Hubble snaps a crowded cluster

This sparkling burst of stars is Messier 75. It is a globular cluster: a spherical collection of stars bound together by gravity. Clusters like this orbit around galaxies and typically reside in their outer and less-crowded areas, gathering to form dense communities in the galactic suburbs. Read More

Flexible circuits for 3D printing

A research cooperation has developed a process suitable for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The technique can enable new applications such as printable light-emitting diodes, solar cells or tools with integrated circuits, as the scientists report in the journal Scientific Reports.…
