Uranus…
Seventh planet in the solar system in order of distance from the Sun, third in diameter, and fourth in mass.
Average distance from the Sun: 2.871 billion kilometers…
Orbital period: 84 years… How long would it take to go to Uranus?
Equatorial diameter: 51,100 km, exactly 4 times that of Earth
Mass of 14.6 times that of Earth…
Rotational period: 17.25 hours…
Minimum temperature: -226°C
27 satellites detected so far…
A hostile world…
Already flown over by one of our probes many years ago
A world full of mysteries…

And we are about to return to it…

Above us, hidden in darkness, the blue giants Uranus and Neptune are claiming our attention.
Much larger than Earth, than Mars, than Venus — yet so distant as to be invisible to the naked eye.
We encountered them only once, when Voyager 2 flew over them in 1986 and 1989, then passed on until they were lost in interstellar space.

Michio Kaku: We FINALLY Found What's Inside A Black Hole!



FOR COPYRIGHT ISSUES CONTACT:Mmarmelonic@gmail.com

Black Holes might just be one of the most fascinating and mysterious phenomena in the universe. They are massive beasts in terms of power, but at the same time, virtually invisible to us. But because of the research that was put into them over the last couple of decades, we’ve gone from knowing absolutely nothing about them, to getting to learn more and more, up close and personal. And well, things have just gotten crazier. Michio Kaku just announced that we’ve finally gotten a look at what’s inside a black hole, and this new information brings light to the details the world of science might’ve missed, all along. Join us as we dig deeper into black holes, and unveil what’s inside space’s “big bad.”

In the popular imagination, the alignment of the planets in the solar system is a mystical event that only happens occasionally. But is it possible for ALL the planets to align simultaneously? And if it were possible, what effects would this event have on Earth?
Let’s find out!
Is it physically possible for the planets to align?
The planets in our solar system never line up in one perfectly straight line, as they show in the movies. If you look at a two-dimensional plot of the planets and their orbits on paper, you may be led to believe that all the planets will circle to the same line. But, the planets do not all orbit perfectly in the same plane. Instead, they swing about on different orbits in three-dimensional space. For this reason, it is unlikely that they will ever align.
In the solar system, each planet orbits the Sun in its orbit, which has a unique inclination concerning the plane of the ecliptic (the ecliptic is the plane in which the Earth orbits the Sun).

Elon Musk's Future City

Elon Musk's Future City

– –
According to Forbes Elon Musk, the CEO and founder of Tesla and SpaceX is the most innovative person in the world for the consecutive second time this year. And that is very clear of the unbelievable success he has achieved in business. Ten years ago, people considered him a reckless man with extravagant ideas. In 2008, his company Tesla collapsed during the financial crisis. Now Tesla is one of the most successful niche car companies in producing electric cars, all due to the fact that Elon Musk persevered and was determined. He has done what was thought to be impossible 10 years ago. But he has no plans of stopping soon.
——————————————————————————————-
Elon Musk believes that day by day the technology is only getting better and better. Things are developing so fast that the future might be filled with Exponential tech advances that would change the world. In the future, we will have video games so realistic that it would be difficult for us to tell the difference between games and reality. From self driving tunnel networks to brain controlled computers, we’re going to look at how Elon Musk and his technology will take us forward and creating the city of the future. Elon says that we always want the future to be better than the past. A future that is exciting and one that the people would want to live in. A few decades ago a lot of technological advances seemed unimaginable but today they are our new normal, life without them is unimaginable. So let’s look at what would Elon Musk’s city of future look like.

So how will we get from one city to another in Elon’s future city? It’s hard to imagine being able to fly from New York City to Shanghai in 39 minutes or from Sydney to London in an hour. But this is something that Elon and SpaceX are working on. Elon compares Space Rockets to airplanes saying that if you do not reuse a plane, it would cost up to 250 million dollars to fly one way but because we can reuse them tens of thousand of times, it becomes affordable. The same is true for Space Rockets. A SpaceX rocket costs about 57 million dollars and if the rocket is reused a thousand times it nearly costs 57 thousand dollars per flight and by carrying people, we can get the price of a rocket flight down to the price of an economy flight ticket. The starship rocket is being developed to take people to mars, it can also transport people from city to city. In a 2017 interview Elon said that he is working for this to become a reality in the next 10 years and if you can carry people, you can also carry cargo which means a super fast delivery for people. Another way of getting packages fast from one part of the country to another will be by Electric semi trucks being developed by Tesla. These semi trucks require a driver but in the future we will see entirely driverless version of these and making deliveries and making the transportation cheaper. Also these trucks will be good for environment because 25% of greenhouse gases come from the trucking industry. Though these ideas seem far fetched and Elon has planned to make them possible in the next 10 to 12 years. There is yet another way that Elon plans to develop, and that is transportation via hyper loop. Elon Musk asks that when you think about a new transportation system, what would you want ideally? You will want something that would cost half the price to travel, would be twice as fast, cannot crash and immune to weather. To make this possible Elon is working on the idea of Hyperloop, which will take about 12 minutes to travel from Dubai to Abu Dhabi and will also be powered by solar panels. There will be Hyperloop stations inside cities, making it easier and faster to travel.

What Is The Lifetime Of A Photon?

What Is The Lifetime Of A Photon?

