Many mysteries are being associated with Pluto. Now, the New Horizons spacecraft is approaching the dwarf planet and showing many complicated features of it.

New Horizons captured a 360-degree view of the dwarf planet's surface and will now head for its planned flyby of the orbiting solar system outlier.

According to mission principal investigator Alan Stern of the Southwest Research Institute, "The images show an increasingly complex surface with clear evidence of discrete equatorial bright and dark regions . We can also see that every face of Pluto is different and that Pluto's northern hemisphere displays substantial dark terrains".

But it appears that both the brightest and the darkest regions of the dwarf planet are collected around its equator and so far this thing has not been explained by scientists.

Images that were captured by the Hubble Space Telescope and earlier New Horizons had already shown light and dark spots, however the latest images show that surface of the dwarf planet is more complex compared to what was thought earlier.

According to researchers, spectroscopic data may help provide more information regarding Pluto's many faces before the closest approach of the spacecraft on July 14.

New Horizons has travelled nearly 2.9 billion miles from Earth; the journey has already completed almost 10 years. According to NASA, the spacecraft is just a little over 20 million miles from Pluto, travelling at more than 36,000 mph.

Pluto was considered as a member of the solar system's planetary family, when the spacecraft was launched in 2006.
