Astronomers discover supernova explosion through rare 'cosmic magnifying glasses'      (via sciencedaily.com)     Original source 

An international team of scientists recently discovered an exceptionally rare gravitationally lensed supernova, which the team named 'SN Zwicky.' Located more than 4 billion light years away, the supernova was magnified nearly 25 times by a foreground galaxy acting as a lens. The discovery presents a unique opportunity for astronomers to learn more about the inner cores of galaxies, dark matter and the mechanics behind universe expansion.

Why certain fish are left off the hook      (via sciencedaily.com)     Original source 

A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.

When water temperatures change, the molecular motors of cephalopods do too      (via sciencedaily.com)     Original source 

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.

Elusive planets play 'hide and seek' with CHEOPS      (via sciencedaily.com)     Original source 

Astronomers have clearly identified the existence of four new exoplanets. The four mini-Neptunes are smaller and cooler, and more difficult to find than the so-called Hot Jupiter exoplanets which have been found in abundance.

Long missions, frequent travel take a toll on astronauts' brains      (via sciencedaily.com)     Original source 

A study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.

New study identifies mechanism driving the sun's fast wind      (via sciencedaily.com)     Original source 

Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun's surface is powerful enough to drive the fast solar wind, which is made up of ionized particles -- called plasma -- that flow outward from the sun.

Whales not to be counted on as 'climate savers'      (via sciencedaily.com)     Original source 

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.

Webb Space Telescope detects universe's most distant complex organic molecules      (via sciencedaily.com)     Original source 

Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe.

NASA's Webb Space Telescope peers behind bars      (via sciencedaily.com)     Original source 

A delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image -- a composite from two of Webb's instruments.

Dying stars' cocoons could be new source of gravitational waves      (via sciencedaily.com)     Original source 

Although astrophysicists theoretically should be able to detect gravitational waves from a single, non-binary source, they have yet to uncover these elusive signals. Now researchers suggest looking at a new, unexpected and entirely unexplored place: The turbulent, energetic cocoons of debris that surround dying massive stars.

Early universe crackled with bursts of star formation, Webb shows      (via sciencedaily.com)     Original source 

Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA's James Webb Space Telescope is already providing new insights into this question. One of the largest programs in Webb's first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will devote about 32 days of telescope time to uncover and characterize faint, distant galaxies. While the data is still coming in, JADES already has discovered hundreds of galaxies that existed when the universe was less than 600 million years old. The team also has identified galaxies sparkling with a multitude of young, hot stars.
