Electric Blue Clouds Appear over Antarctica

New data from NASA’s AIM spacecraft show a vast bank of noctilucent clouds blanketing Antarctica. Data from NASA’s AIM spacecraft show that noctilucent clouds are like a great “geophysical light bulb.” They turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days.

Scientists Reveal Earths Remaining Habitable Lifetime

By using habitable zone and stellar evolution models, astrobiologists from the University of East Anglia have estimated that habitable conditions on Earth will be possible for at least another 1.75 billion years. Findings published today in the journal Astrobiology reveal the habitable lifetime of planet Earth – based on our distance from the sun and […]

Scientists Solved Riddle about Which Direction the Center of the Earth Spins

In a newly published study, researchers from the University of Leeds detail how they solved a 300-year-old riddle about which direction the center of the Earth spins, linking the observed westward drift of the magnetic field and superrotation of the inner core. Scientists at the University of Leeds have solved a 300-year-old riddle about which […]

Could Life on Earth Have Originated from Somewhere Else

New research presented at the European Planetary Science Congress at UCL examines whether life forms would be able to survive an impact with the surface of the Earth, opening the door to the possibility that life did not originate on Earth but came from elsewhere in the universe. It sounds like science fiction, but the […]

Mega Canyon under Greenland Ice Sheet Discovered

Scientists have discovered a previously unknown canyon hidden beneath two kilometers of ice in Greenland. The canyon is at least 750km long and in places as much as 800m deep. Hidden for all of human history, a 460 mile long canyon has been discovered below Greenland’s ice sheet. Using radar data from NASA’s Operation IceBridge, […]

Material Deep in the Mantle May Help Explain Earths Origin

Scientists at MIT have discovered a “hidden flux” of material deep in the Earth’s mantle that would make the planet’s overall composition more similar to that of meteorites, supporting the theory that Earth arose from the collision of asteroids. It’s widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a […]

New Research Suggests Life on Earth Came from Comets

A newly published study suggests that life on earth may have started as a result of icy comets that crashed into Earth billions of years ago. Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this […]

Climate Change Shifts Northern Growing Seasons

In a newly published study, scientists examined the relationship between changes in surface temperature and vegetation growth, finding that temperature and vegetation growth at northern latitudes now resemble those found at 4 degrees to 6 degrees of latitude farther south as recently as 1982. Vegetation growth at Earth’s northern latitudes increasingly resembles lusher latitudes to […]

New Way to Probe the Deep Earth Interior

In a newly published study, university researchers propose a new way to probe Earth’s deep interior that relies on a fifth force of nature called a long-range spin-spin interaction. Researchers from Amherst College and The University of Texas at Austin have described a new technique that might one day reveal in higher detail than ever […]

Antarctic ozone hole measured this year was the second smallest in the last 20 years

Data from NASA and NOAA satellites show that the average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years. Scientists believe natural fluctuations in weather patterns played a role in this change. This video shows the status of the ozone hole between July 1, 2012 to […]

The floor of the ocean is home to 2.9×1029 single-celled organisms but this large number, 10 million trillion microbes for every human on planet Earth, is only 8% of the previous estimate of  35.5×1029. Jens Kallmeyer, a geomicrobiologist and his colleagues at the University of Potsdam in Germany have created the most accurate model of […]
