Where Are Stars Made? NASA’s Spitzer Spies a Hot Spot in Milky Way

Published

NASA’s just lately retired Spitzer Space Telescope has given us the most recent take a look at the nebula and what it seems like.

The most massive stars in the universe are born inside cosmic clouds of gas and dust, where they leave behind clues about their lives for astronomers to decode.
Ever since we began studying concerning the universe and the interstellar house, we now have heard about stars. But there have been questions on how these stars are born and the way their native place seems like. Well, it was first found in 1958 by radio telescopes that’s a nebula often known as W51 is among the most energetic star-making areas in our Milky Way galaxy it makes a rich cosmic tapestry in this image from NASA’s recently retired Spitzer Space Telescope.


Located about 17,000 light-years from Earth, in the direction of the constellation Aquila in the night sky, W51 is about 350 light-years – or about 2 quadrillion miles – across. It is almost invisible to telescopes that collect visible light (the kind human eyes detect), because that light is blocked by interstellar dust clouds that lie between W51 and Earth. But longer wavelengths of light, including radio and infrared, can pass unencumbered through the dust. When viewed in infrared by Spitzer, W51 is a spectacular sight: Its total infrared emission is the equivalent of 20 million Suns. However, it isn’t straightforward to identify the nebula in the evening sky with telescopes that accumulate seen gentle. This is as a result of the sunshine between W51 and Earth will get blocked because of the presence of mud clouds fashioned in the galaxy. Using radio, infrared or longer wavelengths of sunshine can assist us discover the nebula. This is how the infrared wavelength of NASA’s Spitzer telescope helped in capturing the sight of W51.

If you could see it with your naked eye, this dense cloud of gas and dust would appear about as large as the full Moon. The Orion Nebula – another well-known star-forming region and a favourite observing target for amateur astronomers – occupies about the same size area in the sky. But W51 is actually much farther from Earth than Orion and thus much larger, and it’s about 75 times more luminous. While Orion contains four known O-type stars – the most massive stars in the universe – W51 contains over 30.


“Star factories” like this one can operate for millions of years. The cavernous red region on the right side of W51 is older, evident in the way it has already been carved out by winds from generations of massive stars (those at least 10 times the mass of our Sun). The dust and gas in the region are swept around even more when those stars die and explode as supernovas. On the nebula’s younger left side, many stars are just beginning to clear away the gas and dust in the same way the stars in the older region have done. It’s apparent that many of these young stars are in the process of forming bubbles of empty space around themselves.


This image was taken as part of a major observation campaign by Spitzer in 2004 to map the large-scale structure of the Milky Way galaxy – a considerable challenge because Earth lies inside it. Called the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE), the survey also turned up valuable data on many wonders within the Milky Way, including images of multiple stellar factories like W51 that were hidden by dust from visible-light observatories.


“The really spectacular images provided by Spitzer via the GLIMPSE survey ¬– in concert with data from many other, complementary telescopes – give us insight into how massive stars form in our Milky Way, and then how their powerful winds and radiation interact with the remaining ambient material,” said Breanna Binder, an assistant professor of physics and astronomy at California State Polytechnic University, Pomona, who studies the life cycles of massive stars. “We can’t observe star-forming regions in other galaxies in anywhere near the level of detail that we can in our own galaxy. So regions like W51 are really important for advancing our understanding of star formation in the Milky Way, which we can then extrapolate to how star formation proceeds in other, nearby galaxies.”


NASA’s Spitzer Space Telescope launched 17 years ago this week, on Aug. 25, 2003. The spacecraft was retired on Jan. 30, 2020. Though the mission has concluded, the entire body of scientific data collected by Spitzer during its lifetime is available to the public via the Spitzer data archive, housed at the Infrared Science Archive at IPAC in Pasadena, California.


NASA’s Jet Propulsion Laboratory, a division of Caltech, managed Spitzer mission operations for NASA’s Science Mission Directorate in Washington. Science operations were conducted at the Spitzer Science Center at IPAC at Caltech. Spacecraft operations were based at Lockheed Martin Space in Littleton, Colorado.

