About the laboratory

The Laboratory of X-Ray Astronomy of the Sun is a subdivision of the Spectroscopy department in the Lebedev Institute of the Russian Academy of Science. The laboratory was founded during the end of the 1970s, with the aim of studying the Sun and other space objects from rockets and spacecrafts.

Research of the Sun was started in the institute in 1947th onboard rockets R1a and, with the beginning of the space era, were continued using the artificial Earth satellites. In 1957, the scientist of Lebedev Institute for the first time observed short wavelength emission of the Sun from onboard of the second Russian satellite ("Sputnik-2"). In 1963, the first X-ray image of the Sun was obtained. At the end of the 1960s, the first X-ray spectra with the wavelength shorter than 10 angstrom were registered.

Today the laboratory is the leading Russian center to design and construct space telescopes for solar researches. The instruments created in the laboratory operated onboard several "Intercosmos" satellites, onboard interplanetary Fobos stations, and onboard three spacecrafts launched in the frameworks of the CORONAS space program. Now the laboratory is working on developing four scientific instruments intended for the Russian space mission "Interhelioprobe." The laboratory team is also responsible for the "ARKA" project - unique solar telescopes that will provide for the first time the images of solar corona with a spatial resolution of about 100 km. The laboratory also participates in several other projects.

The laboratory has approximately 30 staff members.

Anti-flares on the Sun – the eclipse season has begun on GOES satellites
Not very rare, and not less incomprehensible from it either – the appearance of ‘negative’ spikes of solar flares on the graphs are registered on the incoming data from space. The dips in radiation are not related to real solar activity in any way, but, do originate from the traits of the orbit of the GOES satellite which takes corresponding observations of the Sun.

During the course of summer 2019, there hasn't been a single flare on the Sun
Not a single solar flare of the x-rays class C or higher (a minimum level which is able to have an impact on Earth) has been recorded on the Sun over the past summer of the year 2019. Currently, this is the fourth-longest in duration interval in the modern history of observations when a complete absence of the solar activity has been seeing. The dynamics of the solar minimum is not yet alarming, notwithstanding the duration of the minimum which has already exceeded previous predictions when according to them the growth of solar activity was supposed to begin this summer.

Double Engine Fuels Star's Remarkable Nebula
ESO has just released a stunning new image of a field of stars towards the constellation of Carina (the Keel). This striking view is ablaze with a flurry of stars of all colors and brightnesses, some of which are seen against a backdrop of clouds of dust and gas. One unusual star in the middle, HD 87643, has been extensively studied with several ESO telescopes, including the Very Large Telescope Interferometer (VLTI)
