#Plutoflyby trends on Twitter as NASA's New Horizon sends breathtaking photo

In what can be called a historic moment for space exploration, an unmanned NASA spacecraft hurtled towards an area of space which has never been explored before and which scientists have nicknamed the 'Wild West' of space. The $700 million piano-sized Nasa spacecraft New Horizons made its closest approach to Pluto.[caption id="attachment_2342284" align="alignleft" width="380"] This photo from NASA shows New Horizons' look at Pluto's Charon-facing hemisphere.

But official confirmation will not come until Tuesday night, 13 nerve-racking hours later. That's because Nasa wants New Horizons taking pictures of Pluto, its jumbo moon Charon and its four little moons during this critical time, not communicating with Earth.However, Nasa has already put out one of the photos sent from New Horizon.

This photo sent Twitter users into a tizzy.And as the world waits with bated breath for more photos, the hashtag #plutoflyby started trending on Twitter with people hailing Nasa's ambitious project.Here's what people had to say on Twitter:
