University of Maryland geophysicist Nicholas Schmerr and Smithsonian Senior Scientist Emeritus Thomas R. Watters identified seismic activity that could pose a threat to future missions to the moon.

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably back in its early days when its inner core was fully liquid – unlike it is today. A team of geophysicists has used a simulation to show that this was highly likely.

While heliostats are used in the day, a scientist may have found a way to use them at night. 

An international team of astronomers has captured one of the most detailed images yet of a spectacular, ribbon-like jet emerging from the heart of the distant active galaxy, OJ 287. Enabled by the RadioAstron space telescope in combination with a global network of radio observatories, this breakthrough sheds new light on the extreme environments surrounding supermassive black holes and the powerful jets they launch into space.

For more than 150 years, the OJ 287 galaxy and its brightness variations five billion light years away has both puzzled and fascinated astronomers, because they suspect two supermassive black holes are merging in the core. An international research team led by Dr Efthalia Traianou of Heidelberg University recently succeeded in taking an image of the heart of the galaxy at a special level of detail.
