When I was a kid, there were nine planets and some asteroids, racing through emptiness...
It's a lot more complicated nowadays...

What's this?
Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

    Very cool seed, thank you. I am pleased that they can get this kind of data - not what Cassini was designed for, but with a bit of work they've pulled it off.

    Yea, the old solar system model as we know it is kind of outdated. Many astronomers and educators suggest updating information for young science students to reflect today's views.

    A few years back, I had attended an astronomy conference. It was hosted by the University of Toronto's astronomy club, and quite a few big names from the astronomy world showed up.

    One was our own Astronomy Professor, John Percy, and a couple of other UofT notables, including a very funny prodigy (everyone else was pretty boring) - forgot his name, he launched his very own spectroscopy instrument for the sun and the data he got back caused a little stir on how the sun was vibrating.

    The director of the Cassini program was there as well, and she gave us a good detail of why Saturn was chosen and how the mission unfolded with the problems. Its surprisingly has done well and great to know its function has expanded further than just the mission with Saturn. Wasn't really designed to pick up such emissions...

    ...how the sun was vibrating.

    That phrase doesn't even surprise nowadays! There was a time when "sunspot" was a big deal...

    There's a Cassini email newsletter that comes out about once a week -- that's how I knew about this seed. So I've been a "Cassini groupie" ever since launch. The regular flow of information makes the project rather like an "old friend".

    oh nice. Following Cassini since the beginning. Are you surprised it lasted this long?

    lol. We hear a lot from battlestar and star trek enterprise fiction groupies, not much from the REAL spacecraft groupies - which is refreshing.

    I followed the spacecraft rather distractedly at first. I had no idea how long the mission would last -- that information was surely given, but I forgot it as soon as I heard it.

    With time............
