NASA’s Roman Telescope Will Observe Thousands of Newfound Cosmic Voids
Lee esta nota de prensa en español aquí.
Our universe is filled with galaxies, in all directions as far as our instruments can see. Some researchers estimate that there are as many as two trillion galaxies in the observable universe. At first glance, these galaxies might appear to be randomly scattered across space, but they’re not. Careful mapping has shown that they are distributed across the surfaces of giant cosmic “bubbles” up to several hundred million light-years across. Inside these bubbles, few galaxies are found, so those regions are called cosmic voids. NASA’s Nancy Grace Roman Space Telescope will allow us to measure these voids with new precision, which can tell us about the history of the universe’s expansion.

Cosmic RecipeThe cosmos is made of three key components: normal matter, dark matter, and dark energy. The gravity of normal and dark matter tries to slow the expansion of the universe, while dark energy opposes gravity to speed up the universe’s expansion. The nature of both dark matter and dark energy are currently unknown. Scientists are trying to understand them by studying their effects on things we can observe, such as the distribution of galaxies across space.
“Since they’re relatively empty of matter, voids are regions of space that are dominated by dark energy. By studying voids, we should be able to put powerful constraints on the nature of dark energy,” said co-author Alice Pisani of CNRS (the French National Centre for Scientific Research) in France and Princeton University in New Jersey.
To determine how Roman might study voids, the researchers considered one potential design of the Roman High-Latitude Wide-Area Survey, one of three core community surveys that Roman will conduct. The High-Latitude Wide-Area Survey will look away from the plane of our galaxy (hence the term high latitude in galactic coordinates). The team found that this survey should be able to detect and measure tens of thousands of cosmic voids, some as small as just 20 million light-years across. Such large numbers of voids will allow scientists to use statistical methods to determine how their observed shapes are influenced by the key components of the universe.
To determine the actual, 3D shapes of the voids, astronomers will use two types of data from Roman — the positions of galaxies in the sky and their cosmological redshift, the latter of which is determined using spectroscopic data. To convert redshift to a physical distance, astronomers make assumptions about the components of the universe, including the strength of dark energy and how it might have evolved over time.
Pisani compared it to trying to infer a cake recipe (i.e., the universe’s makeup) from the final dessert served to you. “You try to put in the right ingredients — the right amount of matter, the right amount of dark energy — and then you check whether your cake looks as it should. If it doesn’t, that means you put in the wrong ingredients.”
In this case, the appearance of the “cake” is the shape found by statistically stacking all of the voids detected by Roman on top of each other. On average, voids are expected to have a spherical shape because there is no “preferred” location or direction in the universe (i.e., the universe is both homogeneous and isotropic on large scales). This means that, if the stacking is done correctly, the resulting shape will be perfectly round (or spherically symmetric). If not, then you have to adjust your cosmic recipe.
Power of RomanThe researchers emphasized that to study cosmic voids in large numbers, an observatory must be able to probe a large volume of the universe, because the voids themselves can be tens or hundreds of millions of light-years across. The spectroscopic data necessary to study voids will come from a portion of the Roman High-Latitude Wide-Area Survey that will cover on the order of 2,400 square degrees of the sky, or 12,000 full moons. It will also be able to see fainter and more distant objects, yielding a greater density of galaxies than complementary missions like ESA’s (European Space Agency’s) Euclid.
“Voids are defined by the fact that they contain so few galaxies. So to detect voids, you have to be able to observe galaxies that are quite sparse and faint. With Roman, we can better look at the galaxies that populate voids, which ultimately will give us greater understanding of the cosmological parameters like dark energy that are sculpting voids,” said co-author Giulia Degni of Roma Tre University and INFN (the National Institute of Nuclear Physics) in Rome.
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory in Southern California; Caltech/IPAC in Pasadena, California; the Space Telescope Science Institute in Baltimore; and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc. in Boulder, Colorado; L3Harris Technologies in Melbourne, Florida; and Teledyne Scientific & Imaging in Thousand Oaks, California.

