Ah, dark matter particles, what could you be? The answer still eludes us, and astronomers keep trying new ideas to find them. A new paper in Physical Review Letters suggests that if dark matter is made of axions, we might ...

Using the MeerKAT radio telescope, an international team of astronomers has observed a Galactic globular cluster known as NGC 6522. As a result, they have discovered two new isolated pulsars in this cluster. The finding is ...
Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes.

A very rare, strange burst of extraordinarily bright light in the universe just got even stranger—thanks to the eagle-eye of the NASA/ESA Hubble Space Telescope. The phenomenon, called a Luminous Fast Blue Optical Transient ...

As the search for dark matter particles continues to yield nothing, astronomers continue to look at ways these elusive particles might be found. One general method is to look for evidence of dark matter particle decay. Although ...

Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very ...

In recent years, astronomy has seen itself in a bit of crisis: Although we know that the universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists ...

Every so often, astronomers glimpse an intense flash of radio waves from space—a flash that lasts only instants but puts out as much energy in a millisecond as the sun does in a few years. The origin of these "fast radio ...

Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave ...

On Earth, continents are likely necessary to support life. Continents "float" on top of the Earth's viscous mantle, and heat from the planet's core keeps the mantle from solidifying and locking the continents into place.
