Physicists Have Discovered a Gigantic Magnetic Bridge Spanning Galaxies

Australian and Canadian researchers have finally observed the magnetic field generated by the Magellanic Bridge. This vast stream of neutral gas connecting two galaxies can help explain just how they were formed and evolved.

Photocatalyst makes hydrogen production 10 times more efficient

Hydrogen is an alternative source of energy that can be produced from renewable sources of sunlight and water. A group of Japanese researchers has developed a photocatalyst that increases hydrogen production tenfold.

The internet is freaking out over this spooky prediction by Carl Sagan about the future

Back in 1995, everyone’s favourite astrophysicist, Carl Sagan, published a book called The Demon-Haunted World, which warned against the dangers of pseudoscience and scientific illiteracy, and encouraged its readers to learn critical and skeptical thinking.

Astronomers uncover properties of a molecular outflow feature in a nearby starburst galaxy

An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy in Germany has revealed essential properties of a molecular outflow feature in the nearby starburst galaxy designated NGC253. The findings were presented in a paper published Jan. 18 on the arXiv pre-print repository.

All electric trains in the Netherlands are now 100% wind-powered

The Netherland's national railway company, NS, has announced that all of its electric passenger trains are now 100 percent powered by wind energy.

NS first announced their target for a wind-powered train fleet back in 2015, but they've hit their target a year earlier than planned - way ahead of their 2018 goal.

Is it Better to Walk or Run in the Rain?

Do you stay drier walking or running in the rain? Many of us run, and it seems like common sense, but this question has been debated before. MinutePhysics explains on YouTube the science behind why running is the best strategy if you don't like getting wet.

This probably isn't a mind-blowing revelation—the less time you spend in the rain, the better—but some people argue that when you're walking less of your body...

Largest age map of the Milky Way reveals how our galaxy grew up

Proud parents chart the growth of their children, but astronomers from the Sloan Digital Sky Survey (SDSS) have taken on a bigger task: charting the growth of our own Milky Way. In a result presented today at the American Astronomical Society meeting in Kissimmee, Florida, a team led by Melissa Ness of the Max Planck Institute for Astronomy in Heidelberg, Germany created the first-ever "growth chart" for our Milky Way Galaxy. Their chart, which uses the ages of more than 70,000 stars and extends halfway across our Galaxy to 50,000 light-years away, helps us read the story of how our Galaxy...

New material can harvest sunlight by day and release heat at night - ScienceAlert

As solar power becomes a bigger part of our overall energy mix, scientists are working on more efficient ways of storing the power of the Sun for use during the night-time, or on particularly cloudy days. And now a new type of material has been developed that can do just that - store solar energy when it's in abundance, and release it as heat later on as required.

Arctic Sea Ice Reaches 2015 Minimum Extent, Fourth Lowest on Record

The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder showed the annual minimum extent was 1.70 million square miles (4.41 million square kilometers) on Sept. 11. This year’s minimum is 699,000 square miles (1.81 million square kilometers) lower than the 1981-2010 average.
