Massive Black Hole Shreds Passing Star
What would the outcome be if you took a leap of faith straight into a black hole? We looked to Einstein and Hawking to ponder the scenario.
Say one day you were exploring space looking for a new planet for humans to inhabit, but came across a black hole and decided – why not check it out? Would you have any chance of survival? How would you get out if at all? Would you find a shortcut to another universe? Watch the video to learn about what would happen if you fell into a black hole.

Ice Planet - Breathtaking Footage Of Earth’s Wintry Side. 4K
About the Glacial periods of our Earth.
Over the past 3 billion years, the Earth has undergone approximately 5 significant ice ages.
The first one - Cenozoic Ice Age began 34 million years ago. The latest one - the Quaternary glaciation, which is in progress since 2.5 million years ago. Within the major ice ages there are the periods of severe and mild glacial conditions known as the glacial and inter-glacial periods. The Earth is currently in such an inter-glacial period of the Quaternary glaciation - the Holocene epoch.
The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago.
Interesting facts:
The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago.
Humans developed significantly during the most recent glaciation period, emerging as the dominant 'land animal' afterward as such large species as the mammoth, giant ground sloths, the mastodons, saber-toothed cats etc. which reigned during the glacial period went extinct by its end.
Humans were able to adapt to the harsh climate by developing such tools as the bone needle to sew warm clothing.
By the start of the mild Holocene epoch, our ancestors were in position to take advantage of the warm conditions by developing domestication techniques and agricultural.
An Ice age causes changes to the Earth’s landscape. Glaciers reshaping the surface by displacing soil and rocks, by eroding hills during their unstoppable movement.
Humans have recorded about 5 large-scale ice ages throughout the Earth’s history:
The Huronian (approx. 2.4 billion years ago),
The Cryogenian (approx. 850 - 635 million years ago),
The Andean-Saharan (approx. 460 - 430 million years ago),
The Karoo (approx. 360 -260 million years ago),
The Quaternary (approx. 2.6 million years ago - present).
Roughly a dozen major Glaciations have occurred over the past 1 million years.
The largest Glaciation peaked approx. 650, 000 years ago and lasted for 50, 000 years.
The most recent Glaciation period, known as the 'Ice Age', reached its peak conditions some 18,000 years ago, before passing the baton to the Interglacial Holocene epoch 11,700 years ago.

New: Mars In 4K
A world first. New footage from Mars rendered in stunning 4K resolution. We also talk about the cameras on board the Martian rovers and how we made the video.
The cameras on board the rovers were the height of technology when the respective missions launched.
A question often asked is:
‘Why don’t we actually have live video from Mars?’
Although the cameras are high quality, the rate at which the rovers can send data back to earth is the biggest challenge. Curiosity can only send data directly back to earth at 32 kilo-bits per second.
Instead, when the rover can connect to the Mars Reconnaissance Orbiter, we get more favourable speeds of 2 Megabytes per second.
However, this link is only available for about 8 minutes each Sol, or Martian day.
As you would expect, sending HD video at these speeds would take a long long time. As nothing really moves on Mars, it makes more sense to take and send back images.

Symphony Of Our Star - Real Images Of Sun - 4K
There are trillions of stars in the universe. Our own Star - the Sun is rather ordinary one.
The official classification for our Sun is a G-type main-sequence star (spectral type: G-V star).
The surface temperature of such stars is between 5027°C and 5727°C.
Interesting facts about Sun:
Our Star is a Yellow Dwarf star.
The Sun is composed of hydrogen (70%) and Helium (28%).
The Sun is halfway through its life - 4.5 billion years old.
It takes eight minutes for light reach Earth from the Sun.
Over one million Earth’s could fit inside the Sun.
The Sun has a very strong magnetic field.
The Sun is traveling at 220 km per second.
Our Star accounts for 99.86% of the mass in the Solar System.
The Sun’s surface area is 11,990 times that of the Earth’s.
The energy created by the Sun’s core is nuclear fusion.
One day the Sun will consume the Earth.
The Sun is almost a perfect sphere.
The Sun will eventually be about the size of Earth.
The distance between Earth and Sun changes.
The Sun rotates in the opposite direction to Earth.
The distance between the Earth and the Sun is an Astronomical Unit (AU)
Temperatures inside the Sun can reach 15 million degrees Celsius.
It takes the Sun 225 - 250 million years to complete an orbit of the centre of the Milky Way.
The Sun generates solar winds which travel through the solar system at 450 km per second.
The Auroras or Northern Lights, caused by the interaction of solar winds with Earth’s atmosphere.
Our Star is responsible for the Earth’s climate and weather.
Earth, along with the planets of our Solar System is a satellites of the Sun.
Sun have another common name - Sol, which originates from the ancient Roman’s god of the Sun - Sol.
The term 'solar system', literally means - System of the Sun

Moon - Close Up View - Real Sound. HD
Our Universe is not silent..
Although space is a vacuum, that does not mean there is no sound in it.
Yes, space is a vacuum - so it generally doesn't carry sound waves like air does here on Earth. However, some sounds do exist in outer space, we just can't hear them. Various probes that zoom through the space are capable of capturing radio emissions from astronomical objects. NASA's scientist have designed special instrument known as 'astronomical interferometer' which can record these electromagnetic vibrations, and transfer them into sounds within range of human hearing (20-20,000 Hz).
Interesting Facts about our Moon:
The Moon's Latin name is Luna.
The Moon formed approx. 4.5 billion years ago.
Moon is the fifth-largest natural satellite in the Solar System.
The moon orbits the Earth at an average speed of 3,700 kilometers an hour.
The Moon is in synchronous rotation with Earth - it is always shows Earth the same side.
The Moon’s surface is dark.
The dark side of the Moon cools to about -169 degrees Celsius.
During the lunar day that lasts about a month Moon's surface bakes in the sun at up to 117 degrees Celsius.
The Moon is drifting away from the Earth approx. 3.8 cm every year.
The Moon has quakes called the Moonquakes.
There is water on the Moon.
The Soviet Union’s Luna program featured the first successful landing of an unmanned spacecraft on the surface of the Moon in 1966.
The USA’s NASA Apollo 11 mission in 1969 was the first manned Moon landing.
