00:063D Models
00:10New 3-dimensional, or 3D, models of objects in space
00:15have been released by NASA's Chandra X-ray Observatory.
00:20These 3D models allow people to view and print
00:24examples of stars in the early and end stages of their lives.
00:29These 3D models are based on state-of-the-art theoretical models,
00:33computational algorithms, and observations from space-based telescopes like Chandra
00:38that give us accurate pictures of these cosmic objects and how they evolve over time.
00:44However, looking at images and animations is not the only way to experience these data.
00:50The four new 3D printable models of Cassiopeia A, G292.0 plus 1.8,
00:58and Cygnus-loop supernova remnants, and the star known as BP Tau,
01:02let us experience the celestial objects in the form of physical structures
01:07that will allow anyone to hold replicas of these stars and their surroundings
01:11and examine them from all angles.
01:14In Cassiopeia A, astronomers combined X-rays from Chandra
01:18and infrared data from the James Webb Space Telescope
01:21to shed light on the origin of a mysterious structure they dubbed Green Monster.
01:27This revealed new insights into the explosion that created Cassi about 340 years ago from Earth's perspective.
01:36By creating a 3D model of the G292 system,
01:40astronomers have been able to examine the asymmetrical shape of the remnant
01:44that can be explained by a reverse shockwave moving back toward the original explosion.
01:49This helps them better understand this rare type of supernova explosion
01:53that contains large amounts of oxygen.
01:56The Cygnus-loop, also known as the Veil Nebula,
02:00is a supernova remnant, the remains of the explosive death of a massive star.
02:05This 3D model is the result of a simulation
02:08describing the interaction of a blast wave from the explosion
02:12with an isolated cloud of the dust and gas in between the stars.
02:17Finally, a 3D model shows a star less than 10 million years old
02:21that is surrounded by a disk of material.
02:25This object, called BP Tau,
02:27has flares that interact with a disk of material surrounding this infant star.
02:32Looking at BP Tau gives us insight into our own sun,
02:36billions of years ago.
