NASA’S Voyager 1 spacecraft has reached the outer edge of the solar system where wind from the Sun is no longer blowing outward, but sideways, the US space agency said.
The spacecraft was launched in 1977 and has since snapped images of Earth and other planets in the solar system and provided NASA with crucial information as it makes its long journey into outer space.
NASA researchers think Voyager 1 will leave the solar system and enter interstellar space, or the area in between the end of the Sun’s influence and the next star system, in about four years.
For now, Voyager 1 is 17.4 billion kilometres from the Sun in “an area where the velocity of the hot ionised gas, or plasma, emanating directly outward from the Sun has slowed to zero”, the space agency said.
“Scientists suspect the solar wind has been turned sideways by the pressure from the interstellar wind in the region between stars.”

What Are the Advantages of Moving From Traditional Phones to Voip?
VoIP phone services utilize Internet cables, as opposed to analog wires.
VoIP, or voice over Internet protocol, represents the latest in telephone communications technology. According to NASA, a VoIP system uses a broadband Internet connection to transfer digitalized data between parties, as opposed to using a standard analog telephone line. Making the switch to a VoIP system can have several advantages, both at home and in the office.
Sound Quality
As the technology and communications resource TechEn Enterprises notes, the earliest VoIP systems, which came out in 1998, were often plagued with voice-quality issues. However, today’s VoIP systems offer sound quality that at least equals, and often surpasses, the sound quality of standard phone systems.
Less Wiring
With a VoIP system, your home’s or company’s phones can transmit and receive data using the same Internet cables you already have in place. This means no more messy bundles of wiring and lower installation costs in comparison to traditional phone systems, which require independent wiring.
Ease-of-Use
According to the Federal Trade Commission (FTC), the majority of VoIP systems—through the use of adapters—allow you to continue to use the traditional telephone handsets you are used to. This means there is no learning curve if you decide to make the switch from traditional to VoIP: Simply dial as usual.
