Erstes Sternpärchen entdeckt, das in einer Supernovaexplosion enden wird

Astronomen haben mit Teleskopen der ESO und auf den kanarischen Inseln zwei überraschend massereiche Sterne im Zentrum des Planetarischen Nebels Henize 2-428 entdeckt, die sich gegenseitig umkreisen. Dabei werden sie sich langsam einander annähern und in etwa 700 Millionen Jahren miteinander verschmelzen. Dabei kommt soviel Materie zusammen, dass sie eine gewaltige Supernovaexplosion auslösen werden. Die neue Studie, die das Sternpaar vorstellt, erscheint am 9. Februar 2015 in der Zeitschrift Nature.

Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet’s surface and are home to the world’s greatest diversity of life. While water is essential for life on the planet, the answers to two key questions have eluded us: where did Earth’s water come from and when? (more…)

Why we embrace the ritual of Valentine’s Day: Q&A with a Yale sociologist

Whether you’re a die-hard romantic or a callous cynic, there’s no escaping the millions of couples cozying up this Feb. 14 to celebrate Valentine’s Day.

The origins of our only holiday devoted to love are somewhat murky. It is thought to have its beginnings in the Roman festival of Lupercalia, which was celebrated in mid-February. The fertility ritual included animal sacrifice, nude men, women flogged with animal hides, and a matchmaking lottery akin to a 1970s key party. (more…)

Skeletons uncovered at Ipplepen reveals major Roman cemetery

15 ancient skeletons have been discovered on an archaeological dig in Ipplepen, a major Romano-British settlement in Devon and now the best preserved Roman cemetery. University of Exeter archaeologists and a team of students and volunteers uncovered the human remains during an excavation of a Roman Road and found a roadside cemetery, the like of which has never been seen in the region.

The significance of the discovery took on further importance when one of the skeletons was found to date from around 250 to 350 years after the Roman period, an era often referred to as the ‘dark ages’. These discoveries are of both national and regional value in providing a glimpse into Romano-British life and how the settlement continued into post-Roman times. (more…)

With the help of UA researchers, archaeologists have discovered that the highest known human occupation sites also are the world’s oldest, challenging theories about the speed of human adaptation to high-altitude living

Researchers at the University of Arizona have helped determine that human occupation sites in the southern Peruvian Andes not only are the highest known in the world, but also the oldest. (more…)

Raumfahrt am Südpol – EnEx-Sonde entnimmt erstmals “saubere” Wasserproben

Ohne Wasser – kein Leben: Dieses Prinzip gilt für die Erde, aber auch für andere Himmelskörper. Wasser, das seit Millionen Jahren verborgen unter einer dicken Eisschicht liegt, kann uns etwas über die Entstehung und Entwicklung von Leben verraten. Wenn man so eine Probe bergen will, muss man allerdings darauf achten, dass keine Mikroorganismen von der Oberfläche eingeschleppt werden und die Probe sowie das Unterwasserbiotop verunreinigen. Erstmals überhaupt ist es im Rahmen des Enceladus Explorer (EnEx)-Projekts des Raumfahrtmanagements des Deutschen Zentrums für Luft- und Raumfahrt (DLR) gelungen, mit einer Einschmelzsonde – dem sogenannten IceMole (englisch für “Eis-Maulwurf”) der Fachhochschule Aachen – eine kontaminationsfreie, subglaziale Wasserprobe zu entnehmen und an die Oberfläche zu bringen. Was nun an den antarktischen “Blood Falls” auf der Erde gelungen ist, soll später einmal auch auf dem Saturnmond Enceladus möglich sein. Dafür wird das EnEx-Projekt über das Jahr 2015 hinaus fortgesetzt. (more…)

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth’s non-avian dinosaurs, according to new research from Princeton University.
