Nice! this is interesting. I actually did not know that there are names for the moons of Saturn. Well, thanks for this thread, now I know hahah! It is also interesting that there is almost a name for everything. Seems like these astronomers will never run out of names. Ohhhh if it is the most habitable spot beyond Earth. There is a possibility that we will live on a moon and not a planet? hahah does gravity exist or not hahah. Thanks for this again. New learning every day! I do hope to read more like this and learn more about the wonders galaxy.

Really? Is Juno a 10 year old doing a Tic Toc video?

This animation depicts the orbit of NASA's Juno spacecraft at Jupiter in 2016 and 2017. Over about 15 months, Juno makes 33 orbits around the giant planet's poles, coming to within 3100 miles of Jupiter's cloud tops every 11 days. The movie shows how repeated passes allow Juno to map the entire planet over the course of the mission. Jupiter rotates every 10 hours, and Juno's 11-day-long orbit is timed so that during each close approach, the spacecraft flies over a different swath of the planet. By the end of the mission, Juno's accumulated coverage wraps Jupiter in a web with lines spaced 12 degrees apart around the planet. Green and blue orbit lines indicate different science activities that are the focus of those orbits (gravity science or microwave radiometry, respectively). The yellow-colored orbit is a final pass held in reserve for additional science activities, and the red orbit represents the de-orbit into Jupiter at the conclusion of the science mission.

A Journey to the End of the Universe​

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

Written and presented by Professor David Kipping.

What would happen if we built a real Dyson Sphere?
