Supermassive Black Hole

Normally black holes do not emit light. But when X-ray is passed to it, it lightens up. Star Heida is the one that is recently been discovered through X-rays. The most astonishing fact about it is its location not present at the center of galaxy like other black holes. Furthermore it is a recoiling supermassive black hole. Recoiling black holes are a good source for research in finding how supermassive black holes are formed at the center of galaxies. So this black hole will be a lot worth. There is more possibility of finding more supermassive recoiling black holes. Researchers are now going to use NASA’s Chanda satellite to find more.

A Black hole


A black hole can be defined just like why an object looks black. Yes because it absorbs all lights and doesn’t allow any light to reflect back so it looks black. Likewise black hole is any region in space which doesn’t allow light to escape.

The picture is taken accurately with black hole in front of Large Magellanic cloud. Large Magellanic Cloud is a galaxy which is irregular in shape. It can also be written as LMC. One more interesting fact about LMC is that it is the third closest galaxy to milky way with a mass of ten billion times of our sun.

Around it small small rings can be seen. These are Einstein Ring that is produced due to the affect of gravitational lensing. Whenever light coming from a bright source bends around a massive object, gravitational lensing occurs.

This beautiful image is just a small sample of God’s creation. There are much more to be seen.

Glory-NASA's eye on sun

It has been a confusing question in the minds of scientists and researchers that whether sun’s light and heat energy change? And whether it varies in such an extent that it has got a capacity to change earth’s climate?

For this NASA sent its first satellite instrument-radiometer. Radiometer has a capacity of measuring the amount of light that strikes the earth’s atmosphere. This light can also be termed as total solar irradiance. It had shown that sun’s light has changed over decades.

Without it, it would have been difficult to discover how much energy the sun emits.Still there lays a question unanswered- whether the irradiance has been changing throughout the 3 11-year cycle? If this question gets an answer then it will help in getting knowledge about climate change. Glory will be launched in November.

A Girl Having Third HEART

Have you heard of heart transplanted TWO times? Ya… this “two” in the case of heart transplantation is not common furthermore being still living is so rare and supernatural.

Laila

Laila-it is the name of cyclone that is the cause of rainfall in the eastern coastal areas of India. Rain is what that is mostly desired by people after a long term summer. The chillness in the atmosphere refreshes out minds. Farmers get excited.

Though rain is mostly desired but it is also causing many causalities. This harsh cyclone is prevalent in Bengal-bey. It has affected the communication and network area in Andra Pradesh.

Many fishermen are very disturbed because they cannot go for fishing. It makes difficult for those who are totally dependent on fishing for their living.

It is said that this laila is going. But it is doubted that it may come once again. So everyone especially fishermen have to be more alert.

Facial expressions and movements

Sometimes it happens that we say something and our movements say something else. It happens when we try to hide something or we do not want the other person to know something. But it may happen that, the person might get our mind from our movements and gestures.

Reports tell that if you just watch the movements without noticing the facial expressions and if all the audios are made mute, you can really guess right about 80%. Its amazing but its true.

Likewise facial expressions are also very important. They express joy, relief etc. Some people express more things by facial expressions and some do not even show a single thing. That’s the wonder of God’s creation-variety. Everyone differ from one another.
