What If You Lit a Match on Jupiter?



Atlas VPN 3-year offer with a 86% discount;

Jupiter is the largest planet in the Solar System. It’s 300 times more massive than Earth. But it’s less dense than our home. Uh-oh. Looks like somebody left the gas running on Jupiter. Don’t do anything stupid, like lighting a humongous match. What would a match need to be made of to ignite the gas giant? How big would it have to be? And how much damage would this explosion do to our Solar System? Would phosphorous be enough to cause an explosion on Jupiter?

What Is Our Place In The Milky Way?



What is our place in the Milky Way? And our place in the Universe? In ancient times, many people had the idea our planet Earth to be at the centre of the Universe, as stated by Aristotle and Ptolomeus in their ptolemaic – aristotelic concept of universe: according to this model, Earth is at the center of the universe and all the other celestial bodies orbit around it. Today lots of people think the same. But is this really the case? To answer this question, let’s try to to a travel in the universe, through space and time; we will start our travel from our planet to reach, in the end, the extreme boundaries of the universe.

During the 1600s, Galileo Galilei, the famous Italian astronomer, was one of the first people, during modern age, to have some doubts about the geocentric model of universe: thanks to telescopic observations, he was able to demonstrate our Earth is not at the rotation centre of planets and the Sun, but really it is the Sun itself. Moreover, observing planet Jupiter, he discovered that the giant planet is the rotation center for its moons. So, Galileo became aware that the center of the Solar System was the Sun, not the Earth!

The Solar System is made by a star, the Sun, eight planets and different types of minor celestial bodies, like comets, asteroids and dwarf planets.
Well, the Earth isn’t at the center of the Solar System, maybe is the closest planet to our Sun? No it isn’t, because it is only the third planet from the Sun: the closest planet to our star is Mercury, followed by Venus and then Earth. The Earth moves around the Sun, our star, just like all the other celestial bodies in the Solar System do: this implies that the Sun, and not our planet, is the center of rotation of the Solar System! The Earth takes a year, 365 days, to travel its orbit, and its average distance from the Sun is 150 million kilometers, which is the measure unit of distances in the Solar System known as the astronomical unit and abbreviated AU. Why do we talk about average distance? Because the orbit traveled by the Earth around the Sun is not circular but elliptical, and this means that there will be an aphelion (i.e. the point of the Earth’s orbit farthest from the Sun, just over 1 AU away from it) and a perihelion (the point of Earth’s orbit closest to the Sun, just under 1 AU). An alternative way to define the astronomical unit passes through the light time, in particular we can say that the average distance Earth – Sun is equal to about 8 light minutes: this means that sunlight takes 8 minutes to arrive on Earth, so that the sunlight we see at a certain moment is not that of that moment but it is the sunlight which left from the Sun 8 minutes earlier! In other words: if the sun went out for example at 2.30 pm, we would only notice it at 2.38 pm! Or again: if you could travel aboard the Star Wars Millennium Falcon it would take you only 8 minutes to travel from the Sun to the Earth (when in reality it takes a few years). To give a more concrete idea of the dimensions of the Solar System: if the Sun were a sphere with a diameter of 14 cm, Pluto would be at 700 m from the Sun, like seven regular soccer fields!

The nearest celestial body to Earth is the Moon, our satellite: to reach it you should take three days off! It’s the same time taken by Apollo astronauts to cover the distance of nearly 400 thousand kilometers that separate Moon and Earth. But if you had Star Trek Enterprise, and travel at maximum curvature, you would only take less than 2 seconds to reach the Moon!

Io: Jupiter's Volcanic Moon!



From the discovery of the moon, to what makes it so volcanic, and more! Join us as we explore Io: Jupiter’s Volcanic Moon!

