There’s some craking images from ESA this week, I’ve put some of them on here. Like the cluster of galaxies that are creating a gravity lens, the radio telescope searching for Cassini between close passes with Saturn and a view of Amsterdam from ISS.
Cassini is now on it’s way towards it’s grand and ultimately destructive finale! Using Saturn’s largest Moon titan to fling it into a polar orbit between Saturn’s ring and it’s outer atmosphere it will complete 22 weekly obits of Saturn before plunging into Saturn’s atmosphere on September 15th
In case you didn’t know, today is Earth day. A day where we focus on this self supporting spacecraft whizzing through the cosmos that we call home. We need to help this world keep us alive and looking amazing…
As usual I like to see things a bit differently. What better way than from Saturn…
That tiny spec is Earth… Us. All of us, everything we are, eat, drink everything we want for our phones, computers and everthing we use as fuel for our homes and cars.
There we are again. Between the rings. Small aren’t we? But we think big and we can sort out what we do about how we live our lives.
This isn’t a call to arms or a wake up call… Its a dream really.
This is a composite image of Uranus by Voyager 2 and two different observations made by Hubble — one for the ring and one for the auroras.
Ever since Voyager 2 beamed home spectacular images of the planets in the 1980s, planet-lovers have been hooked on auroras on other planets. Auroras are caused by streams of charged particles like electrons that come from various origins such as solar winds, the planetary ionosphere, and moon volcanism. They become caught in powerful magnetic fields and are channeled into the upper atmosphere, where their interactions with gas particles, such as oxygen or nitrogen, set off spectacular bursts of light.
Although only a sliver of Saturn’s sunlit face is visible in this view, the mighty gas giant planet still dominates the view.
From this vantage point just beneath the ring plane, the dense B ring becomes dark and essentially opaque, letting almost no light pass through. But some light reflected by the planet passes through the less dense A ring, which appears above the B ring in this photo. The C ring, silhouetted just below the B ring, lets almost all of Saturn’s reflected light pass right through it, as if it were barely there at all. The F ring appears as a bright arc in this image, which is visible against both the backdrop of Saturn and the dark sky.
I’m trying to keep up with ESA’s images, as my regular bloggies would know I used to post this every week but I’m slacking nowadays. This weeks images show cyclone Debbie, Supernova remnant SNR 0509-68.7 and ESA’s ExoMars Rover.
