First discovery of an NEO by ATLAS telescope

The term “killer asteroid” might bring to mind the kind of massive space rock that wiped out the dinosaurs millions of years ago. But such a large object — around 5 to 15 kilometers (3 to 8 miles) across — might hit Earth only once every few hundred million years. Smaller space objects hit more often. And even these minis can be dangerous. An asteroid just 45 meters (50 yards) wide could destroy a city. But the first in a new two-telescope system in Hawaii has just begun scanningthe skies for such “city-killers.” And what it finds might give people a life-saving warning of their approach.

Solving the Mystery of How Sunspots are Formed

Sunspots Sure, the sun’s light and heat make life possible on Earth, and its gravity holds our entire solar system together. But our nearest star remains surprisingly enigmatic.

Scientists still don’t know, for example, why its magnetic activity fluctuates in an 11-year solar cycle. Or how powerful solar flares can knock out satellites, disrupt GPS systems, and fry electrical grids here on Earth.

What they do know is that sunspots—those randomly-spaced dark blotches on the sun’s surface—are a critical part of that puzzle. In September, an international team of scientists was able to show, for the first time, how magnetic activity in the sun’s interior leads a sunspot to form. And it revealed how that energy is later released in plasma jets and explosions, phenomena similar to powerful solar flares.

What will a Native Hawaiian economy look like?

Hawaiian-Economy-960x360

It’s not clear how Native Hawaiian self-governance will affect Hawaii’s economy, but there is no shortage of ideas. Different Hawaiian leaders talk about changing taxes, control of land, lease rents, business incentives, ownership restrictions, import rules and much more.

Is your hospital prepared for a disaster?

“Are you breathing?”

Emergency-Room Doctor David Williams leans over a “patient” covered in realistic-looking ash and blood. Surrounding him in the pop-up hospital tent lie a dozen more volunteer victims, ready for triage after a plane has crashed at Kahului Airport.

Don’t worry yet, it’s a simulation, part of a training program by Maui Memorial Medical Center and other local emergency-service providers to prepare their staffs for a mass casualty disaster.
