    An object uncovered by archaeologists in Norfolk, England, is “completely unlike” anything else ever discovered, experts said Monday. The tiny 19.4 mm (o.7 inch) object is a gilded silver relic, adorned with intricate designs appearing to show an animal looking over its shoulder, according to The Telegraph. The piece is believed to be at least 1,200 years old and archaeologists reportedly can’t determine the purpose of the mysterious object. Detectorists found the piece in a crumpled condition, but it appears to be a round object with shallow sides, making it somewhat dish-shaped. “It was made by someone with a real...
  • The Maya coveted mercury. It may have hastened their downfall.

    08/17/2023 6:56:49 AM PDT · by BenLurkin · 38 replies
    Maya... were entranced by elemental mercury as well as its vermillion-hued offspring, mercury sulfide, also known as cinnabar. Cinnabar is by far the most prevalent of the two compounds in the archaeological record. Archaeologists have unearthed numerous artifacts made of it and turned up evidence that the Maya extensively used cinnabar-based paints. Pure elemental mercury is a rarer find, usually linked with ritual caches or elite burials. One of the most dazzling discoveries was a bulbous vessel retrieved from an underwater site in Guatemala holding as much as 500 cubic centimeters of elemental mercury. The wide presence of the toxic...

    A new analysis of chaos in the solar system reveals how planetary collisions are avoided over billions of years.Earth probably shouldn't exist. That's because the orbits of the inner solar system planets — Mercury, Venus, Earth and Mars — are chaotic, and models have suggested that these inner planets should have crashed into each other by now. And yet, that hasn't happened. New research published May 3 in the journal Physical Review X(opens in new tab) may finally explain why. Through a deep plunge into the models for planetary motion, the researchers discovered that the motions of the inner...

    Have you seen the “planetary parade” after sunset? It’s getting a lot of media attention, partly because Jupiter is about to sink into the Sun’s glare and ruin it, but you can glimpse some to all of the five planets naked-eye and with binoculars on any night this week. Mercury, Jupiter, Venus, Uranus and Mars are all visible right after sunset. Get somewhere high with a clear view of the western horizon to watch the sunset. After sunset have a look for Jupiter and Mercury very close to the horizon. You may need binoculars. Above them will be a very...
  • Mercury Joins Great Planet Alignment

    During the past couple of weeks, skywatchers around the world have been observing the western evening sky soon after sundown, as four naked-eye planets -- Venus, Mars, Saturn and Jupiter - have stretched out in a long line. The line has slowly contracted each night, as the four planets draw closer to each other.Even the Moon got involved, closely passing each of the four planets over a span of five nights in mid-April. Now through the first days of May will likely be the best time to see yet a fifth planet: Mercury. Mercury has actually been visible for the...

    A grand celestial reunion is due in Earth’s skies throughout June. Sky-watchers will get a rare chance to see all the major planets in our solar system bunched together—with the moon joining the festivities, too, from June 17 to June 27. This rare alignment includes the five planets easily spotted with the naked eye: Mercury, Venus, Mars, Jupiter, and Saturn. Each is bright enough to be seen even in light-polluted city skies, with brilliant Venus being the brightest and Mercury the faintest. Our closest planets will appear to be arranged across the sky in the same order as their distance...

    This Sunday, April 17th, Jupiter will move into position closest to the eastern horizon, and almost on top of Venus. A bit south and above will be Mars looking very red, and then Saturn further up and further south. For most people in North America, the ideal time will be to go out and look southeast about 45 minutes before the sun begins to rise. On April 23rd, the Moon will appear in conjunction with the other spheres, appearing to the right and above Saturn, before moving off again by April 29th. In mid-June, due to its rapid orbiting around...

    Jupiter, Mercury, Venus, Uranus and Mars are expected to align March 28.. A spectacular celestial sight is on the horizon and you won't want to miss it. Planets Jupiter, Mercury, Venus, Uranus and Mars are expected to align in the night sky on March 28. Planetary alignments occur when the orbit of several planets coincide with each other and they appear to be lined up in the sky. Alignments typically only include two or three planets and are fairly brief, making a 5-planet alignment fairly noteworthy. This rare planetary parade will first become visible in the western sky just after...

