Rare Lunar Trifecta....

Courtesy: NASA
A rare celestial treat will colour the skies on Januay 31,2018, when a Blue Moon, a total lunar eclipse and a supermoon all rolled into one. NASA has even dubbed the event a "Super Blue Blood Moon," as it will occur near when the moon is at its closest point to Earth, a so-called "supermoon." There hasn’t been a triple lineup like this since 1982 and the next won’t occur until 2037.
The first event is a total lunar eclipse that happens on the morning of Jan. 31. This eclipse will be special! The moon will be both "super" and "blue," and if skies are clear, skywatchers in North America will be able to see all or part of the eclipse.
Blue Moon occur when two full moons happen in the same calendar month; blood moon occur when the moon passes into Earth's shadow; and supermoon happen when the moon's perigee — its closest approach to Earth in a single orbit — coincides with a full moon. In this case, the supermoon also happens to be the day of the lunar eclipse. According to, best place to see it will be in central and eastern Asia, Indonesia, New Zealand and Australia.
Blood Moon:
During a total lunar eclipse, though the Moon gets shadowed by the Earth, sunlight passing through the Earth’s atmosphere, break down in its constituent colours and the red part gets scattered by the atmosphere and falls on the Moon's surface, thereby making it take on a reddish copper hue. That’s why a totally eclipsed Moon is called a “Blood Moon”, as the colour of the Moon looks blackish-red.
A lunar eclipse can only happen at full moon. Only then is it possible for the moon to be directly opposite the sun in our sky, and to pass into the Earth’s dark umbral shadow. Most of the time, however, the full moon eludes the Earth’s shadow by swinging to the north of it, or south of it. For instance, the last full moon on January 2, 2018, swung south of the Earth’s shadow. The next full moon – on March 2, 2018 – will swing north of the Earth’s shadow.
Super Moon:
A super moon usually takes place every one to two years, when the full moon coincides with its closest approach during its monthly orbit to Earth. Because the moon has an elliptical orbit, one side - called the perigee - is about 48,280 km (30,000 miles) closer to Earth than the other side (the apogee). The term was coined by astrologer Richard Nolle in 1979. During the phenomenon, the full moon appears about 14 percent and 30 percent brighter that it would during regular full moons. When this Earth-Moon-Sun system occurs with the perigee side of the moon facing us, and the moon happens to be on the opposite side of Earth from the sun, causes the moon to appear much bigger and brighter in our sky than usual, and it's referred to as a supermoon - or more technically, a perigee moon.
Blue Moon:
Usually full moon happens approximately once a month, or every 29.5 days.A blue moon normally occurs about once every two and a half years. This month’s first full moon was on 1 January.
A Moon that actually looks blue, however, is a very rare sight. The Moon, full or any other phrase, can appear blue when the atmosphere is filled with dust or smoke particles of a certain size; slightly wider than 0.7 micron. The particles scatter the red light, making the Moon appear blue. This is known as Mie scattering, and can happen for instance after a dust storm, a forest fire, or a volcanic eruption.
Interestingly, while you search about “Super blood blue Moon,” in internet, you may see that it is happening after 152 years and the last time it happened was in March 31,1866. But this is true only for the Americas, not for everywhere on the globe. In Asia, the last Blue Moon and total lunar eclipse happened on December 30, 1982.
The moon is one of the most amazing objects in our solar system, and it had often helped us study our solar system. Total eclipses of the Moon are spectacular events and are easy to see with the naked eye. NASA scientists say the way the moon's surface responds during the eclipse can provide insights about where to land a rover for a future mission.
The best tip for anyone trying to see the eclipse is to get a clear view of the horizon and look in the west-northwest direction. It can be seen through the naked eye though using a telescope could make for a fun experience. Just step outside, look up at the sky, and enjoy! It's an astronomical trifecta which will occur once in someone’s life time... Don't Miss it...
For anyone who can't go out side, NASA has started its live stream of the total lunar eclipse that will occur with a blue moon, known as a Super Blue Blood Moon, for people to see the spectacular event unfold. Here you go:

