A persistent influence of supernovae on biodiversity

The number of exploding stars (supernovae) has significantly influenced marine life's biodiversity during the last 500 million years. This is the essence of a new study published in Ecology and Evolution by Henrik Svensmark, ...

Ultrafast beam-steering breakthrough

In a major breakthrough in the fields of nanophotonics and ultrafast optics, a Sandia National Laboratories research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent ...

NASA's Fermi captures dynamic gamma-ray sky in new animation

Cosmic fireworks, invisible to our eyes, fill the night sky. We can get a glimpse of this elusive light show thanks to the Large Area Telescope (LAT) aboard NASA's Fermi Gamma-ray Space Telescope, which observes the sky in ...

Observations inspect X-ray radiation from Vela X-1

Using the Imaging X-ray Polarimetry Explorer (IXPE), an international team of astronomers has conducted X-ray polarimetric observations of an accreting X-ray pulsar known as Vela X-1. Results of the observational campaign, ...

Powerful yet lonely: The distant quasar left alone in its group

Looking at the night sky with the naked eye, we can only see an infinitesimal part of what the Universe contains, and the largest part cannot even be "seen". Radio wavelengths have gifted us some of the most fascinating astronomical ...

3D-snapshots of nanoparticles

X-ray diffraction has been used for more than a hundred years to understand the structure of crystals or proteins—for instance, in 1952 the well-known double helix structure of the DNA that carries genetic information was ...
