Really? Is this what we were all waiting for?

to be honest, while the alien megastructure is a cookie idea, I highly doubt that those aliens woke up one day and thought: "hm, let's send laser pulses at this particular random spot in space sometime in the next 6 days".

here's something we didn't consider yesterday in the meeting on extra-solar planets!

this is because you did not read the nature paper I have posted (see post a few lines below ...)

Also our British friends are doing good .... Apparently an ESA employee leaked this news to them -- wait for it .... Rosetta, Aliens .... just read it I do not want to spoil it for you

I'm sorry, I had to do it! We can't keep the secret much longer!

Its doing it again. Anyone wants to play the "explain this" game?

New debates on 'old' topic: https://phys.org/news/2018-01-alien-megastructure-dimming-mysterious-star.html? see blog posts in link for more info

An alien star passed through our Solar System just 70,000 years ago, astronomers have discovered. No other star is known to have approached this close to us. An international team of researchers says it came five times closer than our current nearest neighbour - Proxima Centauri. Passing straight through the Oort Cloud region. This must have left some sort of mark maybe? A binary system of a red and brown dwarf (8% and 6% solar masses) so maybe not a too significant impact on trajectories in the Oort cloud?

I read this earlier and thought it might be another one of those alien conspiracy stuff. Freaky stuff.

what about taking a ride on one of these? - especially if they come with some companion planets? when is the next shuttle coming?

Earth is a pale blue dot when viewed from space. Now astrobiologists have worked out the likely colours of Earth-like planets orbiting other stars

I Knew!!! I Knew!!! They are all around. I always though Marek was one :) "I believe in Father Frost. But not too deeply. But anyway, you know, I'm not one of those people who are able to tell the kids that Father Frost does not exist"

His rival putin on the other hand... He got into an ultra-light aircraft to guide birds during their migration - from the video it seems that only very few birds think he is credible (as a guide). --> http://www.telegraph.co.uk/news/worldnews/vladimir-putin/9524900/Flying-Vladimir-Putin-leads-birds-on-first-ever-migration-in-latest-publicity-stunt.html

Yup. My structural perfection is matched only by my hostility.

should we all go home then? apparently you just need a balloon

paper here: http://journalofcosmology.com/JOC22/MILTON%20ISOLATION_final.pdf Not the best journal out there, it seems: https://en.wikipedia.org/wiki/Journal_of_Cosmology They currently have an open call for papers on Astro-Theology ! :)

wow. the wiki page is hilarious. maybe i'll submit something

Let's start betting which party Aliens vote: GREEN, BLUE, RED, BLACK?

http://astrobiology.nasa.gov/ for the moment is down. My bet, the microbe they found notified its cousins and they are currently invading the US

you can still see the rest of it here: http://www.nasa.gov/multimedia/nasatv/index.html a good link with a summary and discussion on the announcement is here: http://www.guardian.co.uk/science/2010/dec/02/nasa-life-form-bacteria-arsenic

Sounds like one of Calvin's alibis: Aliens! Dad, aliens! A sarcastic Venusian entered the kitchen...

i think they could also be a cause for Greece's economic crisis

Well, then I suggest to elect Spaceman Spiff instead of Papandreou as Prime Minister! :-)

I think it's time to quote "Calvin & Hobbes" (yes, I'm still the guy who knows a C&H for any situation in life) "Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us." One should sue this idiot for racism against extraterrestrials!!

not scientific but nice, Alien trailer voted best of all

Seems we have 1.7 billion years before we need to find a new place to live, when Earth's 'property value' is reduced to zero.

so it took us 70% of the time Earth is in the habitable zone to develop, would this be normal or could it be much faster? In other words, would all forms of life that started on a planet that originated at a 'similar' point in time like us, be equally far developed?

That is actually quite tricky to estimate rly. If for no other reason than the fact that all of the mass extinctions we had over the Earth's history basically reset the evolutionary clock. Assuming 2 Earths identical in every way but one did not have the dinosaur wipe-out impact, that would've given non-impact Earth 60million years to evolve a potential dinosaur intelligent super race.

The opposite might be true - or might not be ;-). Since usually the rate of evolution increases after major extinction events the chance is higher to produce 'intelligent' organisms if these events happen quite frequently. Usually the time of rapid evolution is only a few million years - so Earth is going quite slow. Certainly extinction events don't reset the evolutionary clock - if they would never have happened Earth gene pool would probably be quite primitive. By the way: dinosaurs were a quite diverse group and large dinosaurs might well have had cognitive abilities that come close to whales or primates - the difference to us might be that we have hands to manipulate our environment and vocal cords to communicate in very diverse ways. Modern dinosaur (descendents), i.e. birds, contain some very intelligent species - especially with respect to their body size and weight.
