Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say. Their theory is a potential solution to the ‘Hubble tension’ and could help confirm the true age of our universe,Continue Reading
A team of solar physicists has released a new study shedding light on the fine-scale structure of the Sun’s surface. Using the unparalleled power of the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope, built and operated by the NSF National Solar Observatory (NSO) on Maui, scientists haveContinue Reading
A team of researchers from Würzburg has for the first time experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. Scientists have long known that electrons can form vortices in quantum materials. What’s new is the proof that these tiny particlesContinue Reading
Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today. “When it comes to producing ultraviolet light, these small galaxies punch well above their weight,”Continue Reading
Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres. Knowing what happensContinue Reading
University of Central Florida (UCF) scientists and their collaborators discovered new insights into the formation of distant icy objects in space beyond Neptune, offering a deeper understanding of our solar system’s formation and growth. Using the James Webb Space Telescope (JWST), scientists analyzed far-away bodies — known as Trans-Neptunian ObjectsContinue Reading
Every year, Earth gets a bit bigger. Thousands of metric tons of space dust fall from the sky, while about 50 tons per year of meteorites crash land somewhere on the surface. Since the 1960s, space junk has also occasionally returned to Earth, falling from a hazy sphere of trashContinue Reading
University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe’s gravitational wave background — the constant flow of waves that churn through the cosmos, warping the very fabric of space and time. The research, published in The Astrophysical Journal Letters, could one day helpContinue Reading
The Health Care Select Sector SPDR Fund ETF (NYSEARCA:XLV), tracking the healthcare companies under S&P 500, rose 0.11% in the second quarter of 2024, lagging behind the broader S&P 500 index which rose 4.30%. Insulet (PODD) saw the biggest growth in the S&P 500 healthcare index, rising about 25% asContinue Reading
Walgreen’s Boots Alliance (NASDAQ:WBA) shares are set to open lower for a fifth consecutive day as the company’s decision to close a “substantial” number of U.S. stores continues to weigh on the stock. The company was subsequently hit with a wave of price target adjustments, the latest from BofA Securities,Continue Reading
