How deep are some of the best known sunken ships? Some of them are shown in this 3D animation, including some submarines and airplanes.

This is not a submarine, but the Titan, is a, Cyclops-class manned submersible. But,what's the difference between the two ? The primary difference between a submersible, and a submarine, is that the submersible is launched from a mother vessel or home vessel. They are typically launched on a raft or platform, which is placed into the ocean! and ultimately descends via four electric thrusters, which helps it to reach speeds of around 3 knots. But a Submarine can dive underwater, without any external equipment, and surface all through the process of buoyancy.

The sinking of the RMS Titanic occurred between the night of April 14 and the morning of April 15, 1912, in the North Atlantic, four days after the beginning of its maiden voyage, which began in Southampton, England, bound for New York City. York, in the United States. The Titanic was the largest passenger ship in service at the time, it had 2208 people on board when it hit an iceberg at around 11:40 pm (ship time)[a] on Sunday, April 14, 1912. The sinking took place two hours and forty minutes later at 02:20 (05:18 GMT) on Monday, April 15, resulting in the deaths of 1,496 people, making it one of the worst disasters in the history of shipping. Titanic received six sea ice warnings on April 14, but was close to top speed when her lookouts spotted the iceberg. Officer William Murdoch ordered the rudder to turn all the way to starboard in an attempt to avoid the iceberg, but without success, as the ship collided with the iceberg, probably damaging six or seven watertight compartments. The Titanic was designed to float with four of her forward watertight compartments flooded, no more, and Thomas Andrews, the chief designer, soon realized that the ship was going to sink. The crew used flares and radiotelegraphy messages to seek help, while passengers were loaded into lifeboats. In keeping with existing practice, the Titanic's lifeboat system was designed to transport passengers to nearby rescue vessels, not to have everyone aboard one lifeboat simultaneously; so with the ship sinking fast and help still a long way off, there was no safe haven for many of the passengers and crew. With that and poor evacuation management, many boats were launched before they were completely full. So when the Titanic sank, over a thousand passengers and crew were still on board. Nearly everyone who jumped or fell into the water sank or died within minutes from the effects of hypothermia. The British passenger ship Carpathia recorded the Titanic's distress calls as it sailed some 93 km away. It deviated from its course and arrived at the site around an hour and a half after the sinking, rescuing the last survivors around 9:15 am on April 15, almost nine and a half hours after the collision. The disaster caused widespread outrage over the lack of lifeboats, lax regulations, and the unequal treatment of the three classes of passengers during the evacuation. Subsequent inquiries recommended sweeping changes to maritime regulations, leading to the establishment in 1914 of the International Convention for the Safety of Life at Sea (SOLAS), which still regulates maritime safety today.

During our 2022 expedition to the world's most iconic shipwreck, we were able to capture the very first 8K video of the Titanic.

Venus, the third brightest object in our sky, this planet has always attracted skywatchers and scientists. For many years, dense and impenetrable clouds enveloping its surface excited the imagination of observers, which gave rise to ideas of now a boundless ocean, then impassable jungles teeming with monsters. The reality turned out to be even more complicated and horrifying than these naive assumptions. So what is Venus really hiding from us?

This all started way back in 1964, the Soviet scientist, Nikola Kardashev, developed a classification system that groups civilizations based on their technological progress and energy consumption. This scale, known as the Kardashev Scale, ranges from Type 1, which represents a civilization that has not yet harnessed the full potential of its own planet, to Type 3, which can harness the energy of an entire galaxy. The interplay between energy and technology is a fundamental principle that underlies the progress of civilizations. As society gains access to more energy sources, it can develop new technologies that enable it to harness even more energy, leading to a self-reinforcing cycle of advancement.

Imagine the world without water: as cold and lifeless as the planet Mars. Earth is unique in our solar system in being able to sustain liquid water on its surface. Water is essential for life and for Earth’s climate, helping transport heat around the planet, but it is difficult to track through the whole water cycle. The global view offered by satellites helps. ESA’s Climate Change Initiative is looking at a range of climate variables linked to the water cycle.

This visualization shows the unusual motions of Earth and the Sun as viewed from the South Pole of the Moon. The animation compresses three months (a little over three lunar days) into two minutes. The virtual camera is on the rim of Shackleton Crater, partially visible in the bottom right, and is aimed at the Earth. The mountain on the horizon, about 85 miles away, is unofficially known as Mons Malapert. Here, the Sun glides around the horizon, never more than 1.5 degrees above or below it, while the Earth bobs up and down, never veering far from 0° longitude. The Earth appears to be upside-down and rotating backwards. The perpetually low Sun angle produces extremely long shadows that rotate across the rugged lunar terrain. In the second month of the visualization, Earth passes in front of the Sun, creating an eclipse. For observers on Earth, this is a lunar eclipse, in which the Moon passes through the shadow cast by Earth. Viewed from the Moon, however, this is an eclipse of the Sun.

At NASA, our mission is to explore. We visit destinations in our solar system and study worlds beyond to better understand big questions. How did we get here? Where are we headed? Are we alone? While our robotic explorers have toured our solar system, the only place beyond Earth where humans have stood is the Moon. That’s also the next place we’ll send astronauts. But not the last! While humans haven’t yet visited Mars, we’re planning to add boot prints to the rover tire tracks there now. We also dream of traveling to distant worlds, and what they might be like. This video shows fanciful, imagined adventures to real places we’ve studied.

The working of rocket and rocket engine are elaborated in a detailed way with help of animation here. The topics covered are liquid propellant rockets, solid propellant rockets, rocket nozzle, rocket staging, rocket guidance & gimbaled thrust,.

Drone footage filmed between 2013 and 2016 shows the Ukrainian city of Pripyat and the Chernobyl nuclear facility. In 1986, the population of 50,000 people were evacuated after the reactor at the nuclear plant exploded.

What did the Titanic look like from the inside? I'll take you on a virtual tour of the Titanic - before the accident, of course. Together, let's see how luxurious this vessel was! First off, of course, just look at her size. The Titanic was one of the largest ocean liners of its time, rivaled only by its sister ships, Olympic and Britannic. Even by today's standards, the vessel is quite impressive. For example, the Titanic's pride and glory was the grand staircase. The view immediately took everyone by surprise, and that's no surprise: the ladder was the Titanic's pride and glory. This magnificent thing was made of oak and wrought iron, decorated with intricate patterns, all handmade. Its central part was simply fascinating: a masterful wooden carving with a clock. And above, there was a beautiful glass dome designed to create an illusion of daylight. Let's find out what the interior design of the Titanic was like and what was the difference between 1st, 2nd and 3rd class on the Titanic!
