Physics of the Cosmos

Program Home Page  PCOS Newsletter

Our quest to understand how the universe works starts with the study of the very basic building blocks of our existence - matter, energy, space, and time - and how they behave under the extreme physical conditions that characterize the infant and evolving Universe. The Physics of the Cosmos (PCOS) program incorporates cosmology, high-energy astrophysics, and fundamental physics projects aimed at addressing directly central questions about the nature of complex astrophysical phenomena such as black holes, neutron stars, dark energy, and gravitational waves. By utilizing a fleet of space-based missions operating across the whole electromagnetic spectrum, PCOS ultimate, overarching goal is to learn about the origin and ultimate destiny of the cosmos.

DivisionNameLaunch DatePhase
Astrophysics Chandra
Chandra explores the hot turbulent regions in space with images 25 times sharper than previous x-ray pictures. Chandra is performing detailed studies of black holes, supernovas, and dark matter, to increase our understanding of the origin, evolution, and destiny of ...

Astrophysics IXO
The International X-ray Observatory (IXO) was an X-ray astronomy mission with joint participation from NASA, the European Space Agency (ESA), and the Japan Aerospace Exploration Agency (JAXA). IXO was a merger of NASA's Constellation-X and ESA's XEUS mission concepts.
Astrophysics LISA
The Laser Interferometer Space Antenna (LISA) is a space-based observatory that will allow us to view the Universe in a new spectrum, that of gravitational radiation. This mission is part of the Physics of the Cosmos Program.
Astrophysics Planck
Planck is imaging minor variations relevant in the Cosmic Background Radiation over the whole sky, with unprecedented sensitivity and angular resolution. Planck is providing information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe ...
