This video morphs archival data from the NASA/ESA Hubble Space Telescope to reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceedingly rare, say researchers. The video presents the Stingray nebula as it was observed by Hubble in 2016 and then fades to Hubble's view from 1996. When compared, these Hubble images show a nebula that has drastically dimmed in brightness and changed shape. Bright blue shells of gas near the centre of the nebula have all but disappeared, and the wavy edges that earned this nebula its aquatic-themed name are virtually gone. The young nebula no longer pops against the black velvet background of the distant Universe.

Frank Summers, Space Telescope Science Institute Massive stars do not go gentle into that good night. They rage against the dying of the light in titanic supernova explosions. These stars, more than 10 times the mass of our sun, exhaust their nuclear fuel in less than 1 percent of the Sun's lifetime. Their brilliant blasts, in which a single star can outshine an entire galaxy, serve as both galactic recycling engines and cosmic beacons. The stellar remains range from the densest objects in the universe to gossamer gas filaments expanding across interstellar space. In one particular supernova remnant, the Crab Nebula, its 3D nested structure showcases the energetics and interconnections revealed by multiwavelength astronomy. Recorded live on Tuesday, February 4, 2020, at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A. More information: www.stsci.edu/public-lectures

In the year 1054 AD, Chinese sky watchers witnessed the sudden appearance of a "new star" in the heavens, which they recorded as six times brighter than Venus, making it the brightest observed stellar event in recorded history. This "guest star," as they described it, was so bright that people saw it in the sky during the day for almost a month. Native Americans also recorded its mysterious appearance in petroglyphs. Observing the nebula with the largest telescope of the time, Lord Rosse in 1844 named the object the "Crab" because of its tentacle-like structure. But it wasn't until the 1900s that astronomers realized the nebula was the surviving relic of the 1054 supernova, the explosion of a massive star. Now, astronomers and visualization specialists have combined the visible, infrared, and X-ray vision of NASA's Great Observatories to create a three-dimensional representation of the dynamic Crab Nebula. Certain structures and processes, driven by the pulsar engine at the heart of the nebula, are best seen at particular wavelengths. The multiwavelength computer graphics visualization is based on images from the Chandra X-ray Observatory and the Hubble and Spitzer space telescopes. The new video dissects the intricate nested structure that makes up this stellar corpse, giving viewers a better understanding of the extreme and complex physical processes powering the nebula. The powerhouse "engine" energizing the entire system is a pulsar, a rapidly spinning neutron star, the super-dense crushed core of the exploded star. The tiny dynamo is blasting out blistering pulses of radiation towards us 30 times a second with unbelievable clockwork precision. The visualization is one of a new generation of products and experiences being developed by the NASA's Universe of Learning program. It helps illustrate the power of what astronomers call “multiwavelength” astronomy where different types of light are combined to get a more complete understanding of the Universe and objects within it.

This visualization features a three-dimensional multiwavelength representation of the Crab Nebula, a pulsar wind nebula that is the remains of an exploded star. The movie is based on images from NASA’s three Great Observatories: the Chandra X-ray Observatory and the Hubble and Spitzer Space Telescopes. The movie begins by showing the Crab Nebula in context, pinpointing the location of the observed supernova in the constellation Taurus. This view zooms in to present the Hubble, Spitzer, and Chandra images of the Crab Nebula, each highlighting one of the nested structures in the system. The video then begins a slow buildup of the three-dimensional X-ray structure, showing the pulsar and disk of energized material, and adding jets of particles firing off from opposite sides of the energetic dynamo. Appearing next is a rotating infrared view of a glowing cloud of emission, called synchrotron radiation, enveloping the pulsar system. This distinctive form of radiation occurs when streams of charged particles spiral around the pulsar’s magnetic field lines. The visible-light outer shell of the Crab Nebula appears next. Looking like a cage around the entire system, this shell of glowing gas consists of tentacle-shaped filaments of ionized oxygen. The tsunami of particles unleashed by the pulsar is pushing on this expanding debris cloud like an animal rattling its cage. The X-ray, infrared, and visible-light models are combined at the end of the movie to reveal both a rotating three-dimensional multiwavelength view and the corresponding two-dimensional multiwavelength image of the Crab Nebula.
