On Wednesday morning, all sort of fantasies and imaginations became REAL! For the first time, mankind could peep into the most mysterious entity of the Cosmos- THE BLACK HOLE! This remarkable effort of more than 200 astronomers and scientists all across the globe is commendable! During the live screening at Washington, that first look blew minds of thousands of astronomy enthusiasts!
LET US HAVE A LOOK AT THE 10 AMAZING FACTS about the devouring secretive black hole that has boggled with the minds of astronomers and astronomy fans for more than half a century now!
1.The blurry doughnut that forms a ring of gas and dust halo is what we see as the black hole’s disc – which feeds the monster within. This is what it looks like when you stare into it.
2.ONE CAN’T CAPTURE THE BLACK HOLE, BUT ONLY THE LIGHT NEAR IT..!!- THE POINT OF NO RETURN or the EVENT HORIZON. The event horizon is in the black area – the shadow of the black hole against the material circling it, and eventually falling in.
3.Hence, from what you can see here, you can’t be totally sure whether it’s just the accretion disc rotating, or just the black hole, or both.
4. What you are gazing upon- is approximately the size of our entire Solar system. Feeling tiny. Aren’t you?
5.No single telescope is powerful enough to image the black hole..! THE EVENT HORIZON IS NOT A TELESCOPE ITSELF, It is huge Earth sized network of telescopes that captured the first ever image of the Supermassive BLACK HOLE lurking in the heart of the one of the most massive and second brightest Elliptical galaxy- M87!
6. After years of analysing the two black holes, the event horizon did not reveal the image of Sagittarius A, a monstrous black hole that lies in our very own galaxy- Milky Way, but it gave us a picture of even huge black hole which was enormous and less obscured.
7.Surprisingly, it was harder to get the image of our own galaxy’s black hole which was in fact nearer because the "ring of flaming fire" around the black hole at the heart of the Milky Way is smaller and dimmer.
8.Over the 10 days, 200+ scientists and an array of 8 telescopes across the globe collected this magnificent data which was way too much to be sent over the internet. It was rather stored in hundreds of hard drives and was flown to the major processing centre
9. The black hole is 55-million light years away from us and approximately 3 million times the size of Earth! It is one of the heaviest black holes that we know of!
10.This revolutionary image has supported the Einstein’s theory of relativity which even he himself was sceptical about!
Indian Space Research Organisation has launched a special programme for School Children called "Young Scientist Programme" "YUva VIgyani KAryakram" from this year, in tune with the Government's vision "Jai Vigyan, Jai Anusandhan".
The Program is primarily aimed at imparting basic knowledge on Space Technology, Space Science and Space Applications to the younger ones with the intent of arousing their interest in the emerging areas of Space activities. The program is thus aimed at creating awareness amongst the youngsters who are the future building blocks of our Nation. ISRO has chalked out this programme to "Catch them young".
The programme will be of two weeks duration during summer holidays (second half of May 2019) and the schedule will include invited talks, experience sharing by the eminent scientists, facility and lab visits, exclusive sessions for discussions with experts, practical and feedback sessions.
It is proposed to select 3 students each from each State/ Union Territory to participate in this programme covering CBSE, ICSE and State syllabus.
There are a few seats left for the programme and it is proposed to select through online registration. Those who have just completed 9th standard (in the academic year 2018-19) and waiting to join 10th Std (or just joined 10th Std) will be eligible for the online registration.
The selection is based on the 8th Standard academic performance and extracurricular activities. The selection criteria is given below.
|1||Performance in the 8th Std Examination||50%|
|2||Membership of Science Club/Space Club||5%|
|3||Prize in any school based individual extracurricular activity (Elocution/Debate/Essay Writing, science quiz, computer modeling, scientific prototype model making, etc.,) at District/State/National/ International Level (The higher level will be considered for weightage)||2/4/6/10%|
|4||Winners of District/State/National/International Level sports activities (The higher level will be considered for weightage)||2/4/6/10%|
|5||Scout and Guides/NCC/NSS Member||5%|
|6||Studying in Village/Rural School (Certificate of proof to this effect to be produced from the head of the school . Criteria: The school, where the candidate is studying should be located in Panchayath Area)||20%|
Students belonging to the rural area have been given special weightage in the selection criteria. In case there is tie between the selected candidates, the younger candidates will be given priority.
A few seats are left for the programme and the interested students can register online with the link given below from 25 March 2019 (1800 hrs) to 03 April 2019 (1800 hrs). The list of the provisionally selected candidates from each state will be announced on 06 April 2019. The provisionally selected candidates will be requested to send the attested copies of the relevant certificates through E-mail. After verifying the relevant certificates the final selection list will be published on 13 April 2019.
The progamme is planned at 4 centres of ISRO during the second half of May 2019. The selected students will be accommodated in ISRO guest houses/hostels. Expenditure towards the travel of student (II AC fare by train from nearest Rly Station to the reporting centre and back), course material, lodging and boarding etc., during the entire course will be borne by ISRO. II AC fare will also be provided to one guardian/parent for drop and pick up of student from the reporting centre.
