2024年7月27日 · Planetary nebulae form during the death of low-mass to medium-mass stars. When such stars die, they expel their outer layers into space. These expanding shells of gas form a huge variety of unique shapes – rings, hourglasses, rectangles, and more – that show the complexity of stellar death.

2024年5月20日 · Flip through Hubble's numerous Flickr albums and see astronauts at work in space, behind the scenes of mission operations, and Hubble's iconic images from nebulae to gravitational lens. M57, or the Ring Nebula, is a planetary nebula, …

You can explore Hubble’s beautiful collection of planetary nebula images here. Using Hubble, astronomers caught a rare glimpse of the nebula Hen 3-1357, nicknamed the Stingray nebula, fading precipitously over just the past two decades. Even though the Universe is constantly changing, most processes are too slow to be observed within a human ...

A new study using Hubble observations has found that bipolar planetary nebulae located towards the central bulge of our Milky Way appear to be strangely aligned in the sky — a surprising result given their varied histories.

2025年1月28日 · Radiation from the white dwarf causes the gas to glow, creating a unique and beautiful formation called a planetary nebula. The name comes from the early days of astronomy, when observers thought the dim forms they saw through …

2021年11月29日 · NGC 6891 is a bright, asymmetrical planetary nebula in the constellation Delphinus, the Dolphin. This Hubble image reveals a wealth of structure, including a spherical outer halo that is expanding faster than the inner nebula, and at least two ellipsoidal shells that are orientated differently.

The nebula is located 1,800 light-years away in the southern constellation Musca. Hubble's image is the most detailed yet made of this object. Its double bipolar or quadrupolar structure could be explained by the presence of a second star orbiting the central star and influencing the pattern of mass ejection during its nebula-producing death ...

2020年6月18日 · Hubble was recently retrained on NGC 6302, known as the "Butterfly Nebula," to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor "wings" of gas.

2013年10月17日 · The Hubble Space Telescope has imaged striking details of the famed planetary nebula designated NGC 2818, which lies in the southern constellation of Pyxis (the Compass). The spectacular structure of the planetary nebula contains the outer layers of a star that were expelled into interstellar space.

2 天之前 · This image from NASA’s Hubble Space Telescope, released on Feb. 4, 2025, shows the gargantuan galaxy LEDA 1313424, aptly nicknamed the Bullseye.A far smaller blue dwarf galaxy went through the Bullseye’s center, leaving nine star-filled rings. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using ...
