The shipwreck of the barge “Northern Light” was found about 2.5 miles (4 kilometers) southeast of Key Largo’s Elbow Reef in the Florida Keys at a depth of 190 feet (57.9 meters). The ship was built in 1888 as a freighter by Globe Iron Works of Cleveland, Ohio, but was converted into a barge in 1927. It’s believed that “Northern Light” sank in 1930 after it struck a floating object during a severe storm.

NOAA diver John Brooks inspects the remains of the vessel “USS MACAW” located among the reefs of Midway Island within the Northwestern Hawaiian Islands. The shipwreck serves as a reminder of the valuable contributions of the Naval Air Facility at Midway during World War II, and is part of Hawaii’s Papahanaumokuakea (Northwestern Hawaiian Islands) Marine National Monument.

Also located within Hawaii’s Papahanaumokuakea Marine National Monument, the “Hoei Maru” shipwreck rests at the bottom of Kure Atoll — the most remote of the Northwestern Hawaiian Islands. The “Hoei Maru” is one of the vessels shipwrecked on the small island’s surrounding reefs.

The “Paul Palmer” was built in 1902 and operated as a schooner in the New England coal trade. In June 1913, a fire broke out on the ship and the crew abandoned the vessel. Damage from the blaze caused “Paul Palmer” to sink to its final resting place at the bottom of the mouth of Massachusetts Bay, an area now known as the Stellwagen Bank National Marine Sanctuary. The above photo of the wreck shows fishing nets tangled in its partially buried remains.

Another ship located at Hawaii’s Kure Atoll reef, the “Dunnottar Castle” was a 258-foot (79-meter) cargo ship that was built in 1874 in Scotland. It was making its way from Sydney, Australia, to Wilmington, Calif., with a load of coal when it struck a reef and sank in July 1886. The wreck was initially explored by marine archaeologists in 2006. Although it has become flattened over time, the ship miraculously remained largely intact. Its ruins, including an iron hull, steel yards, masts and anchors, are inhabited by fish, clams and shrimp, and some portions of the ship are covered in coral.

Built in Northern Ireland in 1909, the “RMS Titanic” was also known as the “unsinkable ship,” because it had a double-bottom hull divided into 16 compartments that were presumed to be watertight. The 882.5-foot-long (268.9 meters) craft sank in April 1912 after it struck an iceberg off southern Newfoundland, and now rests on the ocean floor at a depth of 12,460 feet (3.7 kilometers).

19th-Century Shipwrecks Discovered Off Israel’s Coast

19th-Century Shipwrecks Discovered Off Israel’s Coast

Archaeologists have discovered four 19th-century warships, and possibly the remains of an ancient Greek harbor, off the coast of Israel.

The fleet was found at the ancient port of Akko, one of the major ports of the Mediterranean during the Hellenistic period from 300 B.C. to 100 B.C. The new discoveries could point to even more ancient, elusive shipwrecks.

“I’m very interested in finding a well-preserved example of an ancient multi-decked warship from the Hellenistic age,” study author Bridget Buxton, an archaeologist from the University of Rhode Island, said in a statement. “These ships were incredible pieces of technology, but we don’t know much about their design, because no hulls have been found. However, a combination of unusual environmental and historical factors leads us to believe we have a chance of finding the remains of one of these ships off the northern coast of Israel.”

The team found the four warships in 2011 using sound waves to probe beneath the ocean floor off the coast of Akko in northern Israel. The city has been a busy port since antiquity. After storms briefly washed away some of the sediment burying the ships, the Israeli Antiquities Authority peeked into one of the 105-foot (32-meter)-long ships. Sediment has since reburied the fleet. Wood from the ship came from Turkey, laboratory analysis showed.

The researchers believe the ships, once part of an Egyptian fleet, sank during the Egyptian Ottoman war when Admiral Osman Nurredin Bey attempted to retake the city of Akko in 1831.

