Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»

By peering into the cosmic dance of stars, a team led by researchers from the Leibniz Institute for Astrophysics Potsdam (AIP) has unraveled the complex structure of our Milky Way galaxy. Assuming that each observed star represents a larger populatio.....»»
Arctic Siberia summers were up to 10°C warmer than today during the Last Interglacial, study finds
Interglacials are, as the name suggests, warm periods between planetary glaciations when the expanse of ice on Earth shrinks. Currently, we are in an 11,000 year-long interglacial period known as the Holocene. Prior to this, the Last Interglacial occ.....»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Sentinel-1 data reveals Arctic glacier retreat
As Arctic temperatures rise, marine-terminating glaciers—especially in places like Svalbard—are undergoing rapid retreat and intensified calving. The Space for Shore project utilizes radar data from the Copernicus Sentinel-1 mission to provide pr.....»»