Fidget Spinner - Toy Craze of 2017

The hottest toy of the season, fidget spinner, has made their way into the fingertips of many to help with anxiety attacks."Fidget spinners" are small, ball-bearing devices that the user can rotate between his or her fingers. Made up of a variety of materials from metal to plastic, designs varying anywhere from 2-5 propellers that surround the center bearing and when spun it maintains its momentum by continuing to spin the object. The most popular of the models happens to be the tri-spinner fidget toy.
Numerous studies discuss the benefits that fidgeting has on the body, how it boosts memory, focus and creativity. And a recent study published in the American Journal of Preventive Medicine found fidgeting can make you healthier. Fidget spinner are the biggest gadget trend of 2017. These aren’t just for kids either, individuals of all ages can benefit from using fidgets, but especially individuals with the following:
  • Anxiety
  • Autism or Aspergers
  • Sensory Processing Disorder (SPD)
  • Behavioral Problems
  • Inattention/Difficulty Focusing
  • Shyness/ Social Anxiety
Fidget spinners were invented by Catherine Hettinger, who showed her invention to Hasbro way back in 1997. The 62-year-old had a patent from 1997 until 2005, but was not able to afford the fee to renew her exclusivity to the gadgets, which was $400, the equivalent of around £310. No wonder why she stays away from scene!
A fidget spinner was launched as a toy that was mainly marketed as a stress relieving device. These are devices that are portable enough to fit in the palm of your hand.
How does it work? It spins around and creates a hypnotic effect. This is meant to relieve stress and anxiety as your brain is involved in a manner, which provides you comfort in stressful situations. Therefore, when an autistic child plays with a fidget spinner, the brain of the child is believed to release happy or stress relieving hormones. The continuous movement of the gadget helps in keeping the child focused on one activity which involves a great deal of concentration. Thus by using the fidget spinner, the children are expected to curb down the symptoms of autism which are mainly caused by hyper-sensitive sensory nerves. The tactile sensations, as well as the vision of things spinning steadily are reported to induce soothing feelings to the easily stimulated minds.
Spinners give your hands something constructive to do when you feel nervous.
Fidgets can take away the focus of tension (i.e. a conversation, a test, etc…) and instead re-directs it to the spinner.
Spinners restore some control back to the individual during perceived “out of control” situations, empowering them with more confidence and security.
One of the things which people like about fidget spinner is that it produces distinctive and unique imagery effects when being spun. Of cousrse therapeutic benefit similiar to the motion of fish in ponds or from staring at the bonfire can be obtained from observing the visualization produced by the spinner
Taking the fidgets for few spins can help easing the dreadful feelings inside our minds, because the ball bearings inside the body act as support to maintain the spin with the minimal efforts. The perpetual motions of the spinner induces the feelings of maintaining order and assurances that everything going on just fine.
Because spinners are a fun, unique fidget coming in all different sizes, shapes, and colors, many kids are curious about them and will strike up a conversation about them. Yeah , it can be used as a conversation tool..
As a mother, I think these are good toys for kids.These little gadgets may just keep your kids off the electronics and desiring to attempt tricks and be outside with these spinners to test what they can do. Anything that helps keep kids off electronics must be a good thing, right?!
Some of the points to keep in mind regarding fidget spinners are:
  • Fidget Spinner
    The bearings are removable and can cause a choking hazard if children are not monitored.
  • Most teachers agree that they serve more as a distraction in a classroom setting than a means by which to center focus.
  • When you’re looking at a fidget spinner, your vision dulls and blurs around you, causing you to get a little dizzy from having wired off into some whirl of the spinner. That’s not a good thing because, for some people it could take time to regain your vision to its full potential and it can actually cause your eyes to water and your head to ache and remain heavy for long after you have stopped using the object.
  • It encourages a sedentary lifestyle as you can sit for hours just spinning. Fidget spinners encourage you to be seated which is not good for your health..
  • There is no doubt that fidget spinners are great for those 5-minute breaks from your daily life chores. But, have you not heard the saying that too much of anything is bad for your health? The same can be said about a fidget spinner. If you sense the fidget spinner is distracting you or your child more than it’s helping, you’re probably right in throwing them away...
