Night side of Earth. Is Earth totally dark when it’s night for you? No. Earth is always half illuminated by sunlight. Notice the crescent of illumination on one edge in this photo. If you were on the other side of Earth when the images used in this composite were acquired, you’d see Earth shining brightly in reflected sunlight, aka daylight. Image via NASA/NOAA.
Question: Will Earth experience six (or three) days of darkness in December, 2014?
We at EarthSky have received many questions already about the so-called days of darkness supposedly announced by NASA and supposedly coming up in December, 2014. This rumor has spread like wildfire, as did the same rumor in 2011, which called for days of darkness caused by the erstwhile Comet Elenin. Is it true? Of course not.
The earthquake swarm is taking place in a sparsely population area in northwestern Nevada
UPDATE NOVEMBER 7, 2014. Nevada Seismological Laboratory at University of Nevada, Reno joins with other federal, Washington and Oregon agencies to provide this update:
A swarm of earthquakes in a sparsely populated area of far northwest Nevada that began on July 12, 2014, has increased in intensity over the past several days. This activity is located about 40 miles southeast of Lakeview, Ore., and 40 miles northeast of Cedarville, Calif. During the past three months the Nevada Seismological Laboratory, in collaboration with the U.S. Geological Survey and seismic networks in Washington and Oregon, has recorded 42 earthquakes larger than magnitude 3, and about 550 earthquakes larger than magnitude 2.

This means planets are now emerging in the disk, and they are in the process of sweeping their orbits clear of dust and gas. Image via ALMA (NRAO/ESO/NAOJ); C. Brogan, B. Saxton (NRAO/AUI/NSF)
The recently upgraded ALMA telescope in Chile has obtained what they say is the best-ever image of a planet-forming disk, around the sunlike star HL Tau, located 450 light-years away in the direction of the constellation Taurus the Bull. It is an impressive image and gives us a glimpse of the process by which planets are born in orbit around their stars.

Typhoon Nuri in the Western Pacific will likely cause extreme weather for the Northern Pacific and North America in the next 5-10 days.

Of the things that my colleagues and I hoped to see on our trek in Bhutan, only one was missing: Ice.

How many times have you watched Close Encounters of the Third Kind, or Independence Day and wondered if what happened in those films could ever really occur? That day may be getting closer as things start to get interesting in the search for extraterrestrial life.
After a rare night of comfortable camping sleep, you are prematurely awakened by a repetitive drumming sound. Not loud enough to be a jackhammer, too rhythmic to be other campers assembling their tent – what could be the cause? In more parts of the world than not, the culprit is likely a woodpecker, a bird that makes a living drilling holes with its beak, primarily in wood.
How do these feathered lightweights carve out dents large enough to nest in without the aid of power tools and with no apparent damage to their bird brains? It turns out it’s all in their heads.

The Chinese Chang’e 5 test vehicle captured this extraordinary view of Earth over the far side of the moon on October 28. From Earth, the phase of the moon was a waxing crescent. From the moon, the Earth was in a waning gibbous phase. More detail about features visible on this photo on the far side of the moon, inside.
Marfa lights – or not – from papiblogger.com.
Ghost lights used to be called will-o-the-wisps. They were a weird glow over swamps or bogs. Nowadays, people report strange lights in the sky in all sorts of places. Some are more famous than others. The ghost lights closest to me are in the desert-like Davis Mountains near Marfa, Texas, but you can also see them in the Brown Mountains of North Carolina, and other places in North America. There are modern, very ordinary explanations for these lights. Yet people still love to try to spot them. Follow the links inside to some samples of North American ghost lights.
