Mysterious white light on Mars seen in NASA photo

By Chris Ciaccia | Fox News

NASA has released a photo taken by its Curiosity rover that shows a mysterious, unexplained white light on Mars.

The black-and-white raw image was taken by the rover’s right “navcam” (which acts as sort of an eye) on June 16, 2019 or Sol 2438, and transmitted back to Earth. The navcam snapped the picture at 03:53:59 UTC.

The rover has two navcams and 17 cameras and it has been sending photographs continuously since it landed on the Red Planet in August 2012, nearly seven years ago.

It’s unclear exactly what the white spot on the photograph is, as images taken almost immediately before and after do not show the mysterious white light. The images below, also released publicly, were taken at 03:53:46 UTC and 03:54:12 UTC.

This is not the first time an anomaly of this sort has been spotted by Curiosity on Mars. In 2014, a separate mysterious white spot was seen by the rover on April 3, or Sol 589. At the time, JPL scientist Dr. Justin Maki said he believed the light could be a glint from the “rock surface reflecting the Sun.”

In December 2018, Curiosity detected a “shiny” object which may be a meteorite, but NASA researchers were not sure at the time. “The planning team thinks it might be a meteorite because it is so shiny,” NASA wrote in a November 2018 mission update. “But looks can deceive, and proof will only come from the chemistry.”

Mysterious Nazca Lines reveal their secrets

Scientists are shedding new light on the mysterious Nazca Lines etched in the desert of southern Peru, revealing what some of the drawings actually depict.

UNESCO World Heritage Site located about 249 miles south of Lima, the Lines are regarded as one of archaeology’s great mysteries. The lines are scratched into the dark ground to reveal the lighter-colored earth underneath, and are best viewed from the air. They depict a range of animals, plants, imaginary beings and geometric figures.

Experts from the Hokkaido University Museum, the Yamashina Institute for Ornithology and Yamagata University in Japan studied the 16 bird geoglyphs among the more than 2,000 drawings in the area.

“Until now, the birds in these drawings have been identified based on general impressions or a few morphological traits present in each figure,” said Masaki Eda of the Hokkaido University Museum, in a statement. “We closely noted the shapes and relative sizes of the birds’ beaks, heads, necks, bodies, wings, tails and feet and compared them with those of modern birds in Peru.”

The research re-classified a previously identified hummingbird as a hermit.

The scientists were then able to reclassify some of the drawings. One famous shape carved into the desert, long thought to be a hummingbird, actually depicts a hermit, they say. Another drawing, which was previously thought to be a guano bird, is actually a pelican, as is another long unidentified bird among the drawings.

“The Nasca people who drew the images could have seen pelicans while food-gathering on the coast,” Eda explained. “Our findings show that they drew exotic birds, not local birds, and this could be a clue as to why they drew them in the first place.”

Etched into the ground by pre-Inca people, the Nazca Lines date from 400 B.C. to 1000 A.D. Mystery, however, still swirls around why they were created. Theories include that they are a primitive Sun calendar, an irrigation system or even an alien landing strip, according to LiveScience.

With its long and thin bill, short legs, three toes facing the same direction, and the long tail with an elongated middle section, the previously identified hummingbird is re-classified as a hermit. In Peru, long and pointed tails only occur in hermits whereas the tails of typical hummingbirds are forked or fan-shaped. (Eda M., Yamasaki T., Sakai M. Journal of Archaeological Science: Reports. June 20, 2019)

NASA will let tourists visit the International Space Station starting in 2020

NASA plans to allow tourists to visit the International Space Station from 2020 – at an estimated cost of more than $50 million (£39 million) per trip.

Until now, the floating space lab has only been accessible to astronauts representing state-level space agencies.

In a surprise announcement today, NASA confirmed that it would be “opening the International Space Station for commercial business”.

It means that private companies will be able to take “private astronauts” to the ISS for up to 30 days.

“The agency can accommodate up to two short-duration private astronaut missions per year to the International Space Station,” Nasa explained.

“These missions will be privately funded, dedicated commercial spaceflights.”

Transport will be provided by both Boeing and Elon Musk’s SpaceX, who are currently developing capsules that can carry humans to the ISS.

It’s expected that a trip will likely cost around $50 million (£39 million) per astronaut, according to early estimates – but could easily rise well above that figure.

The spaceflight to the ISS will account for a large chunk of the cost.

NASA typically pays around $75 million for seats aboard a Soyuz spacecraft destined for the ISS, and even paid $82 million per seat in 2015.

However, NASA says seats aboard the SpaceX Crew Dragon and/or Boeing CST-100 capsules will cost roughly $58 million per seat.

