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.

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.

Watch the R Aquarii binary star system evolve in Hubble imagery time-lapse - YouTube - Space.com - astrophysics

The NASA/ESA Hubble Space Telescope has captured imagery of the R Aquarri binary star system from 2014-2023.The images have been time-lapsed to show the evolution of the region.R Aquarri is a symbiotic star system in the constellation Aquarius.It is believed to be a coupling of a white dwarf star with a Mira-type variable star,a red giant.The orbital period is about 44 years.It has a distance of about 218 parsecs/711 light years,so is right next door.By its gravitational pull,the white dwarf draws in material from the red giant and sometimes ejects some of the surplus in loops to form the nebula seen in the NASA/ESA Hubble Space Telescope images.The red giant star both pulsates and changes temperature,causing a very large change in brightness.Its brightness has a total range of 750 times.The pulsations occur every 390 days,give or take some days.*Material by Space.com and edited and augmented by Andrew Taylor

Jupiter’s Great Red Spot Is Shaking - YouTube - NASA Goddard - planetary science

Jupiter's iconic Great Red Spot,a storm larger than Earth,has fascinated scientists for over 150 years.But thanks to the NASA/ESA Hubble Space Telescope,we're now seeing this legendary storm in a whole new light.Recent observations show that the Great Red Spot is wobbling and fluctuating in size.Captured in high resolution images over 90 days,Hubble's data reveals the storm speeding up,slowing down and changing shape-surprising even seasoned scientists.The team predicts that the storm will continue to shrink and eventually stabilize,but right now,it's still full of dynamic surprises.Credit:NASA Goddard Spaceflight Center in Greenbelt,Maryland*Material by NASA Goddard and edited by Andrew Taylor

Hubble Spots Black Hole Beam Causing Stellar Eruptions - YouTube - NASA Goddard - astrophysics

In a surprise finding,the NASA/ESA Hubble Space Telescope has discovered that the jet from a supermassive black hole at the core of M 87,a huge spiral galaxy 54 million light years away,seems to cause stars to erupt along its trajectory.The stars,are called novae,are not caught inside the jet,but are in a dangerous spot near it.A nova explosion occurs when an aged,swollen normal star spills hydrogen onto a burned out white dwarf companion star.When the white dwarf has collected a big enough layer of hydrogen,it explodes into space.The white dwarf survives to resume the cycle.*Credit:NASA Goddard Space Flight Center in Greenbelt,Maryland*Text by NASA Goddard and edited by Andrew Taylor

Hubble’s Inside the Image: Stephan's Quintet - YouTube - NASA Goddard - cosmology

The four distant galaxies of Stephan's Quintet are about 290 million light years away,while the closer galaxy is only about 40 million light years away,so right next door.The distant galaxies are headed for a merger.It's believed that most galaxies have experienced a merger,including the Milky Way.*Cosmology is the study of the origin,evolution and structures of the universe.*Dr.Jennifer J. Wiseman is a senior astrophysicist at NASA Goddard Spaceflight Center in Greenbelt,Maryland,and Project Scientist for the NASA/ESA Hubble Space Telescope.She got a bachelor's degree in Physics from MIT and a PhD in Astronomy from Harvard University.For her role as Hubble Project Scientist,she made the list of women in leadership positions on astronomical instrumentation projects.Dr.Wiseman is a Christian.*Information by NASA Goddard and augmented by Andrew Taylor

Hubble’s Inside the Image: Cat’s Eye Nebula - YouTube - astrophysics/cosmology - NASA Goddard

The NASA/ESA Hubble Space Telescope has captured a stunning image of the Cat's Eye Nebula (NGC 6543),one of the most complex planetary nebulae known,with its intricate structure of concentric rings and high density knots.Dr.Ken Carpenter of NASA Goddard Space Flight Center delves into the beauty of this cosmic jewel discusses the the critical role Hubble plays in unraveling the secrets of stellar evolution and the lifecycle of stars.*Cosmology is the study of the origin of the universe and its structures.*Video credit:ESA/Hubble-M.Kornmesser and L.L.Christensen*Text by NASA Goddard and edited by Andrew Taylor
