Rapid Neutron Capture: Astronomers Discover “Gold Standard” Star in Milky Way

Posted by in categories: chemistry, physics, space

A team of astronomers led by University of Michigan’s Ian Roederer and including Carnegie’s Erika Holmbeck have identified the widest range of elements yet observed in a star beyond our own Sun. Their findings will be published in The Astrophysical Journal Supplement Series.

The researchers identified 65 elements in the star, which is called HD 222925. Of these, 42 are from the bottom of the periodic table. Their identification will help astronomers better understand rapid neutron capture process — one of the main methods by which the universe’s heavy elements were created.

“To the best of my knowledge, that’s a record for any object beyond our Solar System. And what makes this star so unique is that it has a very high relative proportion of the elements listed along the bottom two-thirds of the periodic table. We even detected gold,” explained Roederer, a former Carnegie postdoc. “These elements were made by the rapid neutron capture process. That’s really the thing we’re trying to study: the physics in understanding how, where and when those elements were made.”

We believe Mars may once have had oceans and sky, but lost them from a lack of a magnetosphere. How does this happen, and how can we create a magnetosphere for Mars so we can terraform and live on it?

NASA InSight Still Hunting Marsquakes as Power Runs Down (News Audio + Visuals)

Posted by in categories: energy, space

In November 2018, NASA InSight landed in the Elysium Planitia region of Mars with the goal of studying the planet’s deep interior for the first time by using seismic signals to learn more about the properties of the planet’s crust, mantle, and core. Join us live at 11 a.m. PT (2 p.m. ET/1800 UTC) on May 17 as agency leadership and mission team members highlight the spacecraft’s science accomplishments, share details on its power situation, and discuss its future.

Mysterious invisible walls may have been discovered in outer space

Posted by in categories: particle physics, space

“Scientists suspect that a ”fifth force” may be at work in space. This force, which they believe is mediated by a hypothetical particle called a symmetron is responsible for creating invisible walls in space.

The walls aren’t necessarily like the walls of a room. Instead, they are more like barriers. And, they could help explain an intriguing part of space that has left astronomers scratching their heads for quite a while.

Astronomers might’ve discovered why Saturn’s moon Titan looks like Earth

Posted by in category: space

Titan looks suspiciously like our own planet when you observe it. However, Saturn’s moon and our own Earth couldn’t be any more different. Where landscapes are made of silicate-based sediments on Earth, many believe Titan’s landscapes are made of solid organic compounds. As such, they should be much more fragile than Earth’s. A new study may have figured out how the landscapes on Titan came to be.