Dussehra: Victory of Good over evil

Published

on

Dussehra: Victory of Good over evil, is celebrated on the 10th day of month Ashvina. Victory means Prabhu Rama over Ravana in famous hindu epic Ramayan. Also it means the end of Durga puja and Ramlila. In Ramayan, Ravana kidnaps god Rama’s wife Sita, as god Rama & Laxman cuted of the nose of ravna’s sister surpanakha. So to claim vengeance on them Ravana kidnapped sita. To get back maa sita Prabhu Rama and Laxman faught battle against Ravana with the help of hanuman, Subriv & other Vanar sena.

In this battle Ravana’s brother Bhibishan also helped god Ram against Ravana . At the end of Prabhu Ram wins the battle and rescues Maa Sita. Thereafter this victory is celebrated by burning the statue of Ravan, Kumbhakarn, his son Meghnath. Dusshersa is a climax of long day celebration of Navratri.

Navratri:

           The nine days of Navratri is the time to reflect on oneself, observe silence & practice fasting. Fasting cleanses the body of toxins and silence purifies speech & mind. What does Dasehra means Das means ten and hara means take away. Which came after Navratri means nine nights if darkness.  On each day of Navratri we pray to that form of goddess durga to take away that darkness of ignorance within us. After that on tenth day on the occasion of Dasehra we burn all the evil, bad things, thoughts, bad habits inside us in that fire in the form of Ravna as evil inside us.

Dusshera: Victory of Good over evil

Ravana is not the demon or evil, you yourself are one. In the battele of Ram and Ravana, god Ram had been invoked Durga May to help him win the battle against Ravana. We also should invoked Durga to help us in gaining back our Sita. Sita?  It is awareness inside is which has been traped in maya surround us. To make our soul clean and pure we have to burn the evil in the fire by fighting and winning battle against evil. many evils and negative aura lives within us, we should overcome this with good things. This is what Dasehra symbolise.

It is a supreme festival of Hindu culture with true meaning. Furthermore it also symbolize the feminism as the battle is to bring back maa Sita from the Ravana. Whenever person crosses his limit, go beyond it and try to hurt marayda of stree. She will transform into Durga and will punish that person to death. Rama won the battles and the light and happiness spreaded. its our choice, either we want to be Ravana & get entrapped in the worldly pleasure or want to Rama (A spiritual being).To symbolise and to aware Dashera is celebrated do its called, Dussehra: Victory of Good over evil!

Published

on

Priyadeep Kaur is a published author at age of 19. She is the transpiring novelist and her work has been sighted by Shri. Narendra Modi – Prime Minister of India. Priyadeep spent her antecedent days in Shiv Ki Nagari Kashi – Banaras. She is proficiently known as Kashi Ki beti in her hometown. She is awarded with Uttar Pradesh (U.P) Gaurav, Atal Samman 2018, and the title Shaan-e-Kashi. 

More about Priyadeep:

Priyadeep currently is staying in the ‘City beautiful’- Chandigarh. She furthermore worked with a national TV channel of Rapper Badshah. ‘Millions Of Faces in a Face’ is her first book, which received massive love from readers especially from youngsters.

Her second book named Oscar for loving, Grammy for Not! is listed as the best-selling book on the amazon and she grabbed the best-selling author title. Apart from studies she was also highly interested in extracurricular activities during her school days and now Priyadeep Kaur is a published author at age of 19.

Q. When did your journey into writing began? 

Priyadeep: “I am fond of writing back from school days. My grandmother passed away, I found dairy of dad- he had written a poem dedicated to his mom. The poem was very heart touching and emotional. So, I felt like I should also start writing, then I started writing small poems and about things happening around. Then I also started writing parodies on teachers just to express my thoughts. When I was in grade 10, then I started compiling my writings together. That time I use to read novels from ‘Chetan Bhagat’, ‘Nikita Singh’ and from many other novelists too. So, at that time I thought should try writing a book. That’s how the journey started.”

