NASA’s Webb Reveals Distorted Galaxy Forming Cosmic Question Mark

It’s 7 billion years ago, and the universe’s heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers using NASA’s James Webb Space Telescope have found clues in the form of a cosmic question mark, the result of a rare alignment across light-years of space.

“We know of only three or four occurrences of similar gravitational lens configurations in the observable universe, which makes this find exciting, as it demonstrates the power of Webb and suggests maybe now we will find more of these,” said astronomer Guillaume Desprez of Saint Mary’s University in Halifax, Nova Scotia, a member of the team presenting the Webb results.

While this region has been observed previously with NASA’s Hubble Space Telescope, the dusty red galaxy that forms the intriguing question-mark shape only came into view with Webb. This is a result of the wavelengths of light that Hubble detects getting trapped in cosmic dust, while longer wavelengths of infrared light are able to pass through and be detected by Webb’s instruments.

Astronomers used both telescopes to observe the galaxy cluster MACS-J0417.5-1154, which acts like a magnifying glass because the cluster is so massive it warps the fabric of space-time. This allows astronomers to see enhanced detail in much more distant galaxies behind the cluster. However, the same gravitational effects that magnify the galaxies also cause distortion, resulting in galaxies that appear smeared across the sky in arcs and even appear multiple times. These optical illusions in space are called gravitational lensing.

The red galaxy revealed by Webb, along with a spiral galaxy it is interacting with that was previously detected by Hubble, are being magnified and distorted in an unusual way, which requires a particular, rare alignment between the distant galaxies, the lens, and the observer — something astronomers call a hyperbolic umbilic gravitational lens. This accounts for the five images of the galaxy pair seen in Webb’s image, four of which trace the top of the question mark. The dot of the question mark is an unrelated galaxy that happens to be in the right place and space-time, from our perspective.

In addition to producing a case study of the Webb NIRISS (Near-Infrared Imager and Slitless Spectrograph) instrument’s ability to detect star formation locations within a galaxy billions of light-years away, the research team also couldn’t resist highlighting the question mark shape. “This is just cool looking. Amazing images like this are why I got into astronomy when I was young,” said astronomer Marcin Sawicki of Saint Mary’s University, one of the lead researchers on the team. 

“Knowing when, where, and how star formation occurs within galaxies is crucial to understanding how galaxies have evolved over the history of the universe,” said astronomer Vicente Estrada-Carpenter of Saint Mary’s University, who used both Hubble’s ultraviolet and Webb’s infrared data to show where new stars are forming in the galaxies. The results show that star formation is widespread in both. The spectral data also confirmed that the newfound dusty galaxy is located at the same distance as the face-on spiral galaxy, and they are likely beginning to interact.

“Both galaxies in the Question Mark Pair show active star formation in several compact regions, likely a result of gas from the two galaxies colliding,” said Estrada-Carpenter. “However, neither galaxy’s shape appears too disrupted, so we are probably seeing the beginning of their interaction with each other.”

“These galaxies, seen billions of years ago when star formation was at its peak, are similar to the mass that the Milky Way galaxy would have been at that time. Webb is allowing us to study what the teenage years of our own galaxy would have been like,” said Sawicki.

The Webb images and spectra in this research came from the Canadian NIRISS Unbiased Cluster Survey (CANUCS). The research paper is published in the Monthly Notices of the Royal Astronomical Society.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Space Station AMS-02 Instrument Works on the Mystery of Dark Matter

Visible matter in the form of stars and planets adds up to about five percent of the total known mass of the Universe. The rest is either dark matter, antimatter, or dark energy. The exact nature of these substances is unknown, but the International Space Station’s Alpha-Magnetic Spectrometer or AMS-02 is helping to solve the mystery.

AMS-02 collects data on charged particles from cosmic ray events, which helps scientists understand the origin of those rays and could ultimately reveal whether dark matter and antimatter exist.

To date, the instrument has collected data on about 573 events per second on average – just over 18 billion per year. This high volume of data enables highly precise statistical analyses, and multiple groups of researchers independently process the raw data to ensure accurate results.

Gator Speaks

NASA’s Stennis Space Center keeps writing new history, and the front office announcement in August delights this ‘ol Gator!

