Scientists found another dwarf planet in Solar System. It's called 2014 UZ224 and located ~ 8.5 billion miles from the Sun.


Proxima Centauri Might Be More Sunlike Than We Thought

New research shows that Proxima Centauri is sunlike in one surprising way: it has a regular cycle of starspots. Its cycle lasts 7 years from peak to peak but is much more dramatic. At least a full 1/5 of the star's surface is covered in spots at once.

******************

On 10 October, ESA's deep-space 35 m-diameter radio dish in Cebreros, Spain, transmitted an 866 sec interstellar message towards the North Star as part of the international 'A Simple Response' project.




******************************

A team of astrophysicists at the University of Portsmouth has created the largest ever map of voids and superclusters in the Universe.

Light from the CMB travels through such voids and superclusters on its way to us. According to Einstein's General Theory of Relativity, the stretching effect of dark energy causes a tiny change in the temperature of CMB light depending on where it came from. Photons of light travelling through voids should appear slightly colder than normal and those arriving from superclusters should appear slightly hotter. This is known as the integrated Sachs-Wolfe (ISW) effect.

It was thought that there was some exotic gravitational effect contradicting Einstein which would simultaneously explain both the Cold Spot and the unusual ISW results.






But scientists found that the new result agreed extremely well with predictions using Einstein's gravity.



The supervoid isn't big enough to explain the Cold Spot. The mystery remains unexplained.

Using statistical analysis and scientific computing, astronomers at Western University have charted a path that most likely pinpoints the very origins of comet 67P/Churyumov-Gerasimenko, which is vital information in discovering what kind of material it is made from and just how long it has been present in our Solar System.


This image from NASA's Dawn spacecraft shows part of Lono Crater (at bottom) within the giant Yalode impact basin on Ceres. Lono is 20 km wide, and Yalode is 260 km in diameter.
