Rise of Oxygen –An Evolutionary Moment that Shaped Our Planet

 

Rise of Oxygen on Earth

 

“Oxygen flooded into the atmosphere as a pollutant, even a poison, until natural selection shaped living things to thrive on the stuff and, indeed, suffocate without it,” wrote evolutionary biologist, Richard Dawkins, in The Greatest Show on Earth: The Evidence for Evolution.

Will We Actually Be Able to Detect a Signal from an Alien Intelligence? (Weekend Feature)

Alien Signal

 

British physicist Stephen Wolfram believes extraterrestrial intelligent life is inevitable, but with a caveat. Although intelligent life is inevitable, we will never find it. Wolfram says that  in order to compress more and more information into our communication signals – be they mobile phone conversations or computers – we remove all redundancy or pattern. If anything in a signal repeats, then it can be deleted. But this process of removing any pattern from a signal makes the signal look more and more random – in fact, pretty much like the random radio “noise” that rains down on Earth coming from stars and interstellar gas clouds.

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.

Monster Galaxies at the Dawn of Time

 

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.

“Judging by the history of life on Earth and the possible futures we think we can see coming, it is indeed quite possible that most, or effectively all, civilizations in the universe are comprised of machine intelligences,” wrote astrobiologist David Grinspoon in an email to The Daily Galaxy
