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...

WOW! NASA Hubble Space Telescope spots RARE triple galaxy collision

[ad_1] The NASA Hubble Space Telescope has captured a sensational image. The latest image taken by the in-space telescope showcases three different galaxies which are headed for a collision. While such collisions are common, this one is rare, as each of the trio is currently in the midst of producing new stars. As they combine to form a single large galaxy, the spiral structure of each will be destroyed by gravitational interactions between the three. This extremely rare triple galaxy collision is taking place in the Bootes constellation.This Hubble Space Telescope image is part of a project which is investigating the origins of the largest galaxies in the universe. Astronomers call such galaxies Brightest Cluster Galaxies (BCGs). They are created either when a large galaxy consumes sm...

NASA Astronomy Picture of the Day 15 February 2023: Beautiful Airglow over France

[ad_1] Auroras are one of the most visually stunning sky phenomena visible on Earth with naked eyes. The solar particles released during interaction of a solar storm with Earth's magnetic field further interact with the various gases present in our atmosphere and form stunning Auroras. However, auroras are not the only visually-pleasing sky phenomena. One other phenomenon takes place, but it is much rarer than auroras. It is known as Airglow.According to NASA, Airglow is a type of chemiluminescence from chemical interactions between oxygen, nitrogen, and other molecules in the upper atmosphere. It occurs in the form of dayglow and nightglow. Nightglow is more easily visible during the dark as airglow is just one billionth as bright as our Sun. NASA's Astronomy Picture of the Day is a s...
