Constructing the largest telescope

#construction #telescope #space #astronomy #planets #ELT #Europe #Chile #stars

The European Extremely Large Telescope (ELT) is being built in Chile, and when completed, it will be the world’s largest optical telescope (about five times larger than current ones). The main mirror of the telescope will measure 39 meters across and will be located on a 3,000-meter-high mountain in the Atacama Desert. It will begin operations in 2024. The construction costs are estimated at $1.12 billion.

The telescope will have the ability to find smaller planets and image larger ones, going as far as characterizing their atmospheres. This is being considered one of the greatest examples of the possibilities of science, and will help in discoveries of planets orbiting other stars, which in turn might be exo-planets.

Atacama Desert was chosen because of its dry atmosphere that provides perfect observing conditions. By the 2020s, the region will have almost 20 percent of the World’s astronomical infrastructure.

A telescope with better range and clearer observation. A great chance for humanity to know more about space & universe, spot some exoplanets, and some aliens.

Skyview App

#space #Skyview #Application #Stars #Planets #StarGazing #constellations

An amazing application! If you want to know more about the stars in the night sky that can be viewed from the naked eye, then do check it out. It also tells you where the planets are.

It can calibrate itself to your location and if you use the app on the night sky, it will point out the stars, constellations and other information by using the camera of your phone.

Pretty interesting. I had been wondering about a star in the sky, turns out it is named Capella in the Auriga constellation. 😊

A glimpse into early universe

#Galaxy #space #telescope #stars #planets #BigBang #MACS1423

A galaxy almost 13.1 billion years in the past has been discovered by astronomers, an era just 700million  years after the Big Bang. These early galaxies were close to the beginning of the universe, hence they fall within the “Epoch of Reionisation“, a period about a billion years after the Big Bang when the universe became transparent.

It is believed that the universe was a cloud of cold atomic hydrogen after the Big Bang. The first stars and galaxies condensed out of the cloud and started emitting light and ionising radiation. The radiation melted away the atomic hydrogen like a hot sun clearing fog, and the first galaxies spread their light through the universe.

The new galaxy is named MACS1423-z7p64, is at a redshift of 7.6, which means that it is about 13.1 billion years in the past.

What is with the name of the galaxy? Its amazing, how new discoveries are making us learn more and more about the universe.

Freedom, With wings

She flew like a fairy. The wings were real! So light yet so big that they could envelope her in their softness.

Slowly, she rose above the ground, her wings moving back and forth so gracefully and quietly that you would keep looking at it in awe and won’t even hear a sound. She felt like the whole world could see her now and can taste the happiness she spread.

Her boyfriend looked at her face and said I love you. She had tears in her eyes, but this just encouraged her even more to fly higher.

She looked upwards and saw the vast night sky. Strangely there was not even a single cloud in the sky, but she could swear that she could feel the drizzle on her face just a while back.

She closed her eyes and flew, still facing upwards. She flew as high as she could, leaving the darkness behind and spreading a strange light from her wings, a light that formed a path from where she had stood just a while back right up to her current position. She admired the sight in the night and still flew up, making that path bigger and bigger.

She was high enough, enough to see airplanes at her level. What should she do? Should she fly higher or will that be too risky. She didn’t know what to do.

She saw a airplane going adjacent to her and from one of the windows, she could see a young girl, probably sitting in a business class seat, looking upwards at the sky. She guessed that she might have been counting the stars. Looking at that young girl, tears rolled down her eyes. Wasn’t that her dream? To observe the stars and reach them if possible? Why was she hesitating now when she had a chance? Was she that wrapped up in life that she had forgotten what she dreamed about and what she wanted to live for. The airplane passed her.

She looked up again, at the clear sky and saw the stars. Was something there? How could they shine so brightly? It was the same light that was coming out of her wings. This made her all the more curious and her instinct told her to go for it. She remained there for five minutes, contemplating whether to go or not. Her mind was resisting, because it was scared or it was just too satisfied to try anything new. She looked up and smiled. I want to see.

She flew higher up, exiting the atmosphere of the earth. But this time, it was not a slow ascend, like the speed of a Concorde. She flew like no one else, covering such great distances in a snap. It was as if her speed had magnified along with her will to move forward. She kept on flying up, leaving this world of humans and into that world of stars.

Back at home, her boyfriend saw a bright light coming out of her girlfriend’s body, that was still sleeping on his lap. He could now see the path. This made him smile and he thought, “Be free. Fly as high as you can because I know that you are strong enough to do it. I will still love you, and I wish you don’t forget me either, wherever you go. And if possible, someday we will meet again so that you can tell me all about your journey. Because even then, I would love to hear anything that is about you.”

Suddenly, like a miracle, the bright light covered her entire body and after a second, exploded into small shiny particles that faded away within seconds. The only thing left behind were her clothes and the crutches. Although he saw another thing, a pendant,  he hadn’t seen it before. It shone with the same light and intensity as the path just minutes ago. The shape of the pendant showed an angel with her wings wide open and looking upwards towards the sky. He smiled, and looking upwards, whispered, “Goodbye. Love you.” He took the pendant and wore it around his neck, the light still coming out of the extraordinary jewel. “Maybe this means that we will still be connected, however far we go”, he thought.

He then folded the dress and kept it in her cupboard.
