A research team at the Chinese Academy of Sciences has discovered evidence that there is a mysterious barrier at the center of the galaxy that appears to block the passage of cosmic rays, yet paradoxically can also accelerate those same charged particles back nearly to the speed of light. Cosmicread more
Recent studies in theoretical physics have found that faster-than-light travel, through the manipulation of gravity—or bending the physical fabric of space-time—is not as impossible as was once thought. Although it would appear that we’re still quite a few quantum leaps away from being able to visit neighboring star systems inread more
Long-range space exploration is currently hamstrung by having to accelerate spacecraft in comparative fits and starts using rocket engines that can only fire for a few minutes at a time, followed by months, years, and even decades of the spacecraft coasting from planet to planet. However, a propulsion method thatread more
Comet Atlas may have fizzled as it came ’round the Sun, but its replacement, C/2020 F8—better known as Comet SWAN—has fared better in its approach to the center of the Solar System, and although it is likely to become just bright enough to be visible to the naked eye, skywatchers willread more
