Lund University, Sweden researchers has developed a camera that can film at a rate equivalent to 5 trillion images per second, or events as short as 0.2 trillionths of a second. This is faster than has previously been possible. The new camera will therefore be able to capture incredibly rapid processes in chemistry, physics, biology and biomedicine, that so far have not been caught on film. The researchers have successfully filmed how photons travels a distance corresponding to the thickness of a paper. In reality, it only takes a picosecond, but on film the process has been slowed down by a trillion times.

Currently, high-speed cameras capture images one by...

The bright object seen in this Hubble image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy. Credit: NASA/ Hubble ESA

Galaxy NGC 7250, despite being remarkable in its own right – it has bright bursts of star formation and recorded supernova explosions – it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it. The bright object seen in this Hubble image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy.

Only this way can a normal star outshine an entire galaxy, consisting of billions of stars...

2. Simulation of Chariklo’s ring system. Using a particle density equal to half of Chariklo’s density, the overall structure can be maintained. In the close-up view (right) complicated, elongated structures are visible. These structures are called self-gravity wakes. The numbers along the axes indicate distances in km.

A team in Japan modeled the 2 rings around Chariklo, the smallest body in the Solar System known to have rings. This is the first time an entire ring system has been simulated using realistic sizes for the ring particles while also taking into account collisions and gravitational interactions between the particles. The team’s simulation revealed information about the size and density of the particles in the rings. By considering both the detailed structure and the global picture for the first time, the team found that Chariklo’s inner ring should be unstable without help...
