NASA Astronomy Picture of the Day:

Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bulge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.

"Dietary supplements are a big business. The industry made almost US$39 billion in revenue in 2022, and has very little regulation and oversight...Supplements are regulated as food instead of drugs, even though they can interact with medications and may be laced with hidden drugs not included on the label....The FDA’s website states that “many dietary supplements contain ingredients that have strong biological effects which may conflict with a medicine you are taking or a medical condition you may have." More at The Conversation ➜

"Chances of getting records from a federal agency drop. An analysis of 37,000 Freedom of Information Act requests submitted to federal agencies through MuckRock.com shows that in 2010, barely more than half of requests yielded the records sought. But by 2022, barely more than 10% of requests met with success". More at The Conversation ➜

NASA Astronomy Picture of the Day:

What phase of the Moon is 3.14 radians from the Sun? The Full Moon, of course. Even though the Moon might look full for several days, the Moon is truly at its full phase when it is Pi radians (aka 180 degrees) from the Sun in ecliptic longitude. That's opposite the Sun in planet Earth's sky. Rising as the Sun set on March 9, 2020, only an hour or so after the moment of its full phase, this orange tinted and slightly flattened Moon still looked full. It was photographed opposite the setting Sun from Teide National Park on the Canary Island of Tenerife. Also opposite the setting Sun, seen from near the Teide volcano peak about 3,500 meters above sea level, is the mountain's rising triangular shadow extending into Earth's dense atmosphere. Below the distant ridge line on the left are the white telescope domes of Teide Observatory. Again Pi radians from the Sun, on March 25 the Full Moon will dim slightly as it glides through Earth's outer shadow in a penumbral lunar eclipse.

Pi Day π (pi) is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant digits of π. Pi (π) Day has become an international holiday, celebrated live and online all around the world. 

What is π anyway? Divide any circle’s circumference by its diameter; the answer (whether for a plate or a planet) is always approximately 3.14, a number represented with the Greek letter π. Mathematicians have been calculating π’s digits with more and more accuracy and have discover they go on literally forever, with no pattern.

NASA Astronomy Picture of the Day:

A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker: the Seagull Nebula. This portrait of the cosmic bird covers a 2.5-degree wide swath across the plane of the Milky Way, near the direction of Sirius, alpha star of the constellation of the Big Dog (Canis Major). Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission and reflection nebula with an embedded massive star that forms the bird's head. Likely part of a larger shell structure swept up by successive supernova explosions, the broad Seagull Nebula is cataloged as Sh2-296 and IC 2177. The prominent bluish arc below and right of center is a bow shock from runaway star FN Canis Majoris. Dominated by the reddish glow of atomic hydrogen, this complex of gas and dust clouds with other stars of the Canis Majoris OB1 association spans over 200 light-years at the Seagull Nebula's estimated 3,800 light-year distance.

Josep Borrell remarks at the United Nations, N.Y: 

“But this is a humanitarian crisis, which is not a natural disaster. It’s not a flood. It’s not an earthquake. It’s man-made. And when we look for alternative ways of providing support, by sea or by air, we have to remind that we have to do it because the natural way of providing support, through roads, is being closed, artificially closed, and starvation is being used as a war arm. And when we condemn this happening in Ukraine, we have to use the same words for what’s happening in Gaza.”

"We are now facing a population fighting for their own survival,"  

A Spanish ship has left Cyprus for Gaza carrying urgently needed food supplies but the UN says this cannot replace the delivery of aid by land.

The growth of Data Centers is taxing our power systems. Now we are learning that they are also using our scared water resources. More at Noema ➜

NASA Astronomy Picture of the Day:

What's that over the horizon? What may look like a strangely nearby galaxy is actually a normal rocket's exhaust plume -- but unusually backlit. Although the SpaceX Falcon 9 rocket was launched from Cape Canaveral in Florida, USA, its burned propellant was visible over a much wider area, with the featured photograph being taken from Akureyri, Iceland. The huge spaceship was lifted off a week ago, and the resulting spectacle was captured soon afterward with a single 10-second smartphone exposure, before it quickly dissipated. Like noctilucent clouds, the plume's brightness is caused by the Twilight Effect, where an object is high enough to be illuminated by the twilight Sun, even when the observer on the ground experiences the darkness of night. The spiral shape is likely caused by high winds pushing the expelled gas into the shape of a corkscrew, which, when seen along the trajectory, looks like a spiral. Stars and faint green and red aurora appear in the background of this extraordinary image.

"In early 2015, the 10,000-entry Oxford children’s dictionary dropped around fifty words related to nature — words like fern, willow, and starling — in favor of terms like broadband and cut and paste, some of the world’s most prominent authors composed an open letter of protest and alarm at this impoverishment of children’s vocabulary and its consequent diminishment of children’s belonging to and with the natural world. Among them was one of the great nature writers of our time: Robert Macfarlane....Troubled by this loss of vital and vitalizing language, MacFarlane teamed up with illustrator and children’s book author Jackie Morris, who had reached out to him to write an introduction for a sort of “wild dictionary” she wanted to create as a counterpoint to Oxford’s erasure. Instead, Macfarlane envisioned something greater. The Lost Words: A Spell Book (public library) was born" . Read more at the Marginalian

NASA Astronomy Picture of the Day:

What glows in the night? This night featured a combination of usual and unusual glows. Perhaps the most usual glow was from the Moon, a potentially familiar object. The full Moon's nearly vertical descent results from the observer being near Earth's equator. As the Moon sets, air and aerosols in Earth's atmosphere preferentially scatter out blue light, making the Sun-reflecting satellite appear reddish when near the horizon. Perhaps the most unusual glow was from the bioluminescent plankton, likely less familiar objects. These microscopic creatures glow blue, it is thought, primarily to surprise and deter predators. In this case, the glow was caused primarily by plankton-containing waves crashing onto the beach. The image was taken on Soneva Fushi Island, Maldives just over one year ago.

NASA Astronomy Picture of the Day:

Would you go to the end of the world to see a total eclipse of the Sun? If you did, would you be surprised to find someone else there already? In 2003, the Sun, the Moon, Antarctica, and two photographers all lined up in Antarctica during an unusual total solar eclipse. Even given the extreme location, a group of enthusiastic eclipse chasers ventured near the bottom of the world to experience the surreal momentary disappearance of the Sun behind the Moon. One of the treasures collected was the featured picture -- a composite of four separate images digitally combined to realistically simulate how the adaptive human eye saw the eclipse. As the image was taken, both the Moon and the Sun peeked together over an Antarctic ridge. In the sudden darkness, the magnificent corona of the Sun became visible around the Moon. Quite by accident, another photographer was caught in one of the images checking his video camera. Visible to his left are an equipment bag and a collapsible chair. A more easily visible solar eclipse will occur in just under four weeks and be visible from a long, thin swath of North America.