The news delights me because the south Mississippi NASA center will continue to be in good hands with Christine Powell serving as the new deputy director. And talk about perfect timing – announcement of the selection came just a few weeks before the celebration of Women’s Equality Day on Aug. 26.

In her new role, Powell now is responsible, along with NASA Stennis Director John Bailey, for coordinating all the rocket propulsion test capabilities onsite, along with managing the overall NASA center.

As the nation’s largest – and premier – propulsion test site, NASA Stennis supports test operations for both government and commercial aerospace companies. Powell’s depth of knowledge positions her perfectly for this new challenge.

Her record shows that she knows the ins-and-outs of NASA Stennis and is very-well versed on propulsion testing. Her career is also a testament to NASA developing its skilled workforce. Powell started as an intern at NASA Stennis in 1991. Following the internship, she worked as an instrumentation engineer and systems integration engineer before moving into leadership positions in 2004.

All in all, Powell illustrates perfectly the important role women play at NASA Stennis – in positions and roles all across the center. Women are a vital part of the NASA Stennis team, contributing to every area of the center’s work and mission.

NASA Stennis’ aim in the future is to operate as a multi-user propulsion testing enterprise that accelerates the development of aerospace systems and services by government and industry.

This Gator has witnessed many successful endeavors at NASA Stennis, and I am confident that Powell’s new role will have her adding value to this endeavor.

Just as the focus was on women’s equality last month, September provides a time to celebrate the hard work of all with Labor Day on the first Monday of the month. As we move forward, the newest deputy director’s journey at NASA Stennis proves that work is not merely a means to an end, but also a journey to realize one’s full potential.

Key Moments Lead to Fulfilling NASA Stennis Career

Joseph Ladner’s experiences working at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, motivate him to “pay it forward” so more people can be a part of something great.

“It is exciting to be at a place like NASA Stennis that continues to reinvent itself to stay relevant,” Ladner said. “You can do just about anything you can imagine with a workforce committed to its success.”

The Gulfport, Mississippi, resident is the lead budget analyst in the NASA Stennis Office of the Chief Financial Officer. His team manages budgets that fund the nation’s premier propulsion test site.

Ladner can point to three pivotal moments propelling him to a career with NASA. The first came by attending ASTRO CAMP at NASA Stennis every summer as a child. The thrilling experiences of launching paper rockets and conducting science experiments left him with the question, “How do I get to work there?”

The answer came into focus years later. Much like launching paper rockets, Ladner’s career started at ground level before reaching higher heights.

He started on the lowest end of the General Schedule pay scale as a GS-1 clerk for the Naval Oceanographic Office, located at NASA Stennis, while attending Mississippi Gulf Coast Community College.

A second pivotal moment also came during this time. The Saucier, Mississippi, native credits mentor Pamela Stenum for putting him on a career path in procurement so he could use the math and analytical skills that came natural to him.

The clerk role, expected to be only for one semester, continued through Ladner’s studies at The University of Southern Mississippi, where he earned a bachelor’s degree in Business Administration.

“I literally came in from the bottom, and someone saw potential in me,” Ladner said. “She realized I was a hard worker and that I cared about the product I was putting out.”

The third, and most profound, moment leading Ladner to a NASA career happened when the space shuttle Columbia orbiter suffered a catastrophic failure during return to Earth.

“I will never forget standing in the crowd that morning waiting for the launch of Columbia (in 2003) and hearing the commander over the loudspeakers thank everyone for the efforts to get them to this point and saying farewell to his family,” Ladner said. “No one knew it would ultimately be the crew’s last farewell. That tragic incident left me with a greater sense that there are many opportunities, but life is short. That thought and NASA’s return to flight mission left me with a desire to be part of NASA.”

Ladner started his career with the agency two years later and has worked inspired ever since. His role as lead budget analyst contributes to the Artemis campaign that will establish the foundation for long-term scientific exploration of the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

His job currently involves navigating challenges of increased costs and reduced budgets. From Ladner’s perspective, the challenges present opportunities for innovation and new ideas. 

“Knowing my work is part of a greater cause impacting the Artemis Generation that could make a difference to society is the best thing about working at NASA Stennis,” Ladner said. “There is some awe and wonder about working at NASA, so it is neat to say you are a part of that.”

