SPEKTR-RG X-RAY SPACE OBSERVATORY

A Russian Proton-M rocket launched the Spektr-RG X-ray space observatory for Roscosmos and the German Aerospace Center from Baikonur Cosmodrome, Kazakhstan on July 13, 2019. -- Full Story: https://www.space.com/russia-launches-x-ray-space-observatory-spektr-rg.html Credit: Roscosmos

Пуск ракеты-носителя «Протон-М» с разгонным блоком «ДМ-03» и новой орбитальной обсерваторией «Спектр-РГ» запланирован 13 июля в 15:31 мск. Главная ее миссия — исследование Вселенной в рентгеновском диапазоне электромагнитного излучения, создание «карты» видимой Вселенной, на которой будут отмечены все достаточно крупные скопления галактик.

+Animation + Very little is known about the Universe. The ingredients that make up four percent of its energy density – ‘normal’ material such as protons and neutrons – is only a very small part of the ‘Universe recipe’. What the other 96 percent is composed of remains a mystery. Today it is believed that 26 percent is Dark Matter. However, the largest share, estimated at 70 percent, is comprised of Dark Energy. To track this down, scientists must observe something unimaginably large and extremely hot. Galaxy clusters are composed of up to several thousand galaxies that move at different velocities within a common gravitational field. Inside, these strange structures are permeated by a thin, extremely hot gas that can be observed through its X-ray emissions. This is where eROSITA’s X-ray ‘eyes’ come into play. They allow to observe galaxy clusters and see how they move in the Universe, and above all, how fast they are travelling. We hope that this motion will tell us more about Dark Energy. https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-36232/#/gallery/35604 Deutsche Version: https://youtu.be/JxzksObzjss Cleanfeed: https://vimeo.com/342935821

In this video I talk about the upcoming e-ROSITA mission on board of Spekr-RG due to launch Friday 21st June 2019. How X-ray detectors work, what they are good for looking at and how this mission will tear the skies apart.

I'm so excited to join the eROSITA team! Here's why. ----- eROSITA is an X-ray survey of the entire sky launching on June 21, 2019. Over the next two years, it will produce the highest-resolution, faintest all-sky X-ray maps, revealing over 7,000,000 supermassive black holes and 100,000 galaxy clusters. Each of these high-energy sources can be used to probe the nature of dark matter and dark energy. In this video, I explain how we cosmologists use galaxy clusters.
