You must have heard about asteroids coming close to Earth and about to collide. Looks like a fairy tale.
But this is true.
February 4, 2018 which is less than a week from now will witness this when asteroid called “2002 AJ129” will zip past Earth at a speed of 1 lakh kmph and is designated potentially hazardous by NASA scientists.
This is potentially hazardous because the asteroid which is 1.1 Km wide will fly about 42 lakhs Km away from Earth which is considered very close in space terms.
To give an idea on this distance Moon is 3.84 lakhs km away from Earth.
In the early years of its formation asteroids had collided with Earth about 4 billion years ago that resulted in extinction of about 75% species of plants and animals including dinosaurs. This also resulted in climate change.
The proof of such a disaster is The Chicxulub crater located in Mexico’s Chicxulub town.
There are about 190 craters on Earth because of such disasters happened earlier. Out of this 190 following countries have the maximum craters:
- South Africa- 4
India has 2 craters one in The Lonar Lake in Buldhana district of Maharashtra and another one in Shivpuri district of Madhya Pradesh. These craters are believed to be 52,000 to 5, 70,000 years old and have a diameter of 11 kms.
Possibility of operating all flights on electricity is being explored and Norway will become the first county in the world to have all electric flights operating in domestic zone including other Scandinavian countries.
Norway has set Year 2040 as the deadline for all electric flights at least the domestic ones.
Chief executive Dag Falk-Peterson of Avinor, the public operator of Norwegian airports said “we think and wish to make all flights lasting up to 1.5 hours electric so that it becomes a solution and not a problem for the environment”.
This way the cost of operating flights will almost be halved resulting in nose diving of ticket price. People will travel more and will have more fun.
Norway is the largest oil and gas producer in Western Europe but is equally focused on transport sector and is a world leader in electric transport.
Falk-Peterson told the media that use of intermediary technologies, such as bio fuels and hybrid fuel would be a challenge. These challenges need to be addressed for making electric flights successful.
You love dry cleaned clothes as it gives fresh looks, removes stains and body odour.
But chemical PERC (Perchloroethylene) used in dry cleaning is globally recognized as a health hazard and poses threat to the environment.
A recent survey of about 79 dry cleaning facilities in Delhi and Kolkata in India shows that none of the facilities were aware about the danger of PERC whereas International Agency for Research on Cancer claimed PERC being a carcinogen.
The survey found concentration of as low as 1.3mg/kg to as high as 101mg/kg and suggests that it is readily absorbed by inhalation, skin contact or ingestion.
International reports have demonstrated incidences of respiratory failure and deaths in extreme cases.
Multiple health hazards includes irritation of the nose and throat, depression of the central nervous system with symptoms such as drowsiness, dizziness, giddiness, headache, nausea, loss of concentration, confusion and unconsciousness resulting from short term inhalation of very high levels of tetrachloroethylene.
So next time think twice before getting your cloth dry cleaned and should be done only if no other alternative is available.
Wish you a very good health!

Have you ever seen aquatic plants that are sprawling grounds for Alligators?
These were spotted at the side of Salado river, a tributary of Paraguay River and is an off the beaten place that provides a hiding place for small Alligators.
These are giant round water lilies spanning over 1.5 meters (approx 5 feet) that was believed to be extinct about 12 years ago and have given a boost to tourism.
These wonderful plants which are a queen of water lilies are native to Paraguay which and appear every third or fourth southern hemisphere summer.
The scientific name of this plant is Victoria Cruziana. These are also called Alligator Lilies because they are large enough to hide small Alligator.
These lilies are very good in tea making as these fight asthma and bronchial issues and hence authorities have issued warnings to fine anyone who tries to harvest this plant.
Have you ever heard anyone falling from the tree because of chilly weather?
Iguanas are falling from the trees in USA due to chilled weather.
Iguana is a large arboreal tropical American lizard with a spiny crest along the back and greenish coloration which are found in Mexico, Central America, South America and the Caribbean. These can even be found in Southern belt of USA.
Florida, a south eastern state of USA has become so chilled that Iguana is falling from the tree like overripe mangoes once it climbs it due to bad weather. Iguana is a cold blooded lizard but chill factor has forced Iguana to loosen its grip and fall on the surface.
These herbivorous creatures fall once the temperature nose dives to 10 degrees Celsius. Fellow reptiles-sea turtles also stiffen when the temperature drops.
Residents are advised not to come near Iguanas as they may feel threatened and may bite once they warm up.
