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.

Euclid’s 208-Gigapixel glimpse into the Universe - YouTube - ESA - astrophysics/cosmology

The ESA Euclid spacecraft has released the first page of a large cosmic atlas it is photographing,amounting about 1% of the total.The ultimate purpose of the atlas and Euclid spacecraft is to explore the role of dark matter and dark energy in the universe.The first page of the atlas is a huge 208-gigapixel mosaic.The images were collected from 260 observations collected in just two weeks.It was released on 15 OCT 2024 at the International Aeronautical Congress in Milan,Italy by ESA Director General Josef Aschbacher and Director of Science Carole Mundell.*Text by ESA and edited by Andrew Taylor*Cosmology is the study of the origin,evolution and structures of the universe.*Dark matter is about 27% of the universe,while dark energy is about 68% of the universe.

with Dr.Matt O'Dowd,PhD (astrophysics),writer and host of PBS Space Time*The universe is flat.The era of radiation following the Big Bang evolved to the era of dark matter and dark energy.*CMB was discovered by Arno Penzias and Robert Wilson in 1965.They were working for Bell Labs in New Jersey and stumbled upon this discovery while trying to eliminate noise from their radio telescope.Their finding provided strong evidence for the Big Bang and earned them the Nobel Prize in Physics in 1978.

Hubble’s Inside The Image: Abell 2744 - NASA Goddard - astrophysics

Because of the intense gravity exerted by galaxy cluster Abell 2744,gravitational lensing,which is a curvature of space,occurs as predicted by Albert Einstein and we are able to look back in time at galaxies in the early universe about 12 billion light years away.The universe is about 13.8 billion years old.Galaxy cluster Abell 2744 also contains dark matter.

Euclid | Launch to ‘L2’

The Euclid spacecraft was launched recently on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station.Its mission is to study dark matter and dark energy,which comprise 95% of the universe's mass.Remember Einstein's calculation E=MC2,Energy equals Mass times the square of the constant,the speed of light.So it keeps the Earth,Moon and Sun behind it in order to make long exposure observations of dark matter and dark energy without interference.The radius of its orbit around L-2,Lagrange point 2,varies from 400,000 to 800,000 kilometres.
