Diamond from the sky

Another otherworldly theory - at https://phys.org/print443181994.html ... the diamond from the sky may have come from the 'lost planet' (but they are not talking about Planet X or 9). In this instance the theory is that the solar system was full of planets, proto planets, or wannabe planets very early on (4.5 billion years ago). The diamond was in a meteorite found in the Nubian Desert of the Sudan and was created under extreme pressure.

Gamma Ray Bursts

Various theories exist on why space telescopes capture images of gamma ray bursts, many of them literally flashes of light. In EU theory it is down to electricity in the universe but in mainstream it is not as clear cut (as far as an explanation is concerned). At https://phys.org/print443091109.html ... which concerns a paper in the Monthly Notices of the Royal Astronomical Society (2018) DOI:10.1093/mnas/sty013 ...

Ismenia Patera

Ismenia Patera means, in Latin, a 'flat bowl' - but the term was also used to describe a flat crater on Mars. Its origin has caused a bit of head scratching - as it looks nothing like an impact site. Go to https://phys.org/print442754485.html ... we learn that Mars topography is open to differences of opinion, and no wonder. It is split into two parts. In the north we have what are called the lowlands while in the south we have the highlands. In general, the south is much higher in contour than the north. Why is this?

Sun's rotating core

Jovan sent in a raft of links - most of them dated. In case you missed them here is another opportunity. Ice on Mars is the subject at http://blogs.discovermagazine.com/d-brief/2017/11/15/life-on-mars-ice/ ... which is basically saying that if micro-organisms existed on Mars in the past where might they have survived. In icy regoliths is one idea.

Black Hole Swarm

At www.space.com/40196-black-hole-swarm-milky-way-heart.html ... a swarm of thousands of black holes MAY surround the giant black hole believed to be at the heart of our galaxy, according to a new study. At the centre of the Milky Way lies Sagitarrius A (thought to be a 'massive' black hole). Cosmologists think black holes grow by engulfing smaller black holes - and the search has been on for them.

Transient Star phenomena

This one is at https://phys.org/print441899749.html ... astronomers found 72 bright and fast bursts of light - gone within a week (sometimes lasting a month). They were discovered during the Dark Energy Survey Supernova Programme, a global effort to understand dark energy (assuming there is actually something to understand). They have a similar maximum brightness to supernova but they last a fraction of the time. Supernovas can last for many months and are thought to be stars exploding, a paradigm that is under pressure it would seem from these discoveries.

Life on Venus

Gary sent in this link - http://time.com/5224561/venus-life-atmosphere-bacteria/ ... the temperatures on Venus surface is reputed to be as high as 465 degrees C - which is hot enough to melt lead. In the atmosphere the heat gets less the higher one goes (according to the theory). Most organisms could not survive on the surface of Venus (so it would seem). However, a study published in the journal Astrobiology suggests Venus may  harbour vast colonies of bacteria (in its atmosphere). Shades of Velikovsky and vermin out of the sky.

Transparent Galaxy

At www.bbc.co.uk/news/science-environment-43543195 ... (see also https://tallbloke.wordpress.com/2018/03/28/ghost-galaxy-prompts-cosmic-m... ) ... 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 www.skyandtelescope.com/astronomy-news/astronomers-witness-x-ray-burst-f... ... 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 www.scientificamerican.com/article/looking-for-planet-nine-astronomers-g... ... 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.
