The science goals of the SMD Astrophysics Division are breathtaking: we seek to understand the universe and our place in it. We are starting to investigate the very moment of creation of the universe and are close to learning the full history of stars and galaxies.

We are discovering how planetary systems form and how environments hospitable for life develop. And we will search for the signature of life on other worlds, perhaps to learn that we are not alone. NASA's goal in Astrophysics is to "Discover how the universe works, explore how it began and evolved, and search for life on planets around other stars. Please visit the " Decadal Planning " page for additional information about survey.

Astrophysics comprises of three focused and two cross-cutting programs. These focused programs provide an intellectual framework for advancing science and conducting strategic planning. They include:. The Astrophysics current missions include three of the Great Observatories originally planned in the s and launched over the past 28 years.

Additionally, the Fermi Gamma-ray Space Telescope explores the high-energy end of the spectrum. SOFIA, an airborne observatory for infrared astronomy, is in its extended mission phase.

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.

The near future will be dominated by several missions. Currently in development, with especially broad scientific utility, is the James Webb Space Telescope. Completing the missions in development, supporting the operational missions, and funding the research and analysis programs will consume most of the Astrophysics Division resources.

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. Since the decadal survey, the way the universe is viewed has changed dramatically.

More than 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 Decadal survey New Worlds, New Horizons in Astronomy and Astrophysics.

The priority science objectives chosen by the survey committee include: searching for the first stars, galaxies, and black holes; seeking nearby habitable planets; and advancing understanding of the fundamental physics of the universe.

In the Astrophysics Implementation Plan was released which describes the activities currently being undertaken in response to the decadal survey recommendations within the current budgetary constraints. The plan was updated in , , and most recently in The Roadmap presents a year vision for astrophysics using the most recent decadal survey as the starting point. Universe Learn About This Image.

ANNOUNCEMENT

 Хочешь от меня избавиться? - надулся Хейл. - Если честно - да, - Не надо так, Сью, Ты меня оскорбляешь. Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью. Вообще-то она ничего не имела против этого имени, но Хейл был единственным, кто его использовал, и это было ей неприятно.

Он застонал. Проклятые испанцы начинают службу с причастия. ГЛАВА 92 Сьюзан начала спускаться по лестнице в подсобное помещение. Густые клубы пара окутывали корпус ТРАНСТЕКСТА, ступеньки лестницы были влажными от конденсации, она едва не упала, поскользнувшись.

Но Стратмор понимал, что Хейл не станет долго держать язык за зубами. И все же… секрет Цифровой крепости будет служить Хейлу единственной гарантией, и он, быть может, будет вести себя благоразумно. Как бы там ни было, Стратмор знал, что Хейла можно будет всегда ликвидировать в случае необходимости.

Росио задумалась. - Нет, больше. В этот момент кровать громко заскрипела: клиент Росио попытался переменить позу.
