Giant Martian Dust Storm Threatens Opportunity Rover

According to NASA, the weather event the rover faced in 2007 had an opacity level around 5.5. Interestingly enough, as nature often does, the current dust storm does have one positive effect for Opportunity: it lessens the degree to which Mars' temperatures plummet in the overnight hours as the dust absorbs heat and raises the ambient temperature surrounding Opportunity.

When Did Animals Leave Their First Footprint On Earth?

The research was published in Science Advances on June 6, 2018. Further, the footprints left behind by its multiple feet suggest that this sea-dwelling animal had paired appendages that raised its body above the ocean floor. The tracks are only a few millimeters in diameter and dot the soft gray limestone found in the Yangtze Gorges region of China . While the researchers are unable to identify the animal behind the footprints, there are three types of living animals with paired ... Read More »

Aletta becomes first hurricane of eastern Pacific season


With wind speeds that can top more than 180 miles per hour, hurricanes are not usually thought of as slow. Kossin argues that the slow-down is caused by global warming, which is both increasing rainfall and decreasing wind currents. Adding last year's storms would have made the slowdown a bit more prominent, he said. Experts believe that continued global warming will increase the severity of tropical storms, but they also believe this anthropogenic warming will increase rainfall. Read More »

NASA launches new crew to the International Space Station


It will be the second flight for German Alexander Gerst, and the first for the other astronauts, American Serena M. Auñón-Chancellor from Indianapolis and Sergey Prokopyev of Roscosmos.

Planet Nine could be a cluster of asteroids sending comets Earth's way


There is also a theory that suggests unseen ninth planet lurking beyond Neptune may have kicked up the orbits of these detached objects. What does their collective gravity do? Bumper car-like interactions at the edges of our solar system-and not a mysterious ninth planet-may explain the dynamics of odd bodies called "detached objects", according to a new study.

In Thailand, the whale ate 80 plastic bags and died


After being found near the Malaysia border, the pilot whale was treated by veterinarians while kept afloat by buoys and protected from harmful solar radiation by umbrellas. About 18 billion pounds of plastic are dumped into oceans each year, while more than 300 marine animal species are known to have been killed by plastic pollution in Thailand's waters. Read More »

This CO2 machine could transform the way we fight climate change


At that point, one of the only ways to reverse the effects is to remove carbon dioxide from the atmosphere, where it otherwise persists for thousands of years. "We've bought the smallest scalable unit of each piece of technology we have". Commercialization of such plants would allow direct air capture to make a dent in transportation emissions by connecting low-cost renewable energy to low-carbon transportation fuels using Carbon Engineering's AIR TO FUELSTM pathway.
