There is a limit to how deep we can go underwater. Certain pressure level would crush us and i think (someone correct me if i'm wrong) the same applies to technology to some degree.

ScienceDaily (Mar. 26, 2012) — Filmmaker and National Geographic Explorer-in-Residence James Cameron descended 35,756 feet (6.77 miles/10.89 km) to reach the "Challenger Deep," the ocean's deepest point located in the Mariana Trench, in his specially designed submersible DEEPSEA CHALLENGER. The attempt was part of DEEPSEA CHALLENGE, a joint scientific expedition by Cameron, National Geographic and Rolex to conduct deep-ocean research and exploration. Cameron is the only individual ever to complete the dive in a solo vehicle and the first person since 1960 to reach the very bottom of the world in a manned submersible. During the dive, he conducted the first manned scientific exploration of the "Challenger Deep."

The submersible was launched into the Pacific Ocean some 200 miles (322 km) southwest of Guam on Monday, March 26, at 5:15 a.m., local Guam time (Sunday, March 25, at 3:15 p.m., Eastern Time). The voyage down to the "Challenger Deep" took two hours and 36 minutes. Cameron resurfaced at 12 noon local Guam time on Monday, March 26 (10 p.m. Eastern Time on Sunday, March 25). The submersible -- the result of a more-than-seven-year engineering effort -- stayed on the bottom for about three hours as Cameron collected samples for research in marine biology, microbiology, astrobiology, marine geology and geophysics. Cameron also captured still photographs and moving images to visually document the Mariana Trench.

"This journey is the culmination of more than seven years of planning for me and the amazing DEEPSEA CHALLENGE expedition team," said Cameron. "Most importantly, though, is the significance of pushing the boundaries of where humans can go, what they can see and how they can interpret it. Without the support of National Geographic and Rolex, and their unwavering belief that we could successfully make it to the deepest point in the ocean -- and back -- this would not have happened."

"We join the rest of the world in celebrating the exhilarating achievement of Jim Cameron and the DEEPSEA CHALLENGE expedition team," said Terry Garcia, National Geographic's executive vice president of Mission Programs. "In 2012 we are still exploring largely unknown places -- as National Geographic has been doing for nearly 125 years. I'm delighted to say that the golden age of exploration and discovery continues."

Details on the expedition can be found at www.DEEPSEACHALLENGE.com; on Twitter by following @DeepChallenge or using #deepseachallenge; or on Facebook at https://www.facebook.com/deepseachallenge.

The "Challenger Deep" has only been reached once before in a manned descent, on Jan. 23, 1960, by then U.S. Navy Lt. Don Walsh -- who is a consultant on the DEEPSEA CHALLENGE expedition and was aboard the expedition ship Mermaid Sapphire during Cameron's successful attempt -- and Swiss oceanographer Jacques Piccard in the bathyscaphe Trieste. Walsh and Piccard spent about 20 minutes on the ocean floor before returning to the surface.

With breakthroughs in materials and science, unique approaches to structural engineering and new ways of imaging through an ultra-small, full ocean depth-rated stereoscopic camera, Cameron was able to launch the DEEPSEA CHALLENGE expedition, which he hopes will shed light on other virtually unknown deep-water habitats, such as the New Britain Trench and the Sirena Deep.

Cameron's CAMERON | PACE Group, which supplies 3-D technologies /and production support services, provided the capability to document today's historic dive in high-resolution 3-D.

Europa’s “chaos terrain”
By Britney Schmidt/Dead Pixel FX/Univ. of Texas at Austin
Published: Nov. 16, 2011

In a significant finding in the search for life beyond Earth, scientists from The University of Texas at Austin and elsewhere have discovered what appears to be a body of liquid water the volume of the North American Great Lakes locked inside the icy shell of Jupiter’s moon Europa.

The water could represent a potential habitat for life, and many more such lakes might exist throughout the shallow regions of Europa’s shell, lead author Britney Schmidt, a postdoctoral fellow at the university’s Institute for Geophysics, writes in the journal Nature.

