This Is How The Universe Changes With Every New Year That Passes

by Ethan Siegel, Forbes

With each new year that comes upon us, there are a slew of new events awaiting us not only here on Earth, but throughout the entire observable Universe. Despite all appearances that things don’t change very much, particularly on cosmic scales, our planet, the Solar System, the galaxy, and even the entire Universe all undergo significant metamorphoses that are not only detectable, but that cumulatively add up as time goes on.

Breathable atmospheres may be more common in the universe than we first thought

by Lewis Alcott and Benjamin J. W. Mills, Phys.org

The existence of habitable alien worlds has been a mainstay of popular culture for more than a century. In the 19th century, astronomers believed that Martians might be using canal-based transport links to traverse the red planet. Now, despite living in an age when scientists can study planets light years from our own solar system, most new research continues to diminish the chances of finding other worlds on which humans could live. The biggest stumbling block may be oxygen—human settlers would need a high oxygen atmosphere in which to breathe.

Astronomers Are Closing in on The Precise Moment The Universe Lit Up

by Evan Gough, ScienceAlert

A team of scientists working with the Murchison Widefield Array (WMA) radio telescope are trying to find the signal from the Universe’s first stars. Those first stars formed after the Universe’s Dark Ages.

To find their first light, the researchers are looking for the signal from neutral hydrogen, the gas that dominated the Universe after the Dark Ages.
