There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and resolving this could reveal new physics. Astronomers constantly seek new ways

China routinely sends astronauts to and from its space station Tiangong. A crew capsule is about to undock from the station and return to Earth, but there’s nothing routine about
High up in Earth’s orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to
Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention of scientists. This planet orbits the star within the “Goldilocks zone”—a
In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains
“Why are we here?” is humanity’s most fundamental and persistent question. Tracing the origins of the elements is a direct attempt to answer this at its deepest level. We know
An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a “razor-thin” string of galaxies embedded in a giant spinning cosmic
There’s been a lot of speculation recently about interstellar visitor 3I/ATLAS—much of which is probably caused by low-quality data given that we have to observe it from either Earth, or
Chile’s Atacama Desert is one of the darkest spots on Earth, a crown jewel for astronomers who flock to study the origins of the universe in this inhospitable desert along
Observations with the instrument SPHERE at ESO’s Very Large Telescope have produced an unprecedented gallery of “debris disks” in exoplanetary systems.
