Sky Surveyors

by Enigma

As the day dies, on the promontory of a mountain at the forefront of the universe, a dome opens. In the reddish opening is a telescope with unusual dimensions. Moments later, the giant’s bright eye comes to life, looking towards infinity. Mechanically we follow his movements and a question comes naturally to our mind: What hides the firmament?

There was a time when this question was debated from a strict philosophical point of view, even metaphysical. But since the man “perched on the shoulders of giants” as Newton says his investigations allowed him to access the back of the cosmic scenery. These discoveries allowed the scientists to deduce a series of theories that explain somehow – rather well – the behavior of Nature and the cosmos.

Despite our sometimes very austere laws, we can only marvel at our understanding of the spectacle of the Universe. We delight in its beauty and somewhere in us, we preserve this look of the poet.

Astronomy remains a science of adventure. We travel almost half of the Earth to observe an asteroid occultation in an atoll of Polynesia; it is sinking in the Antarctic continent to collect meteorites untouched by chemical waste; stratospheric ballooning to witness an exceptional solar chromospheric eruption in ultraviolet radiation; we emigrate to the desert of New Mexico to listen to the music of the stars and to discover another form of life in the universe; we settle on snowy summits at more than 4000 m of altitude to carry out a good program of astronomy. Finally, we do not hesitate to put our men on the Moon, cameras fists!

This adventure of heaven and space is current. Thanks to telescopes, radio telescopes and especially satellites in orbit around the Earth pointed to regions of the sky inaccessible from the ground, the astronomer allowed himself to imagine that everything was now accessible to him and his thirst for knowledge in was increased tenfold.

Sometimes after more than a century of questioning, investigation and analysis, comparing his results with those of researchers in other disciplines, the astronomer finally discovered what formed the Meteor Crater and the Crab Nebula, he has understood the true nature of comets, he knows the past of the solar system and knows that the Sun will eventually go out, he knows how to interpret the rhythm of pulsations of the heart of pulsars, he understands the music of the aurora and the whistles of the geomagnetosphere of Jupiter, he knows that star Eta Carina is suffering and will eventually explode, he observed brightly colored nebulae and hotter than the surface of the Sun, he saw a primitive galaxy older than 13 billions of years, stars shining like a hundred thousand suns (Pistol), he saw storm winds on Mars that raised sand at over 500 km / h, cyclones on Jupiter as vast as the Earth he discovered exop lanets on which perhaps flows liquid water and even discovered a diamond star (V886 Centaurus)!

I’ve been betting with Tenobet for roughly six months on and off, mostly slots plus a bit of Premier League action come Saturday. Honestly, I first joined after a mate sent me a link, and I half expected it to be rubbish.\n\nThe lobby’s decent — somewhere around 2,500 slots last time I scrolled. All the big studios are in: Pragmatic Play, NetEnt, Play’n GO, Betsoft. I mostly stick to Gates of Olympus and Sweet Bonanza, though Bonanza Megaways gets a look in. Live side is Evolution, so no complaints there — real croupiers, roulette round the clock, and Crazy Time if you fancy something daft.\n\nThe sign-up offer on Tenobet is up to ?125 and some bonus spins, wagering sits at 30x , so fair enough. No no deposit freebie that I found, you need ?10 to trigger it. For the up-to-date codes see tenobet since these change. My gripe: the spins expire in 7 days and I wasted a load.\n\nCashouts have been fine. Skrill came back in under 24 hours the two times I tried, Visa took 2-3 days, which is normal for UK banking. Tenobet also takes Bitcoin and the usual e-wallets, but I’ve never used crypto on a bookie. The ID check was painless enough — driving licence and a bank statement, sorted same evening.\n\nNo app on the Play Store, but the mobile site and it’s fine — I’ve placed bets on it on the train plenty. Live chat on Tenobet answered in under ten minutes both times, actual person, decent English. Licensed and regulated for UK players, which is the first thing I check these days.

Been playing at Tenobet since roughly four months on and off, mostly the slots during the week and a bit of Premier League betting at the weekend. Honestly, I only signed up because someone on another thread mentioned it, and I half expected it to be rubbish.\n\nThe lobby’s decent — I reckon about 2,000 slots last time I scrolled. All the big studios are in: Pragmatic Play, Play’n GO, Play’n GO, Yggdrasil. I live on Gates of Olympus and Sweet Bonanza, although the Megaways stuff is where I lose the most. Live side is Evolution, so no complaints there — actual dealers, blackjack tables at all hours, plus Crazy Time and Lightning Roulette.\n\nThe sign-up offer on Tenobet is up to ?125 with some bonus spins, wagering sits at 30x , so about standard. There’s no free-money thing unless I missed it, you need a tenner to trigger it. To check what’s live right now have a look at casino tenobet before you deposit. My gripe: bonus expiry is tight and I wasted a load.\n\nCashouts are the bit I actually care about. E-wallet took about a day the two times I tried, card took closer to three days, which is normal for UK banking. Tenobet also takes Bitcoin and the usual e-wallets, though I haven’t bothered with Bitcoin. Verification was a bit of a faff — passport and a utility bill, done in a day.\n\nNo app on the Play Store, but a browser version which honestly works — I use it more than desktop now. Live chat at Tenobet answered in under ten minutes when I asked about a stuck bonus, human, not a bot loop. It’s UKGC licensed, which is why I stuck around.

You also get Neteller, Visa and some crypto options, though I haven’t bothered with Bitcoin. Verification was painless enough — driving licence and a bank statement, cleared overnight.\n\nThere’s no standalone app that I found, but the mobile site and it’s fine — I’ve placed bets on it on the train plenty.
