Hubble Reaches New Milestone in Mystery of Universe's Expansion Rate
Sunday, 22 May 2022 10:02Completing a nearly 30-year marathon, NASA's Hubble Space Telescope has calibrated more than 40 "milepost markers" of space and time to help scientists precisely measure the expansion rate of the universe - a quest with a plot twist. Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaitre. In 1998, this led to the di
Unraveling a perplexing explosive process that occurs throughout the universe
Sunday, 22 May 2022 10:02Mysterious fast radio bursts release as much energy in one second as the Sun pours out in a year and are among the most puzzling phenomena in the universe. Now researchers at Princeton University, the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and the SLAC National Accelerator Laboratory have simulated and proposed a cost-effective experiment to produce and obse
New calculations of Solar spectrum resolve decade-long controversy about the Sun's chemical composition
Sunday, 22 May 2022 10:02Astronomers have resolved the decade-long solar abundance crisis: the conflict between the internal structure of the Sun as determined from solar oscillations (helioseismology) and the structure derived from the fundamental theory of stellar evolution, which in turn relies on measurements of the present-day Sun's chemical composition. New calculations of the physics of the Sun's atmosphere yield
Ghostly 'mirror world' might be cause of cosmic controversy
Sunday, 22 May 2022 10:02New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today - the Hubble constant problem. The Hubble constant is the rate of expansion of the universe today. Predictions for this rate - from cosmology's standard model - are significantly slower than the rate found by our most
NASA's HyTEC to Help Jets Burn Less Fuel
Sunday, 22 May 2022 10:02Cleveland OH (SPX) May 20, 2022 What if we told you we could reimagine the way a jet engine works to generate the same amount of power using less fuel? Our aeronautical innovators are designing a new jet engine that, compared to current engines, will produce the same thrust and even look the same on the outside, but is more fuel-efficient. HyTEC, or Hybrid Thermally Efficient Core,
The missing piece to faster, cheaper and more accurate 3D mapping
Sunday, 22 May 2022 10:02Three-dimensional (3D) mapping is a very useful tool, such as for monitoring construction sites, tracking the effects of climate change on ecosystems and verifying the safety of roads and bridges. However, the technology currently used to automate the mapping process is limited, making it a long and costly endeavor. "Switzerland is currently mapping its entire landscape using airborne lase
Satellites and drones can help save pollinators
Sunday, 22 May 2022 10:02Satellites and drones can provide key information to protect pollinators, researchers say. Their study examines new ways of using these technologies to track the availability of flowers, and says this could be combined with behavioural studies to see the world through the eyes of insects. The flowers available to insects vary from day to day and place to place, and human activity is
Terran Orbital announces DARPA award
Sunday, 22 May 2022 01:00Terran Orbital Corporation (NYSE: LLAP), a global leader in small satellite solutions, primarily serving the United States aerospace and defense industry, has announced that its subsidiary, PredaSAR Corporation, received a contract award from the Defense Advanced Research Projects Agency (DARPA) under an Other Transaction Authority for Prototype Agreement. Specific terms of the Agreement were no

Boeing docks crew capsule to space station in test do-over
Saturday, 21 May 2022 05:10Boeing's Starliner spaceship docks with ISS in high-stakes test mission
Saturday, 21 May 2022 01:24Boeing's Starliner capsule docked with the International Space Station Friday, a major milestone in a high-stakes uncrewed test flight as the US aerospace giant seeks to restore its reputation following past failures. The spaceship made contact at 8:28 pm Eastern time (0028 GMT Saturday), a little over 24 hours after it blasted off from the Kennedy Space Center in Florida on a mission to pro

Where do "Hawaiian box jellies" come from?
Friday, 20 May 2022 19:23An insightful cross-disciplinary team of University of Hawai'i (UH) at Mānoa researchers, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature "Hawaiian box jellyfish" (Alatina alata) to swim to leeward O'ahu shores to spawn.
Led by Angel Yanagihara, associate research professor at the UH Mānoa School of Ocean and Earth Science and Technology (SOEST) and the John A. Burns School of Medicine, researchers at the UH at Mānoa have been carefully tracking local box jellies for over 20 years. While the monthly shoreline aggregations are understood to occur like clockwork 8-10 days after each full moon, with jelly forecasts included on the local news, mysteries have remained: Why are they appearing at this particular part of the lunar cycle? Where do these box jellies come from and where are they found the rest of the lunar cycle? Why has this become a monthly problem in only the last 30 years?
Boeing's Starliner approaching ISS in high-stakes test mission
Friday, 20 May 2022 16:18Boeing's Starliner capsule was preparing to dock with the International Space Station Friday, in a high-stakes uncrewed test flight key to reviving the US aerospace giant's reputation after a series of failures.
The spaceship blasted off from the Kennedy Space Center in Florida on Thursday evening, and is now set to rendezvous with the ISS at 7:10 pm Eastern Time (2310 GMT), as part of a mission to prove it is capable of providing safe rides for NASA astronauts.
