Sun pillar with upper tangent arc ✨ This was not a typical sun pillar. Just after sunrise in Early February 2021 in Providence, Rhode Island, USA, a photographer, looking out his window, was suddenly awestruck. The astonishment was caused by a sun pillar that fanned out at the top. Sun pillars, singular columns of light going up from the Sun, are themselves rare to see, and are known to be caused by sunlight reflecting from wobbling, hexagon-shaped ice-disks falling through Earth's atmosphere. Separately, upper tangent arcs are known to be caused by sunlight refracting through falling hexagon-shaped ice-tubes. Finding a sun pillar connected to an upper tangent arc is extraordinary, and, initially, took some analysis to figure out what was going on. A leading theory is that this sun pillar was also created, in a complex and unusual way, by falling ice tubes. Few might believe that such a rare phenomenon was seen again if it wasn't for the quick thinking of the photographer -- and the camera on his nearby smartphone. Credit : APOD, NASA

A Desert Eclipse Image Credit & Copyright: Maxime Daviron Explanation: A good place to see a ring-of-fire eclipse, it seemed, would be from a desert. In a desert, there should be relatively few obscuring clouds and trees. Therefore late December of 2019, a group of photographers traveled to the United Arab Emirates and Rub al-Khali, the largest continuous sand desert in world, to capture clear images of an unusual eclipse that would be passing over. A ring-of-fire eclipse is an annular eclipse that occurs when the Moon is far enough away on its elliptical orbit around the Earth so that it appears too small, angularly, to cover the entire Sun. At the maximum of an annular eclipse, the edges of the Sun can be seen all around the edges of the Moon, so that the Moon appears to be a dark spot that covers most -- but not all -- of the Sun. This particular eclipse, they knew, would peak soon after sunrise. After seeking out such a dry and barren place, it turned out that some of the most interesting eclipse images actually included a tree in the foreground, because, in addition to the sand dunes, the tree gave the surreal background a contrasting sense of normalcy, scale, and texture. On Saturday, October 14, a new ring of fire will be visible through clear skies from a thin swath crossing both North and South America. #PhoenixDelivers #nasa

The Lagoon Nebula, also known as Messier 8 or M8, is a giant interstellar cloud in the constellation Sagittarius. It is a stellar nursery, where new stars are actively forming. The nebula is about 4,000-6,000 light-years away from Earth and is one of the brightest and most massive star-forming regions in the Milky Way. Its distinctive shape resembles a lagoon, hence its name. The Lagoon Nebula is visible to the naked eye under dark skies and is a popular target for amateur astronomers and astrophotographers. This was an observation made with the Las Cumbres Observatory 0.4m telescope with exposure time of 300 seconds for each of the Red, Blue and Green filters. The raw images were processed with Fits liberator and the Gimp software at PACS e-Lab.

The story of an iconic picture "Pale Blue Dot" Earth – our home. On this "pale blue dot" resides everyone who ever lived, their joys and sorrows, triumphs and tragedies, playing out against the vastness of space. Every individual, from mighty kings to ordinary people, all share this tiny stage. This is the only known cradle of life in the universe, a humbling realization that underscores our responsibility to cherish and protect it. The camera lingers on the Earth before fading to black, the narrator's final whisper echoing: "the only home we've ever known." The Pale Blue Dot is an iconic photograph of Earth captured by the Voyager 1 space probe in 1990. Taken from a distance of around 6 billion kilometers (3.7 billion miles) as Voyager 1 was departing our solar system, the image portrays Earth as a tiny, pale blue speck in the vastness of space. This image is a powerful reminder of our planet's isolation and fragility in the cosmic expanse, highlighting the need for responsible stewardship of our home. The photograph was a result of astronomer Carl Sagan's suggestion to turn Voyager's camera back towards Earth, offering a profound perspective on our place in the universe. #cosmos #niel_degrasse_tyson #carl_sagan #astrophysics #astrophotography #astronomy

