Imagine making plans with your friends — by walking to their house to talk in person.
That’s the norm at Green Bank, West Virginia, where its 143 residents can’t rely on their cellphones or tablets to connect with friends and loved ones because all wireless devices are forbidden.
Located within a 13,000-square mile area known as the National Radio Quiet Zone, Green Bank houses the National Radio Astronomy Observatory, which operates the world’s largest radio telescope.
“It’s the study of the natural radio emissions that are coming from bodies in space,” explained Michael Holstine, the observatory’s business manager.
Standing 485-feet tall and weighing nearly 17-million pounds, the telescope is so large that a college football stadium could fit inside the dish. It’s also incredibly sensitive to electronic interference and, Holstine said, so powerful that it could pick up “the energy given off by a single snowflake hitting the ground.”

An enormous celestial gas cloud that first left the Milky Way when dinosaurs roamed the Earth is speeding back towards the galaxy at roughly 700,000 miles per hour, a study in The Astrophysical Journal Letter Reports.
The cloud – known as “The Smith Cloud” – was first ejected from the Galaxy some 70 million years ago. It is full of sulfur, over 11,000 light years long, nearly 2,500 light years wide, and has the mass of roughly one million suns. It is shaped like a comet and contains no stars, making it invisible in optical wavelengths.

Though hundreds of enormous high-velocity gas clouds whiz around the outskirts of our galaxy, this so-called “Smith Cloud” is unique because its trajectory is well known.
Hubble Space Telescope astronomers are finding that the old adage, “What goes up, must come down” even applies to an immense cloud of hydrogen gas outside our Milky Way Galaxy. The invisible cloud is plummeting toward our galaxy at nearly 700,000 miles (1,100,000 kilometers) per hour.
Though hundreds of enormous high-velocity gas clouds whiz around the outskirts of our galaxy, this so-called “Smith Cloud” is unique because its trajectory is well known. New Hubble observations suggest it was launched from the outer regions of the galactic disk around 70 million years ago. The cloud was discovered in the early 1960s by Gail Smith, who detected the radio waves emitted by its hydrogen.
The cloud is on a return collision course and is expected to plow into the Milky Way’s disk in about 30 million years. When it does, astronomers believe it will ignite a spectacular burst of star formation, perhaps providing enough gas to make 2 million Suns.

Since astronomers discovered the Smith Cloud, a giant gas cloud plummeting toward the Milky Way, they have been unable to determine its composition, which would hold clues as to its origin. Astronomers have now determined that the cloud contains elements similar to our sun, which means the cloud originated in the Milky Way’s outer edges and not in intergalactic space as some have speculated.

Green Bank, in Pocahontas County in West Virginia, USA, is one of the quiet residential place on earth. Here there is absolutely no cell phone signal, no Wi-Fi signal, even here there is no radio and television waves that can be captured.
But Green Bank instead of lagging behind in technology. Instead, this area is home to one of the world’s largest radio telescope named Robert C. Byrd Green Bank Telescope (GBT), operated by the National Radio Astronomy Observatory. GBT is the reason why this town electromagnetic silence from the crowd.
Radio telescope works by detecting the electromagnetic waves coming from distant galaxies. This signal is so faint that small emission of radio waves from electronic gadgets may interfere with the reading of the radio telescope. For this reason, all mobile phones, Wi-Fi, radio and other communication devices are prohibited here. There is no cell phone towers around this area, there is no music played on the radio or on television soap operas. Even gasoline-fueled cars are not allowed because gasoline engines use a spark to burn a mixture of fuel and air, and electrical sparks generate electromagnetic waves.
