NASA's MAVEN Reveals How Mars Became Dead Planet

Solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that could have supported life billions of years ago into a frigid desert world, according to new results from NASA's MAVEN (Mars Atmosphere and Volatile Evolution Mission) spacecraft led by the University of Colorado Boulder.

Ocean Microbes and How They Affect Our Atmosphere in the Age of Climate Change

That restorative sea breeze you enjoy on your vacation is more complex than most of us realize. Now, researchers from the Center for Aerosol Impacts on Climate and the Environment (CAICE) have demonstrated that microbes in seawater influence our climate, shaping the ways that sunlight enters the ocean as clouds form. The study recently presented to the American Chemical Society shows that it is the microbes in the seawater that control the way sea spray enters into the atmosphere, and everything that follows that.

Researchers Find How Acidified Oceans Have Become with Help of NASA and ESA Satellites

While many argue that the fight against greenhouse gases is long over, climatologists and ecologists continue to urge that the battle continues on. And while the culprits are all the same, the problems with these remnants of burning fossil fuels are taking on new problems. A topic of major research has developed from these changes and now researchers are quantify just how it will impact our world in the years to come.

Pushed to the Brink—Humans Put Earth in 'The Danger Zone'

With unprecedented levels of carbon dioxide in the atmosphere, widespread species extinction, habit destruction, and increased levels of nitrogen and phosphorous in the oceans courtesy of polluting fertilizers, the Earth is being pushed to the brink and could one day make it unsafe for the continuation of life. The rate at which humans are destroying the environment is entirely unprecedented, and with such a devastating effect unseen in the last 11,700 years, life is facing an uncertain future ahead.

Earth’s Warm Streak Could Peak in a Decade, If Policymakers Don’t Change

Speed up the models and cut down on your carbon footprints, because a bit of change today could spell better weather and a better Earth only a decade away. While climatologists and researchers across all of science have in recent years discussed the long-term goals of climate change and the effects of carbon emissions, a new study published today, Dec. 2, in the journal Environmental Research Letters reveals that reductions in carbon emissions today will help shape the planet’s atmosphere in as little as 10 years, versus the 30 to 50 year models used by researchers and policymakers until now.

Researchers Reveal Method for Magnetic Field Calculation of Exoplanets

Knowing the level of a planet’s magnetic field can be an important fact to know in the study of how they interact. But studying the fields of an exoplanet, outside of our solar system and orbiting a foreign star, can be a difficult task that researchers have not yet been able to achieve. Though in nearly two decades of looking past our solar system to investigate exoplanets, researchers have developed several methods to estimate magnetic fields at quite a distance.

Wildfires May Fill our Future as Climate Change Sparks Lightning

Anthropogenic climate change, caused by the actions and emissions put forth by humans, has been a major conversation starter in recent months. But new research released today in the journal Science says that we may be looking at a future filled with a few more sparks rather than just warmer summers and rising seas.

Siding Springs Comet Came in Close For a Martian Meteor Shower

Earlier last month, on Oct. 19, researchers from the world’s top space agencies were able to catch a glimpse at one of the rarest sights in space. Coming from the outer Oort Cloud, at the very edge of our solar system, young comet Siding Spring passed by Mars rather closely on its first orbit around the sun; giving Mars orbiters a show and quite a scare. But as it turns out new data collected from NASA’s satellites on the night of the event show that the best view may have in fact been from the red planet itself.

Explaining How Rare ‘Fallstreak Hole’ Appeared Down Under

People may not be too observant to what’s happening around them, or what strange things are happening above them in the cloudy skies, but when a “hole punch” cloud filled with rainbows appears just overhead it can definitely be a viral phenomenon.

NASA’s Spacecrafts ‘Duck And Cover’ Behind Mars as Comet Passes Through

It’s been a flyby anticipated for months, and one whose arrival sparked much commotion at NASA’s headquarters this past weekend. Hurtling through the night sky at nearly 125,000 miles per hour, Comet C/2013 A1 Siding Spring passed right by the planet Mars early Sunday afternoon, Oct. 19, coming in close contact with the Martian outer atmosphere at about 2:27pm ET.

On Droughts and Dust Bowls—California Looks Back to 1934

Recently accepted for publication by the journal Geophysical Research Letters, a journal of the American Geophysical Union, the research lead by NASA’s Goddard Institute for Space Studies analyzed the relative intensity and devastation caused by droughts since 1000 AD and found that though the 2014 summer in California was particularly out of the ordinary even in the driest of areas, it did not quite compare to the drought of 1934.
