NASA Astronomy Picture of the Day 9 June 2023: Webb Telescope snaps Pandora Cluster

[ad_1] Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxies exist in the vastness of space, consisting of various celestial objects such as stars, clouds of dust, and gas, all of which are bound together by gravity. These galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.Today's NASA Astronomy Picture of the Day is a snapshot of Abell 2744, also known as the Pandora's Cluster of galaxies which is located about 4 billion light-years away towards the constellation of Sculptor. This galaxy cluster formed when four smaller galaxy clusters pi...

NASA Astronomy Picture of the Day 26 May 2023: Virgo cluster of galaxies

[ad_1] Galaxies which exist in the vastness of space, consist of various celestial objects such as stars, clouds of dust, and gas, all of which are bound together by gravity. Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.Today's NASA Astronomy Picture of the Day is a snapshot of the Virgo cluster of galaxies located about 50 million light-years away. According to NASA, the Virgo cluster is the nearest cluster of galaxies and contains over 2000 galaxies. This cluster also includes bright Mes...

NASA Astronomy Picture of the Day 16 February 2023: Hydra galaxy cluster

[ad_1] Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. One such galaxy cluster is the Hydra Cluster of galaxies which is one of the three large galaxy clusters within 200 million light-years of the Milky Way. Galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.NASA's Astronomy Picture of the Day is a stunning snapshot of the Hydra Cluster of galaxies surrounded by millions of stars. According to NASA, the galaxy cluster is over 100 million light-years away in the constellation Hydra. Three large galaxies near the cluster center, two yellow el...

Earliest formation of the galaxies revealed by James Webb Telescope

[ad_1] NASA's $10 billion space telescope, the James Webb Space Telescope (JWST), has been capturing breathtaking images of far-off galaxies, star clusters, black holes and more. The space telescope was launched on December 25, 2021, and despite being in service for less than two years, it has added many feathers in its cap. One of the major feats of JWST is capturing galaxy clusters which are located billions of light-years away from Earth.One of the first images captured by the JWST released in July last year, the Galaxy Cluster SMACS0723 could reveal information about the earliest formation of galaxies, when the universe was less than 1 billion years old, according to a study published in the Monthly Notices of the Royal Astronomical Society. The galaxy cluster is located at a stell...

NASA Astronomy Picture of the Day 26 January 2023: Dazzling Active Galaxy

[ad_1] NASA’s Astronomy Picture of the Day is a mesmerizing snapshot of the Active Galaxy NGC 1275 residing at the center of Perseus Galaxy Cluster. In the Universe, galaxies exist in the vast expanse of space. But they are not alone. In fact, galaxies exist in huge groups which are closely connected by gravity. Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.Galaxy Clusters are also known to contain dark matter which is invisible to telescopes since they do not emit, absorb, or reflect any...

NASA Astronomy Picture of the Day 18 January 2023: James Webb Telescope snaps Galaxy clusters

[ad_1] NASA’s Astronomy Picture of the Day is a captivating image of a galaxy cluster captured by the James Webb Telescope. The James Webb Space Telescope is impressing us with its capabilities with each passing day. NASA's $10 billion space telescope has been capturing breathtaking images of far-off galaxies, star clusters, black holes and more. The space telescope was launched on December 25, 2021 and since then it has added many feathers in its cap. One such image was of Galaxy clusters, which are some of the largest structures in the universe, containing hundreds to thousands of galaxies bound together by gravity.NASA's Astronomy Picture of the Day is a captivating image of a galaxy cluster MACS0647 in which a cluster can be seen as distorted in the foreground. Moreover, light emi...
