Astronomers have taken one of the deepest looks yet at Cloud-9, a candidate "dark galaxy," and found no trace of stars. The paper outlining this discovery was posted to the arXiv preprint server on Aug. 21.
A few hundred million years after the Big Bang, the first stars ignited—literally the "let there be light" moment for the universe. Now known to astronomers as Population III, or Pop III, stars, these giants were very different ...
Intense, brief flashes of radio light called fast radio bursts (FRBs) travel across billions of light-years to reach Earth, passing through a fog of matter along the way. The bursts' origins are unclear but may originate ...
The most comprehensive catalog of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe's accelerating expansion. Researchers at The University of Queensland's ...
In 2012, the Dark Energy Spectroscopic Instrument (DESI) was commissioned to measure the effect of dark energy, the mysterious force driving the expansion of the cosmos. Since then, the DESI Legacy Imaging Surveys have obtained ...
When two black holes crash together and merge, the newly formed black hole rings like a bell, sending out gravitational waves with specific frequencies that fade over time. This brief, fading pattern of waves is called ringdown, ...
Rice University researchers have used a magnetically levitated particle to search for ultraheavy dark matter, extending the hunt for some of the heaviest possible forms of the invisible matter thought to hold galaxies together. ...
Hawking radiation causes black holes to eventually evaporate. This is because particle pairs are spontaneously created near the event horizon (the position of the last ray of light that can escape the black hole's gravitational ...
Astronomers from the University of Manchester and the University of the Western Cape have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, opening a powerful new way to map ...
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
