Massive Metal ‘Anomaly’ Detected 180 Miles Beneath The Surface Of The Moon
The metal mass is five times bigger than the Big Island of Hawaii.

Scientists say they’ve detected a huge metal mass “firmly embedded” beneath a crater on the moon, possibly the remnants of a massive asteroid strike billions of years ago.

According to a study published in April in the journal Geophysical Research Letters, the mass is located about 180 miles under the surface of the 1,240-mile-long South Pole-Aitken basin on the far side of the moon, the largest known preserved crater in the solar system.

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground,” lead author Peter B. James, founder of Baylor University’s Planetary Research Group, said in a news release. “That’s roughly how much unexpected mass we detected.”

The metals were discovered using data from NASA’s Gravity Recovery and Interior Laboratory and the Lunar Reconnaissance Orbiter.

The study proposes two possible explanations.

One is that “the asteroid that formed this crater is still embedded in the Moon’s mantle” rather than sinking into its core after an impact some 4 billion years ago, James said.

The other is that the mass contains the remnants of the moon’s magma ocean, with the oxides concentrating there as it solidified when it cooled billions of years ago.

James said the dense metal mass ― “whatever it is, wherever it came from” ― is so heavy it’s weighing down the basin floor by more than half a mile.

“That’s a huge result,” NASA lunar geologist Daniel Moriarty told National Geographic. “It really gives us a hint of what’s going on in the lunar interior.”

The Moon is lopsided, which is probably the main reason why it shows the same face to the Earth. That lopsidedness is likely the result of a centrifugal force caused by the far side of the Moon being heavier than the near side.

But the Moon also wobbles. Over the course of an orbit, it oscillates back and forth, and up and down. It also gets closer and farther, due to the eccentricity of its orbit.

Here's how the Moon's appearance would change over an orbit, if it was full the entire time:

Māori are the native people of New Zealand

Matariki: Everything there is to know about it
Alistair Hughes·18:11, Jun 03 2016

The Maori new year festival begins with the first rising of Matariki (the Pleiades star cluster) today.

EYEING THE CROSS

Southern hemisphere skies offer dazzling spectacles for night viewing.

Image
Royal Astronomical Society of NZ
The Pleiades/Matariki cluster.

The most recognisable constellation (pattern of stars) in the sky is the Southern Cross (Crucis).

Who first depicted them as a cross is unknown, but they are first shown in this fashion on a celestial globe made in 1592. The cross would have been visible on the horizon of Jerusalem during the period in which the crucifixion took place.

Two bright stars on one side of the cross are often referred to as the Pointers, since the imaginary line joining them appears to point towards the constellation.

The brighter one, Alpha Centauri, is the closest star to our Sun.

Nestled against the Southern Cross is a dark cloud-like area, from which stars appear to be absent. Popularly known as the Coal Sack, it is a cloud of gas and dust obscuring the light from the more distant stars of the Milky Way, which silhouettes its outline.

MATARIKI OBSERVANCE (JUNE 6, 2016)

Matariki - Mata Riki (Tiny Eyes) or Mata Ariki (Eyes of God) - is the Maori name for the group of stars also known as the Pleiades star cluster or the Seven Sisters.

They are a group of young stars glowing in the gas and dust of the nebula from which they formed.

Matariki is the name for the traditional Maori new year. This is marked by the rise of Matariki and the sighting of the next new moon.

The pre-dawn rise of Matariki can be seen in the last few days of May every year and the new year is marked at the sighting of the next new moon which occurs during June.

Traditionally, depending on the visibility of Matariki, the coming season's crop was thought to be determined. The brighter the stars, the warmer the season would be, bringing a more productive crop.

WAY UP SOUTH

The constellations were named mostly by northern hemisphere observers, meaning that we see these star patterns from an 'upside-down viewpoint', which makes many of them difficult to identify.

An extremely easy constellation to recognise is Scorpius (the scorpion), a long, S-shaped star pattern located in the widest and brightest part of the Milky Way.

Image

A prominent orange-red star, Antares, represents the heart of the scorpion.

