Helio replied to the thread JWST spies frigid alien world on bizarre orbit: 'One of the coldest, oldest and faintest planets that we've imaged to date.Yes, and if it is aligned to the galactic plane, it's likely much harder to find as well. 15 AU isn't all that unusual of a distance... -

Like.
Space.com reported, "But, unlike the flat, well-ordered orbits of planets in our solar system, the 14 Herculis system is dramatically... -
Helio replied to the thread Coating satellites with super-black paint Vantablack could help fight light pollution crisis.Has black paint be used in the past? Yes it has. Black paint does, admittedly, absorb light but it is a far better radiator as well...

Helio replied to the thread Coating satellites with super-black paint Vantablack could help fight light pollution crisis.The problem has been overexposure of images by bright satellite streaks. Dark streaks would have no effect for the long exposures.

Helio reacted to Unclear Engineer's post in the thread Astronomers see the 1st stars dispel darkness 13 billion years ago at 'Cosmic Dawn with Like.
But redshift and lower density did not happen faster than light can be absorbed. And from what I have read, the CMBR frequency...

Helio replied to the thread Astronomers see the 1st stars dispel darkness 13 billion years ago at 'Cosmic Dawn.This topic is often poorly explained and I still don't have a clear understanding of how we see light from the earliest moments...

Helio replied to the thread Astronomers see the 1st stars dispel darkness 13 billion years ago at 'Cosmic Dawn.Good catch. The article seems false here. The Dark Ages following the first Reionization (CMBR light) came as a result of the newly...

Helio replied to the thread A hidden 'super-Earth' exoplanet is dipping in and out of its habitable zone.Yeah. “Earth-like” is a stretched term to represent the likely orbital environment for an exo about the size of Earth. The advance in...

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...
