Penumbral Lunar Eclipse Live October 18th
On Friday October 18, the Full Moon will venture into Earth’s outer or penumbral shadow, producing an eclipse. Slooh, the Community Observatory, will track the Moon with its Canary Islands Half-Meter telescope, showing real-time as well as time-lapse views of the eclipse, accompanied by live narration from Slooh’s Paul Cox, and astronomer Bob Berman.

Tonight’s Sky: October 2013
Your guide to constellations, deep-sky objects, planets and events, Tonight’s Sky, Highlights of the October Sky
Venus hovers low over the southwestern horizon in the early evenings of October. Use a telescope to get a better view of the planet.
Constellations and Deep-Sky Objects
Pegasus, the great winged horse of Greek mythology, prances across the autumn night sky. His body is denoted by a large area of stars known as the “Great Square.”
Pegasus hosts 51-Pegasi, the first Sun-like star known to have an extra-solar planet.
The brightest corner of the Great Square, Alpheratz, is also the brightest star in the constellation Andromeda. In Greek mythology, this princess was chained to a rock near the sea to appease a sea monster.
Within Andromeda’s boundaries, look for M31, the Andromeda Galaxy, an island of billions of stars. On a clear, dark night it appears as a faint smudge of light.
Approximately 2.5 million light-years away, M31 is the closest spiral galaxy to our own Milky Way Galaxy and the most distant object you can see with your eyes alone. Binoculars and small telescopes reveal M31’s glowing nucleus and spiral arms.
A smaller companion galaxy, M110, appears as a faint spot near the large galaxy. The Andromeda Galaxy is slowly pulling in, and will eventually consume, another one of its small companion galaxies, M32.
Jupiter rises around midnight to dominate the sky throughout the morning hours.
Use binoculars or a small telescope to admire the giant planet’s features. Before sunrise, look for Mars above the eastern horizon. During mid-month it dances close to bright star Regulus. A telescope will help you to glimpse some of the planet’s features.
An interesting meteor shower peaks on the night of October 21st to 22nd.
After midnight, look to the east, where the constellation Orion is rising. Every few minutes you may spy a tiny remnant of Halley’s Comet burning up high in the atmosphere. This is the Orionid meteor shower.
A penumbral eclipse of the Moon occurs on the 18th, visible to watchers in North and South America, Africa, Europe, and most of Asia. The Moon will darken slightly as it passes through the outer edges of Earth’s shadow.
The night sky is always a celestial showcase. Explore its wonders from your own backyard.

Autumnal Equinox Live From Canary Observatory
Earth will stand perfectly sideways to the Sun on Sunday, September 22, at 4:44 EDT. At that moment, the Sun will hover directly above the equator, and numerous celestial oddities will occur — even if most people simply know it as “the start of fall.” SLOOH will have a team of astronomers and production personnel on hand live at Canary Islands, with live views from their observatory site, to discuss the myths and realities of the equinox. The show begins live at 4:30 PM EDT, 1:30 PM PDT Sunday.
Shine on Harvest Moon
Wednesday, September 18, 2013 – 7 PM PDT / 10 PM EDT / 02:00 UTC (9/19)
Join the Slooh Team to celebrate and discuss what we call a Harvest Moon, which is the Full Moon nearest the autumnal equinox. We’ll be watching wonderful real-time images direct from Slooh’s Canary Islands observatory and through our partner facility in Prescott, Arizona. Paul Cox, Bob Berman, and Matt Francis will join the broadcast
Bright Nova Appears in DelphinusBy Steve Owens @Darkskyman on twitter. See the original article here
Last night a bright nova was discovered in the constellation of Delphinus. It’s bright by nova standards: you normally need telescopes to see novae but this can can be seen with the naked eye – just! – and is easily spottable through binoculars. At the time of writing it has been observed at magnitude 6.3 by Koichi Itagaki, of Yamagata, Japan, and at magnitude 6.0 by Patrick Schmeer, of Bischmisheim, Germany. This means that under dark skies, free from light pollution, with good seeing conditions and good eyesight, it’s within the limit of human eyesight. If you’re in a city though, or if your eyesight isn’t perfect, you’ll need binoculars. Read the rest of this entry »
Perseid Meteorwatch – Saturday 10th to Monday 12th of August 2013
The Perseid meteorwatch 2013
The Perseid meteorwatch 2013 starts on Saturday 10th and runs each evening until Monday 12th of August 2013 @VirtualAstro with the help of many more people, will be holding a Twitter #Meteorwatch for the Perseid Meteor Shower.
Everyone is welcome to join in, whether they are an astronomer, have a slight interest in the night sky or have a passing interest and just wonder?
The Perseids are the highlight of the astronomical calendar and a must see! They are ideal for those who want to see a meteor/ shooting star for the first time.
UK ISS Pass details for August 2013
The International Space Station (ISS) is back over UK skies with some great passes during August 2013. There is a special bonus this time as the passes take place during the Perseid Meteor Shower - you may see shooting stars too!
The ISS is the largest Space Station/ laboratory ever built orbiting the Earth, it can be spotted with the naked eye at certain times as it orbits the planet at 17500mph at an altitude of roughly 200 miles.
