Glikson, et al., (2016) report that the Archean rock record contains 17 asteroid impact ejecta units that represent the terrestrial vestiges of an extended late heavy bombardment (LHB). Correlated impact ejecta units include 3472 to 3470 Ma impact spherule layers in the Barberton Greenstone Belt, Kaapvaal Craton, South Africa, and the Pilbara Craton, Western Australia, and several ejecta units dated between 3250 and 3220 Ma and between 2630 and 2480 Ma (by others).

This paper reports the discovery and investigation of a new impact ejecta unit within the Marble Bar Chert Member (MBC... More →

John Brandenburg, Ph.D., was involved in the Clementine Mission to the Moon, which was part of a joint space project between the Ballistic Missile Defense Organization (BMDO) and NASA. The mission discovered water at the Moon poles in 1994. He was the deputy manager of that mission. It is noteworthy to mention that the Russian government recently called for an international investigation into the U.S. moon landings regarding missing artifacts (lunar rocks) and the disappearance of film footage.

According to Brandenburg, it was the Clementine Mission, a photo reconnaissance mission,... More →

Since 1929, more than 10,000 relics, dating between 5,000 and 3,000 years ago have been unearthed in the city Sanxingdui Ruins. The excavations have yielded some of the most significant Chinese archaeological discoveries of the 20th century.

Archaeologists around the world were excited by the unearthing of large palatial remains in 1980, the remnants of eastern, western and southern walls in 1984 and the discovery of two large sacrificial pits in 1986.

Archaeologists have been left wondering what the purpose of the objects was and how such an ancient culture, at the very ... More →

Paul Guyett reports that meteorite impacts can produce more than craters on Earth, they can also spark volcanic activity that shapes its surface and climate by bringing up material from depth. That is the finding of an international team, led by geochemists from Trinity College Dublin, who discovered that large impacts can be followed by intense, long-lived, and explosive volcanic eruptions.

The team studied rocks filling one of the largest preserved impact structures on the planet, located in Sudbury (Ontario, Canada). The bolide hit Earth here 1.85 billion years ago and excavated ... More →

A new discovery of an extremely rare mineral, called reidite, from a layer of rock in the North West Highlands of Scotland may seem insignificant on first glance. But this occurrence of reidite has major implications for understanding the early evolution of our solar system. To comprehend the significance of these small specs of reidite, we must first consider the moon.

The dating of lunar samples collected during the Apollo missions tells us that many of the impacts formed around 3.9 billion years ago, which was relatively early in the evolution of our 4.6 billion year old solar sy... More →

Amanda Koose reports that Mars has a history of offering up unusual formations for humans to marvel at, speculate about and scratch their heads over. For example, the face on Mars and more recently a jelly doughnut-shaped form and an object vaguely shaped like a human femur bone. The latest find is a formation that looks a bit like a deformed waffle.

An image captured by the Mars Reconnaissance Orbiter looked down onto what NASA describes as an enigmatic landform. The 1.2-mile wide feature is circular and sits in the Athabasca region of Mars, the location of some of the youngest lav... More →

Duncan Forgan reports that what you might not know is that the Moon is not the only natural satellite of the Earth. As recently as 1997, his group discovered that another body, 3753 Cruithne, is what is called a quasi-orbital satellite of Earth. This simply means that Cruithne does not loop around the Earth in a nice ellipse in the same way as the moon, or indeed the artificial satellites we loft into orbit. Instead, Cruithne scuttles around the inner solar system in what is called a horseshoe orbit.

So Cruithne is our second moon. It is only about five kilometres across, which is... More →

A massive asteroid that struck South Australia during a glacial cold snap 590 million years ago may have triggered the evolution of Earths earliest complex organisms, Australian geologists reported. In 2010, researchers from the University of Adelaide argued that the Acraman asteroid impact coincided with an extensive glaciation period more than 500 million years ago and created ideal conditions for an explosion of complex organisms, known as the Ediacara biota.

The Ediacaran Period was characterized by the oldest definite multicellular organisms with tissues, and the most common ty... More →

Ohio's geologic history is remarkable for many earth-bound events, including volcanic eruptions, glaciation, earthquakes, and the profound effects of surface weathering and erosion. But Ohio also has been shaped by cosmic forces, namely meteorite impacts, both small and large. Such events are reflected by Ohio's geology but they also indicate much about the materials and processes that compose and shape other bodies in our solar system. The study of these bodies and materials from space and their geologic processes is called astrogeology. Specialties within astrogeology include the study of m... More →

Dr. Conca reported that he laughed out loud when he saw the segment on the QVC shopping network where host Shawn Killinger and designer Isaac Mizrahi argued over whether or not our Moon was a planet. Or a star. Or cheese.

Not because it was foolish, but because Shawn and Isaac did not realize their debate was genuine and ongoing amongst scientists. The cynical responses on other TV channels of course, the Moon is not a planet was also quite wrong, from HuffPost, Rachel Maddow. And the technically-correct but partial definition that the Moon is a natural satellite does not mean anyt... More →

Katrina Kramer reports that four new elements have just been added to the periodic table completing the 7th row of the table. But despite elements 113, 115 and 118 all being discovered in the early 2000s and 117 in 2010, there is still no sign of elements 119 and beyond. Why has no one created one of these new superheavyweights and when will chemists be able to start an eighth row on the periodic table?

Since Edwin McMillan and Philip Abelson synthesized the first transuranium element neptunium in 1940, a steady stream of new elements has filled the lower rows of the periodic table.... More →

Lee Billings reports that even a dwarf planet can harbor big surprises. Ever since it was discovered floating between Mars and Jupiter in 1801, Ceres has perplexed astronomers and defied easy categorization. Telescopic studies over the years showed it was roughly the size of Texas, with up to a third of its weight in water ... too small to be a true planet, too wet and icy to be an asteroid and too big and rocky to be a comet. Astronomers chalked up the Ceres oddities to its being a relic from an early, formative epoch of our solar system, when planets coalesced from many Ceres-like objects mo... More →

The red rain microbes, which caused red rain phenomenon in Kerala, India, exhibit many characteristics much different from conventional microorganisms. Previous study indicates that these microbes are possibly of extraterrestrial origin. Their ability to multiply at extreme high temperature of 300C and the unusual autofluorescence of their biomolecules are some of their extraordinary properties. Their molecular composition is yet to be identified. In this paper we report the growth pattern of these novel microbes at temperatures below 100C as a minimal approach to show their biological nature.... More →

Jennifer Hackett reports that last week the Internet was abuzz with rumors of a strange star that some suggested might host an extraterrestrial construction. Astronomers say that scenario is a slim possibility. A more likely explanation is that the weird star, called KIC 8462852, is orbited by a swarm of comets, which is a pretty interesting idea on its own. But either way, this intriguing star might never have been found.

Eva Botkin-Kowacki reports that two meteors slammed into the earth at the same time, about 458 million years ago, say scientists. Researchers have found two impact craters in Jamtland, Sweden, just under 10 miles from each other.

One crater stretches an impressive 4.7 miles wide. The other is a bit smaller, not quite reaching 2,300 feet across. Around 470 million years ago, two large asteroids collided in the asteroid belt between Mars and Jupiter, and many fragments were thrown off in new orbits. Many of these crashed on Earth, such as these two in Jamtland, said Erik Sturkell, pro... More →
