Sky Diamond Likely Evidence of Proto-Planet

Inside a meteorite that exploded above northern Sudan’s Nubian Desert are swaths of diamond which would have required pressures of 2.9 million lbs per square inch to form. Researchers have concluded that the most likely source is an early planet from the formation of our own solar system at least 4.55 billion years in the past.

… Researchers from Switzerland, France and Germany examined diamonds found inside the Almahata Sitta meteorite and concluded they were most likely formed by a proto-planet at least 4.55 billion years ago.

The diamonds in the meteorite, which crashed in Sudan’s Nubian Desert in October 2008, have tiny crystals inside them that would have required great pressure to form, said one of the study’s co-authors, Philippe Gillet.

“We demonstrate that these large diamonds cannot be the result of a shock but rather of growth that has taken place within a planet,” he told The Associated Press in a telephone interview from Switzerland.

Gillet, a planetary scientist at the Federal Institute of Technology in Lausanne, said researchers calculated a pressure of 200,000 bar (2.9 million psi) would be needed to form such diamonds, suggesting the mystery planet was as least as big as Mercury, possibly even Mars.

Scientists have long theorized that the early solar system once contained many more planets—some of which were likely little more than a mass of molten magma. One of these embryo planets—dubbed Theia—is believed to have slammed into a young Earth, ejecting a large amount of debris that later formed the moon.

“What we’re claiming here,” said Gillet, “is that we have in our hands a remnant of this first generation of planets that are missing today because they were destroyed or incorporated in a bigger planet.”

Addi Bischoff, a meteorite expert at the University of Muenster, Germany, said the methods used in the study were sound and the conclusion was plausible, but added that further evidence of sustained high pressure would be expected to be found in the minerals surrounding the diamonds.

Almahata Sitta meteorites are unique because they are the first known to come from a tracked asteroid. An SUV sized asteroid known as 2008 TC3 was discovered Oct 6, 2008 by an automated NASA tracking telescope and meteorites from it were located from the explosion when it entered our atmosphere.

The NASA-sponsored Catalina Sky Survey is itself interesting.

The Catalina Sky Survey (CSS) is a NASA funded project supported by the Near Earth Object Observation Program (NEOO) under the Planetary Defense Coordination Office (PDCO). We are based at the University of Arizona’s Lunar and Planetary Lab in Tucson, Arizona.  Our mission at CSS is fully dedicated to discover and track near-Earth objects (NEOs) in an effort to meet the congressional mandate to catalogue at least 90 percent of the estimated population of NEOs larger than 140 meters, some of which classify as potentially hazardous asteroids (PHAs) which pose an impact threat to Earth. Longstanding success of the project is attributable to our comprehensive sky coverage, continued development and application of innovative software and our NEO detection pipeline, and the inclusion of near real-time human attention to the

NEO discovery and follow-up process.

The project picked up a UFO in 2013 which generated a no-fly zone alert in 2015 as the unidentified object entered our atmosphere.

Space junk ‘UFO’ prompts no-fly zone

An unidentified flying object suspected to be an old rocket body is on a crash course for Earth, prompting a call for precautions even though it’s expected to burn up in the atmosphere. There’s an actual unidentified flying object on a collision course with Earth as I write this. It prompted officials in one part of the world to issue no-fly and no-fishing zones this week as a precaution.

However, rather than transporting our new alien overlords to enslave us before we even have a chance to see ” Star Wars: The Force Awakens,” this UFO is more likely a piece of man-made space junk about to go out in a literal blaze of glory.

The UFO in question was discovered by the Catalina Sky Survey in 2013 and labeled “WT1190F.” The WTF in the name is appropriate. Even today, with the object just hours away from putting on a potential light show as it burns up over the Indian Ocean off the coast of Sri Lanka, it has not been positively identified.

It did put on a show and as predicted impacted the Earth’s atmosphere on November 13, 2015 at 06:18 UTC south of Sri Lanka.

WT1190F had been orbiting Earth as a temporary satellite since mid 2009 (named as UWAIS), if not longer. While it has not been positively identified with any known artificial satellites, its estimated density of 0.1 g/cm³ was much lower than would be expected of a natural object as even water has a density of 1 g/cm³. Hence, European Space Agency astronomers have concluded that the object was likely a fuel tank of some sort.

Some say it was space debris from the trans-lunar injection stage of the 1998 Lunar Prospector mission, but we may never know.

Getting back to the space diamond, you may recall that a giant planet composed of at least 1/3rd diamond has been found in our own galaxy.

The alien planet, a so-called “super-Earth,” is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet’s mass and radius, and studying its host star’s composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates. At least a third of the planet’s mass is likely pure diamond.

There are indeed diamonds in the sky.
