“Big Life” –Habitable Exoplanet Twice Size of Earth Detected

Exoplanet Ross 128 b

 

For most of human history, the question of whether or not extraterrestrial life exists has been philosophical. It’s only in recent years that we have had the hard-science modeling tools and observational technology to address this question. A team of astronomers from the University of Cambridge have found an exoplanet more than twice the size of Earth to be potentially habitable, opening the search for life to planets significantly larger than Earth but smaller than Neptune. Using the mass, radius, and atmospheric data of the exoplanet K2-18b they determined that it’s possible for the planet to host liquid water at habitable conditions beneath its hydrogen-rich atmosphere.

Mars Insight Spacecraft –“Reveals Remnants of Red Planet’s Ancient Switched-Off Magnetic Field”

NASA Mars Insight Mission

 

Today Mars is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth’s, the result of red planet’s protective magnetic field switching off half a billion years ago. NASA scientists speculate that an impact basin deep enough to swallow Mount Everest in Valles Marineris highlights what might be the results of a ancient asteroid collision that switched off Mars magnetic field, bathing the planet in deadly radiation, and eroding its atmosphere by particles streaming from solar winds.

“The Sol 128 Event” –NASA Detects First Marsquakes Similar to Seismic Events We See on Earth

Marsquakes

 

Marsquakes were first observed on the Moon during the Apollo era. Fast forward to 26 November 2018, the NASA InSight lander successfully set down on Mars in the broad expanse of the Elysium Planitia region –the second most volcanic region after the vast equatorial volcanic plateau of Tharsis. Seventy Martian days later, the mission’s seismometer SEIS began recording the planet’s vibrations, recording 174 events until the end of September 2019. Since then, the measurements have continued leading to more than 450 observed marsquakes, or one event a day on average.

“Haunting” –‘Last & First Men’ -A Story of Humanity from Present Across Two-Billion Years

First and Last Men

 

Before his death in 2018, Icelandic director and composer Johann Jóhannsson –director of Arrival and The Theory of Everything–adapted Last and First Men, a “future history” by British science-fiction author Olaf Stapledon –a “film that straddles the border of fiction and documentary. It is a meditation on memory and failed utopia.” The story –a channeled text from the last human species–describes the history of humanity from the present across two billion years and eighteen distinct human species, of which our own is the first.

“Quirk in the Cosmos?” –‘Alpha Factor’ has Profound Implications for Physics and Life (Weekend Feature)

Early galaxies

 

Is life on earth, and perhaps the Milky Way, due to the alpha, the fine-structure constant, the coupling constant for the electromagnetic force? If alpha were just 4% bigger or smaller than it is, stars wouldn’t be able to make carbon and oxygen, which would have made it impossible for life as we know it in our Universe to exist. Research by astrophysicist John Webb on varying constants of nature will profoundly impact our view of the universe if validated.

“Weird, Inside-Out, Upside-Down Galaxy” –Surprise Hidden In the Sombrero’s Brim

Sombrero Galaxy

 

Surprising new data from NASA’s Hubble Space Telescope suggests the smooth, settled “brim” of the Sombrero galaxy’s disk may be concealing a turbulent past. Hubble’s sharpness and sensitivity resolves tens of thousands of individual stars in the Sombrero’s vast, extended halo, the region beyond a galaxy’s central portion, typically made of older stars.
