The findings, published recently in the Monthly Notices of the Royal Astronomical Society, could provide astronomers with important information on the history of the solar system, the formation of stars, and the creation of chemicals that may have formed the basis for planets and even life on Earth.
“Shock waves can teach us valuable information about the history of our solar system,” said Wayne Roberge, lead author and professor of physics, applied physics, and astronomy at Rensselaer. “If we can understand shock waves — how they move, what leads to their formation, their temperature — we can begin to understand where we came from and what our galaxy went through five billion years ago.”
The mathematical solution developed by Roberge and his colleague, adjunct professor Glenn Ciolek, reveals the force and movement of shock waves in plasma, the neutral and charged matter that makes up the dilute “air” of space. Unlike many previous studies of its kind, the researchers focused specifically on shock waves in plasma, which move matter in very different ways than the uncharged air on Earth.
According to the researchers, the findings could influence the success of research conducted by NASA’s upcoming mission, the Stratospheric Observatory for Infrared Astronomy (SOFIA), a modified Boeing 747SP aircraft with an infrared telescope expected to begin test flights in the coming months. Roberge noted that the findings could also be important for studies using NASA’s Spitzer Space Telescope (the infrared sister of the Hubble Telescope).
“Astronomers are now venturing into infrared telescopes, which allows you to look deeper into space,” Roberge said. “But because they can only detect heat, the search for chemicals in deep space using infrared technology is greatly hindered in cold interstellar space.” Super-hot shock waves are like fiery arrows in the sky when viewed through an infrared telescope, pointing out the origins and destination of chemicals throughout the universe, Roberge said.
“Our mathematical solution will help point astronomers in the right direction when they look at shock waves,” he said. “It lets them know what they should discover. We hope the actual space images developed in the coming months and years prove our calculations to be correct.”
As shock waves travel, they heat and condense interstellar plasma, forming new chemical compounds through intense heat and pressure. The motion of shock waves also distributes the chemical products around the galaxy. On Earth, shock waves are commonly associated with supersonic aircraft and explosions. In space, shock waves are commonly associated with the birth or death of a star.
When stars are born, they often emit jets of matter moving at hundreds of thousands of miles per hour. The impact of these jets onto surrounding material creates an extreme and sudden disturbance. This material does not have time to react to the sudden pile-up of energy and mass. Shock waves lash out into the surrounding plasma to expel the sudden force. These shock waves spread material through space, potentially “seeding” new solar systems with chemicals that may be important for life.
“Now that we understand how fast and far these waves move in space, we can begin to understand how chemicals, including chemicals necessary for life, can be formed by shock waves and spread around the universe to form new stars, planets, and life,” Roberge said.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
