Talkshop analysis of some of the data follows this brief report from Astrobiology at NASA. A team of researchers has provided new information about putative planets in the outer regions of the TRAPPIST-1 system. Currently, seven transiting planets have been identified in orbit around the ultra cool red dwarf star. The scientists determined the lower […]

Much media attention on this new paper this week. Is there a surprise lurking in the details now that the orbit period of the seventh planet has been confirmed?. What the numbers in the diagram show is the orbits per planet in a fixed period (top row), the conjunctions per planet pair in the same […]

Excellent – we outlined this ‘resonance chain’ (as they have now dubbed it) in an earlier post here at the Talkshop [see ‘Talkshop note’ in the linked post for details]. When NASA announced its discovery of the TRAPPIST-1 system back in February it caused quite a stir, and with good reason says Three of […]

The five major moons of Uranus in ascending distance from the planet are: Miranda, Ariel, Umbriel, Titania and Oberon Of these, the first three exhibit a synodic resonance similar to that of Jupiter’s Galilean moons, as we showed here: Why Phi? – the resonance of Jupiter’s Galilean moons Quoting from that post: The only exact […]

Although the author appears sold on the idea of trace gases controlling the temperature of planetary atmospheres, the discussion about planets and water is worth a look. The answer to the question may depend on more powerful space telescopes like the James Webb. Wherever we find water on Earth, we find life writes Elizabeth Tasker […]

The planetary theory aspect appears a bit later, but first a brief review of some relevant details. In this Talkshop post: Why Phi? – a triple conjunction comparison we said: (1) What is the period of a Jupiter(J)-Saturn(S)-Earth(E) (JSE) triple conjunction? JSE = 21 J-S or 382 J-E or 403 S-E conjunctions (21+382 = 403) […]

We did know something about this system already, but more work has led to today’s announcement. Astronomers have never seen anything like this before, says Seven Earth-size alien worlds orbit the same tiny, dim star, and all of them may be capable of supporting life as we know it, a new study reports.  “Looking […]

From Is there life beyond our solar system? If there is, our best bet for finding it may lie in three nearby, Earth-like exoplanets. For the first time, an international team of astronomers from MIT, the University of Liège in Belgium, and elsewhere have detected three planets orbiting an ultracool dwarf star, just 40 […]
