Natural phenomenon of Manhattanhenge expected to draw crowds

Thanks to a natural phenomenon, it's not all about the plays and celebrity sightings in New York City. When the sun lines up with the Manhattan street grid before setting, the city gets bathed in radiance.

Black holes come to the big screen

The new movie "Interstellar" explores a longstanding fascination, but UA astrophysicists are using cutting-edge technology to go one better. They're working on how to take pictures of the black hole at the center of the galaxy.

Astrophysicists ask public to rank sunspots

'Sunspots' and 'solar storms' are the feature of an ambitious project being launched internationally by astrophysicists at Trinity College Dublin today. Members of the public will work as part of a global team to better understand ...

HADES searches for dark matter

Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon ...

A turbulent birth for stars in merging galaxies

( —Using state of the art computer simulations, a team of French astrophysicists have for the first time explained a long standing mystery: why surges of star formation (so called 'starbursts') take place when ...

Astrophysics (Greek: Astro - meaning "star", and Greek: physisφύσις - meaning "nature") is the branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior. Among the objects studied are galaxies, stars, planets, exoplanets, the interstellar medium and the cosmic microwave background. Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. The study of cosmology addresses questions of astrophysics at scales much larger than the size of particular gravitationally-bound objects in the universe.

Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics. In practice, modern astronomical research involves a substantial amount of physics. The name of a university's department ("astrophysics" or "astronomy") often has to do more with the department's history than with the contents of the programs. Astrophysics can be studied at the bachelors, masters, and Ph.D. levels in aerospace engineering, physics, or astronomy departments at many universities.