Gaia finds hints of planets in baby star systems
Ever wondered how planetary systems like our own Solar System form? Thanks to the European Space Agency’s Gaia space telescope, we're getting a unique peek behind the cosmic curtain into these dusty environments.
In this collage, we see the images of 31 baby star systems. Click on the white dots next to each system to find out more about them. The bar on the top right shows the scale of the image in Astronomical Units (AU).
The collage also shows our own Solar System for reference on the bottom right, as it is predicted to have looked at an age of 1 million years, with the Sun at its centre (not visible).
All of the systems are centred around very young stars that have recently collapsed from vast clouds of gas and dust.
After the clouds collapsed under their own gravity, they spun faster and flattened into discs with hot, dense centres. These centres became the stars, sometimes multiple stars were formed. The discs around them are called protoplanetary discs.
The 31 baby systems are shown here in orange-purple, as seen by the Atacama Large Millimeter Array (ALMA) ground-based telescope.
Astronomers expect the remaining material in protoplanetary discs to clump together to form planets, but until now it’s been very difficult to spot them because of all the dust and gas present in discs. To date, very few planets have been detected around forming stars.
Enter Gaia.
In 31 out of 98 young star systems, Gaia has detected subtle motions that suggest the presence of unseen companions. For seven of these systems, the observed motions are consistent with objects of planetary mass. In eight systems, the data best match the presence of brown dwarfs – objects larger than planets but smaller than stars. The remaining sixteen systems likely have additional stars around.
Gaia’s predicted locations of these companions in the systems are shown in cyan. In the reference image of our baby Solar System, Jupiter’s orbit is also shown in cyan.
Gaia discovered the companions in the baby star systems thanks to its unique ability to sense the gravitational tug or ‘wobble’ a planet or companion induces on a star. This technique had already been used to find companions around older stars. But now, for the first time, a team of astronomers led by Miguel Vioque of the European Southern Observatory, Germany, has used this Gaia technique to find planets and companions around stars that are still forming.
The all-sky, large-scale nature of the Gaia survey enabled the team to study hundreds of forming stars and identify companions across large samples for the first time. This in contrast to costly ground-based searches that can only target a few stars at a time.
This ability of Gaia is revolutionising the field of star and planet formation. The companions that the telescope has already found, can now be followed up by telescopes like the NASA/ESA/CSA James Webb Space telescope that can study the inner discs of the baby systems in more detail.
With Gaia’s upcoming fourth data release, many more hidden planets are expected to be uncovered.
This new finding has been described in ‘Astrometric view of companions in the inner dust cavities of protoplanetary disks’ by M. Vioque et al., accepted for publication in Astronomy & Astrophysics.

The Radio Signal That Predicts Aurora Storms
Scientists have discovered a crucial clue to understanding one of nature's most spectacular light shows, the aurora. Research from the University of Southampton reveals that just before these magnetospheric substorms erupt, a distinct pattern of low frequency radio waves appears above the aurora, radio emissions that surge in strength precisely as mysterious "auroral beads" transform into full storms. This radio signature, detected by spacecraft and ground observatories across multiple events, provides the first direct evidence of the physical processes triggering these dramatic celestial displays, and may explain similar phenomena occurring in the magnetospheres of Jupiter and Saturn.
A New Laboratory Explores How Planets Begin
Scientists at Southwest Research Institute have opened a new laboratory dedicated to answering one of astronomy's most fundamental questions, where do planets come from? The Nebular Origins of the Universe Research (NOUR) Laboratory will recreate the extreme conditions found in interstellar clouds, vast regions of ice, gas, and dust that existed before our Solar System formed to trace how these primordial materials ultimately evolved into the worlds we see today. By simulating the chemistry of pre-planetary environments in specialised vacuum chambers, researchers aim to understand how the building blocks of life, including the components of DNA and RNA, formed in the darkness of space billions of years ago.
2.8 Days to Disaster - Why We Are Running Out of Time in Low Earth Orbit
A “House of Cards” is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable. It’s also the term Sarah Thiele, originally a PhD student at the University of British Columbia, and now at Princeton, and her co-authors used to describe our current satellite mega-constellation system in a new paper available in pre-print on arXiv.

