“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

This week in 2022,the NASA Exploration Ground Systems Landing and Recovery Team and partners with the Department of Defense recovered a mock-up of the Lockheed Martin Orion spacecraft in the Pacific Ocean.Since then,teams and the Artemis II astronauts conducted Underway Recovery Test 11 in 2023 where they practiced reovering crew and the Orion spacecraft.Further tests are planned.*The Artemis II mission will launch from NASA Kennedy Space Center in April 2026.Its 10 day mission around the Moon will take humans farther from Earth than ever before.Crew members are NASA Commander Reid Wiseman,NASA Pilot Victor Glover,NASA Mission Specialist Christina Koch and CSA Mission Specialist Jeremy Hansen.*The recovery ship will be a Landing Dock Ship such as the USS Harpers Ferry (LSD 49).Landing Dock Ships are amphibious warfare ships equipped with a well deck for launching and recovering amphibious landing craft.*In this video,meet some of the Landing and Recovery team members.*Lockheed Martin (LMT)*Text by NASA Kennedy and edited and augmented by Andrew Taylor

What Does An Electron ACTUALLY Look Like? - YouTube - PBS Space Time - physics - new episode

An electron is a ball of energy.As Einstein discovered in his General Theory of Relativity,bound energy also has mass.An electron's classical radius is 2.818x10 (-15)m;but its true size is 10 (-17)m,or at least 100x smaller than the classical radius.Photons are excitations of the Electromagnetic Field.Electron and Positron pairs are excitations of the Electron Field and may annihilate one another.In Quantum Field Theory,each elementary particle,such as an electron,is an excitation of its own quantum field.Quantum particles consist of waves,but when we examine a specific particle,it becomes a point.*Dr. Matt O'Dowd is an Australian astrophysicist and presenter of PBS Space time and wrote this episode.

Lucy Spacecraft’s Second Slingshot of Earth - YouTube - NASA Goddard - solar system studies

Lucy is a NASA space probe that is on a twelve year mission to eight different asteroids.It is slated to visit two Main Belt Asteroids,as well as six Trojan asteroids that share Jupiter's orbit around the Sun.All encounters will be flyby encounters.The mission is named for the Lucy hominim fossils,because the study of the Trojans could reveal the fossils of planetary formation:materials that clumped together in the early history of the solar system to form planets and other bodies.*Lucy's instruments are:Long Range Reconaissance Imager (L'LORRI);Optical and Near-Infrared Imaging Spectrometer (L'RALPH) and Thermal Infrared Spectrometer( L'TES).Principal Investigator is Harold F. Levison of the Southwest Research Institute in Boulder,Colorado.Simone Marchi of SRI is the Mission's Deputy Principal Investigator.NASA Goddard Spaceflight Center in Greenbelt,Maryland executes the mission under the direction of the Planetary Mission Program Office at NASA Marshall Space Flight Center.*The Lucy spacecraft was launched from what is now Cape Canaveral Space Force Station's Space Launch Complex-41 on a United Launch Alliance Atlas V 401 rocket on 16 October 2021.*United Launch Alliance is a joint venture of Boeing Space and Defense and Lockheed Martin Space.Boeing (BA),Lockheed Martin (LMT)

Artemis II Rocket Stacking Begins at NASA's Kennedy Space Center - YouTube - Orion Program Update - O6 December 2024

Engineers and techinicians with the NASA Exploration Ground Systems Program completed stacking of the first Moon rocket segment-the left and right aft assemblies for the agencie's Artemis II Boeing Space and Defense Space Launch System solid rocket boosters (SRB)-onto Mobile Launcher I in the Vehicle Assembly Building (VAB).The first of 10 booster segments will help support the remaining rocket components,the Orion spacecraft and the European Service Module during final assembly of the Artemis II Lockheed Martin Orion spacecraft and Boeing Space and Defense Space Launch System rocket.Liftoff will be from Space Launch Complex 39B at Nasa Kennedy Space Center in April 2026.Note:Because of heat shield damage found on the Artemis I Orion spacecraft,it took engineers several months to devise a correction for the problem.Hence the mission will be delayed from November 2025 to April 2026.It will send humans farther from Earth than ever before.The Artemis II crew consists of NASA Commander Reid Wiseman,NASA Pilot Victor Glover,NASA Mission Specialist Christina Koch,and CSA Mission Specialist Jeremy Hansen.*Boeing (BA),Lockheed Martin (LMT)*Text by NASA Kennedy and edited and augmented by Andrew Taylor

The NEW Ultimate Energy Limit of the Universe - YouTube - PBS Space Time - astrophysics - new episode

The NASA/ESA/CSA James Webb Soace Telescope has discovered a new energy limit for the universe.It did so while studying supermassive black holes in the early universe,finding the new energy limit is 4,000 times greater than the old one,by studying the supermassive black hole LIG-568.The supermassive black hole's accretion disk (Active Galactic Nucleus) set the new record with its brightness.Sir Arthur Eddington is considered the father of astrophysics.He was the first scientist to verify Einstein's Theory of General Relativity by observing the bending of light caused by the Sun's gravity during a solar eclipse,which General Relativity predicted.He went on to develop the Eddington Limit.This holds that the maximum luminosity a body such as a star can achieve is balanced by the star's gravity going in.The state of balance is called hydrostatic equilibrium.There is a balance of the gas pressure pushing out and the gravity pulling in.In addition,photons,which Einstein described as packets of light,bounce off of electrons,a phenomenon called Thompson's scattering.In the most massive stars,this outward pressure starts to dominate.*This episode was presented and written by the Australian astrophysicist Dr.Matt O'Dowd.

Take a 360 Tour of COBE's Cosmic Baby Picture - YouTube - NASA Goddard - cosmology

The NASA COBE satellite operated from 1989-1993.It took the first baby picture of the universe,revealing slight temperature variations when the universe was just 380,000 years old.In the aftermath of the Big Bang,the universe was hotter and much smaller than it is now.As time went on,it cooled off and expanded to a huge extent,using the dark matter and energy residue of the Big Bang.This image shows the entire sky using four years of observations using COBE's Differential Microwave Radiometer.The central plane of our Milky Way galaxy runs across the middle and its center is marked by a white X.Red indicates hotter regions,blue colder.The fluctuations are very faint,varying by only one part in a 100,000 from the average temperature.They represent density variations in the early universe thought to have given rise to the structures that we see today.After stripping away foreground emmission arising from dust,hot gas and charged particles interacting with magnetic fields in our galaxy,COBE data revealed tiny variations in the temperature of the Cosmic Microwave Background (CMB)-the oldest light in the universe-for the first time.*Cosmology is the study of the origin,evolution and structures of the universe.*Credit:NASA Goddard Spaceflight Center in Greenbelt,Maryland*Image credit:NASA/COBE Science Team*Narrator:Thomas Essinger Hileman (NASA/GSFC)*Science Writer:Francis Reddy (University of Maryland College Park)*Text by NASA Goddard and edited and augmented by Andrew Taylor