8. The Discovery Of Io
In many ways, Io is one of the more popular moons of Jupiter. It’s been referenced many a time as we’ll note later. But how did we learn about this very special moon?
The first reported observation of Io was made by Galileo Galilei on 7 January 1610 using a 20x-power, refracting telescope at the University of Padua. However, in that observation, Galileo could not separate Io and Europa due to the low power of his telescope, so the two were recorded as a single point of light. Io and Europa were seen for the first time as separate bodies during Galileo’s observations of the Jovian system the following day, January 8th, 1610 ( this is used as the discovery date for Io by the IAU).
The discovery of Io and the other Galilean satellites of Jupiter was published in Galileo’s Sidereus Nuncius in March 1610. In his Mundus Jovialis, published in 1614, Simon Marius claimed to have discovered Io and the other moons of Jupiter in 1609, one week before Galileo’s discovery. Galileo doubted this claim and dismissed the work of Marius as plagiarism. Regardless, Marius’s first recorded observation came from 29 December 1609 in the Julian calendar, which equates to January 8th, 1610 in the Gregorian calendar, which Galileo used. Given that Galileo published his work before Marius, Galileo is credited with the discovery.
But the end of the “discovery” did not end there. Because for basically 250 years various astronomers tried to learn more about Io. But because of its place in space all they could usually see was a ball of light. It would take a while for them to start to parse out the details of the moon.
Improved telescope technology in the late 19th and 20th centuries allowed astronomers to resolve (that is, see as distinct objects) large-scale surface features on Io. In the 1890s, Edward E. Barnard was the first to observe variations in Io’s brightness between its equatorial and polar regions, correctly determining that this was due to differences in color and albedo between the two regions and not due to Io being egg-shaped, as proposed at the time by fellow astronomer William Pickering, or two separate objects, as initially proposed by Barnard. Later telescopic observations confirmed Io’s distinct reddish-brown polar regions and yellow-white equatorial band.
Telescopic observations in the mid-20th century began to hint at Io’s unusual nature. Spectroscopic observations suggested that Io’s surface was devoid of water ice (a substance found to be plentiful on the other Galilean satellites).
So as you can see, this wasn’t just a discovery of trying to find the moon, but to try and understand what it was and what it was like in regards to its very nature. Which would be further expanded upon in the future via attempts to explore the moon with probes and satellites.
7. The Exploration of Io Part 1
In the late 1960s, a concept known as the Planetary Grand Tour was developed in the United States by NASA and the Jet Propulsion Laboratory (JPL). It would allow a single spacecraft to travel past the asteroid belt and onto each of the outer planets, including Jupiter, if the mission was launched in 1976 or 1977. However, there was uncertainty over whether a spacecraft could survive passage through the asteroid belt, where micrometeoroids could cause it physical damage, or the intense Jovian magnetosphere, where charged particles could harm sensitive electronics.

What If Earth Was Spinning at the Speed of Light?



The Earth makes one full rotation on its axis every 23 hours, 56 minutes and 4.1 seconds. And it’s not moving at the same speed everywhere. The rotational speed varies depending on your distance to the poles. This rotation makes Earth suitable for life. The diurnal cycle, or the shifting between day and night, helps keep the planet at a habitable temperature. Earth’s rotation is the driving force of weather patterns. Even tides are affected by the Earth’s spin.

So if we were to accelerate this rotation, would we completely destabilize the climate? What would happen to the length of our day? What geographical and climate changes would occur? And at what point would life on Earth cease to exist?

Why  Space Research  Is So Important!

Why Space Research Is So Important!

In recent years, people’s interest in all countries on the planet in space exploration has soared.
Many controversies have been raised regarding whether money should be spent on Space research while there are many problems in our inhabited planet, earth and especially in Humanity. There is poverty, financial issues. And still so much attention into Space exploration. Why?
Join me I show you reasons why Space research is very important.

——————————————————————————————-
We have seen NASA announcing findings in other planets, solar systems and companies such as SpaceX undergo space projects. For instance we have determined the approximate age of the universe, we found water on Mars, we discovered the first exoplanets in 1992, between the years of 2004 and 2005 three new dwarf planets that exist in our solar system came into our attention and so much more.
But many keep on claiming. What is the point in all of this?
In order for a space exploration to happen, much money needs to be spent. For this reason many people seem to raise questions when it comes to space exploration whether money should be spent on space missions while there are many issues that are happening in our planet that we haven’t solved, and need financial support. So instead of exploring space, money should be spent for Earth’s needs.
Some others consider that, since we already visited the moon in 1969, we don’t need space travel anymore. isn’t it enough?
Well, there are many reasons why space exploration is important and I will try to explain my point of you on this topic and why space research is more significant than we think and vital to humanity.
Before we continue with the significance of space exploration, be sure to like or dislike the video so that we can continue improve and make these videos better for you the viewer. Plus, be sure to subscribe to the channel so that you don’t miss any of our weekly videos!

