Alexandra de Castro
I tell science stories in English and Spanish. The same passion for science that once drove me to obtain a Ph.D. in physics, and work as a research scientist for fifteen years, inspired me to steer my career towards the popularization of science. Since 2014, I have been writing, editing, and managing outreach projects for several organizations. In 2021, I joined United Academics Magazine as Editor-in-chief. My favorite topics are theoretical physics, particle physics, climate change, astronomy, and space exploration.

Bug-sized Mountains That Might Power Ripples in Space-time
Fabian Gittins and Nils Andersson from the University of Southampton in the UK simulated the forces that may cause imperfections in neutron stars. They are trying to find out how these hypothetical mountains would have emerged and how large they would be. The scientists modeled the highest peak a neutron star crust can support, i.e., before the crust fractures.
Scientists reveal Mars’ inner structure
When the Greeks observed the errant lights in the sky—which they named planets—they probably never envisioned that, one day, we could actually reach the...
Robotic space arm from ESA that can see, feel, and think
During spacewalks, the last thing you need is legs: you only need a very skilled arm along with a brain, and eyes. For this...
