Scientist Explains Why Mars is Red (and How it Could Happen On Earth, too)

surface of Mars

Mars is covered with a thin layer of radioactive substances including uranium, thorium and radioactive potassium.

Mars has not always been red. At least that is the theory proposed by a scientist who has discovered a reason as to how the red planet got its rosy color.

Much more ozone (in red) is shown over the Arctic in the left image than the right image.

Check out the stark difference between these two satellite images, taken on March 19, 2010 and March 19, 2011. The left image shows much more ozone (in red) over the Arctic than the right image. What’s happened?

If winds continue to pick up at the same rate, hurricanes could become far more damaging by the middle of the century. 

The world is getting breezier, according to a new study, which found a slow but steady increase in top wind speeds across the oceans over the last 23 years.

Earth is overdue a solar storm as the sun enters its most active period

 The world is overdue a ferocious ‘space storm’ that could knock out communications satellites, ground aircraft and trigger blackouts – causing hundreds of billions of pounds of damage, scientists say.

By 2050 Our Planet Could Be ‘Unrecognizable’

Earths city lights

This image of Earth’s city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS).

A growing, more affluent population competing for ever scarcer resources could make for an “unrecognizable” world by 2050, researchers warned at a major US science conference Sunday.

Astronauts Could One Day Reach Mars by Riding Asteroids

In 2005, Japan’s unmanned Hayabusa spacecraft (illustration) successfully landed on an asteroid.

Getting to Mars is going to involve building a huge spacecraft and loading it up with tons of fuel and radiation shielding. Unless, that is, we could just tag along with a spacecraft that’s already headed in that direction, like an asteroid.

Russian scientists held a meeting 14 months ago to look at launching an operation to knock the Apophis asteroid off course

An asteroid travelling at 23,000mph could crash into Earth on April 13, 2036 killing millions and causing global chaos, scientists claim.  In a plot line taken straight from a science-fiction film, astronomers in Russia are predicting that the 300-yard-wide Apophis will slam into the planet in 25 years’ time.

Red dwarf stars make up 80% of the stars in the universe.

Red dwarf stars are far more common than astronomers have believed — in fact, they may make up 80 percent of the star population, scientists said in a study on Wednesday that triples the number of stars in the universe.

NASA and DARPA Plan ‘Hundred-Year Starship’ to Leave Earth and Never Come Back

This Mars miner will probably never go home again.

If NASA ever gets a clear directive for interplanetary exploration, a new Hundred-Year Starship could be their version of the Mayflower. And like the first pilgrims, Martian explorers might set sail with the knowledge they would never return home.

Is Mining the Moon Vital to U.S. National Security?

mind-blowing-moon-base

Could the moon be mined for rare earth elements?

The seemingly barren moon may actually be a treasure-trove of priceless resources: a potentially bountiful, mineral-rich – yet untapped – cosmic quarry. Still, few see the moon as an alluring mining site, ripe for the picking of rare elements of strategic and national security importance.
