BITCOIN WALLET DEVICES IN DANGER OF HACKING

Bitcoin is a digital crypto currency, to manage this currency we require some devices known as Bitcoin wallet devices.
Bitcoin require secure and private devices to handle but scientists reveals under their study that all bitcoin devices have security weak spot.

Researchers at the University of Edinburgh in the UK carried out in depth security analysis of all popular models of Bitcoin wallet. They created a simple harmful software or malware, which was able to hack these wallets i.e. to intercept, messages between hardware wallets and also easy to access Bitcoin funds to divert into different accounts.
But on the bases of tests, researchers proposed a fix for improving the security of such systems. This would encrypt messages sent between Bitcoin wallets and computers, making them more secure. Their fix can secure every model of bitcoin hardware against hackers.

"A wallet should protect not our money, but also our privacy. It was surprising to discover how easy it is to access a user’s funds, even when sophisticated hardware is incorporated. Unfortunately, there is no silver bullet when it comes to protecting financial digital assets – we need to ensure that all components of the system are equally protected and interact in a secure way."

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Some of the most amazing nebula pictured by Hubble in Milky Way Galaxy The Eagle Nebula’s Pillars of Creation (M 16, Messier 16) The dust and gas in the pi...

25 June 1975 BLACK DAY FOR INDIA (EMERGENCY)

25 June which is considered as black day for india. It was 25 June 1975 when Prime Minister Shri Indri Gandhi declared Emergency through radio in India. In India, "the Emergency" refers to a 21-month period from 1975 to 1977, Officially issued by President Fakhruddin Ali Ahmed under Article 352 of the Constitution, the Emergency was in effect from 25 June 1975 until its withdrawal on 21 March 1977. The order bestowed upon the Prime Minister the authority to rule by decree, allowing elections to be suspended and civil liberties to be curbed. For much of the Emergency, most of Gandhi's political opponents were imprisoned and the press was censored. Several other human rights violations were reported from the time, including a forced mass-sterilization campaign spearheaded by Sanjay Gandhi, the Prime Minister's son. RESION BEHIND EMERGENCY On 12 June 1975, Justice Jagmohanlal Sinha of the Allahabad High Court found the prime minister guilty on the charge of...

Spiral Galaxy Images taken by Hubble Telescope

This is the Andromeda galaxy — otherwise known as M31. This is the neighbouring galaxy of Milky way galaxy (our own galaxy). This is nearly 2 million light years away from earth. This is a NGC 7640 i. e. barred spiral type galaxy. These are recognisable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s centre. This is the part of Andromeda constellation. This is the image of the beautiful barred spiral galaxy NGC 1300. NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. This 60 million light years away from the earth and belong to the Eridanus Constellation. This is spiral galaxy Messier 77 — a galaxy in the constellation of Cetus, some 45 million light-y...
