The moon formed much later than thought, but new questions arise

A new massive computer model that simulates the formation of the solar system from its early days when all it used to comprise was a huge disk of matter to present day shows that Earth’s moon formed some 65 million years later than previous estimates led us to believe. The method provides a new way […]

NASA Radar demonstrates ability to foresee sinkholes

New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La. that year. Researchers believe that they can use this type of data, usually routine gathered, to foresee at least some of the sinkholes. I’ve written a […]

Evidence of granite found on Mars - Red Planet geology more complex than previously thought

Geologists have now found the most compelling evidence of granites on Mars – something which prompts more complex theories about the geology and tectonic activity on the Red Planet. Granites and basalts Granites are igneous rocks, pretty common on the surface of Earth. It is often called a ‘felsic’ (white rock) – because it is […]

Mobile US seismic array maps American mantle

A laudable, ambitious initiative is nearing fruition: the US$90-million Transportable Array, a moveable grid of seismometers that blankets America. Since 2004, the set of 400 seismometers, loaded on trucks, have gradually marched, from the Pacific coast across the Rocky Mountains and the Great Plains and is finally reaching the eastern coastline. Whenever they arrive at […]

Insects trapped in amber offer a precious glimpse on prehistoric bugs

Amber is not very common, but you can’t say it’s really uncommon either. Bugs in amber – that’s rare, but a huge “stash” such as the one that was found in India – that’s really something out of this world. The bug “collection” that was unearthed seems to suggest that the Indian continent was not […]

Meet the horniest dinosaur ever

Fossil hunters have recently unearthed the fossil remains of a species that can easily claim the title of the horniest dinosaur ever to be found. Kosmoceratops lived some 76 million years ago, in the warm and wet swamps of (what is today) Utah; but what’s really fascinating about him is the fact that he has […]

8 surreal natural landscapes

The Wave, Arizona The Wave is an astonishing sandstone formation that fascinates photographers and attracts numerous hikers every year.

Tsunami […]

Danube delta holds answers to 'Noah's flood' debate

It seems science and creationism are just taking sides and throwing rocks at each other; recently, they’ve taken things to a whole new level, each bringing out more or less relevant arguments to support their ideas; of course, the juiciest discussions are focused on the Bible: is it or not true, does it refer to […]

Mineral Kingdom Co-evolved With Life

Evolution isn’t just for living organisms, as scientists the Carnegie Institution found. They found that more than 3000 of the 4000+ minerals that exist can be linked more or less directly to biological life. This finding could have a crucial importance for scientists that are searching for life on other planets. Robert Hazen and Dominic […]

Opals on Mars hint at planet's wet past

As a proud student in geophysics, I can tell you that opal is hydrated silicon dioxide mineral with many astounding properties, but it’s also water hydrated. Since water hydrated minerals have been found on Mars we are led to the logic conclusion that when these minerals was formed, there was water on Mars. Opals have […]

Report shows California has 99% chances of big earthquake in 30 years

I’m not fond of alarmist theories or “bad things are happening, fast” attitude, but… bad things are just going to happen soon in California. The likelihood of a major quake of magnitude 7.5 or greater in the next 30 years is 46%-and such a quake is most likely to occur in the southern […]
