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.

Why Quasars are so Awesome | PBS Space Time - astrophysics/cosmology
Supermassive black holes create accretion disks,or quasars,when gas is swept into the disks.Quasi-stellar radio source 3C273 was discovered by a radio telescope in Australia.Jets of material are sometimes produced by quasars that travel near the speed of light.Quasars are also called an Active Galactic Nucleus,since they are associated with a supermassive black hole at the center of a galaxy.Quasars are so bright,we can see them at the edge of the universe.*Dr.Matt O'Dowd is an Australian astrophysicist and the presenter,writer or co-writer of PBS Space Time.*Cosmology is the study of the origin,evolution and structures of the universe.

How Supernovas Act as Universe’s Largest Particle Accelerators - YouTube - PBS Space Time - astrophysics
In 1912,Victor Hess discovered cosmic rays,ascertaining their non-solar origin,and received a Nobel Prize for this a few decades later.Most cosmic rays come from supernovae.Enrico Fermi discovered how shock waves can send particles out at vastly higher speeds than the waves themselves travel at.A shock wave is a tsunami of both charged particles and magnetic field.Shock waves can accelerate particles to a large fraction of the speed of light.Cosmic rays are detected by the Pierre Auger Observatory in Argentina and by the ISS Cosmic Ray Energetics And Mass (CREAM) detector.*Dr.Matt O'Dowd is an Australian astrophysicist and presenter and writer or co-writer of PBS Space Time.

This Just In:First Interstellar Meteor Confirmed
According to The Harvard Gazette,two scientests with the Harvard University Department of Astronomy,Dr.Amir Siraj and Dr.Harvey Loeb,wrote a paper called "Discovery of a meteor of interstellar origin."The paper described the meteor as originating from an unbound hyperbolic orbit,or interstellar space.This meteor was discovered when Dr.Siraj,at the suggestion of Dr.Loeb,went combing through NASA's Center for Near Earth Object Studies (CINEOS) and found CINEOS 2014-01-08,a meteor that measured only 1.5 ft/.457 m across.It was traveling an estimated 45 kilometers per second/100,662.1 mph and ignited into a fireball off the coast of Papua,New Guinea on 8 JAN 2014.This was three years earlier than interstellar object Oumuamua.Comet 21/Borisov was discovered by Crimean amateur astronomer and telescope maker Gennadiy Borisov on 29 AUG 2019.*Dr.Siraj said:But what was unusual about this meteor was that this object had a very high impact speed and the unusual direction at which it encountered our planet.Anything traveling that fast is too fast to be captured by the Sun's gravity.It must have been ejected by a neigbouring star and sent our way if it was traveling with such velocity.*On 1 March 2022,LTGEN John E. Shaw,Deputy Commander U.S. Space Force,sent a memorandum to NASA Science Mission Directorate,then under Dr.Thomas Zurbuchen.Dr.Joel Mozer,chief scientest of Space Operations Command,the U.S. Space Force service element of U.S. Space Command,reviewed analysis of additional data available to the Department of Defense related to the finding.Dr.Mozer confirmed that that the velocity estimate reported to NASA was sufficiently accurate to indicate an interstellar trajectory.

Mission to Psyche: One Year Into the Spacecraft’s Journey to a Metal-Rich Asteroid - YouTube - solar system studies
All of Psyche's instruments are working:the magnetometer;the gamma ray spectrometer;the neutron spectrometer;the imagers;and the gravity experiment.The Hall thruster engine will be the first such engine used outside the Earth/Moon system.The Hall thruster is an ion thruster engine.An ion is an atom or molecule with an electric charge due to the loss or gain of one or more electrons.Hall thrusters use a magnetic field to limit their electrons' axial motion and then use them to ionize propellant.The most common propellants used are Xenon and Krypton.Psyche could reveal some of the early history of the solar system.Some asteroids are believed to be planetesimals,chunks of material left over from the planet formation process.The definition of a planetesimal is a minute planet,a body that could or did come together with many others under gravitation to form a planet. *Credit:NASA/Jet Propulsion Laboratory-California Institute of Technology/ASU

Tour: Sagittarius A East - YouTube - astrophysics - NASA Chandra X-ray Observatory
Saggitarius A East (Sagt A East) was thought to have been a typical supernova explosion of a massive star.Now ,however,after a longer study with Chandra,astronomers have ascertained that,in fact,Sagt A East is actually where a white dwarf star exploded.White dwarfs are the shrunken stellar embers of a fuel-depleted star like our Sun that isn't large enough to supernova.The explosion is the result of thermonuclear reactions that travel quicky through a white dwarf when it pulls too much material from a companion star or merges with another white dwarf,causing the destruction of the white dwarf and a stunning flash of light.Explosions of a white dwarf are a crtitcal source of elements critical to life on Earth such as iron,nickel and chromium.Such elements are only created in the nuclear furnaces of stars or when stars explode.*Credit:NASA/Jet Propusion Laboratory-California Institute of Technology*Text by Chandra and edited by Andrew Taylor

🌎 LIVE Asteroid Apophis Near Earth Countdown ☄️ NASA Eyes - YouTube - WorldCam - solar system studies
It all began late one night in June 2004 with a small dot swimming into view through the optics of NSF Kitt Peak National Observatory in the Arizona mountains.Astronomer Fabrizio Bernardi and two colleagues flagged the dot as a possible newly discovered asteroid and confirmed its space rock status in short order.9942 Apophis was intriguing but unremarkble-an object the width of a few hundred meters (now estimated at 340 m/1000 ft across) about 770 million km/478,455,818 mi from Earth.Calculations in recent years have proven the asteroid will safely glide past Earth in 2029 and 2036.In 2029,9942 Apophis should pass Earth at a nominal distance of 31,000,000 km/19,662,000 mi from Earth.*According to NASA,asteroids are small space rocks that orbit the Sun.They are remanants from the early formation of the solar system.They are classified as C-type (carbonaceous);M-type (metallic);or S-type (silicaceous).Asteroids are found primarily between the orbits of Mars and Jupiter in the main asteroid belt.They are rocky bodies with no atmosphere.*Notes by WorldCam and edited and augmented by Andrew Taylor
