Gemini North back on sky with dazzling image of supernova in the Pinwheel Galaxy
The Gemini North telescope, one half of the International Gemini Observatory operated by NSF's NOIRLab, has returned from a seven-month hiatus literally with a bang, as it has captured the spectacular aftermath of a supernova, a massive star that exp.....»»
Researchers discover chemical evidence for pair-instability supernova from a very massive first star
The first stars illuminated the universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos......»»

NASA looks back at 50 years of gamma-ray burst science
Fifty years ago, on June 1, 1973, astronomers around the world were introduced to a powerful and perplexing new phenomenon called GRBs (gamma-ray bursts). Today sensors on orbiting satellites like NASA's Swift and Fermi missions detect a GRB somewher.....»»
Researchers find a way to reduce the overheating of semiconductor devices
The demand to shrink the size of semiconductors coupled with the problem of the heat generated at the hot spots of the devices not being effectively dispersed has negatively affected the reliability and durability of modern devices. Existing thermal.....»»
1c DRAM key to determining memory market leadership in 2024
Samsung, SK Hynix, and Micron are all technically capable of mass producing the fifth-generation 10nm 1b or 1β (Beta) DRAM, but it is predicted that the sixth-generation 10nm 1c or 1γ (Gamma) DRAM will become the key to determining which o.....»»

The huge watery cloud spurting from Enceladus could carry the ingredients for life farther into space than previously known.....»»
For the first time, astronomers have detected a radio signal from the massive explosion of a dying white dwarf
When stars like our sun die, they tend to go out with a whimper and not a bang—unless they happen to be part of a binary (two) star system that could give rise to a supernova explosion......»»
Micron to produce EUV DRAM memory in Japan
Micron Technology has announced that it will introduce extreme ultraviolet (EUV) technology to Japan, utilizing this advanced patterning technology to produce its next generation of DRAM, the 1-gamma node......»»
Radio signal reveals supernova origin
In the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the explod.....»»
