Space astronomy is the branch of astronomy that studies celestial phenomena using instruments located outside Earth's atmosphere. This field enables the observation of astronomical objects and events without atmospheric interference, allowing for more accurate data collection and analysis of the universe's structure, composition, and evolution.

PICsIT (Pixellated Imaging CaeSium Iodide Telescope) is the high energy detector of the IBIS telescope on-board the INTEGRAL satellite. PICsIT operates in the gamma-ray energy range between 175 keV and 10 MeV, with a typical energy... more
Planetary systems are angular momentum reservoirs generated during star formation. This accretion process produces very powerful engines able to drive the optical jets and the molecular outflows. A fraction of the engine energy is... more
The Fresnel interferometric imager is a new kind of high angular resolution space instrument for the UV domain, and the related astrophysical targets. This optical concept is meant to allow larger and lighter apertures in space than solid... more
Recently the numerical simulations of the process of reionization of the universe at z > 6 have made a qualitative leap forward, reaching sufficient sizes and dynamic range to determine the characteristic scales of this process. This... more
The paper gives an exact vectorial solution to the Kepler problem. A vectorial regularization that linearizes the Kepler problem is given using a Sundman transformation. Closed form expressions describing the Keplerian motion are deduced.... more
A review of the HAXTEL project devoted to the development of a Laue lens telescope for hard X-/gamma-ray observation of the continuum spectra of celestial sources is presented. Main design properties, open issues, the status of the... more
We developed a new technique for registration of the far solar corona from ground-based observations at distances comparable to those obtained from space coronagraphs. It makes possible visualization of fine details of studied objects... more

Results from photographic observations of the white light solar corona conducted during the total phase of the total solar eclipse on March 29, 2006 in Manavgat, Turkey are shown in this work. Spectroscopic study of the green 530.3 nm... more
The 10-100 keV region of the electromagnetic spectrum contains the potential for a dramatic improvement in our understanding of a number of key problems in high energy astrophysics. A deep inspection of the universe in this band is on the... more
A breakthrough in the sensitivity level of the hard X-/gamma-ray telescopes, which today are based on detectors that view the sky through (or not) coded masks, is expected when focusing optics will be available also in this energy range.... more
X-ray-like background has the ability to introduce significant systematic and statistical errors to astronomical measurements from space-based X-ray observatories. Statistical errors from radiation-induced X-ray-like background can... more
Early in his Studies in Ethnomethodology, Harold Garfinkel argues that 'doing, recognizing, and using ethnographies' is 'for members a commonplace phenomenon'. He makes an intriguing remark on members' uses of 'anthropological... more
We complete our discussion in the previous papers The Moon Creation And Motion (IV) The Moon Creation And Motion (V) Let's remember the last conclusions and left questions for which we write this paper - Mars had migrated from (84... more
Let's summarize the contradiction point in following: (1) Lorentz Transformations tell us that – Particle 4 values are changing with high- velocity motion – these values are: Particle Mass, Length, Distance And Time In our previous... more
Paper Question Why Mercury Day Period =175.94 Solar Days? Let's try to explain this question in following… I suppose the solar system is one building and each planet is a part of it – for that reason – each planet data is created... more
Why does Earth Moon Orbit regress? Abstract Earth Moon regresses yearly 19 degrees which means 1.44 degrees per month (Lunar nodes are moving west by about 19° per year) Paper Hypotheses 1. Moon Orbit Regression proves that "Energy is... more
Paper Hypothesis There's a light beam its velocity 1.16 mkm/sec travels from Pluto to Earth Axis which creates the connection between Pluto on one side and Earth with her Moon on the other Side Based on this connection Pluto and the Moon... more
Solar Group Creation And Motion (A description which this paper tries to prove) 1- The Solar System Is created of one energy only - this one energy travels through the solar group from point to another point – creating the planet... more
How the Solar Group is Created? Let's summarize it in following (The Next Story is hypothesis which we try to prove in this paper) (Part I) 1- A light beam with velocity 1.16 mkm travels for 1 second Based on this light energy Pluto... more
Planet Motion Trajectory is NOT An Ellipse Main Idea I- Why The Moon Motion Is An Elliptical (or Circular) Trajectory? - Earth moves daily a distance =2.58 mkm - Earth motion direction is straight trajectory approximately declines by... more
During 2013-2019 – I have studied the solar group geometry and discovered the following 5 Equations: 1- Planet Gravity Equation (Point 2-1) 2- Planet Orbital Distance Equation (Point 2-2) 3- Planet Diameter Equation (Point 2-3) 4- The... more
- The Solar Group Main Energy is sent from Jupiter to Pluto – This energy sending is continued for 2 sequence solar days - Neptune used Jupiter Sent Energy consuming 16% of this total energy and the rest of Energy Neptune reflected it... more
Abstract This Paper tries To Prove The Following Hypothesis: Paper Hypothesis - The Solar Group is Created from One Energy. - This One Energy passes through the solar group – to create the planet diameter (matter) and orbital... more
Saturn Effect On The Solar Group Geometry Saturn shows Clearly The Solar Group Geometrical Structure. The Basic Hypothesis: The Solar Group Is One Trajectory Of Energy And Each Planet Is A Point On This Same Trajectory… i.e. The... more
The Main Conclusion The solar group can't be created by any random process. i.e. The Big Bang Concept is Unreal The previous conclusion is produced easily and clearly through the solar planets data analysis.. That means… The Big Bang... more
The Hypothesis "There's No Gravity Found By The Sun" This paper provides 5 proves for this hypothesis which are: 1- Planet Orbital Distance disproves The Sun Gravity Concept 2- The Sun Gravity Value... more
Earth velocity daily (2.58 mkm) = Pluto velocity daily (0.406 mkm) x 2π The previous relationship is found based on 2 reasons –at least- which are: 1- Earth and Pluto are the 2 ends of the solar group main energy trajectory. 2- Earth... more
Abstract - The rate 1.0725 is found frequently between many solar planets orbital and internal distances (a constant rate) - I suggest this rate is found because of Lorentz Contraction Phenomenon i.e. - There's a difference in... more
Abstract How The Matter Is Created? Why the particle has double nature? What's The Gravity Reason And Mechanism? Does the gravity needs time to effect or works instantly? If the Planet moves by gravity, why does the moon revolve... more
Орел и решка Человека. ______________ Имя «зеленые человечки», носимое Пришельцами, оправданно: кожа их впрямь зелена, и цвет этот, писал Циолковский, дань пище их: как солнцем лист, они кормятся чистым Огнем и с тем есть автотрофы. Цвет... more
