Astrophysics is a branch of astronomy that explores the physical properties of the cosmos and its composition. Astrophysicist study a broad range of topics, from the tiniest particles of matter and the forces that join them together to the grandest of celestial structures. In essence, astrophysics extends the physics and chemistry we experience directly here on Earth into the vastness of space. It is both an observational and theoretical science. To probe the universe's past, present and future, astrophysicists have built some of the most complex and precise machine's in the world, including terrestrial and space-based telescopes tuned to various wavelengths, and continue to push the limits of technology. The Big Bang Model is a broadly accepted theory of how the universe began and evolved, and astrophysicists are continuing to test and refine it. 

Will a New Discovery Fast-track Our Understanding of the Origins of Galaxies and Gargantuan Black Holes?

Mar 07, 2017

The Kavli Foundation spoke with three astrophysicists—Roberto Maiolino, Linhua Jiang and Marta Volonteri—about how a record haul of new, ultra-distant quasars will transform what we know about the early universe.

Transiting exoplanet

A newfound alien world orbiting a small, nearby star could be one of the first exoplanets scientists get to investigate in detail. Two of the astronomers who made the discovery—MKI's Zachory Berta-Thompson and Elisabeth Newton–discuss what they might encounter there with Rory Barnes from the University of Washington.

Spotlight Live: Searching for Alien Life wth a "Super-Hubble" Space Telescope (Transcript)

Nov 05, 2015
Milky Way

On October 6, The Kavli Foundation hosted a Google+ Hangout to learn more about proposed High Definition Space Telescope, a kind of "Super Hubble" that could launch in the 2030s. We spoke with two of the proponents: Julianne Dalcanton of the University of Washington and Marc Postman of the Space Telescope Science Institute. This is a transcript of that discussion.
