Danielle Skinner wins NASA grant targeting graduate students

Physics Student’s Search for Precious Metals from Neutron Stars Hits the Funding Motherlode

Neutron stars collide, and a swarm of heavy elements like gold and platinum shoot out into the universe. Danielle Skinner wants to learn more about that process, and thanks to NASA, she won’t have to worry about funding that research for the next three years.

Skinner, a graduate student of associate professor John Wise in the School of Physics, is the winner of a NASA FINESST (Future Investigators in NASA Earth and Space Science and Technology) Award. Only 19 of 158 astrophysics proposals were selected for the fellowship.

“I was surprised to see that I had been selected,” says Skinner, a graduate teaching assistant. “I had to read the email a few times over for it to really sink in.”

“I was ecstatic when I first received news of Danielle’s fellowship,” Wise says. “I am very proud of her. This independent fellowship is very prestigious, and gives Danielle the freedom to explore the mysteries of the early universe.”

Through the FINESST program, NASA’s Science Mission Directorate (SMD) “solicits proposals from accredited U.S. universities and other eligible organizations for graduate student-designed and performed research projects that contribute to SMD’s science, technology and exploration goals,” according to a space agency press release.

“FINESST awards research grants with a research mentor as the principal investigator and the listed graduate student listed as the student participant. Wise, who is also a member of Georgia Tech’s Center for Relativistic Astrophysics, is listed as principal investigator (PI) and Skinner is the future investigator (FI).

“Nucleosynthesis from Neutron Star Mergers in the Early Universe” is the title of Skinner’s proposal. It will take Wise and Skinner back to the early stages of the universe through simulations. An ongoing quest in astrophysics is understanding the evolution of the periodic table, and in particular, figuring out where some of the heaviest elements, like gold and platinum, actually came from.

“We think that in the early universe, merging neutron stars could provide the right environment for these elements to form, and eventually, those heavy elements would end up in stars that we see today,” she says.

Skinner will run a series of simulations where she models neutron star mergers with varying parameters to try to find those with heavy metal abundances.

Online Public Nights: Georgia Tech Observatory Offers Live Looks, Virtual Tours of Venus and the Moon

*For those interested in learning more about astronomy, the next public night will be live-streamed on May 28 at 9:30 PM on the Georgia Tech Observatory YouTube, weather permitting. Mark the date to enjoy a guided tour to the marvels of our universe — from wherever you may find yourself in it!

On May 7, as a full moon came into focus in the night sky, several hundred computer screens lit up for a showing of the evening’s “supermoon” Flower Moon. Through a live stream on YouTube, curious observers tuned into the Georgia Tech Observatory’s first online public night, and were treated to live looks and a guided tour of Venus and Earth’s moon. 

Since the Observatory opened in 2007, public nights have traditionally been held on the roof of Howey Physics Building, where four telescopes reach deep into the night sky, and visitors of all ages gather to learn about the wonders of the universe together. But with this year’s campus closures and event cancellations due to COVID-19, spring and summer nights at the Observatory were shaping up to be rather quiet ones — until Observatory Director Jim Sowell teamed up with a colleague to quickly take the outreach program online.

The two-man crew of Sowell and telescope operator John Wallom directed Tech’s inaugural online public night at the Observatory, focusing a telescope connected to a live stream for an in-depth tour of Venus and the moon. Moving from craters to mountains to “lunar maria” — large, dark, basaltic plains on Earth’s moon, formed by ancient volcanic eruptions — Wallom controlled the telescope and handled telecommunications, while Sowell explained the topographies and histories of two of the brightest celestial objects that light up our night sky.

“I have always enjoyed showing views of celestial objects to others,” says Sowell. “It is my opportunity to give a person a peek through a window into the universe.” 

During a typical Observatory night, hundreds of curious students and visitors flock to Howey to see the wonders of space. And when Sowell shows visitors planets in person, he says their live reactions confirm his belief in the magic of studying the stars. 

“The best aspect about my job is the excitement people share when they see the cratered surface of the moon,” says Sowell. “Many often squeal! It is the celebrated joy of personal discovery and experience which is why astronomers host such events.” 

While the adjustment to an online public night prevented Sowell from seeing those reactions in person, he shared that public feedback from far-flung viewers in Florida, Tennessee, and Brazil affirmed the night as a success. 

Sowell notes that observatories across the nation carry the responsibility of making astronomy accessible to the public. He says that hosting public nights, that bring the wonders of astronomy to the Georgia Tech community and beyond, has always been a focus for the Observatory. Public nights can also foster curiosity and interest in exploring our universe at an early age. 

“I have been in love with astronomy and the night sky since I was very young,” says Sowell. “I got my first telescope when I was seven years old.”

The work of the Georgia Tech Observatory has grown and evolved over time. Several courses, research endeavors, development of the Georgia Tech Astronomy Club, and outreach to the greater Atlanta area are centered as critical facets of the Observatory’s efforts. One example of this work includes a current collaboration between several researchers from the Daniel Guggenheim School of Aerospace Engineering and several GTRI scientists and engineers, who have teamed up to use the Observatory’s telescopes to measure characteristics of earth-orbiting spacecraft. 

Sowell shares that one long-term goal is incorporating astronomy into the educational framework for younger students, with the intention of fostering an early interest in astronomy and general scientific discovery.
