Beyond the habitable zone: Exoplanet atmospheres are the next clue to finding life on planets orbiting distant stars

Searching for life on other planets requires more than just measuring their distances from their stars. A future NASA telescope may help search for potentially habitable worlds.

A snapshot of relativistic motion: visualizing the Terrell-Penrose effect

The Terrell-Penrose effect states that the relativistic Lorentz contraction of fast-moving objects cannot be seen in a photograph, but it has never been verified due to the requirement of relativistic speeds of the moving object. Using femtosecond laser pulses and ultrafast photography, and virtually reducing the speed of light, the authors demonstrate the accuracy of this statement.