As you may have read somewhere, light only takes 8 minutes to cover the distance between the Sun and the Earth. Yes, that’s an insanely short time, considering that we are talking about 150 million kilometres! But the light that reach us is actually produced at the centre of the Sun, in its core, where nuclear reactions occur. So, have you ever asked yourself how long does light take to reach the surface of the Sun, starting from its centre?
Well, we may attempt to find a rough estimate. Consider that the Sun has a radius of “only” 696,000 kilometres (compared to the 150 million kilometres that separates it from the Earth)… so we would expect light to reach the surface in, let’s say, a few seconds, is it?
…you may be surprised to hear that this estimate is totally wrong! In fact, light takes… (drums)…. Thousands of years to reach the surface of the Sun!
Wait, what? How is that possible?
…curious to know how? Stick with us and we will tell you the answer in this video!

Before talking about the journey of light from the centre of the Sun to the Earth, we need to do a short digression about light. Stick with us, it won’t be that long.
What is light? Well, light is something fascinating: in fact, it has a “dual” nature. What does it mean? It means sometimes it behaves as a wave, and sometimes it behaves as a particle. Let me tell you more.
In the past centuries, scientists believed that light was a wave. And they were right, but.. that was only half of the story. At the end of the 19th century, and precisely in 1900, in order to explain some weird phenomena that were puzzling scientists, the German physicist Max Planck postulated that light was actually consisting of particles, called “photons”. Planck’s idea found confirmation five years later, in 1905, when Albert Einstein (this guy again!) managed to successfully explain the “photoelectric effect” by using Planck’s idea. The photoelectric effect is a well-known phenomenon that occurs when light is shone at a material (metals, in particular) and electrons are emitted from its surface as a result. By thinking light as a wave, some aspects of this phenomenon could not be explained. For instance, if the frequency of light was under a certain threshold, no electrons were emitted from the material, no matter how strong the intensity of the light beam is. However, by thinking light as a “bunch of particles”, the photons, this effect could then be explained. In fact, each photon in the light beam carries a certain amount of energy, and when the photon hits an electron in the material, it gives all its energy to the electron, which is now able to “escape” the material. The energy of the photon depends on the frequency of the light beam: so if this frequency is lower than a certain threshold, the photon has not enough energy to allow the electron to “escape” the material. The intensity of the light beam only determines the number of photons in the beam: so it doesn’t matter if we increase the intensity, we will only have more photons, but none of them will be able to “free” electrons from the material, because none of them has enough energy to do that. For realizing this, Einstein won the Nobel Prize.
Now that we have realized that light consists of photons, let’s go back to our original topic: why does light take so long to reach the surface of the Sun?
To answer this question, we have to start by looking at what happens in the core of the Sun. As in every other star, the core of the Sun is the “motor” that produces all the energy and the light emitted by our star.

Saturn's Moon Enceladus Could Have Signs Of Life

Saturn's Moon Enceladus Could Have Signs Of Life

From whether the moon known as Enceladus honestly has the potential for life, to what we would do if it honestly has it, and more! Join us as we explore how Saturn’s moon Enceladus could have Signs of life!

As such, as we look at the various planets and even the moons that surround them, we look for anything that could give us a hint that there is indeed life out there. Which brings us to Saturn and one of its many moons.
In 2005, NASA’s Cassini Saturn orbiter discovered geysers blasting particles of water ice into space from “tiger stripe” fractures near Enceladus’ south pole. That material, which forms a plume that feeds Saturn’s E ring (the planet’s second-outermost ring), is thought to come from a huge ocean of liquid water that sloshes beneath the moon’s icy shell. This discovery on its own was special because it meant that there might just be water on this moon, and if there’s water on it, there’s a chance we can colonize the moon as it would allow us to have easy (ish) access to water. But a deeper look at the plume itself revealed things that weren’t expected.
For example, dihydrogen (H2) and a variety of carbon-containing organic compounds, including methane (CH4). The dihydrogen and methane are particularly intriguing to astrobiologists. The H2 is likely being produced by the interaction of rock and hot water on Enceladus’ seafloor, scientists have said,.

 Let’s get straight to the point: the reason why Venus and Mercury don’t have moons is: they are too close to the Sun. Of course, this might not be the only reason, but it’s perhaps the most plausible one, according to scientists. 
In the solar system, you will find interesting moons: some examples are Jupiter with Io, Europa, Ganymede and Callisto, Saturn with Titan and Enceladus, Neptune and its Triton, Pluto, and Charon…but no moon has ever succeeded in becoming a moon of Mercury or Venus. To understand why this is, let’s take a look at other planets first, and let’s see how their moons formed or got captured, ending up orbiting around the planets in our solar system. 
===

The planets Mercury and Venus do not have moons of their own, unlike other planets in the Solar System. 

As Mercury and Venus are so close to the Sun, their gravitational fields are not strong enough to hold onto any moons that may have formed in the early Solar System. 
Although these 2 planets do not have moons, our Solar System is full of other objects that are in orbit around them. The most notable of these objects are a group of asteroids known as the Venus-Mars Trojans. These asteroids are in orbit around the two planets and share their orbits. However, it is really hard to spot Venusian asteroids, because of their close proximity to the Sun. A few searches in the Trojan region of Venus have so far reported no detection of stable Venus asteroids around the L4 and L5 Lagrangian points, called trojans. Most authors concluded that any population of primordial Trojans around Venus would have disappeared by now.
