Scientists spot more Milky Way-like galaxies in early universe      (via sciencedaily.com)     Original source 

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe's origin story as previously told using data from NASA's Hubble Space Telescope.

Origins of fast radio bursts come into focus through polarized light      (via sciencedaily.com)     Original source 

What scientists previously thought about where Fast Radio Bursts (FRBs) come from is just the tip of the iceberg. A new study details the properties of polarized light from 128 non-repeating FRBs and reveals mysterious cosmic explosions that originated in far-away galaxies, similar to our own Milky Way.

How did a satellite galaxy of the Milky Way come to be?      (via sciencedaily.com)     Original source 

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.

Looking for a new battery platform? Focus on the essentials      (via sciencedaily.com)     Original source 

In facing life's many challenges, we often opt for complex approaches to finding solutions. Yet, upon closer examination, the answers are often simpler than we expect, rooted in the core "essence" of the issue. This approach was demonstrated by a research team in their publication on addressing the inherent issues of solid-state batteries.

Lone Star State: Tracking a low-mass star as it speeds across the Milky Way      (via sciencedaily.com)     Original source 

Astronomers have discovered a rare hypervelocity L subdwarf star racing through the Milky Way. More remarkably, this star may be on a trajectory that causes it to leave the Milky Way altogether.

NASA's Webb opens new window on supernova science      (via sciencedaily.com)     Original source 

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

Researchers engineer new approach for controlling thermal emission      (via sciencedaily.com)     Original source 

If a material absorbs light, it will heat up. That heat must go somewhere, and the ability to control where and how much heat is emitted can protect or even hide such devices as satellites. An international team of researchers has published a novel method for controlling this thermal emission in Science.

Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments      (via sciencedaily.com)     Original source 

Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who screens them for potentially hazardous compounds.

Hubble finds surprises around a star that erupted 40 years ago      (via sciencedaily.com)     Original source 

Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst onto the scene as a bright and long-lived nova. A nova is a star that suddenly increases its brightness tremendously and then fades away to its former obscurity, usually in a few months or years.

Galactic bloodlines: Many nearby star clusters originate from only three 'families'      (via sciencedaily.com)     Original source 

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of giant gas structures in galaxies like our Milky Way.

Scientists 'read' the messages in chemical clues left by coral reef inhabitants      (via sciencedaily.com)     Original source 

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
