Transparent Galaxy

At ... (see also ) ... a transparent galaxy about the size of our Milky Way is causing problems for cosmologists. The study is published by Nature journal and the researchers seem to have discovered a galaxy that is dark matter free. Oh dear. The galaxy is not abundant with stars which makes it even more mysterious - but those that can be seen are banded in bright clusters.

Neutron Star

In a link that provides an insight into mainstream thinking - go to ... sent in by Jovan. Astronomers have discovered a neutron star with an old red star as its companion - or that is what is being claimed. Red stars are thought to be near the end of their food supply, it's core almost burnt out, in a series of stages. These layers are ejected by the star's own solar wind, and in turn this material may possibly collide with its companion, the neutron star.

Planet 9 and the Scholz star

Jovan sent in a number of links. This one is on the search for Planet Nine - go to ... Looking for Planet Nine astronomers gaze into the abyss (or that spot in the solar system that is hidden from our view). To begin with you need to go back to claims made a year or two ago that apparent motions of object beyon Neptune are being influenced by 'a very big something much further out', hidden from view save for its subtle gravitational tugs.

Exomoons and Planet Scatter

Jovan sent in the link ... and once again we are back into mainstream worlds in collision. The title is 'The Fate of Exomoons when Planets Scatter' - planets interacting with each other on rogue orbits are thought to be a common phenomenon of our early solar system and therefore by extrapolation, other star systems as well. After all there are a lot of exoplanets out there. What happens to the moons when planets interact with each other?

Comet X-rays

At ... scientists say they have solved the mysteroy as to why comets emit x-rays. Comets are regarded as cold objects whilst x-rays are normally associated with hot objects such as the sun or stars in general. However, in the solar system comets interact with the solar wind - and plasma. This creates a bow shock behind the comet. The key is therefore the Sun. The solar wind creates plasma turbulence and in turn this causes the electrons to become highly active and in this the bow shock plays a role, causing particles to speed up.

Galaxies Spin like Clockwork

At ... Astronomers discover that galaxies spin like clockwork, and are in tune with each other. Regardless of whether a galaxy is big or small if you sit on the extreme edge of its disc it would take around a billion years to go all the way round, we are told. By using simple maths you can demonstrate all galaxies of the same size have the same average interior density. You won't find a dense galaxy rotating slowly and a lesser densiity one slower.

Water and Moon

At ... how does water change the Moon's origin story? What a beautiful question. Mainstream claims the Moon was formed 4.5 billion years ago when an object collided with proto-Earth and ripped out a hot and partly vapourised blob that became a disc of material. It proceeded to orbit around the Earth - and eventually accreted into what is now our Moon. Hydrogen, it is thought, seeped from the disc, along with other volatile elements, and were lost in space.

Black Hole Gas Outflow

Black Holes continue to make waves it would seem. At ... a Taiwanese astronomer, Yashiki Toba, and his team, have established that ionised gas outflow driven by a super massive black hole does not necessarily affect its host galaxy - impacting on the molecular gases in the galactic disc.

Growing Black Holes

Like the five magic beans of Jack the Giant Killer, black holes just keep on growing, threatening to outgrow their galaxies (out performing the production of new stars). For this see

Sun Spot Erupts

Sun spots have been in short supply of late and even when they have provided a CME it has been weak. Same may  be true of this one - go to for info. The sun spot exploded a couple of days ago and will arrive today, 15th February 2018. See the short video below ...
