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.

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.

NIRISS instrument on Webb maps an ultra-hot Jupiter's atmosphere      (via sciencedaily.com)     Original source 

There's an intriguing exoplanet out there -- 400 light-years out there -- that is so tantalizing that astronomers have been studying it since its discovery in 2009. One orbit for WASP-18 b around its star that is slightly larger than our Sun takes just 23 hours. There is nothing like it in our Solar System. A new study about this exoplanet, an ultra-hot gas giant 10 times more massive than Jupiter.

Quest for alien signals in the heart of the Milky Way takes off      (via sciencedaily.com)     Original source 

A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.

X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration      (via sciencedaily.com)     Original source 

Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.

Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'      (via sciencedaily.com)     Original source 

A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
