Huge Plasma Tsunamis Hitting Earth Explains Third Van Allen Belt

The dynamic relationship between Earth and the Sun two sides. The warmth from the Sun makes life on Earth possible, but the rest of the Sun's intense energy pummels the Earth, and could destroy all life, given the chance. But thanks to our magnetosphere, we are safe. The magnetosphere is our protective shield. It's created by the rotation of the molten outer core of the Earth, composed largely of iron and nickel. It absorbs and deflects plasma from the solar wind. The interactions between the ma

Yes, we've found another one

After the excitement of February when we (the LIGO Scientific Collaboration & Virgo Collaboration, or LVC for short) announced the first direct detection of a gravitational wave signal a lot of people having understandably been asking "Well, did you see any more?". The analysis performed for the announcement of the first detection (of the source called GW150914) used just over a month of data from the start of a longer observing run (that we called O1), which ran from the 12th September 2015

Mammals Were Already Flourishing When The Axe Fell On The Dinosaurs

It's an apocryphal image. The ignorant faces of the dinosaurs, roaring helplessly at their fate, and looking skyward as an asteroid plunged to Earth. And the sneaky, clever little mammals coming out of their hiding holes to take their rightful place. If you grew up reading about this version of things, you're not alone. The line of reasoning says that mammals were present during the dinosaur's reign, but their potential to thrive was suppressed by the dinosaurs, which were supremely evolved to do

Mars Stink To Be Duplicated For Earthbound Humans

Intellectual curiosity is a great gift. It's fulfilling to ponder the great questions of existence: Will the Universe die of heat death after it's expanded for billions and billions (and billions) more years? Is there something outside of our Universe? What's on the other side of a black hole?... and... What does Mars smell like? Seriously. What may seem to be a frivolous question at first is actually quite interesting once your intellectual curiosity is engaged. The Martian atmosphere itself is mu

Tutankhamun's Meteorite Blade

The spread of metallurgy in different civilizations is a keen point of interest for historians and archaeologists. It helps chart the rise and fall of different cultures. There are even names for the different ages corresponding to increasingly sophisticated metallurgical technologies: the Stone Age, the Bronze Age, and the Iron Age. But sometimes, a piece of evidence surfaces that doesn't fit our understanding of a civilization.[embed]https://www. youtube. com/watch?v=_XXxDhqqtr0&feature=youtu. be

New Einstein Ring' Discovered By Dark Energy Camera

... rare object called an Einstein Ring has been discovered by a team in the Stellar Populations group at the Instituto de Astrofísica de Canarias (IAC) in Spain. An Einstein Ring is a specific type of gravitational lensing. Einstein's Theory of General Relativity predicted the phenomena of gravitational lensing. Gravitational lensing tells us that instead of travelling in a straight line, light from a source can be bent by a massive object, like a black hole or a galaxy, which itself bends ...

Alien Minds Part III: The Octopus' Garden and the Country of the Blind

In our galaxy, there may be, at least, tens of billions of habitable planets, with conditions suitable for liquid water on their surfaces. There may be habitable moons as well. On an unknown number of those worlds, life may have arisen. On an unknown fraction of life-bearing worlds, life may have evolved into complex multicellular, sexually reproducing forms. During its habitable period, a world with complex life might produce hundreds of millions of evolutionary lineages. One or a few of

Alien Minds Part II: Do Aliens Think Big Brains are Sexy Too?

Nothing in biology makes sense, wrote the evolutionary biologist Theodosius Dobzhansky, except in the light of evolution. If we want to assess whether it is likely that technological civilizations have evolved on alien planets or moons, and what they might be like, the theory of evolution is our best guide. On May 18, 2016 the newly founded METI (Messaging to ExtraTerrestrial Intelligence) International hosted a workshop entitled 'The Intelligence of SETI: Cognition and Communicati
