For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the centuries-old remains of supernova SNR 0509-67.5 with the European Southern Observatory’s Very Large Telescope (ESO’s VLT),…

UF students are bending metal with lasers to build massive structures in orbit
In the vast vacuum of space, Earth-bound limitations no longer apply. And that’s exactly where UF engineering associate professor Victoria Miller, Ph.D., and her students are pushing the boundaries of possibilities.
In partnership with the…

Recently-Discovered Exoplanet Triggers Flares on Its Parent Star
The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface, heating and inflating the planet’s atmosphere, according an analysis of data from NASA’s…
