A new project provides special 3D “experiences” on Instagram using data from NASA’s Chandra X-ray Observatory and other telescopes through augmented reality (AR), allowing users to travel virtually through objects in space. These new experiences of astronomical objects – including the debris fields of exploded stars – are being released to help celebrate the 25th anniversary of operations from Chandra, NASA’s flagship X-ray telescope.
In recent years, Instagram experiences (previously referred to as filters) of NASA mission control, the International Space Station, and the Perseverance Rover on Mars have allowed participants to virtually explore what NASA does. This new set of Chandra Instagram filters joins this space-themed collection.
These four images showcase the 2D captured views of the cosmic objects included in the new augmented reality 3D release.

Arcand “We are excited to bring data from the universe down to earth in this way,” said Kimberly Arcand, visualization and emerging technology scientist at the Chandra X-ray Center. “By enabling people to access cosmic data on their phones and through AR, it brings Chandra’s amazing discoveries literally right to your fingertips.”
The new Instagram experiences are created from 3D models based on data collected by Chandra and other telescopes along with mathematical models. Traditionally, it has been very difficult to gather 3D data of objects in our galaxy due to their two-dimensional projection on the sky. New instruments and techniques, however, have helped allowed astronomers in recent years to construct more data-driven models of what these distant objects look like in three dimensions.
These advancements in astronomy have paralleled the explosion of opportunities in virtual, extended, and augmented reality. Such technologies provide virtual digital experiences, which now extend beyond Earth and into the cosmos. This new set of Chandra Instagram experiences was made possible by a collaboration including NASA, the Smithsonian Institution, and students and researchers at Brown University.
These Instagram experiences also include data sonifications of the celestial objects. Sonification is the process of translating data into sounds and notes so users can hear representations of the data, an accessibility project the Chandra team has led for the past four years.
“These Chandra Instagram experiences are another way to share these cosmic data with the public,” said Arcand. “We are hoping this helps reach new audiences, especially those who like to get their information through social media.”
The objects in the new Chandra Instagram experience collection include the Tycho supernova remnant, the Vela Pulsar, the Helix Nebula, the Cat’s Eye Nebula, and the Chandra spacecraft. The 3D models of the first three objects were done in conjunction with Sal Orlando, an astrophysicist at Italy’s National Institute for Astrophysics (INAF) in Palmero. The Cat’s Eye Nebula was created with data from Ryan Clairmont, physics researcher and undergraduate at Stanford University. Arcand worked with Brown’s Tom Sgouros and his team, research assistant Alexander Dupuis and undergraduate Healey Koch, on the Chandra Instagram filters.
The experiences include text that explains what users are looking at. The effects are free and available on Instagram on mobile devices for at least six months, and some will remain viewable in perpetuity on the Smithsonian’s Voyager 3D website.
“There is a lot of rich and beautiful data associated with these models that Healey and I looked to bring in, which we did by creating the textures on the models as well as programming visual effects for displaying them in AR,” said Dupuis. Add links?

The use of non-model organisms in medical research is an expanding field that has already made a significant impact on human health. Insights gleaned from the study of unique mammalian traits are being used to develop novel therapeutic agents. The remarkable phenotype of mammalian hibernation confers unique physiologic and metabolic benefits that are being actively investigated for potential human health applications on Earth. These benefits also hold promise for mitigating many of the physical and mental health risks of space travel. The essential feature of hibernation is an energy-conserving state called torpor, which involves an active and often deep reduction in metabolic rate from baseline homeostasis. Additional potential benefits include the preservation of muscle and bone despite prolonged immobilization and protection against radiation injury. Despite this remarkable potential, the space-based infrastructure needed to study torpor in laboratory rodents does not currently exist, and hibernation in microgravity has never been studied. This is a critical gap in our understanding of hibernation and its potential applications for human spaceflight. We propose to remedy this situation through the design and implementation of STASH, a novel microgravity hibernation laboratory for use aboard the ISS. Some unique and necessary design features include the ability to maintain STASH at temperatures as low as 4°C, adjustable recirculation of animal chamber air enabling the measurement of metabolism via oxygen consumption, and measurement of real-time total ventilation, body temperature, and heart rate. The STASH unit will also feature animal chamber sizes that will accommodate the expected variety of future hibernating and non-hibernating species, boosting its applicability to a variety of studies on the ISS by enabling real-time physiological measurements. The STASH unit is being designed in collaboration with BioServe Space Technologies to be integrated into the Space Automated Biological Laboratory (SABL) unit. This will allow for the achievable and practical application of this research to advance our understanding of both hibernation and mammalian physiology in space. The short-term goals of the STASH project are novel investigations into the basic science of hibernation in a microgravity environment, laying the foundation for application of its potential benefits to human health. These include determining whether hibernation provides the expected protection against bone and muscle loss. The medium-term goals of the project begin developing translational applications of hibernation research. These include using STASH both for testing bioactive molecules that mimic the transcriptional signatures of hibernation and for evaluating methods of inducing synthetic torpor for their ability to provide similar protection. As a long-term goal, during a crewed mission to Mars, human synthetic torpor could act as a relevant countermeasure that would change everything for space exploration, mitigating or eliminating every hazard included in NASA’s RIDGE acronym for the hazards of space travel: Space Radiation, Isolation and Confinement, Distance from Earth, Gravity Fields, and Hostile/Closed Environments. Research performed using STASH will be an essential first step toward acquiring fundamental knowledge about the ability of hibernation to lessen the health risks of space. This knowledge will inform development of both biomimetic drug countermeasures and the future infrastructure needed to support torpor-enabled human astronauts engaged in interplanetary missions. We feel that STASH is the epitome of the high-risk, high-reward projects for which NIAC was established.
