Inside the Sky at Night<\/em><\/span><\/h2>\n\n
JAMES WEBB SPACE TELESCOPE SPECIAL <\/strong><\/em><\/h6>\n\n

As the first images from JWST come in, Mikako Matsuura <\/strong>recalls how she won not just one but two observing opportunities on the world\u2019s most anticipated telescope <\/p>\n\n

With a mirror area 64 times bigger than NASA\u2019s previous infrared space telescope and instruments up to 100 times more sensitive, the James Webb Space Telescope (JWST) will allow us to take deeper and sharper images of astronomical objects than ever before. <\/p>\n\n

Although JWST is a NASA-led mission with involvement from the European and Canadian space agencies, astronomers from any country can apply for observing time. When the call for proposals went out in 2018, I decided to request observations of Supernova 1987A. It\u2019s the closest supernova explosion in the last 400 years, located 170,000 lightyears away from Earth. We\u2019ve been able to see the fast shock waves from the supernova, travelling at 1,000km\/s, as they expand and destroy the surrounding material. <\/p>\n\n

Writing an observing proposal is time-consuming. It takes up to two weeks, requiring detailed simulations of how much time is needed. But just as I finished writing the proposal and went to click the submit button, an e-mail from NASA arrived announcing the launch was delayed. How disappointing! JWST is a $10bn space mission, so of course it\u2019s better to be safe than sorry. But still, it was disheartening. <\/p>\n\n

NASA reopened proposals two years later. When I looked back at my work, I realised it lacked a punchline: \u201cWhy do we need the JWST for this observation?\u201d It\u2019s a key point that should be included in any observing proposals, but it was missing. I realised JWST will be able to capture how blast shock waves break up dust, which we couldn\u2019t see before. <\/p>\n\n

Made it, with time to spare <\/strong><\/h4>\n\n

Then, three days before the deadline, when everything was sorted, I realised something was wrong in my exposure time simulation. I started panicking, but it\u2019s always helpful to have collaborators. My colleagues Tea Temim and Martha Boyer from the Space Telescope Science Institute redid the simulations from scratch and we were able to submit on time. <\/p>\n\n

Back in 2018, I\u2019d also wanted to observe planetary nebula NGC 6302, but it would have been far too demanding to write two proposals. However, as I\u2019d done most of the work for the Supernova 1987A submission back in 2018, I was able to write a new proposal for NGC 6302 in 2020.<\/span><\/p>\n\n

It is always good to share ideas and get constructive criticism, and when I did, Rens Waters from Groningen and Eric Lagadec from Nice said, \u201cIt\u2018s a good idea, but there are too many details\u201d. Sometimes if you are in your own world, you don\u2019t really see your own faults: you lose the bigger picture. <\/span>Rens re-wrote the first key introduction paragraph, guiding the scientific case, and so the second proposal was submitted.<\/span><\/p>\n\n

Another six months passed. It was April 2021, a sunny day just before Easter. My husband and I took an extra day off and went for a drive when suddenly my phone notified me the JWST selection results were out. I was so scared to open the emails, not knowing if they would say \u201cCongratulations!\u201d or \u201cWe\u2019re very sorry\u201d. <\/p>\n\n

After I came back home, I took a breath and opened them. Both <\/em>were accepted. Unbelievable! At the same time, the responsibility to make these observing programs successful now fell on my shoulders. And now, as the data arrives, it\u2019s time for the next round of challenges to begin.<\/span><\/p>\n\n

THE SKY AT NIGHT WANTS YOUR QUESTIONS <\/span><\/h4>\n\n

As part of the British Science Festival 2022, The Sky at Night <\/em>is recording a special programme on 14 September, when the presenters and special guests will be answering questions from viewers. If you have a question \u2013 on anything from space travel and technology to astronomy and astrophysics \u2013 the programme team want to hear from you at: skyatnightqt@bbc.co.uk <\/a><\/strong><\/p>\n\n

Looking back: The Sky at Night<\/span><\/h4>\n\n\n\n

19 September 1957 <\/h4>\n\n\n\n

On 19 September 1957\u2019s episode of The <\/em>Sky <\/em>at <\/em>Night, <\/em>Patrick Moore was joined on the show by a special guest: 14-year-old astronomer Clive Hare. On 3 August, Hare had been one of the first people to observe a new comet streaking across the sky in the constellation of Gemini. Being a member of the British Astronomical Association, Hare knew to report his findings, noting that the comet was of equal brightness to nearby Pollux (mag +1.5) and around 2\u00b0 long.<\/span><\/p>\n\n\n\n

As the BAA raced to release a report, it soon became clear that astronomers all over the world were also making the same discovery. The first sighting was traced back to Japanese astronomer S Kuragano on 29 July, but several other astronomers also spotted the comet. In the end, naming rights went to the first report to reach the International Astronomical Union, which was from Czech astronomer Anoton\u00edn Mrkos.<\/span><\/p>\n\n\n\n

Now the comet is known as Comet C\/1957 P1 Mrkos. It would eventually reach a brightness of mag. +1.0 on 4 August and stretched out across 5\u00b0 of sky at its longest. After that, the comet slowly faded, passing through the constellation of Ursa Major to Coma Berenices, and was eventually lost from view in Virgo at the end of September. <\/p>\n\n\n\n

Hare\u2019s appearance on the show was part of Patrick\u2019s lifelong belief that anyone could be an astronomer, regardless of age, and his observation remains a prime example of the major role amateur astronomers play in the world of astronomical discovery. <\/p>\n<\/div><\/section>\n\n
