It’s been nine months since NASA’s New Horizons spacecraft flew past Pluto. Time sure does fly. And even though the spacecraft is moving further from Pluto and Earth, it’s still sending back the massive amounts of data it gathered during closest approach. As this data is received, the huge team of scientists that are part of the mission use it to characterize Pluto so humanity can begin to understand just how strange the distant dwarf Planet is. Five new papers characterize some of the latest science done on the enigmatic world. Here’s a quick summary of each: The first paper from...
Now that New Horizons has passed by Pluto and it’s moons, it’s time we updated out images of the entire system. Taking images from New Horizons, today’s APOD shows the relative sizes of the moons with the best photos we have of them to date. Looking at the image, it makes sense that Nix and Hydra weren’t discovered until 2005, and that Kerberos and Styx were not found until 2012. The moons are so tiny and distant, and are dwarfed by the larger Charon and central Pluto. As far as we know, this is it for Pluto’s moons, since we haven’t...
The high resolution data keeps on coming in from New Horizons, now far beyond the dwarf planet Pluto. Using some of the images as the craft flew by, mission scientists were able to create a fantastic video that gives you some perspective as if you were flying along yourself. We can see Charon and other moons during the early and later stages of the fly-by, with the orbits overlaid, giving perspective on how the Plutonian system’s mechanics work. As the craft approaches Pluto, time slows down to appreciate the closest approach and see the stunning detail revealed in the...
As we are approaching the New Horizons bypass of Pluto just over a month from now, there is a lot of focus on the Plutonian system, from its strange Moons to its enigmatic surface. As we wait for the first ever high resolution images of the surface of Pluto, we can look to Hubble data to give us our fix. The best image of Pluto taken up to today, by Hubble, is blurry and at best can lead us to speculation about what we are seeing. But Hubble, as always, produces valuable science, and has given new insights into the...
