Special to CosmicTribune.com, March 20, 2022 Highlights for the week of March 18-26, 2022 Spot Arcturus very low in the east-northeast after nightfall and higher in the east later in the evening. By modern measurements Arcturus is visual magnitude –0.05, making it the fourth-brightest nighttime star. It’s bested only by Sirius, Canopus, and Alpha Centauri. […]
April 25, 2017 On April 12, as the Sun was blocked by the disk of Saturn the Cassini spacecraft camera looked toward the inner Solar System and the gas giant’s backlit rings. At the top of the mosaicked view is the A ring with its broader Encke and narrower Keeler gaps visible. At the bottom […]
September 20, 2016 It’s hard to believe that more than 4 years have passed since the Curiosity rover (a.k.a. NASA’s Mars Science Laboratory) dropped onto the broad floor of Gale crater and began its marathon exploration of Mars. Although the craft’s “primary mission” spanned only 23 months, the hope has always been that this durable, […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Sebastian Voltmer] Wandering through this stunning field of view, Mars really is in front of these colorful cosmic clouds. The mosaic contructed from telescopic images is about 5 degrees (10 full moons) across. It captures the planet’s position on Aug. 26, over 7 light-minutes from Earth and very near […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] How big is Jupiter’s moon Io? The most volcanic body in the Solar System, Io (usually pronounced “EYE-oh”) is 3,600 kilometers in diameter, about the size of planet Earth’s single large natural satellite. Gliding past Jupiter at the turn of the millennium, […]
Aug. 1, 2016 [CLICK ON IMAGE FOR HIGH RESOLUTION, NASA/JPL-Caltech/Space Science Institute] What’s behind Saturn? The first answer is the camera itself, perched on the Cassini spacecraft currently orbiting behind the planet with the most grand ring system in our Solar System. The unusual perspective places Cassini on the far side of Saturn from the […]
July 4, 2016 [CLICK ON IMAGE FOR HIGH RESOLUTION] NASA’s Juno spacecraft was to fire its main rocket engine late Monday to slow itself down from a speed of 150,000 mph (250,000 kph) and slip into orbit around Jupiter. With Juno on autopilot, the delicately choreographed move comes without any help from ground controllers. The […]
After nearly a five-year journey, Juno enjoys a perspective on Jupiter not often seen, even by spacecraft from Earth that usually swing by closer to Jupiter’s equator. Looking down toward the ruling gas giant from a distance of 10.9 million kilometers, the spacecraft’s JunoCam captured this image with Jupiter’s nightside and orbiting entourage of four […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, Johns Hopkins Univ./APL, Southwest Research Institute] The night side of Pluto spans this shadowy scene. The space-based view with the Sun behind the distant world was captured by New Horizons last July. The spacecraft was at a range of over 21,000 kilometers, about 19 minutes after its closest […]
