Have Astronomers Detected a Cosmic String from the Dawn of the Universe?

Cosmic String



The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is one of the more intriguing  discoveries. “Part of the thrill of science is stumbling across a mystery that is not easy to solve,” said Jun-Hui Zhao of the Harvard-Smithsonian Center for Astrophysics,. “While we don’t have the answer yet, the path to finding it is fascinating.”

“We always thought of our Galaxy as an inactive galaxy, with a not so bright center,” said Magda Guglielmo from the University of Sydney about 2019 Hubble Space Telescope data showing that a titanic, expanding beam of energy sprang from close to the SgrA*, the supermassive black hole in the center of the Milky Way, 3.5 million years ago, shooting a cone-shaped burst of radiation through both poles of the Galaxy and beyond into deep space.

“Perhaps the most likely scenario for ‘life’ near a neutron star or black hole involves colonization … by robotic missions from a civilization around another nearby star,” astronomer James Cordes at Cornell University, told The Daily Galaxy. Cordes’ research focus includes neutron stars, pulsars, and the search for extraterrestrial intelligence. “Such a mission,” he notes, “would be very costly and might not be warranted given the power of remote sensing.  However, an ancient but advanced civilization might afford such a luxury.”

“Mergers of black holes with neutron stars are exceptionally rare in the Universe.  “An actual merger of a neutron star with a black hole happens, perhaps, once every million years in a galaxy.  To see one in the Milky Way, we would have to watch for a very long time,” Harald Pfeiffer, group leader in the Astrophysical and Cosmological Relativity department at Max Planck Institute for Gravitational Physics (AEI) in Potsdam, Germany, told The Daily Galaxy about recent neutron star-black hole merger of GW200105, detected by LIGO and Virgo in the past five years that have opened a completely new new way of observing the Universe.


“All the Light”– In the History of the Observable Universe

Galaxies in Milky Way


From our tiny blue dot, the universe appears inconceivably vast. In the grand cosmic scheme of things, all the light in the observable universe provides about as much illumination as a 60-watt bulb seen from 2.5 miles away, says Marco Ajello, an astrophysicist at Clemson University, who led a team in 2018 that has measured all of the starlight ever produced throughout the history of the observable universe.

“It’s mind-boggling to actually witness material orbiting a massive black hole at 30% of the speed of light,” marveled Oliver Pfuhl, a scientist at the Max Planck Institute for Extraterrestrial Physics.
