Asteroid containing minerals worth billions set to pass close to Earth

Asteroid containing minerals worth billions set to pass close to Earth



A rather valuable asteroid has passed by Earth over the weekend.
Asteroid UW158 passed by at six times the distance between Earth and the moon - still relatively close for a future asteroid mining mission.
So what makes this asteroid so valuable then?
Well, the body, which is just under a kilometre in diameter, has a core made out of platinum.
In fact, Forbes reported that the platinum core is worth roughly five trillion dollars.
Work is already underway to develop asteroid mining, with private firm Planetary Resources testing technology on the International Space Station this week.
The company's Arkyd 3 Reflight (A3R) spacecraft was launched from the ISS's airlock on a 90-day mission.
A3R is a testbed for future spacecraft that will travel to asteroids, being used to test navigation, avionics and software.

So hopefully by the time the next valuable asteroid flies past Earth, we're in a position to do more than just point it out

How do mosquitoes find food? First, they smell you, scientists say

How do mosquitoes find food? First, they smell you, scientists say

The researchers found that mosquitoes rely on a variety of senses to find their meals in a process they divided into stages: first they pick up a scent, then they follow a visual cue, and once they are close enough to the target they sense its body heat. The scent that alerts mosquitoes to the proximity of a potential target is not that of blood, but of carbon dioxide, the gas we exhale. Mosquitoes can smell the gas from as far as 30 feet away, University of Washington researcher and co-author on the paper Jeff Riffell explained in a news release.
 “Carbon dioxide is the best signal for a warm-blooded animal, and they can sense that from up to 30 feet away – quite a distance,” Mr. Riffell said. “And then they start using vision and other body odors to discriminate whether we’re a dog or a deer or a cow or a human. That may be how they discriminate among potential blood hosts.”
In the study, mosquitoes were put in a wind tunnel that was plain and empty, except for a black dot on the floor to serve as a visual stimulus. The introduction of carbon dioxide into the tunnel triggered the mosquitoes’ instinct to search visually for food, Riffel said. “When we gave them the odor stimulus, all of the sudden they were attracted to this black dot,” said Riffell. “It’s almost like the carbon dioxide gas turned on the visual stimulus for the mosquitoes to go to this black dot.” "The unfortunate conclusion is that it's very difficult to escape mosquitoes,” he said.

MOON, VENUS AND JUPITER APPEAR VERY NEAR TO EACH OTHER


MOON, VENUS AND JUPITER APPEAR VERY NEAR TO EACH OTHER



Tomorrow, the Moon, Venus and Jupiter - the second, third and fourth brightest objects of the sky after the sun - will appear to be clustered together. View the sight from any location with a clear view of the west, with as few horizon obstructions as possible.

Look to the western sky at dusk tomorrow, and you may see three celestial bodies clustered together in a divine meeting.
The Moon, Venus and Jupiter - the second, third and fourth brightest objects in the sky after the Sun, and in reality millions of kilometres apart, will appear to be almost side by side.
The crescent Moon will appear as just a small silver sliver, and look as though it is hanging nearer to Jupiter. Even though Venus is smaller than Jupiter, it is brighter, due to its closer position to the Sun.
During that conjunction, the two planets were separated by a distance less than the diameter of a full moon, with star-gazers able to "block" both Venus and Jupiter behind their little finger, said the United States' National Aeronautics and Space Administration.

Venus, the second planet from the Sun, is 77 million km from Earth, and Jupiter, the fifth planet from the Sun and the solar system's largest, is 909 million km away.

While it is not all that rare for the two planets to get so close to each other, the viewing angle at many latitudes and the time of day made the conjunction a particularly spectacular event, which some star-gazers have likened to the biblical "Star of Bethlehem" that led the magi to baby Jesus.

Many have referred the event as ‘Star of Bethlehem’ that led to the birth of Jesus. As per astronomers, the way planets were arranged were almost same to the way they were 2,000 years ago when the Christ was born.
