NASA releases hypnotizing new image of Earth

While much of the buzz from NASA recently has been about the New Horizons' trip to Pluto, the agency hasn't totally forgotten about the blue orb we inhabit. Captured from a camera on the Deep Space Climate Observatory, NASA has just released the satellite's first view of the sunlit side of Earth from 1 million miles away, and it sure is stunning. The image shows North and Central America, with the Caribbean islands located in the turquoise areas in the center.

We’re three minutes from Doomsday

We’re three minutes from Doomsday

Climate change and the unrelenting development and stockpiling of nuclear weapons have seen the Doomsday Clock pushed another minute closer to global disaster, with scientists warning that we're three metaphorical minutes from destruction. The clock, a symbolic representation of how close humanity is to teetering on the edge of effective annihilation by its own hand, is now just three minutes from midnight, with the team in charge of the hands - the Bulletin of Atomic Scientists, counting seventeen Nobel Prize laureates among its members - ominously suggesting that "the probability of global catastrophe is very high."

Sub shows Antarctic ice not as thin as we thought

Sub shows Antarctic ice not as thin as we thought

When we discuss the overall health of our planet, we typically have to entertain the idea that ice is melting at a rate quicker than we’re comfortable with. The way we currently measure ice is via satellite flyovers and boring through ice caps, which doesn’t give as accurate a picture as we’d like. A new submarine, dubbed SeaBED, is taking much of the work below the surface. The unmanned sub sends a sonar blast from the bottom, and what we’re learning is that ice caps may not be as thin as we’d imagined.

Study: lightning strikes will increase with global warming

Study: lightning strikes will increase with global warming

In a picture of the dystopian future many paint for us, the world is scorched, and full of powerful storms. A new report suggests that might not be too far from the truth, should climate change continue unfettered. In a study published today in the Journal of Science, we find that the new thinking around climate change will bring increased lightning storms. According to the study, every two degrees fahrenheit we see in global warming will result in 12% more lightning in the US.

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.