In the process of excavating in the area, the team also found the remains of a ship shed that was possibly used to bring in warships during the Hellenistic period. At the site, they found remnants of Hellenistic stonework, ancient pottery, mooring materials and a stone quay. These fragments suggest a much older, ancient Greek port may lie beneath the seafloor — along with even more ancient shipwrecks.

“We’ve got fragmentary historic records for this area in the Hellenistic period, and now we’ve found a very important feature from the ancient harbor. Ancient shipwrecks are another piece of the puzzle that will help us to rewrite the story of this region at a critical time in Mediterranean history,” Buxton said in a statement.

The findings were presented at the annual meeting of the American Schools of Oriental Research on Nov. 15 and 17 in Chicago.

A world map of average life expectancy by country. How does your nation rank?

A world map of average life expectancy by country. How does your nation rank?

Robert T. Gonzalez

Here now to provide a some perspective on the matter of mortality is a variegated patchwork comprising 188 of the world’s countries, with each nation color-coded in accordance with the average life expectancy of its citizens.

Click here for a hi-res version of the map up top, and here for an interactive one (the applet also allows for mapping by gender).

Just for fun, we’ve included the top twenty-five countries — as ranked by the CIA World Factbook’s 2012 estimates — here. Looking for America? Don’t bother. Depending on the data source, the U.S. usually comes in somewhere between 29th and 50th :

This entry contains the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. The entry includes total population as well as themale and female components. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.

How space-based solar power will solve all our energy needs

How space-based solar power will solve all our energy needs

 How space-based solar power will solve all our energy needs

Humanity’s demand for energy is growing at an astonishing rate. Combine this with an ever-dwindling supply of fossil fuels, and it becomes painfully clear that something innovative and powerful is required. There’s one high-tech proposal that holds tremendous promise — an idea that has been around since the late 1960s. Here’s how space-based solar power will eventually solve all our energy needs.

Humans needs more power

Assuming that economic progress and globalization continues at its current pace, we’ll need to produce twice the amount of energy that’s consumed today by the 2030s — what will reach a monumental 220 trillion kiloWatt hours per year. And by the end of the century, we’ll need four times the current rate of consumption.

 

Just as importantly, we’re also going to have to kick the fossil fuel habit — and not only because it’ll eventually run out. Rising CO2 emissions are wreaking havoc on the Earth’s atmosphere, what’s creating environmentally deleterious side-effects at a rate faster than expected.

Moreover, if greenhouse gases are to be brought under control over the course of the next several decades, we’ll need to get upwards of 90% of all our energy from either renewable or nuclear sources.

While there are a number of proposals on the table for how we might be able to meet these challenges, none really appear to be truly viable.

Except for solar powered satellites.

Obvious benefits

A closer look at a space-based solution yields a lengthy list of advantages.

Solar powered satellites don’t produce any greenhouse gases, nor do they take up valuable real estate on Earth. Once the initial costs are met, they would be relatively cheap to maintain; the solar modules used for generating solar energy have a long service life, not to mention the astounding ROI that would come from a virtually unlimited energy source.

Additionally, they’re not constrained by night/day cycles, the weather, or the changing seasons. And indeed, they would be much more efficient than any kind of ground-based station. The collection of solar energy in space is seven times greater per unit area than on the surface of the planet. Moreover, the amount of solar energy available up there is staggering — on the order of billions of times greater than what we draw today; the Earth receives only one part in 2.3 billion of the Sun’s output. The potential for scalability is enormous, to say the least.

Solar powered satellites won’t be prone to terrorist attacks and they’ll reduce geopolitical pressure for oil. According to futurist Keith Henson, space-based solar could be used to power vehicles, like electric cars, or by enabling the production of synthetic fuels — which at a penny per kiloWatt hour would result in gasoline that costs one dollar a gallon.

At the same time, space-based solar would provide true energy independence for those nations who choose to implement it. And on top of that, the energy could be exported to virtually anywhere in the world; it would be especially valuable for isolated areas of the globe, including Africa and India.

Lastly, space-based solar power would also yield tremendous benefits to human and robotic space exploration, including the powering of off-planet colonies on the Moon, Mars, and space stations. It could also serve as the first seed in the development of a Dyson Sphere — a massive array of solar collectors that would completely envelope the sun at a distance of about 1 AU.

