Exploring the Universe, Advancing Humanity 

The universe is everything: space, matter, energy, and time.  NASA’s Astrophysics Division is dedicated to pushing the boundaries of discovery and ensuring that America remains at the forefront of space science.  We study how the universe began and evolved, how it works, and where life might exist beyond Earth.  

Through world-class space observatories, state-of-the-art technologies, and a spirit of exploration that defines the American character, NASA is unlocking answers to humanity’s greatest questions—while delivering innovations that strengthen the nation’s economy, technology base, and global competitiveness.  

Working closely with U.S. industry, academic institutions, and international partners, NASA promotes collaboration that advances global understanding and serves mutual interests.  By leading with excellence, the United States ensures that astrophysics research continues to benefit people everywhere while upholding our nation’s legacy of discovery. 

Every discovery from NASA’s Astrophysics Division extends far beyond deep space.  The technologies and data developed for our missions fuel innovation across American industry—advancing breakthroughs in imaging, communications, data science, and next-generation materials.  These innovations not only reveal the nature of the cosmos but also strengthen our economy and improve life here on Earth.  

Current Programs

A Coordinated Effort to Explore the Universe 

NASA’s Astrophysics Division carries out its mission through a balanced portfolio of programs, some of which focus on specific science questions or modes of observing, while other cut across multiple domains of science.

Together, they ensure that the United States continues to lead in scientific discovery, technology development, and exploration. Each program complements the others across wavelength, observing techniques, and celestial phenomena studied—creating a unified approach to understanding the universe from multiple perspectives.

Each program plays a vital role—probing the origins of the universe, studying distant worlds, and supporting a vibrant research community that drives innovation across the nNation.

Current Missions

A Legacy of Discovery, A Future of Innovation

The Astrophysics current missions include two of the Great Observatories originally planned in the 1980s and launched over the past 30 years. The current suite of operational missions includes the Hubble Space Telescope, the Chandra X-ray Observatory, and the James Webb Space Telescope. Additionally, the Fermi Gamma-ray Space Telescope explores the high-energy end of the spectrum. Innovative Explorer missions, such as the Neil Gehrels Swift Observatory, NuSTAR, TESS, and IXPE, as well as NICER, complement the Astrophysics strategic missions. SOFIA, an airborne observatory for infrared astronomy, is in its extended mission phase is GUSTO (Galactic/ Extragalactic ULDB Spectroscopic Terahertz Observatory) with its mission to measure emissions from the interstellar medium to help scientists determine the life cycle of interstellar gas in our Milky Way, witness the formation and destruction of star-forming clouds, and understand the dynamics and gas flow in the vicinity of the center of our galaxy. All of the missions together account for much of humanity's accumulated knowledge of the heavens. Many of these missions have achieved their prime science goals but continue to produce spectacular results in their extended operations. 

NASA-funded investigators also participate in observations, data analysis and developed instruments for the astrophysics missions of our international partners, including ESA's XMM-Newton. Along with these international missions, ESA's Euclid mission which will fly NASA furnished detectors and JAXA's XRISM (X-Ray Imaging and Spectroscopy) mission which uses NASA furnished technologies that will help provide breakthroughs in the study of structure formation of the universe, outflows from galaxy nuclei, and dark matter. 

Near Future

The near future will be dominated by several missions.

The SPHEREx mission will launch in 2025. The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide the first all-sky spectral survey. Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way to explore the origins of the universe.

In 2027 NASA will launch the Nancy Grace Roman Space Telescope. Roman will aid researchers in their efforts to unravel the secrets of dark energy and dark matter, and explore the evolution of the cosmos. It will also discover new worlds outside our solar system and advance the search for worlds that could be suitable for life.

In October 2021, NASA selected a new Explorer Mission, the gamma-ray telescope COSI (Compton Spectrometer and Imager). COSI will study the recent history of star birth, star death, and the formation of chemical elements in the Milky Way.  COSI is also planned to launch in 2027.

The Future

Since the 2001 decadal survey, the way the universe is viewed has changed dramatically. More than 3800 planets have been discovered orbiting distant stars. Black holes are now known to be present at the center of most galaxies, including the Milky Way galaxy. The age, size and shape of the universe have been mapped based on the primordial radiation left by the big bang. And it has been learned that most of the matter in the universe is dark and invisible, and the universe is not only expanding, but accelerating in an unexpected way.

For the long-term future, the Astrophysics goals will be guided based on the results of the 2020 Decadal survey Pathways to Discovery in Astronomy and Astrophysics for the 2020s. It identifies the most compelling science goals and presents an ambitious program of ground- and space-based activities for future investment. The report recommends critical near-term actions to support the foundations of the profession as well as the technologies and tools needed to carry out the science.
