Farewell, Cassini

Today’s post is a sad post, hence why I did not run with it on Friday. But on Friday, we bid adieu to the little space probe that could, Cassini. This piece is not terribly heavy on the information design, but it does include one diagram—so it counts.

The BBC put together a piece reflecting on the Cassini mission, including its little lander Huygens. If you, like your author, are interested in space-y things, this article is worth the read.

Oh the photos we've enjoyed…

The Timeline of the Voyager Mission

There are a bunch of things to look at this week, but what am I most excited about? Voyager. No, not Star Trek. (Did you know that the Vger entity from the first Star Trek film was a replica of the Voyager probes?) I am of course talking about the Voyager mission to the outer Solar System and beyond.

40 years ago today Voyager 1 lifted off from Cape Canaveral—Voyager 2 left two weeks earlier, but would reach Jupiter and Saturn after Voyager 1, hence being named 2—and it has been collecting images and data for science ever since.

On 25 August 2012, Voyager 1 emerged from the heliosheath and entered interstellar space. In other words, Voyager 1—and sometime in the next few years perhaps—is the first manmade spacecraft to ever leave the Solar System. Mankind is finally out there among the stars.

I love space things.

So JPL and NASA put together this interactive timeline of the mission, which of course continues tomorrow and for years after today until their nuclear fuel runs out.

Solar Eclipse Day

Today is Solar Eclipse Day.

Thankfully Vox has put together a great interactive piece to help you plan your day. This is for my viewing area in Philadelphia. We only max out at 75% of the sun, but that is still pretty fantastic.

I'm totally excited for this

Seven More Planets

What else did you guys think I was going to cover today? The by-elections in Copeland and Stoke? Well, yeah, we’ll likely get back to that tomorrow when we have some results. In the meantime…space!

This is an animation from the New York Times about the Trappist-1 system that has seven Earth-sized planets, a few of which could support liquid water. And since life as we know it depends upon liquid water…well, you get the idea. Go space.

So there's Doc, Dopey, Bashful…wait, wrong group of seven

New Neighbours

Among the many, many stories that broke during my month-long radio silence, I got fairly excited about the discovery of a planet orbiting Proxima Centauri. And not just any planet, but a likely rocky planet within the star’s habitable zone. Put that all together and there is the possibility that the planet could host life as we know it. How can that not be exciting? Thankfully the Guardian put together a graphic to support an article detailing the discovery.

Our Nearest Neighbour

Yesterday scientists announced the discovery of a likely rocky planet within the habitable zone of Proxima Centauri, Sol’s (the Sun’s) nearest star. The New York Times covered the discovery with a piece full of nice explanatory graphics.

Now if we can only get onto the whole matter–anti-matter warp engine thing we could go explore the place.

Quasi-satellite Asteroid Orbits

Scientists discovered Earth has a new quasi-satellite. It is an asteroid, and it does not orbit the Earth. But, because of the relationship between its orbit and Earth’s around the sun, it is involved in what NASA described as a dance with Earth. This is not Earth’s only dance partner, however, as we interact with a second asteroid as well. The screenshot of a YouTube video (from user britoca) shows how gravity choreographs the second dance.

What Comprises Planet Nine

Well, to start, we don’t really know for sure. We also don’t really know Planet Nine exists for sure. But, you plug its existence into mathematical models and it explains some of the quirks we see in the Kuiper Belt, the cloud of dust and ice at the outer reaches of the Solar System. A team of intrigued Swiss scientists then created a model exploring the range of characteristics Planet Nine might exhibit. The BBC published an article that featured an image of the interior characteristics of the plent.

Supermoon Lunar Eclipse

Last night we experienced a total lunar eclipse here in Chicago. Unfortunately, significant cloud cover meant that much of the event went unseen. That was unfortunate, because eclipses are fantastic. To explain it we have this piece from the BBC.

And for those were either unable to see it or did not know about it, here is one of the photos I took.
