Two rare super-Mercuries discovered in the same star system

While observing the star system HD 23472 with the ESPRESSO spectrograph (ESO), a team led by Instituto de Astrofísica e Ciências do Espaço's (IA3) researcher Susana Barros (IA & Dep. de Física e Astronomia—Faculdade ...

Roboticists discover alternative physics

Energy, mass, velocity. These three variables make up Einstein's iconic equation E=MC2. But how did Einstein know about these concepts in the first place? A precursor step to understanding physics is identifying relevant ...

How to grow plants on the moon

What do you need to make your garden grow? As well as plenty of sunshine alternating with gentle showers of rain—and busy bees and butterflies to pollinate the plants—you need good, rich soil to provide essential minerals. ...

Even stars doomed to die as supernovae can have planets

Ninety percent of all exoplanets discovered to date (there are now more than 5,000 of them) orbit around stars the same size or smaller than our sun. Giant stars seem to lack planetary companions, and this fact has serious ...

Imaging chemical kinetics at liquid-liquid interfaces

Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of ...
