Siberian sinkhole believed to be effect of global warming

Siberian sinkhole believed to be effect of global warming

A strange sinkhole at “the end of the world” has scientists baffled. Nobody knows quite why it’s there, or what could have prompted its formation. Early theories suggest it’s an effect of global warming, though no specific cause has been identified. Other speculate space debris could be to blame.

Gliese 832c possibly habitable but has extreme seasons

Gliese 832c possibly habitable but has extreme seasons

Don't get your hopes up yet for galactic colonization, but a new planet has just been added to the Habitable Exoplanets Catalog. Gliese 832 c of the Gliese 832 star system is theorized to have temperatures close to Earth's, making it possibly habitable except for one glaring flaw: it has large seasonal shifts.

Apple issues Earth Day burn to Samsung

Apple issues Earth Day burn to Samsung

A number of publications being distributed across the UK this week are carrying an Apple-made advertisement coinciding with Earth Day. As Apple’s ongoing court case with Samsung rolls on in the background, these ads run right out in public, suggesting one very pointed issue. "There are some ideas we want every company to copy," it says, suggesting that their eco-friendly initiatives are not under copyright like their patents.

B612 says Earth avoids massive asteroids with “blind luck”

B612 says Earth avoids massive asteroids with “blind luck”

With Earth Day round the bend, you’d expect to hear some positive news regarding our planet and the celestial bodies that surround it; instead we have some not-so-good-news. According to former NASA astronauts, we're depending on "blind luck" when it comes to the asteroids avoiding our planet. Apparently we get hit three to ten times more by large-scale asteroids than what is being officially declared by the authorities, this information being brought forward by this trio of space-fairing fellows this week.

NASA Van Allen probes confirm Earth as giant particle accelerator

NASA Van Allen probes confirm Earth as giant particle accelerator

The NASA Van Allen twin probes launched last year have revealed that the Earth is a giant particle accelerator. Recently it was reported that particles in the magnetosphere sometimes accelerate across distances of a few hundred meters. But the newer discovery shows the acceleration can occur across hundreds of thousands of kilometers. The data will be helpful to to scientists helping satellite operators and the International Space Station to predict and prepare for the destructive tendencies of the seemingly random fluctuations that can occur in the magnetosphere.

Stanford scientists use 3D imaging to reevaluate Earth core formation

Stanford scientists use 3D imaging to reevaluate Earth core formation

Scientists at Stanford University have demonstrated how the formation of Earth's core is even more complicated than previously understood. Using new 3D imaging techniques, the scientists used a pair of diamonds to squeeze molten metal through rocks under pressure, showing that iron can be squeezed out of rocky silicates deep beneath the surface of the planet.

NASA shows us what Antarctica would look like without ice

NASA shows us what Antarctica would look like without ice

Due to its location, the frigid continent of Antarctica is covered with nothing but ice, making it seem like the continent is nothing but boring flat land. However, thanks to a computer-generated simulation, we get to see that Antarctica is actually bumpy and pretty unique -- it's just that we don't get to see it with all that ice covering it up.

Chris Hadfield and crew safely return to Earth from International Space Station

Chris Hadfield and crew safely return to Earth from International Space Station

We get all sorts of welcomes in life, but few of them are as grand as the one you'd no doubt receive returning to Earth after having hovered above it for 144 days. Such was the case for Commander Chris Hadfield and the rest of his crew that was aboard the International Space Station, all of whom have just safely landed on our home planet in Dzhezkazgan, Kazakhstan.

Earth’s carbon dioxide levels reach near-record high

Earth’s carbon dioxide levels reach near-record high

According to scientists and researchers at the National Oceanic and Atmospheric Administration, carbon dioxide levels on Earth have reached a level that hasn't been seen in at least three million years. Scientists believe that large changes in the climate and sea levels are to blame for the rising amount of carbon dioxide.

Study suggests water on the Moon came from Earth

Study suggests water on the Moon came from Earth

Scientists and researchers have discovered that droplets of water found in lunar rocks brought back from the Moon are identical on a chemical level from that of samples of ancient Earth. The rocks used in the study came from samples brought back by Apollo 15 in 1971 and Apollo 17 in 1972, the latter being NASA's last mission to the moon.

Google Timelapse shows a changing Earth in animated form

Google Timelapse shows a changing Earth in animated form

Google has launched a new project called Timelapse that allows users to see the history of the Earth all the way back to 1984 and view how our planet has changed over the past 28 years. You can view any part of the world, just like in Google Earth, except that Timelapse automatically creates an animated timelapse GIF based on what you're looking at.

New photo from ISS shows moon rising over a darkened Earth

International Space Station Commander Chris Hadfield has been busy taking photos of the Earth from the ISS for a few months now, mostly showing us what cities look like from 250 miles up, but a particular photo that he posted just recently is a bit different, and it shows a beautiful horizon with the moon rising over a darkened Earth.
