Samsung has suspended the sale of Galaxy 7 smartphone as it catches fire when it is in charge. 35 cases were reported that the newly launched device exploded while being charged. Samsung has asked their customers to return the device and replace it with other model Samsung phones.

Koh-Dong-Jin President of Samsung mobile business said that they had received reports of battery explosions two weeks after the launch of Galaxy 7 smartphone. He reported it has a battery cell problem and it was very difficult to find it out. He refused to reveal the name of the battery supplier.

He also said that the note7 model sold in China used batteries made up by a different provider and there were no defects in those devices. Samsung is in the process of conducting an inspection on their batteries supplied by different suppliers. The company is working hard to sort out what went wrong. But Samsung gives more importance to the safety of their customers, so they have stopped the sale of Galaxy Note7.

Samsung has assured a replacement in the coming week for their customers who own a Galaxy Note7. Samsung tries to rectify their fault by launch delay and product swap.

NASA shared the great news of discovering nearly 1200 planets in the galaxy. This was possible by using Kepler’s space telescope. NASA found this on their journey towards finding Earth-like planets. Nasa’s Chief Scientist Ellen Stofan said that it is possible to discover a planet similar to earth in the years to come.

Kepler, the space telescope detected 4,302 possible planets of which Nasa decided on 1284 candidates who have a 90% chance of being a planet. Kepler confines its search to the habitable zone and does not move further. Mission scientist Natalie Batalha told reporters that the Kepler telescope had identified 36 new planets in the Goldilocks Zone. It also found that out of the 1200 planets discovered 550 are confirmed rocky planets like the Earth. There are totally 21 exoplanets of the same size of the earth. It also orbits as the same as the earth.

Kepler detects new candidates by noticing the tiny dimming of light when a planet passes in front of its star. But these signals can also be caused by any moving particles in the space which create false positives. Thus it is essential to be cautious to avoid false positives.

The data from Kepler along with the new statistical technique published in the Astrophysical Journal has helped the astronomers to confirm the planets. Three transits are used to confirm detection. NASA reports that their scientists are working for 15 years to confirm about 2000 transient planets.

Kepler was launched in the year 2009, and it has identified 5,000 candidates of which 2,325 candidates were verified as planets.

Future missions of NASA will add additional inputs to Nasa’s Data. NASA has scheduled to launch several new telescopes in the coming decade. TESS is a telescope which is yet to be launched. Scientists say that Tess can examine the stars closer than the Kepler.
Kepler has fuel to perform for more than two years said Charlie Sobeck, Kepler’s mission manager.
