Petya Cyber Attack

A massive cyber-attack in the form of ransomware has gripped Ukraine. Britain, Danish and Spanish firms were also crippled in the virus attack. All the firms, airports and government departments were affected, and later, the attack spread all over Europe. Metro networks, central banks, and state aircraft manufacturers were also paralyzed. A shipping firm in the Netherlands and advertising firm in the UK declared that their systems were too malfunctioning due to the attack. The virus came in the form of ransomware. This happened a week after the WannaCry hack that affected almost 150 countries.

The attack on 27th June 2017 was dealt on high priority as it questioned the safety of the nations affected. Maersk, a famous logistics company, shut down many of its operations after the attack. Rosneft, the most famous Russian oil company, suffered a setback too with severe damage to its servers.

Let us have a glance through the events that were unfolded immediately after the terrible attack:
3:06 pm- The British advertising firm, WPP confirmed that it was a victim of the attack.
3:08 pm- Rosneft, the Russian oil mascot said that it suffered terrible loss after the hack.
There was a tweet from the deputy prime minister of Ukraine confirming the virus attack.
3:11 pm- Maersk’s 17 container terminals were down because of the attack.
3:23 pm- Experts look at the consequences of the attack and ascertain that Petya ransomware is behind the attack.
3:27 pm- Several Spanish forms were also under attack.

Discovery Of Exoplanets

NASA has discovered seven Earth-sized planets near a star. They are the hope that they could sustain life. Google represented the planets with a doodle too in the happy mood. TRAPPIST-1 is the transiting planets and planetesimals small telescope. A star was discovered in the Aquarius constellation 40 light years away from the Earth. All the seven planets circle the TRAPPIST-1 in orbits from one and a half to twenty days. Six Exoplanets have a temperature range of 0-100 degrees Celsius. Three of these planets are known to have water in the form of oceans. These planets are rocky and are sized same like Venus or Earth. All these planets are warm as the parent star is dim.

These TRAPPIST-1 planets are very close to each other and fit in the Mercury’s orbit to be precise. The heart star of this system is 200 times dimmer than the sun. The glow is red or salmon-colored.
Three exoplanets are in the habitable zone known as the Goldilocks zone. Here, the stellar energy is in the right amount. These planets are under scrutiny as no other star has seven earth-sized planets with favorable conditions. Studies are going on though to know about the living conditions.

The discovery was made using the NASA’s exoplanet hunting Spitzer space telescope. It uses the infrared ray technology, and the data gave them the weights, densities, and masses of the planets. The telescope has the same orbit of the earth and is functional till 2018. Exo-planet means a planet outside our solar system. Almost 3500 exoplanets were discovered till now, but none of them gave the hope of sustaining life on them. All the hopes are pinned on these seven planets now. Coming to the matter of TRAPPIST-1, it is an ultra-cool dwarf star maybe a bit larger than the planet Jupiter. Further studies will be made by the Hubble’s and James’s telescopes.
