horizon? Because the only geometry that gives a thin crescent lunar phase occurs when the Moon appears close to the Sun in the sky. The crescent is not caused by the shadow of the Earth, but by seeing only a small part of the Moon directly illuminated by the Sun. Moreover, the thickest part of the crescent always occurs in the direction of the Sun. In the evening, a thin crescent Moon will set shortly after the Sun and not be seen for the rest of the night. Alternatively, in the morning, a crescent Moon will rise shortly before the Sun after not being seen for most of the night. Pictured two weeks ago, a crescent moon was captured near the horizon, just before sunrise, far behind remnants of the ancient Temple of Poseidon in Greece.

Wikipedia Picture of the Day - March 16th, 2021 - Saint Petersburg (Narrated by Salli)
Saint Petersburg, the second-largest city in Russia, is situated at the head of the Gulf of Finland on the Baltic Sea. This photograph shows the eastern end of Vasilyevsky Island, known as the spit, surrounded by the river Neva. The Old Saint Petersburg Stock Exchange and Rostral Columns, built in the Greek Revival style in the first decade of the nineteenth century, is visible in the centre.

Astronomy Picture of the Day - May 29th, 2024 - Stairway to the Milky Way (Narrated by Salli)
What happens if you ascend this stairway to the Milky Way? Before answering that, let's understand the beautiful sky you will see. Most eye-catching is the grand arch of the Milky Way Galaxy, the band that is the central disk of our galaxy which is straight but distorted by the wide-angle nature of this composite image. Many stars well in front of the Milk Way will be visible, with the bright white star just below the stellar arch being Altair, and the bright blue star above it being Vega. The air glows green on the left, just above the yellow cloud deck. The featured image was taken last month on Portugal's Madeira Island in the North Atlantic Ocean. Oh, and what happens after you reach the top of these stairs and admire the amazing sky is, quite probably, that you then descend down the stairs on the other side.

Astronomy Picture of the Day - December 30th, 2021 - The Further Tail of Comet Leonard (Narrated by Joanna)
Comet Leonard, brightest comet of 2021, is at the lower left of these two panels captured on December 29 in dark Atacama desert skies. Heading for its perihelion on January 3 Comet Leonard's visible tail has grown. Stacked exposures with a wide angle lens (also displayed in a reversed B/W scheme for contrast), trace the complicated ion tail for an amazing 60 degrees, with bright Jupiter shining near the horizon at lower right. Material vaporizing from Comet Leonard's nucleus, a mass of dust, rock, and ices about 1 kilometer across, has produced the long tail of ionized gas fluorescing in the sunlight. Likely flares on the comet's nucleus and buffeting by magnetic fields and the solar wind in recent weeks have resulted in the tail's irregular pinched and twisted appearance. Still days from its closest approach to the Sun, Comet Leonard's activity should continue. The comet is south of the Solar System's ecliptic plane as it sweeps through the southern constellation Microscopium.

Astronomy Picture of the Day - January 19th, 2021 - A Lunar Corona with Jupiter and Saturn (Narrated by Amy)
Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar Coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. Solar coronae are also sometimes evident. The featured composite image was captured a few days before the close Great Conjunction between Saturn and Jupiter last month. In the foreground, the Italian village of Pieve di Cadore is visible in front of the Sfornioi Mountains. New: APOD is now available in Taiwanese from National Central University
