Now that NASA’s James Webb Space Telescope’s first images and data are out, you might be wondering: What comes next?
The observatory has a packed schedule of science programs looking at all kinds of cosmic phenomena, like planets, stars, galaxies, black holes, and more. Webb will revolutionize our understanding of the universe — but first, researchers need time to analyze data and make sure that they understand what they’re seeing. Here are four things to know about Webb’s next steps:
News releases on results will be coming, too, once they have been reviewed. You may have seen scientists on social media posting their preliminary findings from Webb data. But before NASA publicizes results in news materials, we wait for the findings to be peer-reviewed — meaning, the science community has assessed the results. Science is a collaborative process of asking questions, testing out ideas, discussing with colleagues, and doing it all over. The peer-review process generally happens when researchers submit their findings to a journal or conference. It may take a little while, but it’s worth it.

The transport sector currently accounts for a quarter of energy-related carbon emissions globally. It also ranks among the fastest growing sources of such emissions. Economic development is associated with higher mobility and associated emissions, as households progress from mainly walking to relying on public transportation services, to acquiring their own two-wheel and, eventually four-wheel vehicles.
Little is known about the demand patterns for transportation services in developing countries and how these can be expected to shape emission trajectories over time. To design effective policies for the fight against climate change, it is important to understand the determinants and distribution of transport expenditures within developing countries, as well as the estimated impacts on CO2 emissions of increasing incomes.
