“Firefly Sparkle” Reveals Early Galaxy - YouTube - NASA Goddard - cosmology

Dr.Johnathan Gardner,Former Deputy Senior Project Scientist for JWST,presents the latest JWST images of the "Firefly Sparkle" galaxy,showcasing intricate details and structures.There is so much going on in this seemingly tiny galaxy,it appears like a swarm of fireflies on a warm summer night.This galaxy is gleaming with star clusters.This is the first time the NASA/ESA/CSA James Webb Space Telescope has detected a galaxy that existed around 600 million years after the Big Bang.This was made possible by a phenomenon known as gravitational lensing that was predicted by Einstein's Theory of General Relativity,in which the gravity of a large celestial object is strong enough to warp spacetime,allowing us to peer at a very distant celestial object.*Credit:NASA Goddard Spaceflight Center in Greenbelt,Maryland.*Cosmology is the study of the origin,evolution and structures of the universe.*Text by NASA Goddard and edited and augmented by Andrew Taylor

James Webb Space Telescope delivers amazing view of spiral galaxy - See in 4K - YouTube - Space.com - astrophysics

First is shown spiral galaxy NGC 2090 by the NASA/ESA Hubble Space Telescope.Next is shown NGC 2090 by the NASA/ESA/CSA James Webb Space Telescope usinf its Mid-Infrared Instrument (MIDI) and Near-Infrared Camera (NIRCam).NGC is about 37 million light years from Earth in the constellation Columbia,so right next door.

Tbe NASA/ESA/CSA James Webb Space Telescope has caputred images of Arp 107,a merger between an elliptical and spiral galaxies in the near-infrared and middle-infrared wavelengths.Arp 107 is 465,000,000 light years from Earth,so right next door.*Cosmology is the study of the origin,evo;ution and structures of the universe.*The merger of galaxies results in a burst of new star formation.The supermassive black hole at the center of the spiral galaxy makes it extremely bright because of its accretion disk,an Active Galactic Nucleus.

JWST Discovered The Farthest Star Ever Seen! - YouTube - PBS Space Time - astrophysics/cosmology - 2023 episode

The NASA/ESA Hubble Space Telescope first discovered the Blue Giant star Earendel,a name that means "morning star."It couldn't tell us much about it because it discovered it with its ultraviolet mode.It took the NASA/ESA/CSA James Webb Space Telescope,which has a mirror 50x larger than Hubble's,to begin to unravel Earendel's mysteries.Earendel is 28 billion light years from Earth with a redshift of 6.2.Both discoveries were made with a phenomenon predicted by Einstein's General Theory of Relativity called gravitational lensing,in which a celestial object with a large gravitational field warps spacetime,in this case a galaxy cluster,such that an object in the background is magnified greatly,giving us a view into the early universe.Earendel is a class b blue giant star with a mass at least 50,000 times larger than the Sun's and has a surface temperature of at least 50,000 degrees Kelvin/89,540.33 degrees F.Earendel is also believed to have a red giant companion.It is possibly one of the first generation of stars that emerged out of the dark matter that remained after the Big Bang.*Cosmology is the study of the origin,evolution and structures of the universe.*Dr.Matt O'Dowd is an Australian astrophysicist and the presenter and writer or co-writer of PBS Space Time.*Further studies are ongoing to refine the information.

Pillars of Creation Star in New Visualization from the NASA/ESA Hubble and the NASA/ESA/CSA Webb Space Telescopes - YouTube

Made famous in 1995 by the NASA/ESA Hubble Space Telescope,the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations everywhere with their haunting,ethereal beauty.Now,NASA has released a new 3D visualization of these towering celestial structures using data from the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope.This is the most comprehensive amd detailed multiwavelength movie yet of this star-birthing region based on observational data from a science paper led by Anna Macleod,as associate professor at the University of Durham,United Kingdom.Macleod also served as a science advisor on the project.*Text by NASA and edited by Andrew Taylor* Credit:Greg Bacon,Space Telescope Science Institute (STsci) in Baltimore,Maryland:Producer*Frank Summers (STsci):Director*Anna Macleod (Durham):Science Advisor*The Eagle Nebula is about 7,000 light years from Earth in the constellation Serpens.*Cosmology is the study of the origin and structures of the universe.