    So, after dodging it for nearly three years (and precisely 14 days post-omicron booster), the little SOB finally got me. Pretty crappy timing if you ask me. Rather than bitch and moan about how lousy I feel (plenty), I found something else to bitch and moan about: Digital thermometers. I hate them on the molecular level because, in my limited experience, they work properly about 0% of the time. And what could be a better opportunity for generating a superior dataset than neurotically checking my temperature every 17 seconds? But it did not go well. I experienced thermomageddon at the...

    Toxic levels of a pollutant commonly associated with the wastes of modern industry have been uncovered amid the most unlikely of archaeological sites. Long before conquistadors from far-off lands introduced the decay of war and disease, Maya cultures were dusting the soils of their urban centers with the heavy metal mercury. - snip - "Discovering mercury buried deep in soils and sediments in ancient Maya cities is difficult to explain, until we begin to consider the archaeology of the region which tells us that the Maya were using mercury for centuries." - snip - Perhaps the most widely used form...

    Five planets will be visible in the predawn sky this weekend, offering an opportunity for sky watchers to see a rare alignment of Mercury, Venus, Mars, Jupiter and Saturn with the naked eye. Beginning Friday and lasting through this month, the five planets will appear strung across the eastern horizon before sunrise. The parade of planets will be aligned in order of their distance from the sun, with Mercury, closest to the star, appearing lowest on the horizon and Saturn highest in the night sky. For the best views, sky watchers in the Northern Hemisphere should head outside roughly 30...
  • Astronomy Picture of the Day - Mercury's Sodium Tail

    05/03/2022 4:09:47 PM PDT · by MtnClimber · 13 replies ^ | 3 May, 2022 | Image Credit & Copyright: Sebastian Voltmer
    Explanation: That's no comet. Below the Pleiades star cluster is actually a planet: Mercury. Long exposures of our Solar System's innermost planet may reveal something unexpected: a tail. Mercury's thin atmosphere contains small amounts of sodium that glow when excited by light from the Sun. Sunlight also liberates these atoms from Mercury's surface and pushes them away. The yellow glow from sodium, in particular, is relatively bright. Pictured, Mercury and its sodium tail are visible in a deep image taken last week from La Palma, Spain through a filter that primarily transmits yellow light emitted by sodium. First predicted in...

    We all know why mercury is extremely hot and have a valid reason. But It is also proved that its surface is extremely cold also like temperature fell up to -170degrees.On the day its temperature is around 840-degree Fahrenheit (451-degree Celsius) but at night it goes minus 275 Fahrenheit (-170 degrees Celsius.) You can see a change of temperature of nearly 1100 degrees Fahrenheit (600-degree Celcius). It’s all because of Mercury’s thin atmosphere that can not maintain the heat that it gets in the day and because of its huge day and night.

    When British environmental geochemist Jon Hawkings arrived in Greenland for the first time in 2012, he was impressed. “It’s mind-blowing: You look onto the horizon and it’s just ice and it goes on for 150, 200 kilometers at least.” He went to the Arctic with a group of international scientists. Their goal was to investigate the relationship between nutrients entering coastal ecosystems from glacial meltwater. But the group’s research took an unexpected turn. The scientists analyzed samples from meltwater rivers and fjords and found concentrations of dissolved mercury among the highest ever recorded. Despite it being a pristine and remote...

    Explanation: Sixty years ago, near the dawn of the space age, NASA controllers "lit the candle" and sent Mercury astronaut Alan Shepard arcing into space atop a Redstone rocket. His cramped space capsule was dubbed Freedom 7. Broadcast live to a global television audience, the historic Mercury-Redstone 3 (MR-3) spacecraft was launched from Cape Canaveral Florida at 9:34 a.m. Eastern Time on May 5, 1961. The flight of Freedom 7, the first space flight by an American, followed less than a month after the first human venture into space by Soviet Cosmonaut Yuri Gagarin. The 15 minute sub-orbital flight achieved...
