Stargazing From the International Space Station at May 17, 2016

Astronauts aboard the International Space Station (ISS) see the world at night on every orbit — that’s 16 times each crew day. An astronaut took this broad, short-lens photograph of Earth’s night lights while looking out over the remote reaches of the central equatorial Pacific Ocean. via NASA http://ift.tt/1rRGKHd

Hubble Spies a Spiral Snowflake at May 13, 2016

Together with irregular galaxies, spiral galaxies make up approximately 60 percent of the galaxies in the local universe. However, despite their prevalence, each spiral galaxy is unique — like snowflakes, no two are alike. This is demonstrated by the striking face-on spiral galaxy NGC 6814. via NASA http://ift.tt/1TKk7dX

Hubble Spies the Barred Spiral Galaxy NGC 4394 at May 06, 2016

Shown in this Hubble Space Telescope image, NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. via NASA http://ift.tt/1rZSvvv

Light Echoes Used to Study Protoplanetary Disks at April 26, 2016

This illustration shows a star surrounded by a protoplanetary disk. A new study uses data from NASA’s Spitzer Space Telescope and four ground-based telescopes to determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Researchers used a method called “photo-reverberation,” also known as “light echoes. via NASA http://ift.tt/26rHbbb