Now let’s start analyzing our topic.
Well Universe!
Can you imagine the feeling the astronauts who first landed on the moon must felt looking back at the earth? Breaking through into space travel, leaving earth and defeating gravity, taking steps on the moon?
I bet the feeling would be unique! As they had the opportunity to see earth from a distance and be the first ones to acknowledge it! Imagine being in there position! I think many are jealous that they didn’t live this experience. For them this incident can’t be compared with anything else, and while we didn’t know at this time, this mission advanced our Humanity, and raised the interest on figuring out the Universe! Only goo results can come out of this as we are learning who we are and becoming strong.
But what is the real motive behind exploration. Why do you want to explore and go out of our comfort zone instead of carrying only about what is going on on Earth?
Well, the main reason why moon landing happened in 1969 and, is because humans are driven to explore the unknown, discover new worlds and push the boundaries of the scientific limits. Like it or not, we are by nature explorers who want tο push further and challenge the boundaries of what we already know and we want to learn always something new that can cause a whole new reality. We love exploring the world, travelling abroad visiting other countries and places, collecting memories and experiencing feelings. The same happens on a bigger level by exploring the universe. We are never satisfy and we always want more. People try to achieve these feats for reasons that are not necessarily rational. A few years ago we confirmed the existence of dark matter and we couldn’t do that without space exploration. What is the value of this knowledge? It’s hard to guess today.
And what keeps us going is the fact that we can discover everyday something new and in this way we advance human race. Imagination remains our most powerful attribute and we don’t want to stay stable in only one thing. That is what we do. We always explore. We overcome obstacles not because we have to, but because we want to. We can’t live without progress and curiosity is in our blood.
In this point we need to make clear that exploration isn’t just only about curiosity though, as exploration is necessary for advancement in general. If it wasn’t for the Space exploration we wouldn’t have advanced technologies.
The space research has led us to expand our scientific knowledge and have development of various technologies that improve our lives on Earth and also the economy. The world that we have created today, is the result of several years worth of knowledge, much of which has been built through exploration.

9 Strangest Galaxies In The Universe!

9 Strangest Galaxies In The Universe!

Subscribe for more videos:

From galaxies that are shaped weirdly, to ones that have unique properties, join me as I show you the strangest galaxies in the universe!
9. ESO 137-001
I want you to think about the “shapes” of universes. Depending on the pictures you look at, you likely think of things like the spirals that many galaxies are believed to be shaped as. But in the case of ESO 137-001, that isn’t exactly the case. Because this galaxy…is shaped like a Jellyfish.
No, really, the spiral form of the galaxy is still there. BUT, it also has a “tail” that is formed by stars that are in its “wake” if you will, and it’s quite a tail as it extends over 260,000 light years into space!

8. NGC 1052-DF2
Ok, this one was weird in context as I’ll explain. You see, in 2018, the Hubble Space Telescope (one of the most important pieces of technology we have in terms of mapping space) found a galaxy known as NGC 1052-DF2. When scientists and astronomers looked at the galaxy though, they felt that something was missing. Mainly, there was a lack of Dark Matter, and that should’ve been impossible.
“Dark matter is conventionally believed to be an integral part of all galaxies — the glue that holds them together and the underlying scaffolding upon which they are built,” explains co-author Allison Merritt from Yale University and the Max Planck Institute for Astronomy, Germany.

7. MACS 2129-1
The place known as MACS 2129-1 is definitely a galaxy that stands out for a whole host of reasons. Not the least of which is because it’s what’s known as a “No life Galaxy”. To be clear, there is life in the form of stars and planets within it, that’s not the issue. But, the galaxy is no longer “active”, meaning that it’s not making anymore stars despite it being over 10 billion years old.

6. The Andromeda galaxy
Arguably the most famous galaxy in the universe outside the Milky Way, the Andromeda Galaxy is one that has led many people to wonder what is just outside our own galaxy, mainly because it’s our neighbor. Not just that, it’s our largest neighbor by a wide margin, and there’s a very good reason for that. Mainly, the Andromeda Galaxy is known as a “cannibal galaxy”.
What does that mean? Well, as the title describes, it actually collides with and devours other galaxies in order to make itself bigger:
“Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalized many more galaxies, possibly larger ones,” lead study author Dougal Mackey, an astronomer at Australian National University, said in a statement. “Knowing what kind of a monster our galaxy is up against is useful in finding out the Milky Way’s ultimate fate.”

So, remember the Jellyfish Galaxy we talked about a little while ago? Well, meet its cousin, the Tadpole Galaxy. This one is very on the nose in terms of its name because of the fact that it has a LONG tail that is attached to a body that reminds scientists of a tadpole. So looking at this you may wonder, “How did this happen?” According to the ones who found it, it’s a remnant of sorts from a galaxy that collided with another.
4. W2246-0526
If this list has shown you anything so far, it’s that the state of our universe is very much in a state of flux. But what you might not realize is that while some galaxies do collide with each other, others go and just steal things from one another. They alter shapes, steal stars, and sometimes even become brighter. Which is the case with W2246-0526:

3. Little Cub
Found in the Ursa Major Constellation, there is a dwarf galaxy known fondly as the “Little Cub”, and it’s one that has scientists very curious despite its impending doom. Why is that? Because the “Little Cub” as it is known is a galaxy that is dormant, and it has remained unchanged for about 13.7 billion years. If you know the alleged history of the universe, that would mean that it has been the same since the beginning of the universe more or less.

