Such an infrared-only pulsar wind nebula is unusual because it implies a rather low energy of the particles accelerated by the pulsar’s intense magnetic field. This is an illustration of a pulsar wind nebula produced by the interaction of the outflow particles from the neutron star with gaseous material in the interstellar medium that the neutron star is plowing through. Neutron stars are also called pulsars because their very fast rotation (typically fractions of a second, in this case 11 seconds) causes time-variable emission from light-emitting regions. The observation, by a team of researchers at Pennsylvania State University, University Park, Pennsylvania Sabanci University, Istanbul, Turkey and the University of Arizona, Tucson, Arizona, could help astronomers better understand the evolution of neutron stars - the incredibly dense remnants after a massive star explodes as a supernova. One possibility is that there is a dusty disk surrounding the neutron star another is that there is an energetic wind coming off the object and slamming into gas in interstellar space the neutron star is plowing through.Īlthough neutron stars are generally studied in radio and high-energy emissions, such as X-rays, this study demonstrates that new and interesting information about neutron stars can also be gained by studying them in infrared light, say researchers. Tr’Ehnl (Pennsylvania State University)Īn unusual infrared light emission from a nearby neutron star detected by NASA’s Hubble Space Telescope could indicate new features never before seen. The disk would be made up of material falling back onto the neutron star after the supernova explosion that created the stellar remnant. The disk wasn’t directly photographed, but one way to explain the data is by hypothesizing a disk structure that could be 18 billion miles across. A visual size comparison of the largest known stars and planets can be explored, and real time animations of events like the Apophis asteroid passing near Earth in the year 2029 can be watched.This animation depicts a neutron star (RX J0806.4-4123) with a disk of warm dust that produces an infrared signature as detected by NASA’s Hubble Space Telescope. During gameplay, the player may be introduced to the regions that include the 100 largest bodies in the Solar System, the nearest 1000 stars to the Sun or the nearest 70 galaxies to the Milky Way. Real simulations include the Solar System, which includes the eight planets, five minor planets, 160+ moons, and hundreds of asteroids and predictions of future events such as the Andromeda and Milky Way galaxy collision which will occur in 3.8 to 4.5 billion years.

Dixon worked full-time on the project since 2010, founding the company Giant Army the following year.
Universe Sandbox was designed by Dan Dixon, who released the first version in May 2008. The original Universe Sandbox was only available for Windows-based PCs, but an updated version, Universe Sandbox ², was released for Windows, macOS, and Linux in 2017. Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes.
