Earth, from the rings of Saturn: “In this rare image taken on July 19, 2013, the wide-angle camera on NASA’s Cassini spacecraft has captured Saturn’s rings and our planet Earth and its moon in the same frame. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself). At each footprint, images were taken in different spectral filters for a total of 323 images: some were taken for scientific purposes and some to produce a natural color mosaic. This is the only wide-angle footprint that has the Earth-moon system in it.”Down the rabbit hole….

An image, actually: Explanation: This new image features NGC 1546, a nearby galaxy in the constellation Dorado. The galaxy’s orientation gives us a good view of dust lanes from slightly above and backlit by the galaxy’s core. This dust absorbs light from the core, reddening it and making the dust appear rusty-brown. The core itself glows brightly in a yellowish light indicating an older population of stars. Brilliant-blue regions of active star formation sparkle through the dust. Several background galaxies also are visible, including an edge-on spiral just to the left of NGC 1546. I need continuing reminders that weDown the rabbit hole….

If you were anywhere north of, say, whatever latitude it is that the Pennsylvania’s northern border sits on, you were under instructions to get outside and look at the northern sky because the sun was blasting out magnetic particles that would result in potentially spectacular displays of the Aurora Borealis, or more commonly, the “Northern Lights”. The last time I saw a truly stunning display of the Aurora was back when I was in college; a bunch of us were inside doing whatever and another friend bursts in and says, “You gotta come outside and see this!” It looked like the entire skyDown the rabbit hole….

Composer Eric Whitacre, whom I have featured several times in this space before, is an always fascinating voice to return to. I had, in fact, forgotten about him until the week before the eclipse, when I looked up classical music selections inspired by space (that were not Holst’s The Planets, which is a work with which I’ve had a strained relationship over the years). Whitacre’s name came up for a piece called Deep Field, which sounded interesting. It turns out that the background of Deep Field is even more interesting. If you’re up on your Hubble Space Telescope lore, you’ll recognize the title Deep FieldDown the rabbit hole….

In Buffalo, the eclipse was simultaneously an astonishingly powerful and deeply disappointing experience. Clouds were in the forecast all along, but for the last several days, local meteorologists were constantly offering up reasons for optimism…which turned to “Sorry, we’re not clearing out until after totality, bummer, but it’ll still get dark and stuff.” I know these folks don’t control the weather, but for all the technology and scientific expertise they have, it sometimes seems that their ability to offer up any kind of reliable forecast has been whittled down to timeframes measured in hours, or even minutes. I know someDown the rabbit hole….
