Gimball: A crash-happy flying robot (w/ Video)

Gimball bumps into and ricochets off of obstacles, rather than avoiding them. This 34 centimeter in diameter spherical flying robot buzzes around the most unpredictable, chaotic environments, without the need for fragile ...

Sun sends more 'tsunami waves' to Voyager 1

(Phys.org) —NASA's Voyager 1 spacecraft has experienced a new "tsunami wave" from the sun as it sails through interstellar space. Such waves are what led scientists to the conclusion, in the fall of 2013, that Voyager had ...

Chandra data suggest giant collision triggered 'radio phoenix'

Astronomers have found evidence for a faded electron cloud "coming back to life," much like the mythical phoenix, after two galaxy clusters collided. This "radio phoenix," so-called because the high-energy electrons radiate ...

Mount Etna eruption causes airspace closure

The Mount Etna volcano erupted on Monday, spewing ash as several minor earthquakes hit the region, and prompting a partial closure of the Sicilian airspace around the mountain.

Imaged 'jets' reveal cerium's post-shock inner strength

Recent synchrotron advances and the development of dynamic compression platforms have created the ability to investigate extreme states of matter on short timescales at X-ray beamlines using shock waves generated by impact ...

Ripples in space key to understanding cosmic rays

In a new study researchers at the Swedish Institute of Space Physics have used measurements from NASA's MMS (Magnetospheric MultiScale) satellites to reveal that there are ripples, or surface waves, moving along the surface ...

Giant cosmic tsunami wakes up comatose galaxies

Galaxies are often found in clusters, with many 'red and dead' neighbours that stopped forming stars in the distant past. Now an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral ...

How hot are atoms in the shock wave of an exploding star?

A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion. An international team of researchers, ...
