Voyager 2 Has Entered The Interstellar Space

The Voyager 2 probe was propelled in 1977 to study the four monster planets of the Solar System. More than 40 years after the fact, and having voyage relatively 17.7 billion kilometers (marginally under 11 billion miles), the spacecraft may close to one of the boundaries of the Solar System, the end of the heliosphere.

It could before long be joining its twin, Voyager 1, and become into the second human - made object to enter interstellar space.

The heliosphere is the district of space dominated by the solar wind and attractive fields. Past it, the hydrogen and helium gas that pervades our galaxy become prevailing. Past the heliosphere, cosmic beams become more common as they are deviated less and less by material from the Sun, and Voyager 2 has recorded an expansion of approximately 5 percent since early August, implying at its goal.

This is fundamentally the same as what Voyager 1 saw in May 2012, only three months previously it crossed the heliopause, the external edge of the heliosphere. And for this reason, analysts believe that Voyager 2 is going to take the momentous act of crossing that boundary limits. 

"We are seeing a change in the atmosphere around Voyager 2, there is no uncertainty about that," said Ed Stone, Voyager venture researcher based at Caltech in Pasadena, in an announcement.

"We are going to study a lot in the coming months, however despite everything we don't know when we will achieve the heliopause. We are not there yet – that is one thing I can say with certainty."

Voyager 2 is one of the numerous observatories far from Earth that review the changes of our Sun and how they influence our planet, different planets, and the Solar System in general. Voyager 2 is giving analysts the uttermost point of view on this interesting region of science.

The heliosphere is regularly alluded to as a bubble yet it isn't actually a sphere and it changes. It depends emphatically on the movement from the Sun, and as our star experiences its 11-year cycle, it grows and contracts. Voyager 1 has effectively gone into interstellar space since it moves significantly quicker and is considerably farther – it's the furthest human-made object from Earth – yet additionally the changes in the heliosphere size may be pertinent. It will be interesting to see how extraordinary the experience of Voyager 2 is from Voyager 1.
