As NASA will be looking for dark energy?
Source:The First years of the existence of the Universe are hidden from human eyes behind the clouds of hot gas and subatomic particles. But a new space telescope (WFIRST) may finally uncover some of the greatest mysteries of the early Universe. Moreover, researchers do not exclude that the launch of WFIRST will help to answer the famous question, formulated by the Italian physicist Enrico Fermi, “where is everybody?” As the official website of NASA, the specialists of the space Agency recently approved the development and testing of the equipment. One of the main tasks of the new space telescope will study the Universe in the infrared range, which should help in the search for elusive dark energy.
WFIRST — a worthy successor to Hubble?
Yes. The potential of the new space telescope is enormous — with its help scientists hope to get data on exoplanets, to explore the distant Universe. and to solve , at last, the mysteries of dark matter and dark energy. With the latest technology, capable of detecting weak infrared signals over large distances, and create panoramas of deep space. In the past, no telescope could see so deeply into the abyss of the cosmic ocean. Ultimately, the telescope is intended to replace the mainstay of the science of space — Hubble. Precisely because of this legendary telescope was made possible by some of the most incredible discoveries about our Universe, including the discovery of the most distant star known to science, and the fact that the universe is expanding much faster than we thought.
The New telescope will feature a mirror of the same size as the Hubble telescope, but with a broader overview of the space. Recall that was launched in April 1990, but thanks to five servicing missions, the telescope still works. In turn WFIRST able to visualize the region in the sky, 100 times greater than those, which explores the Hubble. And this even though both telescope has a 2.4-metre mirror to look at the universe through him. NASA called the new telescope, Hubble's cousin.
Space telescope-the Hubble legend himself
In search of dark energy
Observing the Universe with high-tech tools like the Hubble and WFIRST, astronomers hope to find out why the universe starts to expand with acceleration. At the heart of this mystery, as probably you know our regular readers, lies — a mysterious form of energy that is believed to be about 70% of the Universe. Nevertheless, she remains completely elusive and invisible that we wouldn't do. But today everything can change. WFIRST is designed to make the most precise measurements of how dark energy and dark matter affect the Universe by observing cosmic phenomena in action, including supernovae and the formation of clusters of galaxies.
These observations will then be used to measure the rate of expansion of the Universe. “To understand how evolved from a homogeneous hot gas in stars, planets and people, need to learn the beginning of this process, looking at the early days of the Universe», — believes Jeffrey Kruk, the first researcher in the Center NASA Goddard in Maryland.
In search of exoplanets
Since in 1992 opened the first scientists were looking for an outlandish alien worlds and signs of life. To date we have discovered about 4,000 exoplanets orbiting various stars. Most of them we found out thanks to the NASA Kepler mission and the transit of the satellite Exoplanet Survey Satellite (TESS). With the help of a cousin of Hubble, scientists hope to find potentially habitable exoplanets.
the Telescope will monitor 100 million stars for hundreds of days and is expected to detect new exoplanets around 2,500
As writes the edition , the launch of the space telescope WFIRST will be held in the middle of the 2020-ies, and the maximum projected cost of the telescope is about $ 4 billion. Work on WFIRST will run until September 2020 in the budget for the current fiscal year. However, the NASA budget for 2021 implies the cessation of funding of WFIRST in order to focus the telescope James Webb, the launch of which is scheduled for March 2021. Well, we're going to hope that the future space telescope WFIRST will not be called into question.
