Look out for the ‘super blue blood Moon’ on the rise
Look out for the ‘super blue blood Moon’ on the rise
The celestial show is the result of the sun, Earth, and Moon lining up perfectly for a lunar eclipse just as the Moon is near its closest orbit point to Earth, making it appear “super” large.
It is the second full Moon within the same month, a phenomenon called a “blue” Moon which has nothing to do with its color.
The “blood” in the name comes from the reddish brown color the Moon takes on when Earth enters between it and the sun, cutting off the light rays that usually brighten the lunar surface.
Thousands gathered at Los Angeles’ Griffith Observatory, which opened its doors at 3:30 am (1130 GMT) to a crowd expected to reach 2,000.
Some had waited in line since 10:00 p.m. the night before, hoping for a choice viewing spot.
Coffee was on sale, and many science buffs brought their own telescopes to set up on the lawn.
The eclipse began around 3:45 am, as a black shadow began to devour one corner of the gray-white Moon.
An hour later, the lunar surface was plunged into darkness, known as totality.
Then, rusty tones began to sheath the Moon, reflecting the light of all the sunrises and sunsets on Earth at the same moment.
The extreme east of Africa, the Middle East and Asia, Russia, Australia and New Zealand could enjoy the spectacle on Wednesday night, as the Moon rises there.
People in Hawaii, Australia and eastern Asia should be able to follow the full eclipse from beginning to end, said NASA.
But most of South America, Africa and Europe, where the alignment occurs in the middle of the day, will miss out on the show.
The last “super blue blood moon” occurred on December 30, 1982, when it was seen in Europe, Africa and western Asia.
For North America, the last time was in 1866.
This time around, viewing will be a challenge for those on the US East Coast. The eclipse begins just as the Moon is setting in the west and the sun is rising in the east.
Moon-watching parties for the one-hour-16-minute eclipse were advertised up and down the US West Coast. But people outside the path of totality, or whose view was obstructed by cloudy weather, could follow the event live via NASA.gov.
If you miss this one, the next blue moon total lunar eclipse will happen on December 31, 2028, though it won’t be quite as large since it will not be as close to Earth.
Another will occur on January 31, 2037.
“The red color during a lunar eclipse is very distinctive and it’s a rare treat to be able to see a blood red moon,” said Brian Rachford, associate professor of physics at the Embry-Riddle Aeronautical University.
“One of the great things about a lunar eclipse is you also don’t need any special equipment to see it. Anyone can go outside and look at the moon.”
King Abdul Aziz City for Science and Technology unveils self-guided Black Shark boat at 38th GITEX Technology Week
- These trucks are equipped with electronic pairing technologies, which effectively improve the shipping and distributing of goods, reduce human error
JEDDAH: King Abdul Aziz City for Science and Technology (KACST) has unveiled its Black Shark self-guided boat at the 38th GITEX Technology Week in Dubai. The vessel, which can carry out coastal surveillance and many other tasks, was developed in collaboration with Taqnia for Robotics and Smart Systems.
The development of the craft is part of a KACST initiative to localize and transform transport technology and logistics, to help achieve the aims of Vision of 2030.
The boat includes sensor systems that allow it to monitor and create a 3D map of a 200-meter area surrounding the boat, and automated control technology that gives it the ability to navigate independently and avoid collisions without human input. It can also be equipped with a flexible range of weapons, acting as a firearms platform that uses gyroscopic self-balancing technology. It has the ability to survey beaches at a range of 15 kilometers, in addition to accurately identifying its precise location with a margin of error of less than 20 centimeters using differential GPS, as well as specifying, monitoring and tracking targets.
The Black Shark also has long-range radar that covers up to 150 kilometers, and a telecommunication system to track its location, monitor its status and connect to multiple domains through command centers that allow wireless communication and remote control. It is fitted with a digital camera powered by electro-optic and infrared technology that can produce HD-quality video, and also has night vision capability.
As part of its initiative to develop transport technology and logistics, KACST has also worked on automated control technology, included self-driving heavy-duty trucks, with the University of California, Berkeley. These trucks are equipped with electronic pairing technologies, which effectively improve the shipping and distributing of goods, reduce human error, preserve resources, and reduce harmful emissions and fuel consumption.
The same technology can also, for example, transform a four-wheel-drive vehicle into a remote-controlled vehicle equipped with video cameras, infrared technology, a microphone and a control device wirelessly connected to a command center, where an operator can guide it using images from the video cameras.