How it’s going to work

Back in the late 1960s, Peter Glaser proposed the idea of solar powered satellites (SPS), what he envisioned as space-based photovoltaics that could transfer energy wirelessly back down to Earth. His design called for a large platform positioned in space in a high Earth orbit that would continuously collect and convert solar energy into electricity. In turn, that power would be used to drive a wireless power transmission (WPT) that beams the solar energy to receiving stations on Earth — what would be comprised of massive receiving dishes.

A number of visionaries have updated Glaser’s vision to include the use of a microwave wireless power transmitter. This would involve large discrete structures (like a solar array and transmitter) that would have to be assembled in space. SPS systems could also include a modular electric/diode array laser WPT concept, involving self-assembling solar power-laser-thermal modules. Other designs call for an extremely modular microwave WPT SPS “sandwich structure” concept, requiring a significant number of small solar power-microwave-thermal modules that would be robotically assembled on orbit.

But to make it happen, we’ll need to develop low-cost, environmentally-friendly launch vehicles. Eventually we’ll send the materials up in a space elevator, but until then we’ll have to come up with something more efficient. Thankfully, SpaceX and other private firms are already working on more efficient launch solutions.

Additionally, we’ll require large scale construction and operations stations in orbit — space-based workplaces that would be more complex, larger, and more energy-demanding than the ISS. They would allow for the production of large, simple panels, that are easy to assemble and consist of many identical parts. Eventually, it may be possible to construct an entire flotilla of these solar collectors using materials extracted from asteroids.

Design proposals

As word gets out about the potential for SPS, and as the technology catches up to the idea, a number of design proposals have been put forth; this isn’t just idle speculation anymore — it’s something that’s just about ready for prime-time.

For example, there’s SPS-ALPHA (Solar Power Satellite via Arbitrarily Large PHased Array) which is being developed by NASA’s John Mankins. Using a “biomimetic” approach, the project calls for huge platforms constructed from tens of thousands of small elements that could deliver tens to thousands of megawatts via wireless power transmission.

It would do this by using a large array of individually controlled thin-film mirrors outfitted on the curved surface of a satellite. These adjustable mirrors would intercept and redirect incoming sunlight toward photovoltaic cells affixed to the backside of the solar power satellite’s large array. The Earth-pointing side of the array would be tiled with a collection of microwave-power transmission panels that generate the coherent, low-intensity beam of radio frequency energy and transmits that energy to Earth.

And what’s particularly cool about this concept is that it would enable the construction of a solar-power satellite that can be assembled entirely from individual system elements that weigh no more than 110 to 440 pounds (50 to 200 kilograms), allowing all pieces to be mass produced at low cost.

There’s also Japan’s JAXA’s SBSP System. The Japanese space agency want to get a prototype up and running by 2020, and a fully operational system by 2030. Their system is designed to run in a stationary orbit about 22,400 miles above the equator where it will absorb the sunlight with chromium-enhanced solar cells. The SBSP System will transmit energy to Earth using laser beams at about 42% solar-to-laser energy efficiency. Each satellite will beam the energy to a 1.8-mile wide receiving station that’ll produce one gigawatt of electricity — what’s enough to power 500,000 homes.

Other examples include the Sun Tower, the Dyson-Harrop Satellite (which would harness solarwind power), Solar Disc, and the European Sail Tower SPS.

Timelines

SPS systems have been discussed since the 1970s and have been reviewed periodically by various stakeholders in United States and elsewhere — but the idea has never been seen as something that’s cost effective or technologically feasible. These sentiments are changing, however.

Last year, the International Academy of Astronautics published an exhaustive reportlauding the benefits of space-based solar power, urging the international community to take the prospect seriously. The report contained over a dozen recommendations on how to get started, while predicting that space solar power will be technically feasible within 10 to 20 years using technologies thatalready exist.

