Cosmic Origins
Searching for answers about our universe and its origins

About Cosmic Origins

How did we get here?

Answering this question is one of the key goals in NASA's Astrophysics Division, and is the main objective of its Cosmic Origins (COR) Program.

Here are some of the topics our work focuses on:

  • Stellar lifecycles and the evolution of the elements
  • Early formation and evolution of planetary systems
  • Archaeology of the Milky Way and its neighbors
  • History and evolution of galaxies and supermassive black holes
  • First light and reionization

No one mission or observatory can provide all the answers. The Cosmic Origins Program includes telescopes that together operate across much of the electromagnetic spectrum. From the iconic Hubble Space Telescope’s groundbreaking science to the future discoveries awaiting us with the James Webb Space Telescope and more to come, Cosmic Origin's facilities help us in our search for answers to the biggest questions about our universe and its origins.

A New Portrait of the Cosmos is Coming. The Nancy Grace Roman Space Telescope, formerly known as WFIRST, is an upcoming space telescope designed to perform wide-field imaging and spectroscopy of the infrared sky. One of the Roman Space Telescope's objectives will be looking for clues about dark energy — the mysterious force that is accelerating the expansion of the universe. »  Read More
NASA | Swift: A Decade of Game-changing Astrophysics. Nov 20, 2014: Over the past decade, NASA's Swift Gamma-ray Burst Explorer has proven itself to be one of the most versatile astrophysics missions ever flown. It remains the only satellite capable of precisely locating gamma-ray bursts — the universe's most powerful explosions — and monitoring them across a broad range of wavelengths using multiple instruments before they fade from view. »  Read More
TESS Mission's First Earth-size World in Star's Habitable-zone. NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. Scientists confirmed the find, called TOI 700 d, using NASA's Spitzer Space Telescope and have modeled the planet's potential environments to help inform future observations. »  Read More