It’s these capsules that will be used to ferry astronauts up to the ISS – but the cost continues to rise after the journey.

Keeping astronauts on board the ISS is a pricey business.

For instance, regenerative life support and toilet cost $11,250 (£8,800) per astronaut each day.

And general supplies – like food and air – cost $22,500 (£17,500) per astronaut each day.

Nasa will get around $35,000 (£27,000) per night that a private astronaut spends on board the ISS.

A large bank balance won’t be enough either: you’ll have to pass Nasa’s rigorous health checks and training procedures.

As part of its “commercialization” of the ISS, Nasa will be making one space station port and utilities available for a private company to “attach a commercial module to”.

And it hopes that in the long-term, there will be lots of private space stations floating just above Earth.

“In the long-term, NASA’s goal is to become one of many customers purchasing services from independent, commercial and free-flying habitable destinations in low-Earth orbit,” NASA explained.

“A robust low-Earth orbit economy will need multiple commercial destinations, and NASA is partnering with industry to pursue dual paths to that objective that either go through the space station or directly to a free-flying destination.”

Whatever ends up going into space, it’s unlikely to get cheaper any time soon.

Even SpaceX charges $62million (£48.7million) to send commercial satellites into orbit with its relatively new Falcon 9 rocket.

And Axiom Space, a Houston-based company hoping to organize trips to the ISS, has pledged to charge $55 million (£43.2 million) for a 10-day trip to the ISS.

So why is NASA letting tourists travel to the ISS?

The main advantage seems to be keeping costs down, as the ISS is very expensive to run.

But it’s also about continuing to test space travel – to make it safer and cheaper for everyone.

“Market studies identified private astronaut missions to low-Earth orbit as a key element to demonstrate demand and reduce risk for future commercial destinations in low-Earth orbit,” NASA explained.

The long-term plan is to create space stations near Earth that can be used as stop-off points for deeper trips into space.

NASA hopes to set up several “lunar gateways” starting from 2028 that will float near the Moon, and could be used for crewed missions to Mars.

“The first Gateway is about the moon, but I think the second Gateway, being a deep-space transport, again using commercial and international partners, enables us to get to Mars,” said NASA top boss Jim Bridenstine, speaking last year.

“What we don’t want to do is go to the surface of the moon, prove that we can do it again, and then be done. We want to go to stay.

“And the Gateway, in my view – I’ve been convinced – enables us to take advantage of commercial and international partners in a more robust way so we are there to stay, it enables us to get to more parts of the moon than ever before, and it enables us to get to Mars.”

Stone block with mysterious 12,000-year-old engravings discovered at prehistoric hunting site

Archaeologists in France have uncovered a mysterious carved stone block at a prehistoric hunting site.

The stone was found during excavations at Angouleme in southwestern France.  A number of engravings have been carved into the sandstone, including horses, deer and an aurochs, an extinct species of wild cattle.

“The most visible engraving, that of a headless horse turned to the right, occupies half the surface,” according to a translated statement from French national archeological research organization Inrap. “The rump and the saddle follow the curves of the natural edge of the stone. Very fine incisions may suggest the coat”.

The area where the stone was found was used as a hunting site by the prehistoric Azilian culture. Other items discovered at the site include tools for stripping carcasses.

Experts think that the stone is about 12,000 years old. More research will be done to precisely date and gain more information from the artifact.

Other mysterious stones have been grabbing attention in France. A village in Brittany, for example, recently offered a reward to anyone who can decipher a strange inscription on a centuries-old rock.

Last year, archaeologists announced the discovery of 12,000-year-old cave drawings in Eastern France.

Archaeologists find rare writing, and then it vanishes

Archaeologists digging for ruins ahead of a new construction project in Jerusalem made an incredible discovery—that immediately began to vanish. During the last hours of a “salvage excavation” two months ago, the Israel Antiquities Authority stumbled upon a 2,000-year-old ritual bath when a stone suddenly disappeared into a black hole, reports Haaretz.

That hole turned out to be the remains of the bath, accessible by a stone staircase, which includes an anteroom with benches and a winepress. Carved into a natural stone cave, the bath itself wasn’t so unusual, but the graffiti that covered the plaster walls was.

Archaeologists were therefore horrified to find the Aramaic inscriptions and paintings in mud and soot, dating to the Second Temple era from 530BC to 70AD, per Discovery News, disappearing within hours of their discovery.

“The wall paintings are so sensitive that their exposure to the air causes damage to them,” the IAA says, per Ynetnews. Crews quickly removed and sealed the plaster so the graffiti, along with a few carvings, can be preserved.

