Helio replied to the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone.We still lack a lot of useful data for much of a distribution. I can estimate radii and mass if one of these is known, but I'll need to...

Helio replied to the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone.Here is a current listing of all exoplanets by stellar type that are in the extended HZ (luminosity bump -- "lumidge"). This matches...

Helio replied to the thread There's an infinite amount of energy locked in the vacuum of space-time. Could we ever use it?.The Casimir Experiment demonstrated their existence. Agreed. Infinite also seems used as hyperbole to express something beyond...

Helio replied to the thread There's an infinite amount of energy locked in the vacuum of space-time. Could we ever use it?.The vacuum energy idea goes back to Einstein's GR equations when he added his cosmological term to push against the natural collapsing...

Helio reacted to Unclear Engineer's post in the thread SpaceX could launch 1st Starship to orbit in January, Elon Musk says with
Like.
Still not impressed by the "It'll never work" crowd. They keep neglecting the good points to dwell on the bad points. For example... -
Helio reacted to billslugg's post in the thread Powerful solar telescope unveils ultra-fine magnetic 'curtains' on the sun's surface with Like.
Normally, when I look at vigorous convection it looks like cauliflower tops. These granules are different, more flattened on top. This...

Helio replied to the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone.Thanks. That looks right. Only the "optimistic HZ" equations allow planets 0.97 AU (solar equivalent apoapsis for Kepler-725)...

Helio reacted to rod's post in the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone with Like.
Space.com reported - "The newfound planet, called Kepler-725c, revealed itself only through "transit timing variations."..."Does this...

Helio replied to the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone.Isn’t this more of a super Venus planet? I suspect it never reaches 1 AU at apsis. Also, the greater the ecc., the greater the...

Helio replied to the thread James Webb Space Telescope unveils fiery origins of a distant, hellish exoplanet.Exactly where I was heading. The tidal loading will continue to draw it in. So will it be within the Roche limit when its orbital...
