Representatives with the online Slooh Community Observatory are hoping to capture some amazing footage of the "shooting stars" during a webcast tonight (Oct. 21). You can watch the broadcast — which will feature views from telescopes in the Canary Islands and Arizona — live directly through Slooh (http://live.slooh.com/) starting at 8 p.m. EDT (0000 Oct. 22 GMT). Slooh experts will be available to discuss the science of the shower, and they have also set up a way for viewers to hear the ionization of the meteors as they streak through the atmosphere. You can also see the meteor shower webcast live on Space.com.
"The Orionids are usually the year’s third-richest meteor shower," Slooh astronomer Bob Berman said in a statement. "Not to mention that they zoom away from one of the best known and easily recognized constellations. But this year they’re particularly conspicuous because, unlike the August Perseids that unfolded under a full moon, and the December Geminids, which will also be diminished by moonlight during half the night, the moon will be totally absent for the 2014 Orionids. It should be quite a nice show."

The world is falling behind in a desperate race to gain the upper hand over the deadly Ebola outbreak, a top UN official has warned.
The three hardest-hit countries are Liberia, Sierra Leone and Guinea.
"Ebola got a head start on us," said Anthony Banbury, head of the UN Mission for Ebola Emergency Response (UNMEER).
"It is far ahead of us, it is running faster than us, and it is winning the race," he told the UN Security Council in New York, by remote link from UNMEER headquarters in Ghana.
"If Ebola wins, we the peoples of the United Nations lose so very much," he said.
"We either stop Ebola now or we face an entirely unprecedented situation for which we do not have a plan," Mr Banbury stressed.
He said that with infection rates rising exponentially every day, UNMEER will need 7,000 beds for treatment.
However, to push back the spread "we must defeat Ebola and we must do it fast," he said.
"With every day that passes, the number of sick people increases.
"Time is our biggest enemy. We must use every minute of every day to our advantage and that is what UNMEER is doing."
WHO assistant director general Bruce Aylward said the epidemic "could reach 5,000 to 10,000 cases per week by the first week of December", but described his figures as a working forecast.

Princeton University researchers were able to examine an iron wire just one atom thick, utilizing a scanning-tunneling microscope. On the thread, they spotted a location on the ultra-thin thread, where the probability of finding the elusive particle was high, confirming an 80-year-old theory.
Ettore Majorana proposed the idea that these strange particles could exist in a theory proposed in the 1930's. The theoretical particle was named after the physicist, but was not observed in nature until now.
Fermions are a class of subatomic particles that are one group of the building blocks of matter.
Investigators utilized an ultrapure lead crystal, which naturally develops thin surface ridges, as a mold for the wire. Iron atoms placed inside one of the ridges formed into a thin wire, just one atom wide and three atoms thick. This wire, along with its attendant lead cast, were placed under a microscope, standing nearly two stories tall, floating to avoid vibrations. The metal piece were then cooled to 457 degrees Fahrenheit, just above absolute zero. The microscope detected an electrically-neutral signal at the end of the nanowire, a distinctive sign of Majorana fermions.
"This is the most direct way of looking for the Majorana fermion since it is expected to emerge at the edge of certain materials. If you want to find this particle within a material you have to use such a microscope, which allows you to see where it actually is," Ali Yazdani, professor of physics at Princeton University and leader of the research team, said.
Matter and anti-matter usually annihilate each other when they meet, releasing vast amounts of radiation in the process. Unusually, in Majorana fermions, this dichotomy results in a highly-stable particle. This could allow the unusual particles to be utilized in future technology. This research could lead to new computers based on the laws of quantum mechanics, which would operate at much faster speeds than current technology.
A video detailing the new discovery is available on the Princeton University Vimeo channel.
The simple iron and lead construction of the detector could allow other researchers to quickly and easily recreate the results of the experiment, provided they have access to a suitable scanning-tunneling microscope.
Discovery of the Majorana fermion was detailed in the journal Science.

Astonishing photos were captured Saturday which showed the massive marine mammals “hauled out” onto the shore, the Associated Press reports.
The phenomenon was spotted about 5 miles north of the Eskimo village of Point Lay during the National Oceanic and Atmospheric Administrations’s annual arctic marine mammal aerial survey, which was conducted in conjunction with the Bureau of Ocean Energy Management.
Walruses — unlike seals — are unable to swim in the ocean continuously and must find a places to rest. They typically mount up on giant chunks of floating ice, but the recent rise in our planet’s temperature as sent the mammals scattering to find new places to lounge.
“It’s another remarkable sign of the dramatic environmental conditions changing as the result of sea ice loss,” said managing director of the World Wildlife Fund’s Arctic program, Margaret Williams.
The annual low point of the sea ice this summer was the sixth smallest on record since satellite’s began monitoring its progress in 1979, according to the AP
“The walruses are telling us what the polar bears have told us and what many indigenous people have told us in the high Arctic, and that is that the Arctic environment is changing extremely rapidly and it is time for the rest of the world to take notice and also to take action to address the root causes of climate change.”
