Odyssey through space and time

Already at the age of 5, Jane Rigby—now Senior NASA JWST Project Scientist and one of the conveners of the first ISSI Breakthrough Workshop—got hooked by a TV show about the cosmos. Growing up in a small town, she says, makes people go search for things to do. For Jane, this was the public library of her town. In this library, she found books that fulfilled her curiosity about what’s beyond her little town, and also beyond our planet. Four decades later, Jane is presenting the first JWST images to the President of the United States, Joe Biden, at the White House.

Trials and Triumphs

Given her early fascination with space, her career path seemed quite like a straight line, but there were definitely moments that changed its direction. Overseeing submission proposals for using the world’s sharpest lenses on the universe, she acknowledges the importance to withstand academic rejection. Space scientists putting their greatest ideas out there to be evaluated is making people vulnerable to some degree. Every year there are great ideas submitted worth to fill nine years of telescope usage, Jane says. That many ideas—no matter how great they are—simply cannot be accommodated. So, great ideas must be rejected frequently.

Pioneering Diversity and Inclusion

Having attended many meetings as the only woman in the room, Jane has seen significant development towards a more gender-diverse and welcoming work environment. She says that a major factor that has changed, and contributed to continue this change, is that more scientists today are challenging bullying in the work place and advocating for change more readily. The readiness to speak up not only counteracts widespread harassment directly, but also helps to prevent it as the problem gets more widely acknowledged and understood.

A Collaborative Endeavour

Jane appreciates the ISSI workshop not only because they assembled a diverse group of researchers in the welcoming environment at ISSI, but also because it allows her and her peers to take a step back and contemplate what has been learned. The JWST telescope is about 100 times more sensitive than the best performing telescopes before, which critically also leads to much, much faster observations: „What used to take a year before, can now be done in one hour, creating new possibilities. And these new possibilities are approached with so much joy.“ Jane says enthusiastically and further elaborates that it feels like watching a firework show, where fascinating discoveries are made in all parts of the field at the moment.

At ISSI, Jane says, they brought a broad team of experts together to take a step back and have a coordinated look at all these fireworks and and find the biggest, overarching themes. She further elaborates: „The excitement of the workshop participants is palpable, and we can’t help to discuss about what’s next.“

By having a more complete view on the recent insights, it becomes clear that there are some key advances in our understanding of the first Billion years in the Universe. Surprisingly, thousands of galaxies seemed to have formed already that early on. They formed fast, converted gas into stars very efficiently, and a significant amount of these early galaxies host massive black holes. „We see a fast, organised growth of galaxies that are brighter and have appeared earlier than what we have thought“, Jane says with similarly bright eyes underscoring her excitement.

Another New Era of Discovery

As technology evolves, so does our understanding of the cosmos. From Galileo and the discovery of the Jovian planetary system—a little „solar system“ within a solar system—Jane says it is how space science uses to evolve. However, back in Galileo’s days, and even a few years back, it was unlike harder to get access to the latest data. Today, JWST data is openly available, latest one year after they have been recorded. This caused quite a surprise when Jane one day came back to the house after mowing the lawn and looked at her phone just to find the data she just collected being already used and shared by space enthusiasts online.

Sharing the Wonder of Space

Jane is all in when it comes to sharing her knowledge about our universe, such as directly with the president of the United States or in plenary lectures with American Astronomical Society. Here in Bern, Jane takes on the role as moderator of the panel discussion at the ‚ISSI Cosmic Beginnings’ event. She takes this opportunity to share the excitement of the space science community with the public and promote the humanity of the recent discoveries: „The JWST telescope is a true human endeavour, crossing geographic and other boundaries, and something inherently good.“

Pioneering an Interdisciplinary Approach to Space Commerce

The recent conference, “The Economics and Law of Space-Based Commerce,” convened here in Bern, Switzerland, brought together key stakeholders and researchers from diverse fields, including economics, law, politics, and space sciences. The event tackled pressing questions surrounding the governance framework for private actors in space commerce.

