1. Kathrin Altwegg:

   The first time we saw it I think we all went a little bit into denial because it was not expected to be found in a comet, molecular oxygen is very reactive. There was a lot of hydrogen around when the solar system was formed. Everybody and all models showed that molecular oxygen would react with the hydrogen and would no longer be present as molecular oxygen.

2. Charles Kilpatrick:

   Unlike its normal behavior right after it exploded, the hydrogen interaction revealed it's kind of this oddball supernova, but it's exceptional that we were able to find its progenitor star in Hubble data. In four or five years, I think we will be able to learn more about what happened.

3. Uwe Remme:

   Electricity from sources such as wind, solar and nuclear is essential for decarbonising our energy system -- but it can not do it alone, and long-distance transport and heavy industries are home to the hardest emissions to reduce, hydrogen is versatile enough to fill some of these critical gaps -- in providing vital feedstocks for the chemicals and steel industries or crucial ingredients for low-carbon fuels for planes and ships.

4. Diana Dragomir:

   TOI1231b could have a large hydrogen or hydrogen-helium atmosphere, or a denser water vapor atmosphere, each of these would point to a different origin, allowing astronomers to understand whether and how planets form differently around M dwarfs when compared to the planets around our Sun, for example.

5. Bill Murtagh:

   We're talking the energy equivalent of millions of 100-megaton hydrogen bombs exploding at the same time.
