Our Solar System In Focus

Robotic probes launched by National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and others are gathering information right now all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn. Several others on their way to smaller bodies, and a few on their way out of the solar system entirely. 

 On Mars, a rover called Spirit has just been officially left for dead, after two years of radio silence from it but its twin, Opportunity, continues on its mission, now more than 2,500 days beyond its originally planned 90-days. 

 With all these eyes in the sky, here is a photo album of our Solar system, a set of family portraits, as seen by our astronauts and mechanical emissaries.

When a rather large-sized (M 3.6 class) flare occurred near the edge of the Sun, it blew out a gorgeous, waving mass of erupting plasma that swirled and twisted over a 90-minute period on February 24, 2011. This event was captured in extreme ultraviolet light by NASA's Solar Dynamics Observatory spacecraft . Some of the material blew out into space and other portions fell back to the surface.

9 Tallest Mountains In Solar System

Mount Everest, at 29,029 feet tall (5.5 miles), is the tallest mountain on earth. But, not known to many, Hawaii's Mauna Kea is actually much more taller than Everest, which is actually 33,465 feet tall, although only 13,796 of which are above sea level. 

If we look beyond our planet earth, there are lots and lots of taller mountains compare to Everest and Mauna Kea. Following are the tallest mountains in various worlds of the Solar System. Heights are given base to peak.

9. Arsia Mons, Mars > 9 km (5,6 mi)

Arsia Mons is 270 miles (approximately 435 kilometres) in diameter, almost 12 miles high (more than 9 kilometers (5.6 mi) higher than the surrounding plains), and the summit caldera is 72 miles (approximately 110 km) wide. It experiences atmospheric pressure lower than 107 pascals at the summit. Except for Olympus Mons, it is the biggest volcano in volume. Arsia Mons has 30 times the volume of Mauna Loa in Hawaii, the largest volcano on the Earth.


8. Mauna Kea, Earth = 10,2 km (6,3 mi)

Mauna Kea (Hawaii) has an altitude of 4,205 meters (2,6 mi) - much lower than Mount Everest. However, Mauna Kea is an island and if the distance from the bottom of the nearby ocean floor to the peak of the island is measured, then Mauna Kea is taller than Mount Everest.  Mauna Kea is over 10 km (6,2 mi) tall compared to 8.848 m (5,5 mi) for Mount Everest - making it the Earth's tallest mountain.