Q. When did you realised that you should be a writer and your writing should get published?

Priyadeep: “Actually, as soon I completed my first book writing, actually I started writing that book when I was in the 11th grade. So, I at that time it was bit hard for me to get things done in a commercial way to get my book published and it took lot of time for that. Then I started doing research how to get book published and I also mailed my work to many publishers. So, I got few replies and with one of the publishers I got my book published. And soon it was available for reading.”

Q. What was the most surprising thing you learned while writing novels?

Priyadeep: “I learnt my things from my novels and one thing I want to mentioned is – there is very slight difference between the things we imagine and things which really happen. I think people who are into writing are a kind of overthinkers, they think a lot. They think from different perspective and try to create an anonymous situation out from it. Being writer, I imagine many things but they are not into real life. So, its very important to keep imaginary world and real life separately and keep the things sorted.”

Q. A person can’t be a writer if he/she doesn’t have strong emotion, what are your views?

Priyadeep: “I would not agree on this personally, but a person can be a writer if they are not good grammar, even if they are not having a particular knowledge of language and to portrait things. Emotions are necessary for writing; we need to feel the situations in that particular way. Although very body has emotions it’s not necessary that to be a writer you should have strong emotions, with time and practise you can achieve it. I agree emotions play a vital role in writing and every one of us have emotions and everybody can write.”

Q. What was your childhood dream?

Priyadeep: “I wanted to be singer actually, that was my childhood dream. When I was 4 years old, my dad introduced me to pandit Anurag dixit. He uses to conduct my classical music classes and I was fond of performing in school and at many other places. So later I started to go in shows and started performing at very small age. I also used to sing local songs at that time. Since 12 grade I started performing- singing and also recorded few songs. At that time, I was also busy into writing and getting book published. So, writing made me feel somethings, like that’s what I want to be. So, I continued by writing.”

Q. What are the techniques and strategies you keep in your mind while you are writing?

Priyadeep: “Actually I try my best to justify the title, which I have given to the book. I think title should be always justifying. Then draft your story accordingly so you can keep the track of it. So, I make the points and draft and then start writing the book, so it’s easy for me if I need to add on few things in between. Mainly I focus on the words and vocabulary add it accordingly. I prefer to sketch the character and his nature, so its easy to maintain and build the story.”

Q. Generally how long does it take to complete a book?

Priyadeep: “My first book I completed in six months. And it took lot of time to complete my second book, because I have joined the office and started working at production house in Chandigarh. Now I am launching my next book, so it took me around 3 months to complete it, which I stared writing during lockdown. So, it’s in pipeline and will be out soon. Although it depends on the time and story to complete a book, it may differ from writer to writer.”

Q. How was your experience working with Badshah sir as a creative producer?

Priyadeep: “It was a very nice experience; I had a wonderful time with the team. We also shoot few songs and I learned lot of things about real life and reel life. I determined the people are so much different in real life, then we usually see in reel life. Specifically talking about BADSHAH sir, as we see his personification in songs, he is completely different in real life. He is very sweet, innocent and humble person. In real, he is not much interested into parties. He is very hardworking and fully dedicated to his work. The whole team was amazing, I got few friends too and the overall journey was awesome for me. I learnt many things from them.”

Q. Can you tell us about the moment when you meet Shri. Narendra Modi (Prime minister of India) and you and your work recognised by him?

Priyadeep: “It was an awesome moment for me, I am very grateful for that. Talking about my family they have framed the photographs and pinned to wall everywhere in my house. For them it was a very proud moment. For me it was a very happy and different kind of adventurous moment. I wrote a letter to PM office randomly and unexpectedly I got response to launch my book by him. I think that was one of the best moments as of now in my writing journey.”

Q. What are your future plans?

Priyadeep: “My next book is coming in November and I am also doing a freelance work in Chandigarh right now, it’s a project of 6 months. So, need to go to Ahmedabad for that work. I have completed two more books in lockdown so I will be planning about there editing and publishing. Due to covid I have many projects pending, so when things will settle need to complete the projects and shoots.”
