Milky Way around it.

Astronomers at the National Center of Radio Astrophysics ( NCRA) spotted galaxy AGC 203001 using the Giant Metrewave Radio Telescope (GMRT) in Pune. They found that even though the galaxy had a ring of hydrogen gas around it — there were no new stars being born. This is despite the fact that the ring is 380,000 lightyears wide, much bigger than the galaxy itself.

Where did the stars go?

Nobody knows where and how these rings of hydrogen gas form. The most popular theory is that they are a result of galaxy colliding into other galaxies, but even that’s largely debated.

In fact, there’s only one other galaxy discovered by scientists that’s has a hydrogen ring as big as AGC 203001, according to the study published in the Monthly Notices of the Royal Astronomical Society.

Normally, large reservoirs of neutral hydrogen gas around a galaxy are accompanied by new stars being born within its fold. The Eagle Nebula, for instance, is 5.5 million-year-old clouds of molecular hydrogen gas and dust.

Hubble Telescope

According to images taken by the Hubble Telescope, the clouds were dotted by clumps of gas — Evaporating Gaseous Globules (EGGs) — on their outer edges. Inside some of the EGGs were embryonic stars.

Galaxy AGC 203001 as more than enough hydrogen — even though it’s exact distribution isn’t known — but no new stars.

The team of NCRA astronomers even got some help as asked two French astronomers to take more sensitive images using the Canda-France-Hawaii-Telescope (CFHT) located in Hawaii. But even they didn’t turn up any signs of starlight.

What’s next?

There isn’t any clear explanation for why AGC 203001 is star-less despite having copious amounts of hydrogen gas. In order to find out why this is the case, the NRC team is now on the hunt for other such galaxies.

Comparison other such galaxies, with rings of neutral hydrogen gas surrounding them, to help scientists figure out how such rings come to exist in the first place — and why most have stars forming but AGC 203001 doesn’t.

Come on, that is an unwarranted response. They are at the level where they are sharing some of their achievements and look at us. We should be ashamed, not making fun.

Yes. With its two main stars, to be named Amit-1 and Yogi-1.

Campus connect: Radio astronomy winter school at Pune gives experimental learning experience to 30 students

As many as 30 students from across India are busy gaining hands-on experience and additional knowledge through the radio astronomy winter school which is a joint initiative by NCRA - TIFR (National Centre for Radio Astrophysics and Tata Institute of Fundamental Research) and IUCAA (Inter University Center for Astronomy and Astrophysics). The sessions are annually held in the month of December and is alternatively conducted by the two institutions. The eleventh batch of students this year have been attending sessions from December 14 which will go on till December 24.

The joint collaborative initiative was started in 2007 and the Radio Physics Laboratory has been conducting the Radio Astronomy winter schools for college students (RAWSC) from 2008 onwards.

The students of the winter school are those who are passionate about astronomy or physics. Most of them want to be part of either of the two institutions. Isha Shailesh who is studying Integrated MSc in Physics and in her third year said that she is part of the group which is experimenting at Inter University Center for Astronomy and Astrophysics (IUCAA) and has visited IUCAA for the summer course too.

Bhavesh Rajpoot is a 2nd year student of BSc with specialisation in Physics at Fergusson College and he said, “Apart from academics, the best part of being shortlisted for the course are the experiments,” said Rajput.

Poorva Bhalerao is a BTech student of computer engineering from MKSSS’s Cummins College of Engineering for women said, “This course exposes us to all branches of astronomy and is a detailed study of what is in the universe. As a child I would often look up at the night sky and wonder. Now we get to study about the higher elements out there.” Kaustav Goswami from Dibrugarh University found the course to be different from the other workshops that he has attended. “With the hands on training, it is easier to understand how to apply the theories learnt. Goswami revealed that he plans to pursue a doctorate in Radio Astronomy after which he wants to be part of NCRA. Shantanu Saha who is studying second year BTech in aerospace at IIST Thiruvanthpuram said, “Lecturers are teaching us all about astronomy besides telling us about future prospects and growth of this field.” Jameer Manur, coordinator and electronic engineer (research) IUCAA said that the winter school was co-founded by Professor Joydeep Bagchi from IUCAA and Professor Bhal Chandra Joshi from NCRA in the year 2008.

“This year NCRA has been hosting the 11th winter school for a period of 10 days starting from December 14. The school provides hands on training program for the second and third year BSc and B Tech students interested in Astronomy in general and Radio Astronomy in particular,” he said. The students are exposed to a series of lectures by eminent scientists. They also get ample opportunities to carry out simple radio astronomy experiments which in turn exposes them to new developments in radio astrophysics. The students are exposed to radio astronomy techniques, analysis and they learn to interpret from simple hands-on experiments. The students of the winter school are taken on a visit to GMRT (Giant Meterwave Radio Telescope) operated by NCRA, in which they get a see how it functions and how the data processed.


“Motivational speech and interaction with eminent scientists who are pioneers in their fields also takes place. Last year Professor Govind Swaroop , Pioneer in Radio Astronomy and founder of NCRA interaction with the students of winter school. This year, Professor Jayant Narliker, founder and former director of IUCAA will be visiting the students to guide the students on their career path,” said Jameer.

Subhashis Roy, co ordinator for radio astronomy winter school from NCRA said that it is the only programme which emphasizes on hands- on experiments.

“Majority of students who attend the winter school have gone to some of the finest premier institutes to do their Ph D. The main goal is to provide a platform for training undergraduate students of science and engineering in radio astronomy techniques and instrumentation, thereby generating enough human resources for various national facilities for radio astronomy and also for enhancing Indian participation in international radio astronomy facilities,” he said.

Moreover, the galaxy is 260 light years away and:

the ring is 380,000 lightyears wide, much bigger than the galaxy itself.

I am not saying indians are not capable of achieving great heights,they certainly are.
But given the current circumstances under the BJP RSS vedic government ,we can confidently question the credibility and authenticity of this discovery.
They will soon come up with a new discovery that galaxy belongs to hindutva because there was a shiv mandir overthere. @Imran Khan

 

[Dr. Strangelove]

260 light years you got to be kidding me.

The nearest satellite galaxy of milky way large Magellanic cloud is 163,000 LY away. While the nearest spiral galaxy Andromeda is 2.5 million light years away.
He might be confusing a local star cluster with a galaxy.

Kaun si galaxy dekhli.....
The nearest galaxy to our milky way is called Andromeda and it is at 2,000,000 light years distance...

Koi aawaara bachcha type galaxy ho sakti hae.

No no, you can speak Gali. I know you and others like you will suffocate without that. Your minister also did that in Chandrayaan mission. These restrictions are for those who have any shame left.

 

[SecularNationalist]

Yes. With its two main stars, to be named Amit-1 and Yogi-1.

And discovering a vedic spacecraft operating overthere since 3000BC
And if the astronauts cover themselves in cow dung they won,t feel any gravity effects in space just like cow dung protect themselves during a nuclear bomb strike

Maybe the reporter hasn't written it correctly? That could also be the case.
