Earth & Space News
Today's earth & space headlines from the sources selected by our team:

A perfect sun-storm
A geomagnetic storm on January 17, 2013, provided unique observations that finally resolved a long-standing scientific problem. For decades, scientists had asked how particles hitting Earth's magnetosphere were lost. A likely mechanism involved certain electromagnetic waves scattering particles into the Earth's atmosphere. More recently, another mechanism was proposed that caused particles to be lost in interplanetary space. Scientists recently found that both mechanisms play a role affecting particles at different speeds.

Cosmic dust demystified
Besides providing substantive information about the atmospheres of other planets, cosmic dust particles can impact radio communications, climate and even serve as fertilizer for phytoplankton in the oceans. A team of researchers has developed a new experimental Meteoric Ablation Simulator (MASI) that can help answer questions about cosmic dust and how it impacts Earth and everything on it.

Hubble spots possible water plumes erupting on Jupiter's moon Europa
Astronomers have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

Europa Orbiter Could Sample Jovian Moon's Watery Plumes
NASA's Europa orbiter mission, set to launch toward Jupiter's moon in the 2020s, would be able to collect samples of the icy plumes of water that might erupt from Europa's surface., Wed, 28 Sep 2016 16:01:03 GMT

What's Going on Under the Ice of Europa?
It's only in the habitable zone — the "Goldilocks" region around a star where water can exist in liquidy peace — that life is possible. Or so scientists thought., Wed, 28 Sep 2016 16:01:03 GMT

The Hunt for Dark Matter Minihalos Offers Glimpse into Early Universe Inflation
Two of cosmology's greatest mysteries — dark matter, and the expansion of the early universe — are tied together in a new research paper, which searches for small, dense knots of one to understand the other., Wed, 28 Sep 2016 16:01:03 GMT

Rosetta may be crashing, but can still save lives on Earth
The Rosetta Mission will end with a controlled descent to the surface of Comet 67P on Friday 30 September 2016; however, its legacy will live on in applications on Earth, developed by academics at The Open University, including detecting cancer and sniffing bed bugs.

Research resolves a debate over 'killer electrons' in space
New findings by a UCLA-led international team of researchers answer a fundamental question about our space environment and will help scientists develop methods to protect valuable telecommunication and navigation satellites. The research is published today in the journal Nature Communications.

Making space rocket fuel from water could drive a power revolution on Earth
Researchers led by NASA's former chief technologist are hoping to launch a satellite carrying water as the source of its fuel. The team from Cornell University, guided by Mason Peck, want their device to become the first shoebox-sized "CubeSat" to orbit the moon, while demonstrating the potential of water as a source of spacecraft fuel. It's a safe, stable substance that's relatively common even in space, but could also find greater use here on Earth as we search for alternatives to fossil fuels.

Confirming the structure and shape of polar cap patches
Large-scale patches of enhanced electron density (plasma) are often found in the polar ionosphere - about 80 to 1000 kilometers above the Earth's surface. These 'polar cap patches' can last for hours, cover huge areas and travel quickly, and their presence can disrupt satellite communication links.
