One of the most massive black holes in the universe lurks at the center of the Cosmic Horseshoe

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away. The foreground galaxy's mass magnifies and distorts the image of a distant background galaxy ...

NASA's EZIE is launching to study magnetic fingerprints of Earth's aurora

High above Earth's poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the ...

Photocurrent spectroscopy uncovers hidden energy losses in water splitting

Hydrogen fuel is emerging as a clean energy source that could replace fossil fuels. One way to produce hydrogen sustainably is through photoelectrochemical (PEC) water splitting, where a photoanode such as titanium dioxide ...

Colliding plasma ejections from the sun generate huge geomagnetic storms

The sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide, they can generate powerful ...

Should astronauts be worried about Mars dust?

Every Martian year (which last 686.98 Earth days), the red planet experiences regional dust storms that coincide with summer in the southern hemisphere. Every three Martian years (five and a half Earth years), these storms ...

How carbon nanotubes give out more than they receive

Three RIKEN physicists have discovered how tiny tubes of carbon spit out light that is more energetic than the light shone on them. This finding could help to exploit the process in applications such as solar power and biological ...
