The sharp eye of NASA’s Hubble Space Telescope has captured the tiny moon Phobos during its orbital trek around Mars. Because the moon is so small, it appears star-like in the Hubble pictures.
Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a time-lapse video showing the diminutive moon’s orbital path. The Hubble observations were intended to photograph Mars, and the moon’s cameo appearance was a bonus.
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
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.
An exciting discovery from NASA that the world is talking about (via Sparkonit)
Seven Earth-size planets that could potentially harbor life have been spotted orbiting a dim dwarf star called Trappist-1, which is located at 39 light-years away in the constellation Aquarius. According to NASA, all seven could potentially support liquid water, on the surface, but only three represent the “holy grail for planet-hunting astronomers,” because they are…
