NASA's Webb confirms its first exoplanet      (via sciencedaily.com) 

Researchers confirmed an exoplanet, a planet that orbits another star, using NASA's James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth's diameter.

Scientists study life origins by simulating a cosmic evolution      (via sciencedaily.com) 

Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals. Because of amino acids' relationship to living things scientists are eager to understand the origins of these molecules. After all, amino acids may have helped spawn life on Earth after being delivered here about 4 billion years ago by pieces of asteroids or comets.

The seven-year photobomb: Distant star's dimming was likely a 'dusty' companion getting in the way, astronomers say      (via sciencedaily.com) 

Astronomers were on the lookout for 'stars behaving strangely' when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn't changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, 'dusty' stellar companion.

Planetary system's second Earth-size world discovered      (via sciencedaily.com) 

Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.

Scientists find evidence for magnetic reconnection between Ganymede and Jupiter      (via sciencedaily.com) 

In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.

Hydrogen masers reveal new secrets of a massive star      (via sciencedaily.com) 

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space.

Experimentalists: Sorry, no oxygen required to make these minerals on Mars      (via sciencedaily.com) 

When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago. But a new experimental study upends this view. Scientists discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen.

New study models the transmission of foreshock waves towards Earth      (via sciencedaily.com) 

As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.

Scientists discover a novel photophysical mechanism that has achieved record-breaking efficiency for organic photovoltaics      (via sciencedaily.com) 

Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.