Archaeologists say the Aramaic inscriptions are particularly special as few such writings have been found, though the script is hardly legible now. They guess at a few words, including what translates to “served” and the name “Cohen.” Still, the inscriptions back up the argument that Aramaic was commonly used at the time and perhaps even the language of Jesus.

The plaster also holds drawings of a boat, palm trees and other plants, and what might be a menorah—portrayals of which were then considered taboo. An IAA rep says graffiti in baths may have been “common, but not usually preserved.” (Another recent find: the remnants of a “treasured landmark” destroyed by the Nazis.)

Climate scientists criticize government paper that erases ‘pause’ in warming

Until last week, government data on climate change indicated that the Earth has warmed over the last century, but that the warming slowed dramatically and even stopped at points over the last 17 years.

But a paper released May 28 by researchers at the National Oceanic and Atmospheric Administration has readjusted the data in a way that makes the reduction in warming disappear, indicating a steady increase in temperature instead. But the study’s readjusted data conflict with many other climate measurements, including data taken by satellites, and some climate scientists aren’t buying the new claim.

“While I’m sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don’t regard it as a particularly useful contribution to our scientific understanding of what is going on,” Judith Curry, a climate science professor at Georgia Tech, wrote in a response to the study.

And in an interview, Curry told FoxNews.com that that the adjusted data doesn’t match other independent measures of temperature.

“The new NOAA dataset disagrees with a UK dataset, which is generally regarded as the gold standard for global sea surface temperature datasets,” she said. “The new dataset also disagrees with ARGO buoys and satellite analyses.”

The NOAA paper, produced by a team of researchers led by Tom Karl, director of the agency’s National Climatic Data Center, found most of its new warming trend by adjusting past measurements of sea temperatures.

 Global ocean temperatures are estimated both by thousands of commercial ships, which record the temperature of the water entering their engines, and by thousands of buoys – floatation devices that sit in the water for years.

The buoys tend to get cooler temperature readings than the ships, likely because ships’ engines warm the water. Meanwhile, in recent years, buoys have become increasingly common. The result, Karl says, is that even if the world’s oceans are warming, the unadjusted data may show it not to be warming because more and more buoys are being used instead of ships. So Karl’s team adjusted the buoy data to make them line up with the ship data. They also double-checked their work by making sure that the readjusted buoy readings matched ships’ recordings of nighttime air temperatures.

The paper came out last week, and there has not been time for skeptical scientists to independently check the adjustments, but some are questioning it because of how much the adjusted data vary from other independent measurements.

First, it disagrees with the readings of more than 3,000 “ARGO buoys,” which are specifically designed to float around the ocean and measure temperature. Some scientists view their data as the most reliable.

The ARGO buoy data do not show much warming in surface temperature since they were introduced in 2003. But Karl’s team left them out of their analysis, saying that they have multiple issues, including lack of measurements near the Arctic.

In an email, Karl told FoxNews.com that the ARGO buoy readings may be added to his data “if scientific methods can be found to line up these two types of temperatures together … (of course after correcting the systematic offsets) … This is part of the cumulative and progressive scientific process.”

Karl’s study also clashes with satellite measurements. Since 1979, NOAA satellites have estimated the temperature of Earth’s atmosphere. They show almost no warming in recent years and closely match the surface data before Karl’s adjustments.

The satellite data is compiled by two separate sets of researchers, whose results match each other closely. One team that compiles the data includes Climate Professors John Christy and Roy Spencer at the University of Alabama in Huntsville, both of whom question Karl’s adjusted data.

“The study is one more example that you can get any answer you want when the thermometer data errors are larger than the global warming signal you are looking for,” Spencer told FoxNews.com.

“We believe the satellite measurements since 1979 provide a more robust measure of global temperatures, and both satellite research groups see virtually the same pause in global temperatures for the last 18 years,” he said.

Karl said satellite data also have issues, including “orbital decay, diurnal sampling, instrument calibration target temperatures and more.”

Spencer said he agreed that those are issues, but they are less problematic than using data from thousands of ships and buoys. He added that there are a couple of satellites monitoring temperature at any given time, and that they are used to check each other.

Skeptics say there are yet more measurements, including those coming from balloon data, that line up with existing data more than with Karl’s newly adjusted data. They also note that even with Karl’s adjustments, the warming trend he finds over the last 17 years is below what U.N. models had predicted.

Some climate scientists applaud Karl’s adjustments and say they debunk the idea that the Earth has stopped warming.

