Compact, reflective, easy-to-manufacture mirrors are a critical component for advancing astronomical technology in space. Mirrors are a key component in most telescopes, though they are notoriously hard to manufacture with the necessary precision, especially at large scales. A new paper posted to the arXiv preprint server from researchers in the U.K. uses additive manufacturing to […] The exciting discovery of an extremely rare quadruple star system could significantly advance our understanding of brown dwarfs, astronomers say. These mysterious objects are too big to be considered a planet but also too small to be a star because they lack the mass to keep fusing atoms and blossom into fully-fledged suns. Go to […] According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense “soup” composed of freely moving quarks and gluons. This state of matter is known as quark-gluon plasma (QGP). Finding definitive evidence for the existence of QGP is crucial for […] As explained by Tesla himself, the Earth is “…like a charged metal ball moving through space”, which creates the enormous, rapidly varying electrostatic forces which diminish in intensity with the square of the distance from Earth, just like gravity. Since the direction of propagation radiates from the earth, the so-called force of gravity is […] Astronomers from Seoul National University, South Korea and elsewhere report the detection of 62 new luminous quasars as part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS). The discovery was detailed in a research paper published August 8 on the arXiv preprint server. Go to Source Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion of a star. Because supernovae are sudden and unpredictable, they have long been difficult to study, but today, thanks to […] An asteroid wiped out a civilization like ours 13,000 years ago—and it could happen again in 2030 An extremely advanced ancient civilization—that flourished during the Ice Age—was wiped out from the surface of the planet some 13,000 years ago due to a massive comet strike, and the ancients left us a warning of future […] The officers were responding to a domestic disturbance call in Tremonton; after the officers were shot, bystanders persuaded the man to put down his weapon Go to Source New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, coronal mass ejections and other space weather phenomena. The data was captured by NASA’s Parker Solar Probe (PSP), which is the only spacecraft to have flown through the […] A new study from the University of Nottingham has explored the use of fuel-free spacecraft propulsion systems and how they could be used in future space missions. Go to Source In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the moon by the time China plans to land the […] Answers to some of cosmology’s most pressing questions are obscured by simple dust. It concerns the Cosmic Noon, a period of time that began around 2 billion years after the Big Bang, when nearly all galaxies experienced a burst of growth and rapid star formation. Go to Source This NASA/ESA Hubble Space Telescope image zooms in on the feathery spiral arms of the galaxy NGC 45, which lies just 22 million light-years away in the constellation Cetus (the Whale). Go to Source A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the main asteroid belt between the orbits of Mars and Jupiter. Go to Source A team of Johns Hopkins engineers has developed a new, more powerful method to observe molecular vibrations, an advance that could have far-reaching implications for early disease detection.
