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.

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.

Chatgpt designs a robot      (via sciencedaily.com)     Original source 

Poems, essays and even books -- is there anything the OpenAI platform ChatGPT can't handle? These new AI developments have inspired researchers to dig a little deeper: For instance, can ChatGPT also design a robot? And is this a good thing for the design process, or are there risks?

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.

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.

Weigh a quasar's galaxy with precision      (via sciencedaily.com)     Original source 

Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this summer.

Eventually everything will evaporate, not only black holes      (via sciencedaily.com)     Original source 

New theoretical research has shown that Stephen Hawking was likely right about black holes, although not completely. Due to Hawking radiation, black holes will eventually evaporate, but the event horizon is not as crucial as had been believed. Gravity and the curvature of spacetime cause this radiation too. This means that all large objects in the universe, like the remnants of stars, will eventually evaporate.

Mysterious dashes revealed in Milky Way's center      (via sciencedaily.com)     Original source 

In the early 1980s, astronomers discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our galaxy's central supermassive black hole. Now, astronomers have discovered a new population of filaments -- but these threads are much shorter and lie horizontally or radially, spreading out like spokes on a wheel from the black hole.

Astrophysicists confirm the faintest galaxy ever seen in the early universe      (via sciencedaily.com)     Original source 

After the Big Bang, the universe expanded and cooled sufficiently for hydrogen atoms to form. In the absence of light from the first stars and galaxies, the universe entered a period known as the cosmic dark ages. The first stars and galaxies appeared several hundred million years later and began burning away the hydrogen fog left over from the Big Bang, rendering the universe transparent, like it is today. Researchers have now confirmed the existence of a distant, faint galaxy typical of those whose light burned through the hydrogen atoms; the finding should help them understand how the cosmic dark ages ended.