2. The Petal Galaxy
Let’s dig back into the visuals of galaxies for a bit. There are many galaxies out there in the universe that are growing at various rates as we’ve shown. But ESO 381-12 is different. Not only is this one growing, it’s growing in a way and in a shape that is truly baffling scientists. How so? Well, it looks like a flower in bloom, and the “petals” as they are known aren’t symmetrical.

1. Messier 83
15 million light years away in the Hydra is the galaxy known as Messier 83, and it is a galaxy that has caught a lot of people’s eyes. Mainly because those who have looked at it noticed that it has “two hearts”:

8. The Scope Of Our Own Solar System
Before we look beyond it, let’s take stock of our own solar system and what it all is like. There are 8 definitive planets (and more than that if you count Dwarf Planets like Pluto), we have one star, The Sun, that we orbit around, and within the confines of our system are asteroid belts, various rocks of various sizes, tons of solar rays and radiation, and a whole lot more.
Just in our solar system there is a LOT of stuff to explore. Which is sometimes hard to find because the length of our solar system is about 287.46 billion kilometers long. And even in the year 2020 we’re STILL finding out things about our solar system that are shocking and surprising. But of course, the main goal of humanity as a whole is to do what many have thought is unthinkable. To go BEYOND our solar system and to not just see it, but explore it, and live upon it. To truly become a species that is intergalactic instead of just living in one very small part of the universe.
7. What Lies Immediately Beyond Our Solar System
So let’s posit for a moment that you are able to go and get out of the reach of our solar system. Behind the Kuiper Belt, beyond the Heliosphere, what are you going to find when you reach that edge beyond? What will you see? What will you experience?
The honest and very simple answer…is nothing. Because you’ll be in what is known as Intergalactic Space. Or, the space between galaxies and systems. But to be clear, just because you don’t see anything, doesn’t mean that nothing is there.
“If you took a cubic meter, there would be less than one atom in it,” Michael Shull, an astronomer at the University of Colorado Boulder, told Live Science. “But when you add it all up, it’s somewhere between 50 and 80% of all the ordinary matter out there.”
Scientists are honestly deeply interested in this matter, or “Intergalactic Medium” because of how they feel it forms and even replenishes certain systems via the gas that it provides. The reason for this is that the medium is mostly hot, ionized hydrogen (hydrogen that has lost its electron) with bits of heavier elements such as carbon, oxygen and silicon thrown in. While these elements typically don’t glow bright enough to be seen directly, scientists know they’re there because of the signature they leave on light that passes by.
“IGM is the gas that feeds star formation in galaxies,” Shull said. “If we didn’t still have gas falling in, being pulled in by gravity, star formation would slowly grind to a halt as the gas [in the galaxy] gets used up.”
But because of its small numbers, when you’re floating through space, you’re almost literally floating through empty space. Which is why many note that all the planets and stars and celestial objects only fill up about 5% of the known universe. Everything else is minor matter, Dark Energy and Dark Matter.
6. Systems Beyond Our Own
Ok, so let’s say that you are able to reach another system. What would it be like? Well, that would depend on what you land upon.
Because there are at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across. The stars are arranged in a pinwheel pattern with four major arms, and we live in one of them, about two-thirds of the way outward from the center. Most of the stars in our galaxy are thought to host their own families of planets. Thousands of these extrasolar planets (or exoplanets) have been discovered so far, with thousands more candidates detected and awaiting confirmation. Many of these newly discovered planetary systems are quite different from our own.
In fact, part of the fun of astronomy in the eyes of many is going and seeing if you can indeed find a new planet, or star that hadn’t been noticed before, and seeing what details you notice about it. In fact, various agencies from NASA to the ESA and more have made their own satellites and probes and such that they’ve launched into space or our atmosphere to try and get better looks at planets and stars and see what we can find.
Some of the highlights for sure are many planets that are “Earth-Like” in structure or form or shape. Numerous kinds of stars from dwarf stars to binary stars, to Pulsars, Supernovas and more. They’ve found black holes at the center of most galaxies, and that’s still only scratching the surface of things.
