Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.
Ganymede is one of the largest satellites in our solar system, it orbits the gas giant Jupiter and also has a magnetosphere. In the Expanse a gigantic agricultural project calls Ganymede home, the favorable conditions on the planet make it one of the bread baskets of the belt. The question is can we also one day colonize this Jovian moon? FACEBOOK: INSTAGRAM: What we're reading and watching: FOLLOW OUR HOSTS What we're reading and watching: Allen Xie: Ben Hedges:
If you have two pennies to throw away on a bet about alien life, bet them on Ganymede. And not on Mars! And now, with your permission, I would like to explain why. Ganymede: Odds of Alien Life? - - Subscribe for more videos ► Patreon ► Business Enquiries ► - - And as I was telling you, I confirm that based on these ratings, my absolute favorite is Ganymede, the largest moon in the solar system, Ganymede, you know, is the third of Jupiter’s four large moons, with volcanic Io and ice-rich Europa located interior to it, and the heavily cratered Callisto orbiting beyond it. Ganymede is tidally locked to Jupiter, meaning that its same “face” always points toward the gas giant planet, but since it’s relatively close to Jupiter at an orbital distance of 1.07 million kilometers, it still manages to complete a full revolution around Jupiter — and hence, a full 360° rotation about its axis - every 7 days. In fact, it only has a very thin atmosphere, and a surface pressure provided by a layer of (mostly oxygen) gas. It would take approximately 100 billion Ganymede atmospheres all piled atop one another to achieve the pressures we find here on Earth. And you know... with an atmosphere that provides so little pressure, it’s impossible to have liquid water on the surface. No liquid water, no life, case closed, right? So, without an atmosphere, why would we consider Ganymede at all as an interesting world to examine for life. - - "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license. in its different versions such as 1.0, 2.0, 3,0, and 4.0 – permitting commercial sharing with attribution given in each picture accordingly in the video."

One of the big questions related to this discovery concerns Ganymede’s interior structure, and its evolution.
Three frame grabs from the computer simulation. The numbers in each frame are the seconds after impact. In the third frame, there is a sharp distribution of material at 0 km which the researchers say is a numerical artifact of the simulation, and not real. Image Credit: Hirata et al, 2020.
Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System. But talk to planetary scientists, and they’re just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice. The perfect environment for life to thrive. We’ve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And they’re not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer. Our Book is out!

Russia's Proposed Mission to Ganymede in russian! Ганимед: на пороге открытий
Published on Jul 29, 2016 В НПО имени Лавочкина, где создавались все отечественные межпланетные станции, а сейчас строятся аппараты
лунной программы и орбитальные обсерватории серии «Спектр», прорабатывается проект «Лаплас». Это два аппарата,
которые в ближайшее десятилетие планируют отправить к Юпитеру. Цель исследований - спутник Юпитера – Ганимед.
Еще один объект изучения – Меркурий. Планета входит в т.н. «земную группу планет», но знания землян о нем – самые общие.
Этот пробел должна восполнить миссия «БепиКоломбо». В проекте принимают участие ЕКА, Роскосмос и JAXA.
На аппарате, который отправится к самой маленькой планете Солнечной системы через два года, будет установлен

Halloween is just around the corner. And in what appears to be an act of cosmic convergence, Hubble captured a spooky image of Jupiter
staring back at us with a cyclops eye!
While this is merely a convenient illusion caused by the passage of Ganymede in front of Jupiter ?
something it does on a regular basis ? the timing and appearance are perfect.

Many people think that the answer to ‘what is the largest moon in the Solar System’ is our Moon.
It is not. Our Moon is the fifth largest natural satellite. Ganymede, a moon of Jupiter, is the largest in this solar system.

The last time we saw Jupiter’s largest moon Ganymede up close was over two decades ago. Now NASA has released new closeups of the moon, taken on June 7, 2021, by the Juno orbiter. The stunning images reveal Ganymede’s icy surface in striking detail. S ►ubscribe for more videos Patreon ► Business Enquiries ► Lorenzovareseaziendale@gmail.com A mysterious world, that Juno is helping to bring back to the center of scientific attention after a period of relative silence. But before talking about the Juno flyby. The scenario that is slowly composing has something incredible. Before the Voyager and Galileo missions, there were even those who thought that the Galilean satellites were worlds without particular characteristics of relief, probably united by a unique genesis and undifferentiated by surface characteristics and internal structure. For some time now, Ganymede has been added to the list of possible worlds that could hide an ocean in their , thanks to the recent discovery of a magnetic field that surrounds it. But let's not get ahead of ourselves and first introduce Ganymede in terms of history and numbers.

Well, hello there old friend! This week the Juno mission to the Jupiter system made the first close flyby of Jupiter’s giant moon Ganymede, and as you might guess, the images are spectacular. This is the first time we’ve seen a close-up view of the Solar System’s largest moon since the Galileo mission 20 years ago. Voyager gave us the first views of Ganymede 40 years ago. Now, planetary scientists will be able observe any changes in Ganymede’s surface over time.
The images were taken on June 7, 2021, as Juno swung past Ganymede. One image is from the Jupiter orbiter’s JunoCam imager and the other from its navigation camera, called the Stellar Reference Unit. Both images show the surface in remarkable detail, including craters, clearly distinct dark and bright terrain, and long structural features possibly linked to tectonic faults.

Ganymede has been getting alot of attention lately. It was the co-star of a video from Juno recently, and now scientists found something to make it an even more intriguing place visit – water vapor. Image of Ganymede from Hubble in 1996 Credit – ESA / Hubble, NASA, J. Spencer

NASA Goddard 836K subscribers Astronomers have used new and archival datasets from NASA’s Hubble Space Telescope to uncover evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede. The vapor is present due to the thermal excitation of water molecules from the moon’s icy surface. Previous research has offered circumstantial evidence for the moon containing more water than all of Earth's oceans. However, temperatures there are so cold that water on the surface freezes and the ocean lies roughly 100 miles below the crust.
