(You can unsubscribe anytime). Since Jupiter has very little axial tilt relative to its orbit, and since the moons of Jupiter orbit around its equator, they often cast their shadow on Jupiter. When the tides generated by other objects in Jupiter's moon system match each moon's own resonant frequency, the moon begins to experience more heating than that due to tides raised by Jupiter alone, and in the most extreme cases, this could result in the melting of ice or rock internally. On … Jupiter is in conjunction with the Sun on January 28, 2021, and re-emerges in the dawn sky early in February. According to the researchers' model, Jupiter's influence alone can't create tides with the right frequency to resonate with the moons because the moons' oceans are thought to be too thick.

Hay also is hoping that future studies will be able to infer the true depth of the oceans within these moons. As a result, some of the icy moons contain interiors warm enough to host oceans of liquid water, and in the case of the rocky moon Io, tidal heating melts rock into magma. "Maintaining subsurface oceans against freezing over geological times requires a fine balance between internal heating and heat loss, and yet we have several pieces of evidence that Europa, Ganymede, Callisto and other moons should be ocean worlds," said co-author Antony Trinh, a postdoctoral research fellow in the Lunar and Planetary Lab. Jupiter is an interesting object to look at. July 25, 2005, By: Bob King As 2020 begins, Jupiter is visible in morning twilight and rises progressively earlier as each month goes by.