Participants delved into the applicability of current economic concepts to outer space activities and examined the complexities of international economic law in this emerging domain. From exploring the potential application of existing trade, investment, and tax laws to space-based commerce to identifying new areas for multidisciplinary research, the conference provided a platform for rich discussions and insights.

Jointly hosted by the World Trade Institute (WTI), the University of Bern, and ISSI, with support from the Swiss Institute of Comparative Law (SICL), COSPAR, and the University College Dublin (UCD), this event aimed to pave the way for future collaborations and advancements in understanding the economics and law of space commerce. Representatives from the Swiss Space Office (SSO) and the Swiss Federal Department of Foreign Affairs (EDA) also contributed to the vibrant exchange of ideas.

The Economics and Law of Space-Based Commerce (Conference hosted by WTI and ISSI | 17–18 January 2024)

This conference (17–18 January 2024) will focus on the economics and governance of commercialisation in outer space. It will look at the applicability of economic concepts, the concepts of international economic law, and the concepts of economic governance to space-based commerce.

The goal is twofold: The first goal is identifying promising areas for future research along the lines outlined above, specifically a cross-disciplinary mix of economics, law, political science, and applied natural science. The second goal is to enlist interested researchers in setting up a research and workshop agenda and loose organizational/coordinating structure (a researcher network) based on the areas identified.

The conference will be hosted jointly by the International Space Science Institute and the World Trade Institute.

“Hubble and the James Webb Space Telescope: A Tale of Two Observatories in Space” with John M. Grunsfeld, NASA Astronaut

The Hubble Space Telescope has been called the most productive scientific instrument in human history. Launched in 1990, the telescope has performed observations which have measured the age of the Universe, confirmed the existence of black holes, discovered the accelerating Universe, and amazed the general public. On Christmas day in 2021 the James Webb Space Telescope (JWST) was launched into space after decades of development. JWST was designed to extend the view of Hubble in regions of the cosmos Hubble can’t penetrate. JWST is exceeding the grand expectations of its ability to unravel the mysteries of the Universe. Join Astronaut/Astrophysicist John Grunsfeld as he takes us through the stories of Hubble and Webb.

Astronaut John M. Grunsfeld

John M. Grunsfeld is a scientist and former astronaut with extensive experience as a leader in human space exploration, space science missions, and national space policy. He has served as a NASA astronaut, the Associate Administrator for Science, and Chief Scientist at NASA Headquarters in Washington, D.C. Previously he served as the Deputy Director of the Space Telescope Science Institute in Baltimore, managing the science program for the Hubble Space Telescope and the forthcoming James Webb Space Telescope.

“The Earth, a Planet like no Other” – Online Presentation with Anny Cazenave

This presentation was recorded on November 13, 2020 (on the occasion of ISSI’s 25th anniversary).

Abstract: The Earth is the only planet of the Solar System hosting evolved life. «How to build an habitable planet ?» has led to considerable scientific literature in the recent decades and has strongly motivated research on exoplanets. All along its history the Earth has displayed specific chemical and physical properties, including a relatively stable climate that a played major role in the evolution of living organisms. In this presentation we discuss the physical particularities of planet Earth, such as gravity and magnetic fields, rotation, mantle convection and plate tectonics, volcanism and water cycle, and their impacts on climates and life, from paleo times to present. Today, Homo Sapiens polulation is approaching 8 billions, a factor 8 times larger than 2 centuries ago, and an indirect consequence of fossil energy use and associated technological innovation. However, our present-day world is facing a number of new «Grand Challenges», as summarized by the United Nations (UN) 2030 Agenda for Sustainable Development. By providing invaluable information on the Earth system and its evolution under natural and anthropogenic forcing factors, Earth observation from space has a key role to play for reaching several of the 17 Sustainable Development Goals of the UN 2030 Agenda, in particular those related to current climate change, water resources, land and marine biodiversity and food security.

