Radio galaxy NGC 3894 investigated with Fermi

Using the Large Area Telescope (LAT) onboard NASA's Fermi spacecraft, astronomers have investigated a nearby radio galaxy known as NGC 3894. Results of the study, presented in a paper published March 3, confirm the galaxy's ...

Gold in limbo between solid and melted states

If you heat a solid material enough, the thermal energy (latent heat) causes the material's molecules begin to break apart, forming a liquid. One of the most familiar examples of this phase transition from a well-ordered ...

New all-sky search reveals potential neutrino sources

For over a century, scientists have been observing very high-energy charged particles called cosmic rays arriving from outside Earth's atmosphere. The origins of these particles are very difficult to pinpoint because the ...

X-ray microscopy at BESSY II: Nanoparticles can change cells

Nanoparticles easily enter into cells. New insights about how they are distributed and what they do there are shown for the first time by high-resolution 3D microscopy images from BESSY II. For example, certain nanoparticles ...

Invisible X-rays turn blue

A new reaction system can detect X-rays at the highest sensitivity ever recorded by using organic molecules. The system, developed by researchers at Nara Institute of Science and Technology (NAIST), Ikoma, Japan; and Centre ...

Black holes eat stars in variable mood lighting

When a black hole chews up a star, it produces visible light or X-rays, but astronomers have almost never detected both types of radiation. Astronomer Peter Jonker (SRON / Radboud University) and his colleagues have now spotted ...