One of the largest stars, it is a red supergiant, and a nearby line of three stars represents the head and claw. On the other side of Antares, a line curving downwards is the scorpion's tail.

The Large & Small Magellanic Clouds (LMC and SMC) are easily seen by eye in a dark sky. They are two galaxies like our own, the Milky Way, but are both much smaller. They are also very close by galactic standards: LMC is 160,000 light years and SMC 200,000 light years away, each composed of billions of stars.

MATARIKI - A REPEATING PATTERN

The star cluster called Matariki has always been significant to many cultures all around the world.

In Greek mythology the Pleiades were the seven daughters of the titan Atlas and the sea-nymph Pleione.

Image

Zeus immortalised the sisters by placing them in the sky, forming the constellation known thereafter as the Pleiades.

The constellation is also known to the Aztecs (who called it Tianquiztli), the Maya (Tzab-ek), the Persians (Parveen/parvin), the Sioux and Cherokee of North America and the Chinese.

In India, this cluster is called the Krittika nakshatra, believed to be the six wives of the star Rishis of the Great Bear.

The Matariki star cluster is mentioned in Homer's Iliad and Odyssey, and three times in the Bible, including Amos 5:8 ("Seek him that maketh the seven stars and Orion...").

As the Krittika, it is particularly revered in Hindu mythology as the six mothers of the war god Skanda, who developed six faces, one for each of them.

Some scholars of Islam have suggested that it is also the Star in Najm which is mentioned in the Koran.

Japanese car maker Subaru derives its name from the Matariki cluster, which is represented by six stars within an oval for its corporate logo.

THE SHORTEST DAY

Image
The Earth's axial tilt of 23.5 degrees means that the southern and northern hemispheres each receive the greatest and least amount of sunlight at opposite times of the year as we orbit the Sun, giving us seasonal changes and solstices.

Winter solstice occurs on the shortest day and longest night of the year, when the Sun's maximum position in the sky is at its lowest. This marks the reversal of the gradual lengthening of darkness hours, bringing the return of longer days and an increase in light and warmth.

Interpretation of the event varies throughout the world, but most cultures celebrate a recognition of rebirth, involving festivals and rituals.

Maruaroa o Takurua occurs from June 20–22, and is seen by Maori as the middle of the winter season. It takes place after the rise of Matariki, marking the beginning of the new year, and is said to be the point at which the Sun turns from his northern journey to his winter-bride Hine-Takurua (Sirius) and begins his journey back to his summer-bride, Hine-Raumati.

In Maori myth, Hine-Takurua symbolises the gathering of fish and seafood from the ocean, while the return of the Sun to Hine-Raumati indicates the time for cultivation of the land.

FINDING MATARIKI


Image

✹ First, find Tautoru (the bottom three stars of 'the pot', also called Orion's belt), in the low northeast just before dawn.

✹ To the left of Tautoru, find the orange star, Taumata-kuku (Aldebaran).

✹ Follow an imaginary line from Tautoru, across to Taumata-kuku and keep going until you hit a small, bright cluster of stars. This is Matariki. In good viewing conditions you should be able to make out seven bluish stars.

MAORI ASTRONOMY

To Maori, the southern Milky Way is Te Waka o Tamarereti (the great waka (canoe) of Tamarereti).

Orion forms the stern, Scorpius is the prow and the Southern Cross and the Pointers are the anchor and rope.

At the time of the Maori new year, the great waka of Tamarereti can be seen in the south and contains all of the important navigational stars.

According to legend, when Tamarereti took his canoe out on to a lake, he found himself far from home as night was falling.

There were no stars at this time and in the darkness he was in danger from the taniwha (monster). So Tamarereti sailed his canoe along the river that emptied into the heavens (to cause rain) and scattered shiny pebbles from the lakeshore into the sky.

The sky god, Ranginui, was pleased by this and placed the waka into the sky as a monument to how the stars were made.

In Japanese it's the Subaru...that's why Subaru's have the star pattern emblem.

I'm in denial about this whole tilt thing...it's summer up here now, and it's staying summer!