Anny Cazenave received her Ph.D. in geophysics in 1975 from the University of Toulouse. Subsequently, working at the French space agency CNES, she went into space geodesy, the use of satellites to track changes in Earth’s surface, gravity field and orientation in space. She first focused on the dynamics of the oceanic crust and the mechanically strong layer of the uppermost mantle below it. Among other things, she used early space- borne radars to show that the ocean surface is not flat, but follows the topography of the ocean floor. In other early work, she addressed questions about the rotation of Venus and the origins of the Mars moons, Phobos and Deimos. Towards the end of last century, European and American space agencies launched a new series of satellite radar altimeters capable of monitoring sea level everywhere in the world oceans in more or less real time. By the early part of the 21st century, it had been determined that global sea level was rising by at least about three millimetres a year. As one of the leading scientists in the joint French/American satellite altimetry missions, TOPEX/Poseidon, Jason-1, and the Ocean Surface Topography Mission, Anny Cazenave has contributed to a greater understanding of this sea level rise and its dependence on global warming. Besides a large number of publications, Anny was lead author of the sea level sections of the Intergovernmental Panel on Climate Change’s most recent full reports, in 2007 and 2014.

Since 2013, she has been director of Earth sciences at the International Space Science Institute in Bern. In 2020, she received the prestigious Vetlesen Prize, often referred to as the Nobel Prize in geophysics, for her pioneering work in using satellite data to chart and quantify rises in the surface of the oceans, and related changes in ice sheets, landmasses and freshwater bodies.

Interview with Johannes Geiss Fellow Bruno Leibundgut

Bruno Leibundgut (European Southern Observatory (ESO), Garching, Germany) was elected as the Johannes Geiss Fellow 2019. He will give a Pro ISSI Talk on “Cosmology Today”, October 14, 18:15h CET. You can join this talk online (Zoom Webinar): https://bit.ly/2DJ74Pr  Meeting ID: 81330166057 Password: 481628. More Information about the Pro ISSI Talk >>

In the following paragraphs he answers a few questions – asked by Lorena Moreira, ISSI Earth Sciences Post Doc – about his scientific work (in pandemic times).

Lorena Moreira: How has the Johannes Geiss Fellowship contributed to your career? And why did you apply to the Fellowship?

Bruno Leibundgut: The Johannes Geiss Fellowship was a great opportunity for me to refocus some of my research and reconnect to Swiss astronomy. Most of my professional career was spent at an international organisation and an observatory. This means that I had to deal with many science administration aspects and for a while, during my time as ESO Director for Science, was contributing to the scientific direction of the organisation and managing the scientific environment. There was not much time left for research. 
The Johannes Geiss Fellowship allowed me to catch up with recent developments in my fields of supernova physics and cosmology. Being able to devote all of my time to research was a very welcome change to my current work. This was also the reason to apply for the Johannes Geiss Fellowship. It seemed to be an ideal opportunity to combine the research time it promised at a scientific institute in Switzerland. I used the time to meet several astronomers in Bern and Geneva to discuss various projects and the interaction of Swiss astronomers with ESO.

Lorena Moreira: On which projects did you work during your stay at ISSI?

Bruno Leibundgut: The original plan was to write up a paper from a Masters thesis of one of my students on SN1987A. He analysed the evolution of this nearest supernova in several centuries from a decade of HST observations and his results should be cast into a publication. My first weeks at ISSI were used to clear my ESO work backlog. I also had a couple of trips to conferences and for talks during my Johannes Geiss Fellowship. My research at ISSI focussed is on some cosmology aspects, which I wanted to explore more deeply. This also involved learning new software tools. The time at ISSI enabled me to enlarge my knowledge and read up on topics, which in my normal work life always seemed to fall to the wayside. 
The main research work in the end was on the adH0cc (accurate distances for H0 through core collapse supernovae) project. I am leading a large programme with the ESO Very Large Telescope (VLT) to carefully observe about 2 dozen individual Type II supernovae to determine their distances and then derive the local cosmic expansion rate, the Hubble constant. We acquire detailed spectroscopy and photometry of a supernova over several weeks to follow its brightness evolution and the speed with which it expands to connect these parameters into a distance measurement. Much of the data reduction processes were worked out during my time in Bern.

Lorena Moreira: What are according to you the next breakthroughs in cosmology? What do you think the future hold for your scientific career?

