One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly ...
A small team of astronomers from Yunnan University, the University of Utah, New Mexico State University, and the University of St Andrews has created a new model of the Milky Way galaxy based on the results of their census ...
A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single ...
The cosmos seems to come alive with a crackling explosion of pyrotechnics in this new image from NASA's James Webb Space Telescope. Taken with Webb's MIRI (Mid-Infrared Instrument), this fiery hourglass marks the scene of ...
A pair of astrophysicists with Princeton University and the SLAC National Accelerator Laboratory found possible evidence of dark matter particles colliding. In their study, published in Physical Review Letters, Carlos Blanco ...
In humankind's ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by researchers at JILA, a joint institution ...
An international team has pioneered a "motion-picture" method for measuring the precession rate of the Milky Way's disk warp. Using a sample of Cepheid variable stars of different ages, this method allows the precession direction ...
In 2020, astronomers discovered a large hourglass-shaped structure in or near the center of our Milky Way galaxy. Dubbed "eROSITA bubbles," there have been a few different hypotheses proposed to explain their precise nature. ...
For years, astronomers have worried about how to explain why the Milky Way has fewer satellite galaxies than the standard dark matter model predicts. This is called the "missing satellites problem."
In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent ...