The authors also noted that the project would be economically viable in the next several decades, but under specific conditions having to do with future energy markets and the willingness of governments to get started (what could be motivated by environmental concerns).

Additionally, flight experiments will be required, as will be the ironing-out of any policy or regulatory issues — what could definitely take some time. Needless to say, some groups and individuals may take great exception to the idea of having microwaves and laser beams shooting down onto the Earth’s surface — not to mention the nightmarish potential for the weaponization of this technology.

And in terms of expense, the IAA proposed a cost-sharing scheme in which nations would work together to bring the price down — what could cost as much as a trillion dollars.

But given the incredible benefits — not to mention the tremendous need — it’s a no-brainer that this needs to happen.

An absolutely incredible raw image of Saturn’s swirling north pole

Jason Major – Universe Today

Ok, are you ready for this? I know… WOW.

This swirling maelstrom of clouds is what was seen over Saturn’s north pole yesterday, November 27, by NASA’s Cassini spacecraft. This is a raw image, acquired in polarized light, from a distance of 238,045 miles (383,097 kilometers)… all I did was remove some of the hot pixels that are commonly found on Cassini images taken with longer exposures.

Again… WOW.

My attempt at a color composite can be seen below, plus another treat.

It’s rough, and a little muddy because the clouds were moving between image channels (not to mention the blue channel image was rather underexposed) but here’s a color-composite of the same feature, made from images taken from a slightly different perspective:

An absolutely incredible raw image of Saturn’s swirling north pole

Pretty darn cool… Cassini does it yet again!

The images above show an approximately 3,000-4,000-km-wide cyclone above Saturn’s north pole. Saturn is also known to have a long-lived hexagonal jet stream feature around its north pole as well, but that is not shown in those images as it runs along a lower latitude. Instead, you can see that HERE:

 

 

Captured with wider angle in this image the hexagon structure can be made out as well as the vortex, which sits at the center just over the pole. Saturn’s hexagon is about 25,000 km (15,500 miles) in diameter… large enough to fit almost four Earths inside. This image was also acquired today.

An RGB composite of this feature is below:

 

 

It’s been a few years since we’ve gotten such a good look at Saturn’s north pole… thanks to Cassini’s new orbital trajectory, which is taking it high above the ring plane and poles of Saturn, we now have the opportunity to view the gas giant’s dynamic upper latitudes again. I’m sure this is just a taste of what’s to come!

Saturn’s moons could comprise “a veritable arcade” of Pac-Men

Saturn’s moons could comprise “a veritable arcade” of Pac-Men

Astronomers now know that the Saturnian system has not one, but two ”Pac-Man” moons — and there could be many, many more.

Back in 2010, infrared heat maps of Mimas (also known as Saturn’s “Death Star” moon, for reasons that should be fully armed, operational and obvious), gathered by NASA’s Cassini spacecraft, revealed a Pac-Man shaped heat signature on its surface (pictured up top and below, on the left). Now, Cassini has returned evidence that Saturn’s icy moon Tethys is covered in a similar pattern.

Via NASA:

Scientists theorize that the Pac-Man thermal shape on the Saturnian moons occurs because of the way high-energy electrons bombard low latitudes on the side of the moon that faces forward as it orbits around Saturn. The bombardment turns that part of the fluffy surface into hard-packed ice. As a result, the altered surface does not heat as rapidly in the sunshine or cool down as quickly at night as the rest of the surface, similar to how a boardwalk at the beach feels cooler during the day but warmer at night than the nearby sand. Finding another Pac-Man on Tethys confirms that high-energy electrons can dramatically alter the surface of an icy moon.

Saturn's moons could comprise "a veritable arcade" of Pac-MenIt also suggests that moons with this heat signature may be more common than we realized.

“Finding a second Pac-Man in the Saturn system tells us that the processes creating these Pac-Men are more widespread than previously thought,” said Carly Howett, the lead author of the paper describing the so-called “thermal anomaly,” published in the latest issue of the journalIcarus.

“The Saturn system – and even the Jupiter system – could turn out to be a veritable arcade of these characters.”