In this video animation of a cutaway view of Europa’s icy shell, we see how vast lakes form below the surface.

Further increasing the potential for life, the newly discovered lake is covered by floating ice shelves that seem to be collapsing, providing a mechanism for transferring nutrients and energy between the surface and a vast ocean already inferred to exist below the thick ice shell.

“This new understanding of processes on Europa would not have been possible without the foundation of the last 20 years of observations over Earth’s ice sheets and floating ice shelves,” said Don Blankenship, a co-author and senior research scientist at the Institute for Geophysics, where he leads airborne radar studies of Earth’s ice sheets

Titan
http://en.wikipedia.org/wiki/Titan_(moon)

The atmosphere of Titan is largely composed of nitrogen; minor components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog. The climate—including wind and rain—creates surface features similar to those of Earth, such as sand dunes, rivers, lakes and seas (probably of liquid methane and ethane), and deltas, and is dominated by seasonal weather patterns as on Earth. With its liquids (both surface and subsurface) and robust nitrogen atmosphere, Titan's methane cycle is viewed as an analog to Earth's water cycle, although at a much lower temperature.

The satellite is thought as a possible host for microbial extraterrestrial life or, at least, as a prebiotic environment rich in complex organic chemistry with a possible subsurface liquid ocean serving as a biotic environment

All relatively at our door step.






Something like this though,

Crab Pulsar (6520 light-years)

A neutron star , 25 km in diameter, same mass yet 410000000000000 times the density of our Sun, 38328472000000000 miles away.

This stuff is like food for my brain man. It's getting to the point that this is stuff I look for everyday. It also saddens me that more resources aren't put into space and space exploration.

Always been a big fan of Mercury..

Density of Mercury
The density of Mercury is the second highest in the Solar System. Earth is the only planet that is more dense. It is 5.427 g/cm3 compared to Earth’s 5.515 g/cm3. If gravitational compression were to be removed from the equation, Mercury would be more dense. The high density of the planet is attributed to its large percentage of core. The core constitutes 42% of Mercury’s overall volume.

Mercury is a terrestrial planet like Earth, one of only four in our Solar System. Mercury is about 70% metallic material and 30% silicates. Add the density of Mercury and scientists can infer details of its internal structure. While the Earth’s high density mainly results from gravitational compression at the core, Mercury is much smaller and is not so tightly compressed internally. These facts have allowed NASA scientists and others to surmise that its core must be large and contain overwhelming amounts of iron. Planetary geologists estimate that the planet’s molten core accounts for about 42% of its volume. On Earth that percentage is 17.



Interior of Mercury

That leaves a silicate mantle that is only 500–700 km thick. Data from Mariner 10 led scientists to believe that the crust is even thinner, at a mere 100–300 km. This surrounds a core that has a higher iron content than any other planet in the Solar System. So, what caused this disproportionate amount of core material? Most scientists accept the theory that Mercury had a metal-silicate ratio similar to common chondrite meteorites several billion years ago. They also believe that it had a mass of about 2.25 times its current; however, Mercury may have been impacted by a planetesimal 1/6 that mass and hundreds of km in diameter. The impact would have stripped away much of the original crust and mantle, leaving the core as a major percentage of the planet.

While scientists have a few facts about the density of Mercury, there is still more to be discovered. Mariner 10 send back a great deal information, but was only able to study about 44% of the planet’s surface. The MESSENGER mission is filling in some of the blanks as you are reading this article and the BepiColumbo mission will go even farther in extending our knowledge of the planet. Soon, there mat be more than theories to explain the high density of the planet.

Density of Mercury in grams per cubic centimeter: 5.427 g/cm3

I look at the brain like a muscle. If you want it to grow big and strong you have to constantly feed it information and exercise your knowledge. In my case, I want it to be over saturated with information.

@Pabst16oz are you a scientist, a degree in astrophysics or just interested in astronomy?