Unexpected Trajectory: Erin Sholl’s Path to Human Spaceflight Safety
Career paths are rarely a straight line and often include some unexpected curves. That is certainly true for Erin Sholl, deputy chief of the Space Transportation Systems Division within the Safety and Mission Assurance Directorate at NASA’s Johnson Space Center in Houston. From struggling with multiplication tables in elementary school to supporting the International Space Station from the Mission Control Center, her journey has been full of twists and turns.

Despite her early difficulties in math and science, Sholl eventually grew to love and excel in both subjects. She planned to study chemical engineering in college – inspired by a love of chemistry and a favorite high school teacher – but discovered a greater affinity for physics once she arrived at Pennsylvania State University. She switched her major to aerospace engineering and soon met a classmate who had interned at Johnson. After that, Sholl declared, “The dream was born!”
Her first position at Johnson was as a trajectory operations officer for the Flight Operations Directorate. She spent six years supporting the space station on console in the Mission Control Center, describing the experience as “something out of the movies.” When Sholl went looking for a new challenge, she landed in the Safety and Mission Assurance Directorate.

“I was drawn to the Operations and Visiting Vehicles Branch because it had many similar aspects to my previous position – real-time operations and visiting vehicles,” she said. “I worked various roles over the next 12 years, gradually taking on more responsibility, and eventually becoming a group lead, then branch chief.” Sholl also served as acting deputy chief for the Space Habitation Systems Division, which oversees the Operations and Visiting Vehicles Branch. Her performance drew the attention of the Space Transportation Systems Division’s chief. “He asked me to come be his deputy, and that is where I still am today!”
The Space Transportation Systems Division provides system safety, reliability, and risk analysis for human spaceflight programs. The division works with the different program offices to reduce risk through technical assessments and guidance on Safety and Mission Assurance requirements throughout program and project lifecycles.
Sholl works closely with the division chief to support strategic planning, budgeting, and operations. “A key part of my role is connecting with people – both inside and outside the division – to ensure smooth communication and representation of the team’s needs,” she said. She leverages her relationship-building and strategic thinking skills to lead initiatives that advance the division’s and the directorate’s goals and to mentor employees.

Sholl believes strongly in the power of mentorship. “Having various mentors, both formal and informal, has been so important throughout my career,” she said. “Listening to what these people were saying about my strengths led me to a path I’d never considered because I hadn’t seen those things in myself.” Being a mentor and advocate for team members is one of Sholl’s favorite parts of the leadership positions she has held, particularly as branch chief. “I really felt like I could connect with my people and advocate for them in a way that felt meaningful,” she said.
She encourages young professionals to seek out mentors or opportunities to shadow colleagues in different roles. “Relationships are the key to everything,” she said. “The more people you meet and the more you learn about different paths in space exploration, the better off you will be in your career.”

Sholl noted that professional relationships can be bolstered by activities outside of the office. She played a key role in establishing and growing JSC Parenting, a virtual community of about 600 employees who share information and support each other on issues related to caregiving, schooling, and balancing work with family life. “My leadership within the community enhances my professional leadership and positively impacts my colleagues,” she said.
Sholl also emphasized the importance of being open to trying new things, even if an opportunity seems to diverge from your expected career path. “I volunteer for everything because I am always eager to learn more and find out what else I might be good at and how else I can serve my team,” she said. “I think it’s easy to feel intimidated hearing about other people’s career paths, because they often sound so perfectly planned and successful. You rarely hear about the pivots, setbacks, or decisions made for personal reasons.”
The reality, she added, is more complex. “I tried for many roles I didn’t get, and it took a lot of trial and error to find my path to a career I really love.”

Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it is vastly more potent at trapping heat, which makes rapid cuts essential for slowing warming in the short term. The same satellite technology that has transformed methane monitoring in the oil and gas sector is now being turned towards another major source – landfill sites.
A Golden Era of Solar Discovery
Scientists have achieved an unprecedented view of the Sun by coordinating observations between two of the most powerful solar instruments ever built. For the first time, observations from the Inouye Solar Telescope in Hawaii and the European Space Agency's Solar Orbiter spacecraft have captured the same solar region simultaneously from different vantage points. This created a stereoscopic view that reveals intricate details of tiny "campfire" features scattered across the Sun's surface. These fleeting brightening, though individually small, occur in such vast numbers that they may collectively shape how the Sun's outer atmosphere is heated and how plasma erupts into space.
