The rotation of stars in galaxies such as the Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact, stars in the middle and outer regions of galaxies ...
Astronomers have discovered an asteroid looping through the inner solar system on an exotic orbit. The unusual object is among the first asteroids ever found whose orbit is confined almost entirely within the orbit of Venus. ...
A new and extremely sensitive method of measuring ultrasound could revolutionise everything from medical devices to unmanned vehicles.
A Northwestern University-led international team is getting closer to understanding the mysteriously bright object that burst in the northern sky this summer.
ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The "PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars.
Gazing across 300 million light-years into a monstrous city of galaxies, astronomers have used NASA's Hubble Space Telescope to do a comprehensive census of some of its most diminutive members: a whopping 22,426 globular ...
Forget those shepherding moons. Gravity and the odd shapes of asteroid Chariklo and dwarf planet Haumea—small objects deep in our solar system—can be credited for forming and maintaining their own rings, according new ...
As an astrophysicist, probably the most common question I get asked is: "Are we alone in the universe and do aliens exist?"
A pair of Columbia University astronomers using NASA's Hubble Space Telescope and Kepler Space Telescope have assembled compelling evidence for the existence of a moon orbiting a gas-giant planet 8,000 light-years away.
Topology is a global aspect of materials, leading to fundamental new properties for compounds with large relativistic effects. The incorporation of heavy elements gives rise to non-trivial topological phases of matter, such ...
