"Dr Collins is cautious to conclude that the galaxy has no dark matter halo, based on the current evidence" now that is a very polite way of saying that it is nonsense. An unusually transparent galaxy about the size of the Milky Way is prompting new questions for astrophysicists. The object, with the great name of NGC1052-DF2, appears to contain no dark matter.If this turns out to be true, it may be the first galaxy of its kind - made up only of ordinary matter. Currently, dark matter is thought to be essential to the fabric of the Universe as we understand it.

Over a decade ago, I was always very proud when shopkeepers et al would compliment me on the politeness and manners of my daughters. But I have to ask are good manners a redundant concept these days, any disagreement, it seems is the instant trigger for obscenities and vile online comments using offensive language. The expression ‘agree to disagree’ seems redolent of a distant kinder era. Universal access to social media provides an all to easy means for a great many people to launch into a tirade of vile filth and downright nastiness on Facebook and Twitter. In a very short space of time, many people have become unable to contemplate that someone might hold different views to their own and have the right to do so.

Peter Williams swept to victory in the Teignmouth Central Ward by-election held on Monday 5th February, with 438 votes, increasing the majority from 44 votes to 73 votes over the second place Conservative with 365. The by-election was caused by the sad passing of veteran Liberal Democrat councillor Roy Phillips. Roy won the Central Ward by-election held in September 2016 with daughter Julie. At the age of 91, Roy became the oldest by-election victor in the UK. Peter has pledged to work for Teignmouth and "the prosperity and happiness of our town" will be his first priority. Clearly the voters of Central Ward have rejected the proposal to build 255 houses at Higher Exeter Road. The balance between the parties on Teignmouth Town Council remains unchanged with 6 Conservatives, 5 Liberal Democrats and 1 Independent.

Have scientists found billions of exoplanets outside our Galaxy? A group of researchers at the University of Oklahoma has just announced the discovery of a large population of free-floating planets in a galaxy 3.8 billion light-years away. Their results were published February 2 in the Astrophysical Journal Letters. http://iopscience.iop.org/article/10.3847/2041-8213/aaa5fb/meta Detecting planets in our part of the galaxy using the transit method or spectrometry, however quasar microlensing is great for sampling more distant stellar populations. Quasar microlensing provides a means to probe extragalactic planets in the lens galaxy, by studying the microlensing properties of emission close to the event horizon of the supermassive black hole of the background quasar, using the current generation telescopes.
