Is there a way to get to space without a rocket ?

Since the dawn of astronautics the only method we have to reach space is using rockets .To determine the quantity of fuel needed to bring an object into orbit scientists use a famous equation  called ‘’the equation of the rocket ‘’.

EVERYTHING IN OUR UNIVERSE HAS A LIMIT

 

Everything in our universe has a limit. It may seem obvious, but it is something worth-considering. If everything has a limit, than there’s no such thing has “infinity”. Something without a limit cannot exist, because it is incompatible with our own reality. We know that there’s a limit to how cold something can get: that’s 0 Kelvin degrees, the minimum possible temperature. We know that there’s a limit to how fast something can go: that’s 300 000 000 meters per second, the speed of light. And we know that there’s a limit to how much of the Universe we can see and interact with.

MARS 2020: SEARCHING FOR LIFE ON MARS

Mars 2020 is a space mission developed by NASA for the search of ancient life clues on Mars . The mission consists of a rover named Perseverance and a small helicopter named Ingenuity . Perseverance has a similar design to its predecessor rover Curiosity but comprises some technical improvements and a lot of devices to investigate on bacterial life .

THE LIMITS OF HUMANITY

The Large Magellanic Cloud  , a galaxy which belongs to the Local Group 

With our current technology sending a human to the closest star will take thousands of years. Even assuming that humanity will become a type 3 civilization ( an example of type 3 civilization is the galactic empire in the Star Wars series ) there will always exist a boundary beyond which  we could never go further: the Local Group. The Local Group is the group of galaxies to which our galaxy belongs; it includes about 70 galaxies , most of which are small in size, which is 0.00000000001% of the observable universe .

EXOPLANETS

OUT THERE

We live in a thin spherical shell a few kilometers thick around the surface of the Earth . Even if we explore the deepest abysses in the ocean or climb the most impervious peaks of Himalaya , our reign has ridiculous dimensions .Our little world is also populated by ghosts : we think that everything we perceive is real but as we stray a little from the quite place where we live , everything we know changes . If we want to explore the secrets of the universe we must renounce these certainties preparing for the unthinkable . The research of exoplanets represents one of the last frontiers of modern science ….follow me on this wonderful  journey .

ARE WE ALONE?

Hi everyone! Today I want to start asking you a question: how big is the universe? “Huge” many of you will answer. And  that’s true! Our universe is enormous, maybe even infinite.  And from our small planet, we can only see a tiny portion of it. So, if it is so big, then it should be reasonably full of life, right? I mean, statistically speaking is very improbable that ours is the only planet in the entire universe in which life flourished. There must be others.

IS IT POSSIBLE TO LIVE NEAR A BLACK HOLE?

If you have seen the renowned film "Interstellar", you probably remember the  protagonists leaving the earth in search for an inhabitable planet near a super massive black hole, but you must know there’s a major mistake in all that.  

 A  research directed by NASA astrophysicist, Jeremy Schnittman,  explains it. In his work Schinttman analyses the probability to find an inhabitable planet at  the right distance from the black hole, in the livable area , heated by the accretion disk . Would you like to know what the mistake in the movie is? You can’t live near a black hole because of the light. What does that mean? The light  I refer to is the light that comes from the surrounding stars . To understand it,  we have to imagine the  gravitational , and in general physical  effects caused by this massive object. First of all the different passing of time. According to Einstein's  relativity , when you are close to an object with a huge mass, the time flows faster . Few hours near the black hole are many years in interstellar space. The second one is the reason why you are reading this article ....  charged particles accelerated by the gravity.

NASA SPITZER SPACE TELESCOPE CAPTURED AN AMAZING IMAGE. WHAT IS IT?

Hello everyone,

look at this picture...space bubbles! Nasa Spitzer Space Telescope captured this image of burning, bubbling star formation in the Cat's Paw Nebula. As gas and dust compress to form stars, the gas around these areas heats up and pressurizes, giving them the appearance of bubbles. Radiation from the hot stars also causes these bubbles to glow brightly. Spitzer is an infrared telescope which can help scientists to see through thick clouds of gas and dust in ways our eyes cannot. What do you think about it? What's your favorite nebula? Tell us in the comments.
