The exploration of Jupiter — the biggest and most extreme planet in the Solar System — may change humanity's understanding of the Solar System.Recent discoveries by the National Aeronautics and Space Administration (NASA) Juno mission uncover what lies beneath Jupiter's violent storms and reveal that Jupiter is more akin to a star than a planet.
The very first visible-light images of Venus' surface from space have been captured by NASA's Parker Solar Probe, and it could help researchers piece together the mysteries of the distant planet.
Venus is the second planet from the Sun, making a full orbit in about 224 days. Venus orbits the Sun at an average distance of about 0.72 AU (108 million km; 67 million mi), and completes an orbit every 224.7 days. It completes 13 orbits in 7.998 years, so its position in our sky almost repeats every eight years.
The European Space Agency has officially adopted two new space missions to study Venus from its atmosphere to inner core and to search for gravitational waves.
EnVision will look at the geology and atmosphere of our neighbouring planet to help determine why Earth became the only known planet to sustain life.
In the Dresden Codex, the Maya included an almanac showing Venus's full cycle, in five sets of 584 days each (approximately eight years), after which the patterns repeated (since Venus has a synodic period of 583.92 days). [12] The Maya were aware of this synodic period, and could compute it to within a hundredth part of a day. [11]
The full cycle from new to full to new again takes 584 days (the time it takes Venus to overtake the Earth in its orbit). Venus (like the Moon) has 4 primary phases of 146 days each. The planet also changes in apparent size from 9.9 arc seconds at full (superior conjunction) up to a maximum of 68 arc seconds at new (inferior conjunction). [1]