The Moon will pass in front of the Sun, creating a total eclipse of the Sun visible from Mexico, the eastern Contiguous United States and south-eastern Canada between 21:13 and 02:22 IST. Solar eclipses occur when the Sun, Moon and Earth are aligned in a straight line, so that the Moon passes between us and the Sun and blocks its light. Observing the Sun can be very dangerous if it is not done with the right equipment. The Sun is the brightest object in the sky, and looking directly at it can cause permanent eye damage within seconds. Viewing it through any optical instrument – even a pair of binoculars or the finderscope on the side of a telescope – can cause instant and permanent blindness. If you have any doubts about whether your equipment is safe, it is best not to risk using it. By far the safest thing to do is to go along to a public observing event. Many astronomical societies are likely to be hosting observing events on the day, and they'll be sure to welcome newcomers. You may meet some new people at the same time as seeing the eclipse. #solareclipse #totalsolareclipse #solarsystem #spacenews #sun #photography #astronomylover #astrophotography #moon #earth #celestial

The Pleiades, The Pleiades, also known as the Seven Sisters, is an open star cluster located in the constellation of Taurus. It is one of the closest star clusters to Earth and is easily visible to the naked eye. The cluster is dominated by hot, young blue stars, with the brightest members forming a distinctive group of stars resembling a small dipper. In Greek mythology, the Pleiades were the daughters of Atlas and Pleione, and they were pursued by Orion. The cluster has been observed and referenced by various cultures throughout history. Today, it is a subject of scientific study, providing valuable insights into stellar evolution and dynamics. This was an observation made by PACS e-Lab citizen astronomers with the Las Cumbres Observatory's 0.4m telescope with exposure time of 300 seconds for each of the Red, Blue and Green filters. The raw images were processed with Fits liberator and the Gimp software.

Ice Halos over Bavaria Image Credit & Copyright: Bastian Werner Explanation: What's causing those unusual sky arcs? Ice crystals. While crossing a field of fresh snow near Füssen, Bavaria, Germany, earlier this month, the photographer noticed that he had entered an ice fog. For suspended water to freeze into an ice fog requires quite cold temperatures, and indeed the air temperature on this day was measured at well below zero. The ice fog reflected light from the Sun setting behind St. Coleman Church. The result was one of the greatest spectacles the photographer has ever seen. First, the spots in the featured picture are not background stars but suspended ice and snow. Next, two prominent ice halos are visible: the 22-degree halo and the 46-degree halo. Multiple arcs are also visible, including, from top to bottom, antisolar (subsun), circumzenithal, Parry, tangent, and parhelic (horizontal). Finally, the balloon shaped curve connecting the top arc to the Sun is the rarest of all: it is the heliac arc, created by reflection from the sides of hexagonally shaped ice crystals suspended in a horizontal orientation. #PhoenixDelivers #nasa

Gravitational Time Dilation ⏳⌛️ One unique and interesting fact about black holes is that, according to the theory of general relativity, time seems to slow down near the event horizon—the boundary of the black hole. To an external observer, objects falling into a black hole appear to slow down and never actually pass through the event horizon, instead becoming dimmer and eventually fading away. This effect is known as gravitational time dilation, where the gravity of the black hole is so strong that it warps the fabric of spacetime itself. However, from the perspective of the object falling in, it crosses the event horizon without any sense of stopping, potentially reaching the singularity, the point of infinite density at the black hole's core, in finite time. #environment #nature #sustainability #climatechange #ecofriendly #space #blackhole #earth #SpaceExploration, #CosmicWonders, #GalacticJourney, #StarryNights, #AstronomyLovers, #DeepSpace, #BlackHolesMystery, #NebulaeDreams, #PlanetaryScience, #Astrophotography, #UniverseMysteries, #CosmicEvents, #InterstellarTravel, #CelestialBeauty #DarkMatterDiscoveries #love #envirolab

During a geomagnetic storm, charged particles from the sun, known as solar wind, interact with the Earth’s magnetic field. When these charged particles are directed towards the Earth and interact with its magnetic field, they can cause disturbances. This interaction results in an increase in the intensity and frequency of the Northern Lights, making them more visible and vibrant, even in lower latitudes. The heightened activity creates stunning displays of colorful lights dancing across the night sky. Astronomers and space weather forecasters monitor solar activity to predict when geomagnetic storms may occur, allowing enthusiasts to prepare for potential Northern Lights sightings. #AuroraBorealis #NorthernLights #NightSkyMagic #CelestialDance #NatureSpectacle #Astrophotography #AuroraChasers #SkyGazing #SolarParticles #EtherealBeauty
