When this flight paths of starlings video by artist and professor Dennis Hlynsky went viral, it sparked a lot of questions for us: How did he make the visualizations? How do the starlings move quickly as a flock? What makes other groups of animals move the way they do?
In Micromigrationsfrom The Atlantic, Hlynsky discusses his own questions as we observe the water striders, ants, starlings, vultures, crows, and little white flying bugs that continue to inspire his curiosity and his work.
Watch the flight paths of starlings as they make computer-assisted trails across the sky above the Seekonk Speedway in Massachusetts. Artist Dennis Hlynsky filmed them (and others) with a Lumix GH2 and then used After Effects to make their paths more visible from their own visually-echoed image. A time-lapse of sorts…
How can we know the size, composition, and atmospheric makeup of distant exoplanets? NASA explains the details in this Alien Atmospheres video.
By observing periodic variations in the parent star’s brightness and color, astronomers can indirectly determine an exoplanet’s distance from its star, its size, and its mass. But to truly understand an exoplanet astronomers must study its atmosphere, and they do so by splitting apart the parent star’s light during a planetary transit.
"Physics told me some crazy stuff. Say, I’m not just sitting here doing nothing. I’m actually fighting against Earth’s gravity. And I’m not sitting still. I’m spinning at a thousand miles per hour, or even more than that… 67 thousand miles per hour, if you count the rotation of the Earth around the Sun…"