Research Plane Dons New Colors for NASA Hybrid Electric Flight Tests 

Parked under the lights inside a hangar in Seattle, a hybrid electric research aircraft from electric motor manufacturer magniX showed off a new look symbolizing its journey toward helping NASA make sustainable aviation a reality.  

During a special unveiling ceremony hosted by magniX on Aug. 22, leaders from the company and NASA revealed the aircraft, with its new livery, to the public for the first time at King County International Airport, commonly known as Boeing Field.  

The aircraft is a De Havilland Dash 7 that was formerly used for carrying cargo. Working under NASA’s Electrified Powertrain Flight Demonstration (EPFD) project, magniX will modify it to serve as a testbed for hybrid electric aircraft propulsion research.    

The company’s goal under EPFD is to demonstrate potential fuel savings and performance boosts with a hybrid electric system for regional aircraft carrying up to 50 passengers. These efforts will help reduce environmental impacts from aviation by lowering greenhouse gas emissions. 

This livery recognizes the collaborative effort focused on proving that hybrid electric flight for commercial aircraft is feasible. 

“We are a research organization that continues to advance aviation, solve the problems of flight, and lead the community into the future,” said Robert A. Pearce, associate administrator for NASA’s Aeronautics Research Mission Directorate. “Through our EPFD project, we’re taking big steps in partnership to make sure electric aviation is part of the future of commercial flight.” 

Collaborative Effort   

NASA is collaborating with industry to modify existing planes with new electrified aircraft propulsion systems. These aircraft testbeds will help demonstrate the benefits of hybrid electric propulsion systems in reducing fuel burn and emissions for future commercial aircraft, part of NASA’s broader mission to make air travel more sustainable.  

“EPFD is about showing how regional-scale aircraft, through ground and flight tests, can be made more sustainable through electric technology that is available right now,” said Ben Loxton, vice president for magniX’s work on the EPFD project.  

Thus far, magniX has focused on developing a battery-powered engine and testing it on the ground to make sure it will be safe for work in the air. The company will now begin transitioning over to a new phase of the project — transforming the Dash 7 into a hybrid electric research vehicle.  

“With the recent completion of our preliminary design review and baseline flight tests, this marks a transition to the next phase, and the most exciting phase of the project: the modification of this Dash 7 with our magniX electric powertrain,” Loxton said.  

To make this possible, magniX is working with their airframe integrator AeroTEC to help modify and prepare the aircraft for flight tests that will take place out of Moses Lake, Washington. Air Tindi, which supplied the aircraft to magniX for this project, will help with maintenance and support of the aircraft during the testing phases.  

Creating a Hybrid Electric Aircraft   

A typical hybrid electric propulsion system combines different sources of energy, such as fuel and electricity, to power an aircraft. For magniX’s demonstration, the modified Dash 7 will feature two electric engines fed by battery packs stored in the cabin, and two gas-powered turboprops.  

The work will begin with replacing one of the aircraft’s outer turboprop engines with a new, magni650-kilowatt electric engine – the base of its hybrid electric system. After testing those modifications, magniX will swap out the remaining outer turboprop engine for an additional electric one. 

Earlier this year, magniX and NASA marked the milestone completion of successfully testing the battery-powered engine at simulated altitude. Engineers at magniX are continuing ground tests of the aircraft’s electrified systems and components at NASA’s Electric Aircraft Testbed (NEAT) facility in Sandusky, Ohio.  

By rigorously testing these new technologies under simulated flight conditions, such as high altitudes and extreme temperatures, researchers can ensure each component operates safely before taking to the skies. 

The collaboration between EPFD, NASA, GE Aerospace, and magniX works to advance hybrid electric aircraft propulsion technologies for next-generation commercial aircraft in the mid-2030 timeframe. NASA is working with these companies to conduct two flight demonstrations showcasing different approaches to hybrid electric system design. 

Researchers will use data gathered from ground and flight tests to identify and reduce certification gaps, as well as inform the development of new standards and regulations for future electrified aircraft. 

“We at NASA are excited about EPFD’s potential to make aviation more sustainable,” Pearce said. “Hybrid electric propulsion on a megawatt scale accelerates U.S. progress toward its goal of net-zero greenhouse gas emissions by 2050, benefitting all who rely on air transportation every day.”