“[This] points out just how small and fragile a notion that was,” Peter Frumhoff, director of science & policy at the Union of Concerned Scientists, told FoxNews.com

Asked about the contradiction with satellite data, he said he trusted the new paper.

“I trust the process of legitimate scientific peer review that this paper has undergone, as well as the care that its authors bring to their respected work,” he said, adding that, “the faux debate over a so-called ‘hiatus’ has been an unfortunate diversion from meaningful dialogue about how best to address the broadly recognized serious problem of climate change.”

But skeptics say Karl’s adjusted data is the outlier that conflicts with everything else. “Color me ‘unconvinced’,” Curry wrote.

1.8-million-year-old skull shakes mankind’s family tree

1.8-million-year-old skull shakes mankind’s family tree

  • Dmanisi skulls 1-5 show remarkable differences — and remarkable similarities. (M. PONCE DE LEÓN AND CH. ZOLLIKOFER, UNIVERSITY OF ZURICH, SWITZERLAND)

Some had protruding foreheads, others had short, squashed faces. Some had enormous jaw muscles and big teeth, while others had enormous heads to hold bigger brains. 

They had one thing in common, however: They were family — our ancient family, that is, from around 2 million years ago.

The world’s first completely preserved adult hominid skull from the early Pleistocene era looks surprisingly different from other skulls of the same era, yielding a remarkable insight: Man’s early ancestors appeared as physically diverse as humans do today, researchers said, and our family tree has perhaps fewer branches than today’s schoolbooks teach.

“It’s a really extraordinary find,” said paleoanthropologist Marcia S. Ponce de Leon in a press conference Wednesday announcing the findings. “For the first time, we can see a population from the early Pleistocene. We only had individuals before. Now we can make comparisons and see the range of variation.”

‘The five Dmanisi individuals are no more different from each other than any five modern humans or chimpanzees.’

– Neurobiologist Christoph Zollikofer from the Anthropological Institute and Museum in Zurich 

The skull in question is a complete, 1.8-million-year-old ancestor of man, found in Dmanisi, Georgia, in Eastern Europe. The fifth such skull from the region spanning a period of a few centuries, it’s known at present only as “Skull 5” — it hasn’t received a clever name yet like Lucy, the remarkable African skeleton found in the 70s and dating back 3.4 million years. (Lucy is anAustralopithecus afarensis, an even more distant relative of modern man.)

The rarity of such artifacts makes studying them a challenge; other skulls from about 2 million years ago showed wide enough differences in shape that scientists have so far labeled them different species entirely: Homo habilis and Homo rudolfensis, for example.

Skull 5 is different, different even than the four other skulls found at Dmanisi. It was found in 2005, and ultimately matched to a jaw found in 2000 to make a complete skull. But after eight years of study, scientists on Thursday published a paper in the journal Sciencerevealing that Skull 5 is simply not that different from others.

“The five Dmanisi individuals are no more different from each other than any five modern humans or chimpanzees,” said neurobiologist Christoph Zollikofer, a co-author of the paper with Ponce de Leon, both of whom work at the Anthropological Institute and Museum in Zurich, Switzerland.

“The brain case is very small — around a third of [the size of] modern humans at 546 cubic centimeters — and at the same time, we have the face that is quite large, and the jaws are quite massive, and the teeth are big and large,” she explained.

“This is a strange combination of features that we didn’t know before in early homo,” Ponce de Leon said. Such a skull shape was previously unseen, yet it was actually more similar to the others than it was different, the team found.

“Dmanisi is the first site where we can really look into and quantify variation in fossil hominid population,” Zollikofer said.

The site itself is an intriguing location that David Lordkipanidze from the Georgian National Museum Tbilisi, Georgia — a third paper author — described as “a medieval city on a hilltop.”

When these early hominids were walking around, 2 million years ago, the climate was temperate and relatively humid, he said. The site was a short distance from water, situated on the remants of a lava flow. Beyond just skulls, some scattered evidence of daily life remained too, as well as a wide variety of plant and animal remains spread over an area spanning about 1.2 acres.

“We found stone tools and cut marks on animal bones, which indicate that hominids were actively involved in meat-processing,” Lordkipanidze said. One of the skulls had a wound on its cheek too, which could have come from a fight following an argument or something as simple as an injury in a fall.

“This was a place with stiff competition between carnivores and hominids. We found almost a hundred carnivores and it seems they were fighting for the carcasses. Fortunately for the hominids — and fortunately for us — they were not always successful.”

But the real revelation is the variation among these ancient creatures, who had long legs and short arms and smaller brains than us. What other secrets does this mountain range hold?

“We still have a lot to discover,” he said.