This is pretty cool(:
If the universe is only 14 billion years old, how can it be 92 billion light years wide?

There's also the issue of the changing distance of the Earth from the Sun. Its closest point on January 3rd is about 147.1 million kilometres and its farthest point is about 152.1 million kilometres. In January the southern hemisphere is titled towards the Sun and on top of that, the Sun is 5 million kilometres closer than it is in July, when the northern hemisphere is tilted towards the Sun. Summer in the southern hemisphere can be brutal.

Intensity of radiation is inversely proportional to the square of the distance, so, all else being equal, the sun actually seems 16% brighter in the sky in January than it does in July. But, in the northern hemisphere in January, the Earth is titled away from the Sun, which is low on the horizon and passing through more atmosphere at a low angle for less than 12 hours of the day (much less in places like southern England and Northern France where my genes come from - London has only roughly 8 hours daylight out of 24 in January), while in the southern hemisphere, like where I grew up from age five, in January, the sun is high in the sky and there are roughly 14 hours of daylight out of 24.

So, England gets the nasty sun in the middle of winter (with compensations) and Australia gets it in the middle of summer - it's unbearable. If you've ever wondered about why our skin cancer rates are the highest in the world, there's an explanation.

NASA sold moon landing footage to an intern for $218. Now, the tapes could sell for millions

Image

(CNN) On July 20, 1969, NASA put a man on the moon and captured it all on tape.

In 1976, the space agency unknowingly sold those tapes of original footage from the Apollo 11 lunar mission to a lucky intern who held onto them for decades. He never even knew their contents.

Now, NASA's blunder will belong to the highest bidder: the three surviving videotapes of the seminal moment in space exploration are up for auction--at a starting bid of $700,000.

According to Sotheby's, the tapes are worth up to $2 million. Bidding begins July 20, on the 50th anniversary of the moon landing.

The two-and-a-half hours of footage provide the sharpest image of the history-making mission ever recorded, from Neil Armstrong's first steps on the moon's surface to an interplanetary conversation with then-President Richard Nixon to the planting of the American flag.

The tapes, which could fetch millions at auction, feature NASA footage of the moment Neil Armstrong and Buzz Aldrin planted the American flag on the moon.

The tapes, which could fetch millions at auction, feature NASA footage of the moment Neil Armstrong and Buzz Aldrin planted the American flag on the moon.

The tapes were sold by accident to NASA intern Gary George in 1976, who purchased the set unknowingly among 65 boxes of videotapes at a government surplus auction for $217.77.

He resold most of the tapes to local TV stations for a profit but held onto three of them labeled "APOLLO 11 EVA | July 20, 1969 REEL 1 [-3]" at his father's suggestion, according to Sotheby's.

It's wise he did: an EVA, or extravehicular activity, is also known as a spacewalk, and his tapes captured the first lunar EVA.

More than 30 years later, after George heard NASA was trying to track down the footage for the moon landing's 40th anniversary, he took the unidentified tapes to a video archivist and viewed them for the first time.

It was then he realized he'd accidentally purchased the sharpest footage of the lunar landing ever recorded.

Whoever purchases the footage will join an exclusive club of viewers: George watched the tapes once more to digitize them and save them on a hard drive, which is included in the tapes' sale. Sotheby's staff viewed them once to assess their quality, which they found to be "faultless."

Still, it's unlikely the highest bidder will snag a bargain like George did.

Asteroid cruised close to Earth on Friday
Friday, July 19, 2019 10:38PM EDT

An asteroid was expected to travel closely past the Earth on Friday, but according to data collected by the Center for Near Object Studies, this extraterrestrial tourist is only one of many.

The asteroid, called 2019 NJ2, is somewhere between 28 and 63 metres in diameter, and is travelling at 48,456 kilometres per hour, or 13.46 km per second.

The Center for Near Object Studies (CNEOS) tracks, as the name suggests, near-earth objects (NEOs, for short). A near-earth object is an asteroid or comet that will be passing close to the Earth’s orbit as it hurtles through space, tugged about by the gravitational pull of the planets and objects around it.
