Astronomers spot stars in the most distant galaxies for the first time
Since it launched on December 25th, 2021, the James Webb Space Telescope (JWST) has taken the sharpest and most detailed images of the universe, surpassing even its predecessor, the venerable Hubble Space Telescope. But what is especially exciting ar.....»»
Single-pulse behavior of rotating radio transient PSR J0628+0909 explored with FAST
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have inspected single-pulse behavior of a rotating radio transient (RRAT) known as PSR J0628+0909. Results of the study, published November 22 in Monthly Noti.....»»
Astronomers make most extensive study yet of young stars" magnetic activity
Astronomers have made the most extensive study yet of how magnetically active stars are when they are young. This gives scientists a window into how X-rays from stars like the sun, but billions of years younger, could partially or completely evaporat.....»»
High-speed, high-sensitivity terahertz detection using graphene transistor
On the electromagnetic spectrum, which comprises everything from radio waves to X-rays and gamma rays, there exists a deadzone where conventional electronic devices can hardly operate. This deadzone is occupied by terahertz waves......»»
Discovering a rare red spiral galaxy population from the early universe with the James Webb Space Telescope
Spiral galaxies represent one of the most spectacular features in our universe. Among them, spiral galaxies in the distant universe contain significant information about their origin and evolution. However, we have had a limited understanding of thes.....»»
NASA"s Webb reaches new milestone in quest for distant galaxies
An international team of astronomers has used data from NASA's James Webb Space Telescope to report the discovery of the earliest galaxies confirmed to date. The light from these galaxies has taken more than 13.4 billion years to reach us, as these g.....»»
Radiation shielding: MAPbI3/epoxy composites exhibit superior performance
Gamma rays can cause serious damage to the human body. Therefore, it is very important to develop gamma-ray shielding materials with excellent radiation shielding properties. To reach this goal, scientists in China invented a lightweight perovskite/e.....»»
"Phantoms" from beyond the moon could provide valuable data on cosmic radiation doses
The Orion spacecraft on the Artemis I mission is carrying, as part of the MARE experiment, two human "phantoms" equipped with numerous cosmic rays detectors. The information gathered by the detectors will for the first time verify the knowledge, cruc.....»»
Tiny, hidden galaxy provides a peek into the past
Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years ac.....»»
Transport of air masses in connection with El Niño decoded
The El Niño phenomenon influences the weather in distant regions, as far away as the U.S., India or the Mediterranean region. But how exactly these so-called teleconnections actually work has not yet been clarified completely......»»
Apple Watch could get more hands-free tilt controls in future watchOS update
The Apple Watch could include more gestures similar to Raise to Speak in the future, after the revelation Apple has explored the possibility of producing more hands-free ways to interact with wearable devices and other hardware.Apple introduced Raise.....»»

Cosmic ray counts hidden in spacecraft data highlight influence of solar cycle at Mars and Venus
Measurements by ESA's long-serving twin missions, Mars Express and Venus Express, have captured the dance between the intensity of high-energy cosmic rays and the influence of the sun's activity across our inner solar system......»»
Research inspects a distant gamma-ray emitting blazar
An international team of astronomers has performed a long-term multiwavelength study of a distant gamma-ray emitting blazar known as 1ES 0647+250. Results of the research, published November 23 on arXiv.org, yield important insights into the long-ter.....»»
New monochromator optics for tender X-rays
A climate-neutral energy supply requires a wide variety of materials for energy conversion processes, for example catalytically active materials and new electrodes for batteries. Many of these materials have nanostructures that increase their functio.....»»
Most distant detection of a black hole swallowing a star
Earlier this year, the European Southern Observatory's Very Large Telescope (ESO's VLT) was alerted after an unusual source of visible light had been detected by a survey telescope. The VLT, together with other telescopes, was swiftly repositioned to.....»»
