Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they are predicted to produce gravitational waves, ripples in the fabric of spacetime that travel at the speed of light. Go to Source […] To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked up by different telescopes that are at different locations, then reconstructing images using computational techniques. Go to Source […] NASA is set to begin fueling 700,000 gallons of cryogenic propellant on the Space Launch System rocket at Kennedy Space Center on Thursday as it moves ahead with a test countdown of the Artemis II mission. Go to Source A total lunar eclipse will cross the skies over the contiguous United States on Tuesday, March 3, turning the moon a deep reddish color in what’s commonly called a “blood moon.” Go to Source It will be business as usual for SpaceX when it tries to send up a rocket from the Space Coast Thursday night, but not so much for when the rocket comes back down. Go to Source On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a cosmic ray detector, was designed to measure the radiation environment in Earth orbit. Though its final transmission was in May 1958, it continued to revolve around Earth more than 58,000 times. As those looping orbits […] Viracocha, the sun god, and supreme creator was sacred to the Inca Empire, as was gold. However, gold had no material value but represented Viracocha’s blood and the sweat of the sun. For the Inca and pre-Inca cultures, Viracocha was a supreme creator who was non-binary, neither male nor female. Believers rarely used Viracocha’s […] Michael Black jammed the gun with his hand and other bystanders put the shooter in a chokehold, subduing the suspect before he died from a self-inflicted gunshot, authorities said Go to Source Scientists at Microsoft Research in the United States have demonstrated a system called Silica for writing and reading information in ordinary pieces of glass which can store two million books’ worth of data in a thin, palm-sized square. Go to Source An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the effects of dilute nitridation. Go to Source NASA’s new boss blasted Boeing and the space agency Thursday for Starliner’s botched flight that left two astronauts stuck for months at the International Space Station. Go to Source Imagine a material cracking—now imagine what happens if there are small inclusions in the material. Do they create an obstacle course for the crack to navigate, slowing it down? Or do they act as weak points, helping the crack spread faster? Go to Source New research by Southwest Research Institute (SwRI) and the National Science Foundation’s National Center for Atmospheric Research (NSF-NCAR) has developed a new tool providing a first step toward the ability to forecast space weather weeks in advance, instead of just hours. This advance warning could allow agencies and industries to mitigate impacts to GPS, power […] Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced “combs” of laser light on a photonic chip, a breakthrough that could miniaturize optical platforms like spectroscopic sensors or communication systems. Go to Source Researchers have developed a unified theory of microcavity OLEDs, guiding the design of more efficient and sustainable devices. The work reveals a surprising trade-off: squeezing light too tightly inside OLEDs can actually reduce performance, and maximum efficiency is achieved through a delicate balance of material and cavity parameters. The findings are published in the journal […] |
