The Boundary Between Black Holes & Neutron Stars - YouTube - PBS Space Time - astrophysics

Gravitational waves were predicted by Einstein's Theory of General Relativity.On 14 AUG 2024,a signal was received consistent with a gravitational wave traveling at the speed of light at the Hanford LIGO in Washington State,the Livingston LIGO in Louisiana,and the Virgo LIGO in Italy.A neutron star is what's left over after a supernova.About 1.5 Suns of matter is compressed into an area the size of a small city,making the gravity 100 billion times stronger than the gravity of Earth's surface.The signal was consistent with a neutron star being in close proximity to a black hole.*Presented and written by Dr.Matt O'Dowd,an Australian astrophysicist.

Tour: Supernova 1987A Pulsar Wind Nebula - YouTube - astrophysics/cosmology

NuStar,the Nuclear Spectroscopic Telescope Array is a space observatory operated by NASA/Jet Propulsion Laboratory-California Institute of Technology.Its mission is to study the universe in high energy X-rays to better understand the dynamics of black holes,exploding stars and extreme active galaxies.Together with the NASA Chandra X-ray Observatory and the Atacama Large Millimeter/submillimeter Array,a network of 60 radio telescopes in Chile,it has been studying SN 1987A,one of the most studied objects in recent times.SN 1987A is only about 170,000 light years from Earth,so is right next door.Within SN 1987A,a neutron star,the densest object in the universe,has been ascertained that is also a pulsar,the twin bursts of energy coming out of each end being detected as pulses.*Cosmology is the study of the origin,evolution and structures of the universe.*space observatories

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

Do Neutron Stars Shine In Dark Matter? - YouTube - PBS Space Time - new video - astrophysics

Neutron stars may produce the exotic Axion,a dark matter candidate.Axions can turn into the packets of light called photons.*Neutron stars have strong magnetic fields.Axions may or may not exist,but,if they do,neutron stars produce vast quantities of these dark matter particles and are cloaked in a cloud of them.*The neutron stars that are pulsars may be the source of the mysterious Fast Radio Bursts that puzzle astronomers.Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds.Pulsars have strong magnetic fields that funnel particles accelerating to relativistic speeds,which produces two powerful beams of light.*Albert Einstein won the Nobel Prize for Physics in 1921,especially for his discovery of the photoelectric effect.Einstein's work on the photoelectric effect demonstrates that light consists of quanta,or packets of light,which we now call photons.This was a pivotal contribution to the development of quantum theory.*PBS Space Time is presented and written or co-written by Dr.Matt O'Dowd,an Australian astrophysicist.

Like all comets,Tsuchinshan-Atlas (c2023 a3) originated as a planetesimal in the Oort Cloud in the early years of the solar system.Some planetesimals coalesced to form planets,while others are dwarf planets or comets.The Oort cloud is a theoretical construct devised by the Dutch astronomer Jan Oort in 1950 as the origin of comets.It hasn't been directly observed for lack of adequate technology.It is a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 astronomical units (0.03-3.3 light years) and is in interstellar space.Planetesimals formed the four terrestrial planets:Mercury,Venus,Earth and Mars.We don't yet know if Tsuchinsan-ATLAS will be visible to the naked eye.Credit:NASA Commander Matthew Dominick photographed the comet from the ISS.

New exoplanet discovered orbiting closest single star to our Sun -YouTube - ESO - planetary science

Using ESO's Very Large Telescope (VLT),astronomers have discovered an exoplanet orbiting the closest single star to our Sun,Barnard's star,a red dwarf variable star,at about 6 light years from Earth.The exoplanet,which has a mass at least half that of Venus,has a surface temperature of 125 C/257 F,which is too hot to sustain liquid water.It was discovered by the gravitational pull it has on Barnard's star.*The VLT is part of the Paranal Observatory on Cerro Paranal,Mt.Paranal,with an altitude of 2635 m/8645 ft.It is in the Atatcama Desert of Northern Chile.The VLT is capable of both visible and infrared observation.The VLT consists of four individual telescopes,each with a primary mirror of 8.2 m/26.9 ft in diameter.They are generally operated separately,but can also be combined.*Barnard's star has the designation V2500 Ophiuchi.It is named for the American astronomer Edward Emerson Barnard,who measured its motion in 1916.Barnard's star is not visible to the naked eye.At 7-12 billion years of age,it may be one of the most ancient stars in the Milky Way.Note:Alpha Centauri is a star system,not an individual star.*Material by ESO and edited and augmented by Andrew Taylor