Bruno Leibundgut: There is a discrepancy of the value of the Hubble constant from measurements in the local and the distant universe. This ‘Hubble tension’ could, if confirmed, point to deficiencies in the currently favoured cosmological model, the Lambda Cold Dark Matter (Lambda CDM) universe. This model contains several components that at the moment lack a physical understanding, namely ‘dark energy’ in the form of Einstein’s cosmological constant Lambda and ‘dark matter’, which is inferred indirectly, but has so far not been detected as a particle. These particles would have to be fairly massive so that they can clump under gravity to form galaxies. We call this type of matter ‘cold’. The difference of the Hubble constant as calculated from the information in the distant universe, the measurements from the cosmic microwave background as determined by the ESA Planck satellite, and the direct measurement in the local universe shows that the Lambda CDM model may not be complete. Right now it is unclear, whether this is a real physical effect or just systematic problems of the Hubble constant determinations. It is important to explore as many independent methods as possible to check that we are not fooled by unknown problems in the measurements. 
Our adH0cc project contributes a new method of the local Hubble constant that is completely independent of any of the other determinations. It will take a couple of years until we have collected the necessary data and can analyse them. In the end, we should be able to check for any systematic effects we use to measure the Hubble constant. In some sense, this work arches back to the start of my scientific career, where I also tried to determine the Hubble constant – with an uncertainty that was a factor 10 higher than today’s measurements! 
I was always interested in the physics of stellar explosions and how this connects to their use as cosmological distance indicators. My research of this connection continues and I hope that I can learn about the explosion physics as much as about cosmology. There are plenty of unsolved problems in both areas. The current cosmological picture has firmed up significantly over the past two decades, but with dark energy and dark matter contains at least two parameters, which lack a physical understanding. 

Lorena Moreira: As you have recently experienced staying away from your permanent office during your visits at ISSI and during the current pandemic situation, what do you think that we can learn from these experiences to thrive scientifically?

Bruno Leibundgut: ISSI was a great place for me to focus on my research. The quiet environment allowed me to concentrate on the adH0cc project and make the necessary preparations to fully explore the data. Such quiet periods, when the hectic of the outside world is shielded, are important in a research career. I believe, they are needed to focus one’s mind. Small ’sabbatical’ stays, like my Johannes Geiss Fellowship at ISSI, are important to reflect on the research direction. The ISSI setting was especially joyful for me; I could quietly sit in my office and work for myself but was connected to the scientific environment of the institute and the University of Bern. I participated in the CSH Science and Religion Forum: “Limits of Science – Opportunities for Religion?”, which I would not have been able to do in my regular work environment, simply because there would not have been the time. The combination of ‘quiet time’ in a lively environment seems to me conducive – maybe even central – to research work. The exchange beyond the limited scientific topics to enlarge the intellectual horizons is key for good science.  
With the pandemic and increased home office the nature of meetings has changed. The many online meetings and conferences offer new opportunities, e.g. participation from different time zones and recording of presentations for asynchronous viewing. We experience an increased participation through the online format, which means that more people can attend online meetings and at a decreased cost. My experience, though, is that discussions are stifled through the online format and are much reduced. 

The future will see a combination of the different formats. Small focussed meetings to discuss specifics and with free-format discussion rounds profit from direct and extended interaction, while the general information exchange meetings should become hybrids with some physical participation and streaming/recording for a wider audience.  

 

The Johannes Geiss Fellowship (JGF) is established to attract to ISSI – for limited duration visits – international scientists of stature, who can make demonstrable contributions to the ISSI mission and increase ISSI’s stature by their presence and by doing so will honor Johannes Geiss for his founding of ISSI and his contributions to ISSI, and for his many contributions to a broad range of space science disciplines.

In 2020, Prof. Weiqing Han, University of Colorado at Boulder, USA and Prof. Sabine Schindler, University of Innsbruck, Austria have been elected as the 2020 Johannes Geiss Fellows. Read here the Interview with Weiqing Han and Sabine Schindler – Johannes Geiss Fellows 2020 >>
