This brief article explains how a 5000 degree surface of the sun is able to heat the sun’s corona to a temperature higher then 1 million degrees. The explanation is made for everyone to understand and an experiment is described on how to heat something in a similar way to a temperature higher then the source temperature here on earth.

It is proposed that the explosion, or actually, the fast expansion of the envelope of a core-collapse supernova is caused by the action of a powerful electric field that is formed as a consequence of the action of the shock wave on the interface between the proto-neutron star and the plasma of the envelope during the first minutes of the collapse. The proposal explains also the shell-like shape of core-collapse supernovae remnants, the reason why there are different ejecta velocities and the origin of the radial
magnetic field which has been observed in young supernovae and shows that a supernova is a very
powerful particle accelerator. It is shown for the first time how the dynamics of the explosion is clearly connected to the light curve of the supernova. It is calculated that the radius of supernova KSN 2011d is about 411.4 solar radii.

It is shown that using changes in the planet's rotation speed, one can easily control gravity on the surface of any planet, including the Earth. The acceleration of rotation will lead to a decrease in gravity on the surface of the planet, up to a state of weightlessness; and slowing down the rotation leads to an increase in gravity. Moreover, the energy for such transformations will be available to humanity in the near future, which will make it possible to control gravity on Earth and make most of the planets suitable for human life.

The use of parallax angles is one of the standard methods for determining stellar distance. The problem that arises in using this method is how to measure that angle. In order for the measurement to be correct, it is necessary for the object we are observing to be stationary in relation to the sun. This is generally not true. One way to overcome this problem is to observe the object from two different places at the same time. This would be technically possible but will probably never be realized. Another way to determine the distance is given in [1]. With certain assumptions, this is a mathematically completely correct method. After the publication of the third Gaia's catalog [2], we are now able to test the proposed method using real data. Unfortunately, for the majority of stars it is not possible to obtain the distance directly, but with the help of some additional measurements we would be able to indirectly determine the distance of such stars.

Starlight and radio waves from QSOs share the ability to be polarized. For many regions of the Milky Way the alignment of the polarization directions of starlight is evident. However, it is useful to have a numerical alignment function that can be used to judge the significance of the correlations. The Hub Test provides such a function. Surveying the Galaxy with data from two catalogs of polarized starlight, Heiles 2000 and Berdyugin 2014, reveals an unusually well-aligned region which is then studied in more detail. Applied to a catalog of polarized radio QSOs, Pelgrims 2014 which is in part derived from Jackson 2007, a survey reveals the most significantly aligned region, which is studied further. Stars and QSOs have contrasting characteristics in terms of distance, degree of polarization, and strength of the alignment. The two most significantly aligned samples of starlight and radio QSOs are analyzed here. The alignment of the starlight sample outperforms all other portions of the Galaxy at the scale of the survey, about ten degrees, while the QSO sample has its polarization directions focusing down on a point extremely close to the QSOs themselves on the sky.
