Interview with NASA’s Chief: “We are Not Alone in the Universe, or the Multiverse” (The Galaxy Report)

ESO Observatories Chile

 

Another amazing week of news from the Cosmos: from the New York Times’ Carl Zimmer on the origins of life and how it may have evolved on other worlds to the the creeping suspicion, that there is something substantial missing from our standard model of the Universe to Albert Einstein’s demon-haunted quantum world.

“We started asking ourselves why we had not found it earlier, because it’s very extreme in its properties and very bright,” says Michael McDonald, assistant professor of physics in MIT’s Kavli Institute for Astrophysics and Space Research about the discovery of a sprawling new galaxy cluster hiding in plain sight. “It’s because we had preconceived notions of what a cluster should look like. And this didn’t conform to that, so we missed it.”

Standard Model that Describes the Fundamental Nature of the Universe – “Something Substantial is Missing”

Spiral Galaxy

 

A 2018 Hubble Space Telescope finding confirmed a nagging discrepancy about the Hubble Constant –the rate at which the Universe is expanding–showing the universe to be expanding faster now than was expected from its trajectory seen shortly after the big bang. Researchers hinted that there may be new physics to explain the inconsistency known as the ‘Hubble Tension’ “The community is really grappling with understanding the meaning of this discrepancy,” said lead researcher and Nobel Laureate Adam Riess of the Space Telescope Science Institute (STScI) and Johns Hopkins University.

Hubble Images of a Supernova -May Help Solve Known Unknowns of the Universe

 

"SN-Requiem"

 

An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from more distant galaxies is bent. This “gravitational lensing” effect has allowed University of Copenhagen astronomers to observe the same exploding star –SN Requiem–in three different places in the heavens, and may help solve the mystery of cosmic expansion and reveal the nature of dark matter and dark energy.

The Hubble Time Machine — New Ultra Deep Field With Light Equal to One-Hundred-Billion Suns

Hubble Ultra-Deep Field Revised

 

The new version of Hubble’s deep image is shown above. In dark grey you can see the new light that has been found surrounding nearly every galaxy in this field. That light corresponds to the brightness of more than one hundred billion suns. It took researchers at the Instituto de Astrofísica de Canarias almost three years to produce this deepest image of the Universe ever taken from space by recovering a large quantity of ‘lost’ light around the largest galaxies in the iconic Hubble Ultra-Deep Field (HUDF).

Inside Story of Hubble’s Return — “What Undiscovered Gems Lie Buried in Its Archives?”

 

Hubble Space Telescope

 

“The Hubble mission is meticulously storing observational data in a vast archive that is freely and internationally accessible,” Dr. Jennifer Wiseman, Hubble Space Telescope Senior Project Scientist, wrote in an email to The Daily Galaxy about the iconic space telescope being back in business and able to continue on its 32nd year of discovery, with observations restarted the afternoon of Saturday, July 17. The science instruments have returned to full operation, following recovery from a computer anomaly that suspended the telescope’s observations for more than a month.
