Re: Early Mars Viewing

Musk said that he would like to die on Mars. It's suitably bleak enough.

Re: Mars

Lots of dusky detail there Brian, and irregularities along the edge of the icecap.

Light pollution and breast cancer

Skywatchers are probably not going to get much sympathy from the powers that be to control light pollution solely on the grounds of it causing problems for astronomical observations. We need to highlight as many of the deleterious effects of light pollution on society and nature as we can muster. A ...

Everybody is getting in on the act. It's a satellite gold rush.

Re: What to do with unwanted gear

Some flea-market stallholders will take virtually anything if it's free. It's worked for me.

Probing Mars' subsuface

Relatively deep subsurface sampling on Mars has yet to be achieved, despite the number of landers that have arrived there since the Viking landers in the 1970s. Of the three space probes currently heading for Mars, the NASA and Chinese probes carry landers, while the .United Arab Emirates probe is a...

China launches its Mars lander-probe

Yesterday, China successfully launched its Mars-lander from Wenchang Space Centre on the southern island of Hainan. China's largest lift vehicle the Long March 5 Y-4. In 2020 Mars will be at its closest distance to Earth. It's expected that the probe will arrive at Mars in February. It will attempt ...

Re: We are not alone ...

What offence Cliff? When I pointed out to the neighbours that their security light was causing a problem for other locals, they simply switched it off. There were no demographic considerations involved. Even small communities can and do blight their environment with intrusive lighting. At least, ext...

Re: We are not alone ...

We seem to have shot off on a tangent here Cliff. l'm not an overpopulationist,I've seen the data. One thing we can be certain about is that we are unlikely to see evidence of extraterrestrial life in our lifetime, unless, of course, they visit us. Better put the kettle on just in case. :wink:

Re: Comet Neowise

I sympathise with you Cliff. I was lucky. Some years ago the next door neighbours installed a trigger-type security light in their back garden. It was powerful, even lighting up the tops of tall trees on the back field, and I'm sure that a passing ground beetle would have triggered the light, it was...

Re: Comet Neowise

Your last shot of the comet is quite nice Cliff. That security light in your first pic is really awful. Have you considered having a stroll over there to ask the boss if he will have it shaded, so as to direct the light downwards?
Also, are you aware that there's a bylaw against light nuisance?

Re: We are not alone ...

Word meanings can change over time. Civilisation used to mean "town-dwelling" ( civil society )' but now it seems to mean any number of things, such has having impeccable manners and being intelligent, etc. Galactic civilisations are also referred to as synonymously meaning intelligent life. Life do...

Re: Comet C/2020 F3 NEOWISE - 18 July 2020

A neat little sketch Ian. I've just observed the comet for the first time, 11 pm BST, from the gravel path near the sports field and past barricading trees. Opticron 8X40s were used. The comet was not too easy to see with the unaided eye, due to natural summertime air glow and light pollution over t...

The Kinman Dwarf galaxy's missing star

Astrophysicists, using the Very Large Telescope ( VLT ) in Chile are searching for a " monster" star that has mysteriously disappeared in the Kinman Dwarf Galaxy 70 million light years away in Aquarius. At its great distance the star cannot be seen, but the research team confirmed its presence in sp...
