Is Something Missing from the Standard Model of the Universe? (Holiday Feature)

The Universe

 

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.

Did Water Exist in the Galaxies of the Early Cosmos? (Holiday Feature)

 

Early Galaxy SPT0311-58

 

It has been said that to understand water is to understand the cosmos and life itself. 2021 observations from the Atacama Large Millimeter/submillimeter Array (ALMA)  detected this primal substance in the most massive galaxy in the early Universe.

Galaxy GN-z11

 

“We’ve taken a major step back in time, beyond what we’d ever expected to be able to do with Hubble. We see GN-z11 at a time when the universe was only three percent of its current age,”  observed Pascal Oesch at the University of Geneva and head of the Galaxy Build-Up at Cosmic Dawn team about the discovery of a 13.4 billion-years -old galaxy. It’s mind-boggling by comparison to think that Earth is only 4.5 billion years old.

Was the First Planet Beyond the Milky Way Discovered, or Something Even More Exotic? (Weekend Feature)

 

Whirlpool Galaxy

 

In 2019 the Nobel Prize in Physics was awarded to Michel Mayor and Didier Queloz for pioneering a new field in astronomy with the discovery of the first planet beyond our solar system, 51 Pegasi b. Since the discovery in 1991, over 4,000 exoplanets have been found in our home galaxy. “We answered a very old question,” Mayor said, which was debated by philosophers since the ancient Greeks: “are there other worlds in the Universe?”

Eruption from an Object With a Magnetic Field One-Thousand-Trillion Times Stronger than Our Sun’s

 

Magnetar

 

So far, we have had only close calls from gamma ray explosions so large, scientists have suggested, that if they occurred within our solar neighborhood (less than 1,000 light years) they could potentially trigger mass extinctions on Earth.
