These New Computer Simulations of the Sun are Hypnotic June 1, 2023
It’s almost impossible to over-emphasize the primal, raging, natural power of a star. Our Sun may appear benign in simple observations, but with the advanced scientific instruments at our disposal in modern times, we know differently. In observations outside the narrow band of light our eyes can see, the Sun appears as an enraged, infuriated […]

JWST Scans an Ultra-Hot Jupiter’s Atmosphere June 1, 2023
When astronomers discovered WASP-18b in 2009, they uncovered one of the most unusual planets ever found. It’s ten times as massive as Jupiter is, it’s tidally locked to its Sun-like star, and it completes an orbit in less than one Earth day, about 23 hours. Now astronomers have pointed the JWST and its powerful NIRSS […]

If You’re Going to Visit Venus, Why Not Include an Asteroid Flyby Too? June 1, 2023
A recent study submitted to Acta Astronautica examines the prospect of designing a Venus mission flight plan that would involve visiting a nearby asteroid after performing a gravity assist maneuver at Venus but prior to final contact with the planet. The study was conducted by Vladislav Zubko, who is a researcher and PhD Candidate at […]
