Massive Solar Flare Could Cause Global Chaos in 2013

The sun’s solar flares could endanger human life by interfering with high-tech systems such as satellites and power grids.

A massive solar flare could paralyze Earth in 2013, causing blackouts and wrecking satellite communications, a conference heard yesterday. Nasa has warned that a peak in the sun’s magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels.

Researchers Find Link Between Solar Flares and Radioactive Elements on Earth

Large solar flare recorded by the SOHO/EIT telescope using UV light. 

When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics.

Fascinating Video of Our Terrifyingly Crowded Solar System

crowded solar system

This image shows the number of asteroids in the solar system currently (2010).

It’s not just our country that’s a little over-crowded – our whole solar system is too.  A fascinating color-coded video illustrates how we have become increasingly aware of the number of asteroids flying close to Earth as telescopes improve. (Pics and video)

Artists Video Charts Every Nuclear Explosion on Earth Since 1945

 

This is a video that starts slow, but around 3 minutes in… well. It shows every nuclear bomb explosion on the Earth from 1945 — the US test before the bombs dropped on Japan — to 1998, when India and Pakistan joined the madness.

Earth’s Upper Atmosphere Suffers Record Breaking Collapse

NASA is puzzled over the record breaking atmopheric collapse

The Earth’s upper atmosphere has had a record breaking collapse, one that has scientists both puzzled and worried, NASA announced Thursday.

The collapse occurred during a period of low solar activity known as a “solar minimum.” During a solar minimum, sunspots and solar flare activity heavily diminish. Since the date range of a solar minimum expands over a 12-month period, it can take up to 6 months to identify one.

This collapse occurred during the 2008-2009 solar minimum. While these minimums are known to cool and contract the thermosphere, this collapse was 3-times greater than low solar activity could explain…
