The next Blue Moon will be on May 21, 2016. It’s a seasonal Blue Moon, the third of four full moons between the March equinox and the June solstice of 2016. Read about the various kinds of Blue Moons, and how often they occur, here.

We don’t often see such contrast in the sky, but this we had to stop and snap on the iPhone.
Where is the starlit band of the Milky Way on these May evenings? That luminous band of stars crossing the dome of sky is nowhere to be seen during the evening hours in May. Why? The disk of our Milky Way galaxy is shaped like a pancake. On May evenings, the plane of the pancake-shaped galactic disk coincides with the plane of the horizon. Because the Milky Way rims the horizon in every direction in the evening in May, we can’t see this roadway of stars until later at night right now.
The Sonic Hedgehog gene drives embryonic development of mammal limbs and shark gills. Could our limbs have evolved from gills?
Jesse Jackson saw this sun pillar near Tucson, Arizona. “Talk about a ray of sunshine,” he said.
In 2007, a faint star in the constellation Bootes the Herdsman made astronomical history. An international team of astronomers, led by Jean-Francis Donati and Claire Montau of France, caught the star Tau Boötis flipping its north and south magnetic poles. These astronomers had been mapping the magnetic fields of stars. It was the first time a magnetic reversal had been observed on any star other than our sun.
Breakthrough Starshot seeks proof of concept for a 100-million-mile-per-hour mission – using light-propelled nanocrafts – to reach the nearest star in 20 years.
Alpha Centauri is the nearest star system to our sun at 4.3 light-years away. That’s about 25 trillion miles (40 trillion km) away from Earth – nearly 300,000 times the distance from the Earth to the sun. How might we travel to Alpha Centauri, the next-nearest star? And how long would it take to get there? Read about star travel via conventional propulsion, warp drives, and more.
You might spot it after sunrise on April 30, high in the sky. Did you know a last quarter moon is slightly fainter than a first quarter moon? Learn why here.
No, Earth’s magnetic field did not collapse for 2 hours on April 23. The erroneous story – which is still spreading – came from a glitch in a computer simulation.
