Amy Lien is an Assistant Professor of Physics at the University of Tampa whose research interests lie in understanding how the universe begins and evolves through the most energetic astrophysical explosions: gamma-ray bursts (GRBs), supernovas, merging neutron stars and black holes. When faraway...

Seasonal, spider-like features have been spotted sprouting through cracks in Mars’ surface. The European Space Agency’s Mars Express orbiter captured new images of small, dark features that resemble spiders scuttling across the Martian region known as Inca City near the Red...
