The Cat’s Eye Nebula | Hubble’s Inside the Image | NASA Goddard FriendsofNASA.org: NASA's Hubble Space Telescope captured a stunning image of the Cat's Eye Nebula, one of the most complex planetary nebulae known, with its intricate structure of concentric rings and high-density knots. In this video, Dr. Ken Carpenter delves into the beauty of this cosmic jewel and discusses the critical role Hubble plays in unraveling the secrets of stellar evolution and the lifecycle of stars. The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the Hubble Space Telescope has revealed knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN).

This is the Cat's Eye Nebula that's in the constellation Draco, about 3100 light years from us. It's called the the Cats I Nebula because of the resemblance the appearance of of cat's eyes. We have at the very center of bright Star. The star has been in the process of dying for many thousands of years. When the start gets near the end of its life, it expands inside as it runs out of hydrogen at the center and has to turn to fusing helium instead of hydrogen. The star expands and it can get very unstable as you get near the end of its lifetime, which is when it starts throwing off these pulses and material. You'll see rings. Here is a whole set of 11 different rings that go all the way around the star that almost look like tree rings. In addition to these rings of light that you see, you see these pointed nebula which are jets of material coming out along the North and South magnetic poles. I love to think of this as providing us a fossil record in the same way that if you look through layers of of stone or you look through a slice of a tree where you see the tree rings, it allows you to see what was happening at different periods of time in the history of the star. So somewhere like 15,000 years ago is when the instability stage of the star occurred and started throwing off the material to form the the rings of of dust, and then more recently 1000 years. To go, it started throwing off the the hot gases which are glowing at the center and give you the very intricate patterns and structures that you see now. O you've got jets coming out at the magnetic poles, you have ellipsoids and circles of hot gas, and you've got spherically symmetric rings of dust all wrapped up in in one little package. It's the foundations for the next generation of stars. So this Mitchell gets thrown out into what we call the interstellar medium, the space between the stars and the material in the in that space between the stars and that will later on collect together gravitationally. We'll pull together and form new stars and new solar systems.

The Veil Nebula | Hubble’s Inside the Image | NASA Goddard FriendsofNASA.org: NASA's Hubble Space Telescope has captured a breathtaking image of the Veil Nebula, a remnant of a supernova explosion that showcases delicate, wispy filaments of ionized gas. In this video, Dr. Ken Carpenter delves into the stunning details of the Veil Nebula and explains how Hubble's observations shed light on the complex processes involved in the aftermath of a star's explosive death. The Veil Nebula lies around 2,100 light-years from Earth in the constellation of Cygnus (The Swan), making it a relatively close neighbor in astronomical terms. The Veil Nebula is the visible portion of the nearby Cygnus Loop, a supernova remnant formed roughly 10,000 years ago by the death of a massive star. The Veil Nebula’s progenitor star—20 times the mass of the Sun—lived fast and died young, ending its life in a cataclysmic release of energy. Despite this stellar violence, the shockwaves and debris from the supernova sculpted the Veil Nebula’s delicate tracery of ionized gas—creating a scene of surprising astronomical beauty.

Time-lapse: Evolution of R Aquarii Binary Star System (2014 to 2023) | Hubble FriendsofNASA.org: This video features five frames spanning from 2014 to 2023 of R Aquarii, a symbiotic binary star that lies only roughly 1,000 light-years from Earth in the constellation Aquarius. This is a type of binary star system consisting of a white dwarf and a red giant that is surrounded by a large, dynamic nebula. These frames show the brightness of the central binary changing over time due to strong pulsations in the red giant star. The central structures can also be seen to be spiraling outwards due to their interaction with material previously ejected by the binary. This time-lapse highlights the value of Hubble’s high resolution optical observations in the changing Universe, known as time-domain astronomy. Credit: NASA, European Space Agency, M. Stute, M.

Realistically speaking (yes, realistically) how much do you believe a #spacecruise out to Messier 27 would be worth? What would the industry demand 'be' if affordable space travel or corporate events to such destinations were possible (in our lifetime)? #newscience #postquantum #warpdrive #postwarpdrive #CTPGravityDrive

Apple Core Nebula in Vulpecula | Digitized Sky Survey 2 FriendsofNASA.org | High-res image: https://lnkd.in/gctn7Cag A star field image of the notable planetary nebula Messier 27 to the right of center. The Apple Core Nebula—also known as Messier 27 or NGC 6853—is a typical planetary nebula and is located in the constellation Vulpecula (The Fox). The Apple Core Nebula is about 850 light-years away from Earth and about 1.5 light-years in diameter (although distance and size are very poorly constrained). It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as number 27 in his famous list of extended sky objects. The field-of-view is approximately 0.9 x 0.6 degrees. The Digitized Sky Survey (DSS) is a ground-based imaging survey of the entire sky in several colors of light produced by the Space Telescope Science Institute through its Guide Star Survey group.

Dwarf 'Starburst' Galaxy NGC 4449 | James Webb Space Telescope FriendsofNASA.org: The James Webb Space Telescope captured this image of “starburst” galaxy NGC 4449. Starbursts are intense periods of star formation usually concentrated at a galaxy’s core. However, NGC 4449’s activity is much more widespread—likely due to past interactions with its galactic neighbors. Astronomers can study this galaxy to look into the past. NGC 4449 is similar to early star-forming galaxies that also grew by merging with other systems. Distance: 12.5 million light-years away Image Description: This is a close view of the central area of a dwarf galaxy. A huge number of stars fill the entire galaxy as tiny glowing points. They are brightest around the galaxy’s shining core. Thick clouds of gas and dust billow out across the scene, curling like moving flames. They glow in warm colors following their location: orange around the galaxy’s core, and around glowing star clusters in the bottom-left, and dark red elsewhere. Video Credit: ESA/Webb, NASA & CSA, A.

Globular Star Cluster Messier 2 in Aquarius: Largest of its Kind | Hubble FriendsofNASA.org | High-res image: https://lnkd.in/gzedKEju Star clusters are commonly featured in cosmic photoshoots, and are also well-loved by the keen eye of the NASA/European Space Agency Hubble Space Telescope. These large gatherings of celestial gems are striking sights—and the subject of this picture, Messier 2, is certainly no exception. Messier 2 is located in the constellation of Aquarius (The Water-Bearer), about 55,000 light-years away. It is a globular cluster, a spherical group of stars all tightly bound together by gravity. With a diameter of roughly 175 light-years, a population of 150,000 stars, and an age of 13 billion years, Messier 2 is one of the largest clusters of its kind and one of the oldest associated with the Milky Way. Most of the cluster’s mass is concentrated at its center with shimmering streams of stars extending outwards into space. It is bright enough that it can even be seen with the naked eye when observing conditions are extremely good. Credit: ESA/Hubble & NASA, G. Piotto et al.

The Serpens Nebula: Objects Identified | James Webb Space Telescope FriendsofNASA.org: For the first time, a phenomenon astronomers have long hoped to image directly has been captured by the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope’s Near-InfraRed Camera (NIRCam). In this detailed image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region. The astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have a variety of orientations within one region. Here, however, they are all slanted in the same direction, to the same degree, like sleet pouring down during a storm. The discovery of these aligned objects, made possible only by Webb’s exquisite spatial resolution and sensitivity at near-infrared wavelengths, is providing information about the fundamentals of how stars are born. This video showcases the new Webb Serpens Nebula image, with notable features and objects highlighted. Credit: NASA, ESA, CSA, STScI, K. Pontoppidan (NASA’s Jet Propulsion Laboratory), J.
