There's an element of déjà vu in the most recent political news on climate change: UN-led talks, like the recent Lima summit, that end with disgruntled environmentalists and plans for yet another summit. At this point, our best hope is to mitigate the effects of global warming (which is occurring faster than previously thought) and, if possible, keep temperature rises to a maximum of 2° C (3.6° F). While the future of the planet looks uncertain with unpredictable climate patterns, U.S researchers looking to the past to gain a better understanding of modern climate change have found the rate of modern, human-caused global warming resembles that which occurred almost 56 million years ago much more closely than previously thought.  Read More

A view of Mesoloft-transported cremains being released 20 miles above the Earth's surface

Some people choose to honor the memory of a lost loved one by doing something creative with their ashes. What's more creative than taking their remains to the very top of the Earth's atmosphere and releasing them? That's what Mesoloft is offering to those who want to say goodbye in a way that no one will ever forget.  Read More

Artist's concept of MAVEN in Mars orbit (Image: NASA/GSFC)

After completing its 10 month-long voyage, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is taking its first look at the Martian atmosphere. Part of the unmanned orbiter’s commissioning phase, it limbered up its sensors by observing the effect of a massive solar event and returned its first images of the fountain-like coronas that are slowly peeling away the Red Planet's atmosphere.  Read More

The assets that will be used to observe Siding Spring as it skims past Mars (Image: NASA)

NASA is busy readying its considerable arsenal of scientific instruments, spacecraft and rovers for a close encounter with comet C/2013 A1 on Sunday, Oct 19. The comet's closest approach with a planetary body will be with Mars, at which point it will miss the Red Planet by only 87,000 miles (140,013 km), less than half the distance between Earth and our moon, traveling at speeds of up to 126,000 mph (202,777 km/h).  Read More

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has successfully completed a maneuver designed to place the robotic explorer in Mars orbit. The achievement is the crowning moment in a 10-month journey through deep space, representing the culmination of millions of dollars and over a decade of planning and hard work by NASA mission operators.  Read More

A new study from Lund University asserts that regional climate is influenced by the sun (I...

In a new study that may greatly add to our understanding of the drivers behind climate change, researchers from Lund University in Sweden claim to have accurately reconstructed solar activity levels during the last ice age. By analyzing trace elements in ice core samples in Greenland and cave mineral formations in China, the scientists assert that regional climate is more influenced by the sun than previously thought.  Read More

Scientists suggest looking for industrial pollution as a new way of searching for extrater...

According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018.  Read More

Facing the alternative of a fiery death, the ESA’s Venus Express orbiter has completed a daring maneuver that extended the life of the unmanned explorer by several months. Under command from Earth, the spacecraft spent a month skimming the outer edge of the Venusian atmosphere to alter its velocity and send it into a new orbit that will keep it operating until perhaps the end of the year.  Read More

NASA scientists have installed the largest heat shield ever created for the intention of atmospheric re-entry, onto the crew module of its next generation spacecraft, Orion. The shield, made of the same base material as that which protected Apollo-era astronauts from re-entry conditions over four decades ago, is set to be tested to the extreme later this year as Orion's maiden flight blasts off.  Read More

Data collected from observations recorded by NASA's Cassini mission has been used to propose ways to better understand the atmospheres of exoplanets. By studying the light of sunsets on Saturn’s satellite, Titan, scientists have shown how spectra are subtly altered when passing through a hazy atmosphere, thereby giving a greater insight into interpreting the spectral readings of the atmosphere of these distant worlds.  Read More
