    Image: Hubble views two galaxies merging

    Galaxy NGC 6052, located around 230 million light-years away in the constellation of Hercules.

    This image, taken with the Wide Field Planetary Camera 2 on board the NASA/ESA Hubble Space Telescope, shows the galaxy NGC 6052, located around 230 million light-years away in the constellation of Hercules. t would be reasonable to think of this as a single abnormal galaxy, and it was originally classified as such. However, it is in fact a “new” galaxy in the process of forming. Two separate galaxies have been gradually drawn together, attracted by gravity, and have collided. We now see them merging into a single structure.

    As the merging process continues, individual stars are thrown out of their original orbits and placed onto entirely new paths, some very distant from the region of the collis...

    Mysterious radio signals from space discovered to be a much better test of Einstein's general relativity theory

    A new way to test one of the basic principles underlying Einstein’s theory of General Relativity using brief blasts of rare radio signals from space called Fast Radio Bursts (FRB) is 10-100X better than previous testing methods that used gamma-ray bursts. The new method is considered to be a significant tribute to Einstein on the 100th anniversary of his first formulation of the Equivalence Principle, which is a key component of Einstein’s theory of General Relativity...

    “Forbidden” substances may Increase Heat Transfer rates and Strengthen Magnetic fields on Super-Earths

    December 30, 2015, Categories  Astronomy/Space

    Using math models, scientists have ‘looked’ into the interior of super-Earths and discovered hey may have compounds that are forbidden by the classical rules of chemistry – these substances may increase the heat transfer rate and strengthen the magnetic field on these planets. The researchers attempted to see which compounds may be formed by S, O, and Mg at high pressures. These particular elements were not chosen by chance. “Earth-like planets consist of a thin silicate crust, a silicate-oxide mantle – which makes up ~7/8 of the Earth’s volume and consists more than 90% of silicates and magnesium oxide – and an iron core. We can say that magnesium, oxygen, and silicon form the basis of chemistry on Earth and on Earth-like planets,” says Oganov...

    Did you know NASA is with you when you fly? Here’s their 2015 aeronautics innovations incl. making air travel more fuel efficient, less harmful to the environment and much quieter, all the while enabling the skies to safely handle unprecedented growth in global air traffic that will increasingly include unmanned aircraft systems.

    Within NASA, this work – in labs, workshops and wind tunnels throughout the nation, often in partnership with other federal agencies, industry and academia – is managed in D.C. by Aeronautics Research Mission Directorate, ARMD...
