TED Talks With Henry Lin: What We Can Learn From Galaxies Far, Far Away

From TED:

In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe’s largest pieces, says the Intel Science Fair award winner, we can learn quite a lot about scientific mysteries in our own world and galaxy.

An “incredible mix of ingredients” came together to make this shot possible, writes Fizza Verdinelli, a member of our Your Shot community. Verdinelli had been on Mount Bromo in Java, Indonesia, during sunrise and had descended to find a unique sort of photographic opportunity. The men, he writes, were there “just to earn some easy money by helping tourists to hike the volcano, but they [were] so real and full of energy at the same time.” Rising fog, the low light of the sun, and the dust thrown up by the running horses presented an “amazing situation.”

NASA’s Astronomy Picture Of The Day: Flying Past Pluto

From NASA:

Explanation: What would it look like to fly past Pluto? The robotic New Horizons spacecraft did just this in late July and continues to return stunning pictures of the dwarf planet. Some well-chosen flyby images have now been digitally sequenced to create the featured video. The animation begins by showing New Horizon’s approach to the Pluto system, with Pluto and its largest moonCharon orbiting a common center of mass. As the spacecraft bears down on Pluto uniquely, surprising surface features are nearly resolved that, unfortunately, quickly rotate out of view. New Horizons then passes just above and near a large, fascinating, light-colored, heart-shaped, and unusually smooth region now known as Tombaugh Regio. The spacecraft then pivots to look back at Pluto’s night side, seeing an encompassing atmospheric haze. Finally, Pluto fades away in a final sequence illustrated with the orbits of many of Pluto’s smaller moons. Although humanity has no current plans to return to Pluto, the New Horizons spacecraft may well be directed next to fly past an asteroid currently known only as 2014 MU69.
