A grand design spiral galaxy is a spiral galaxy with prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features. The spiral arms of a grand design galaxy extend clearly around the galaxy, covering a significant portion of the galaxy's circumference.

2024年12月28日 · Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named...

2025年1月3日 · JWST has spotted a huge, ultramassive galaxy as it appeared 12.8 billion years ago, so intricately structured that it can only belong to the most spectacular category of galaxies: the grand design spiral.

2024年12月19日 · Galaxies in the early universe tend to be clumpy, but the new JWST discovery of a "grand design" spiral galaxy just 1.5 billion years after the Big Bang has scientists stumped.

2007年5月28日 · The sharpest image ever taken of the large "grand design" spiral galaxy M81 is being released today at the American Astronomical Society Meeting in Honolulu, Hawaii. This beautiful galaxy is tilted at an oblique angle on to our line …

2024年12月16日 · Indian astronomers report the detection of a new grand-design galaxy with the James Webb Space Telescope (JWST). The newfound galaxy, which received designation A2744-GDSp-z4, is relatively...

2024年12月13日 · NGC 5643 is a grand design spiral, which refers to the galaxy’s symmetrical form with two large, winding spiral arms that are clearly visible. Bright-blue stars define the galaxy’s spiral arms, along with lacy reddish-brown dust clouds and pink star-forming regions.

2024年8月25日 · M100 is a stunning example of a grand-design spiral galaxy. This detailed Hubble image reveals individual stars within the galaxy’s prominent spiral arms. These dusty structures swirl around the galaxy’s nucleus and are marked by a flurry of star formation.

Explanation: Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. The large galaxy of over 100 billion stars has well-defined spiral arms, similar to our own Milky Way.

BX442 (Q2343-BX442 [1]) is a grand design spiral galaxy of type Sc. [1] It has a companion dwarf galaxy. It is the most distant known grand design spiral galaxy in the universe, with a redshift of z=2.1765 ± 0.0001. [1]
