Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding company. That is the puzzle behind a new study ...
Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.
Bronze Age rock carvings suggest communities across Europe were far more connected than previously thought, according to a new study led by the Department of Archaeology. The research compared ancient rock carvings, or "petroglyphs," ...
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the large-scale structure of ...
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA's Nancy Grace Roman Space Telescope, launching ...
In a recent viewpoint published in Nature Climate Change, six researchers from South America, Asia and Africa examine how glacier retreat in the Andes, Himalayas and other high-altitude regions is reshaping the cultural and ...
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
