Death plunge of galaxies and the longest known tail revealed by NASA

[ad_1] Change is a constant and that happens on the tiny scale of a human being to those of the biggest galaxies in the world. Now, NASA has detected a group of galaxies plunging into the Coma galaxy cluster, but the significant part is that it is leaving behind the longest known tail of superheated gas behind a galaxy group ever found.NASA's Chandra X-ray Observatory snapped the galaxy group NGC 4839. First, know what a galaxy group is as opposed to galaxy cluster. Galaxy groups are collections of about 50 galaxies or less and galaxy clusters can contain hundreds or thousands of galaxies. Both of these are enveloped by huge amounts of superheated pools of gas. They represent a significant portion of the mass in galaxy groups or clusters. Galaxy group NGC 4839 is located near the edge o...

NASA Astronomy Picture of the Day 3 May 2023: The stunning Centaurus A Galaxy

[ad_1] Stars, which illuminate the darkness of space, are formed in a giant cloud of dust and gas in space, known as a Nebula. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. According to NASA, 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.Today's NASA Astronomy Picture of the Day is the elliptical galaxy NGC 5128, also known as Centaurus A. This peculiar galaxy is located about 11 million light-years away towards the constellation of Centaurus and spans about 60,000 light-years across. According to NASA, Centau...

NASA Astronomy Picture of the Day 12 April 2023: Star cloud in the Andromeda Galaxy

[ad_1] The Andromeda Galaxy is home to several interesting objects, including globular clusters, planetary nebulae, and supernovae. It is one of the most distant, yet easily visible objects to the eye. Since Andromeda is one of the most easily seen celestial objects, it is unclear who discovered it. However, the first written observation of the Andromeda Galaxy can be found in Persian astronomer Abd al-rahman al-Sufi's The Book of Fixed Stars which dates back to the year 964.Today's NASA Astronomy Picture of the Day is the star cloud NGC 206 in the Andromeda Galaxy. It is the brightest star cloud in the galaxy as seen from Earth. Also known as Messier 31, it is a spiral galaxy located approximately 2.5 million light-years away from Earth in the constellation Andromeda. According to NASA...

NASA Astronomy Picture of the Day 22 March 2023: Andromeda Galaxy, 2x of Milky Way Galaxy

[ad_1] The Andromeda Galaxy is home to several interesting objects, including globular clusters, planetary nebulae, and supernovae. It is one of the most distant, yet easily visible objects to the eye. Also known as Messier 31, it is a spiral galaxy located approximately 2.5 million light-years away from Earth in the constellation Andromeda. One of the most striking features of Andromeda is its bright central region, known as the nucleus, which is home to a supermassive black hole. Apart from this, the galaxy also has spiral arms rich in dust and gas.Today's NASA Astronomy Picture of the Day is the Andromeda Galaxy. According to NASA, the Andromeda Galaxy is twice the size of our own Milky Way Galaxy, spanning across nearly 260,000 light-years and containing over 1 trillion stars. Disc...

NASA Astronomy Picture of the Day 23 January 2023: Hubble snaps collision of galaxies

[ad_1] NASA’s Astronomy Picture of the Day is a stunning snapshot of two galaxies colliding almost 400 million light-years away from Earth. NASA Astronomy Picture of the Day 23 January 2023: Galaxies are large collections of stars, gas, dust, and dark matter held together by gravity. They come in a variety of sizes, from small dwarf galaxies with only a few billion stars to giant elliptical galaxies with trillions of stars. Although most galaxies have elliptical shapes, a few have unusual shapes like toothpicks or rings. 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, according to NASA.NASA's Astronomy Picture of the Day is a snapshot of a stunning pair...

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...

NASA James Webb Space Telescope uncovers star formation in cluster’s dusty ribbons

[ad_1] NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from the NASA James Webb Space Telescope. NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA's James Webb Space Telescope. NCG 346 is located in the Small Magellanic Cloud (SMC), a dwarf galaxy close to our Milky Way. The SMC contains lower concentrations of elements heavier than hydrogen or helium, which astronomers call metals, compared to the Milky Way. Since dust grains in Space are composed mostly of metals, scientists expected there would be low amounts of dust, and that it would be hard to detect. New data from Webb reveals the opposit...

NASA Astronomy Picture of the Day 4 January 2023: Cometary Globule seen near a galaxy

[ad_1] NASA’s Astronomy Picture of the Day is a mesmerizing picture of a star-forming region which resembles comets, known as Cometary Globules. Cometary Globules are small clouds of gas and dust in the Milky Way Galaxy. What's striking is that these globules have morphology just like comets. They have compact and opaque heads with long and luminous tails. According to NASA, the globules are most likely dense clumps of gas and dust that existed before the hot, massive stars were born. But once the stars began to irradiate and destroy their surroundings, the clumps became visible when their less dense surroundings were eroded away. They are hydrogen-rich and consist of carbon oxides and helium.Like Nebulae, globules are also the birthplace of stars. They are known to be one of the cold...
