First, to answer the question: A clock on the Moon is faster by 57 microseconds per Earth day. (See https://www.newscientist.com/article/2437577-time-ticks-faster-on-the-moon-by-57-microseconds-per-earth-day/ ) So, that is a ratio of 1.00000000066 Moon Time to Earth Time. It seems odd to me...

And there is this interesting article about present day bacteria that can only survive in colonies: https://www.space.com/space-exploration/search-for-life/this-strange-bacteria-aligns-to-earths-magnetic-field-and-needs-friends-to-survive . It looks like a step on the way from individual cells...

While not fundamentally disagreeing with Contrarian, I want to point out that "extinction events" have had a substantial influence on the evolution of life on Earth, rather than completely ending all life. A challenging environment might actually be a necessity for the development of...

I doubt that the majority of readers of Space.com believe that we are "alone in the universe". You do not have to believe that in order to not believe Dave, who believes not only that there is other intelligent life, but that it is here, hidden, watching us, and our governments do know that...

It would be nice if articles such as this about Axiom missions to the ISS included some additional info about where the Axiom space station project stands in its goal to attach to the ISS, build out, and detach to make it an independent commercial space station.

While I basically agree with the need to make realistic press releases and have "news" media that tries to convey the truth without hyping things - that clearly is not how societies actually operate. And, most of us are used to it, by now. News media need to make money, which they do by...

More likely a Saturn-like ring of tiny particles, as the first inadvertent collision leads to a cascade of collisions and a ring of space junk.

Dave's insistence that his beliefs are true blinds him to the other possibilities that might be the actual truth - and interferes with others' efforts to discover the real truth. Science demands logic and verifiable facts. Statements that theories are true without those underpinnings are...

Nice to read about real successes in space exploration. Hoping this continues on an annual frequency.

So far as I have read, nobody has reported "spacecraft" defying the laws of physics. The reports have involved unexplained sightings of things in the atmosphere, with assumptions that they have entered the water at times - none in space. So, the assumption that they are spacecraft seems to be...

I think the first question is what is the "land" on Titan composed of, compared to its liquid methane "rivers" and "oceans"? Deltas are formed with materials eroded from "land". And, the second issue is that delta's form on the submerged, gently sloping parts of continents. On Earth...

I am not sure what the "massively empty wrt its environs" means. There is a lot of conjecture, because we are not able to closely inspect even the things we can see, such as White Dwarf Stars and Neutron Stars. So, much of their properties are based on subatomic physics experiments and...

Wouldn't quarks have gravitational attraction? If not, and neutron stars are on the verge of becoming quark-gluon stars, so black holes are even more likely to be such, then I would expect black holes to loss their mass, lose their gravitational effects, and release everything inside as...

The idea that "dark matter" is composed of extremely light particles that have quantum effects on the macro scale of galactic dimensions seems worthy of study. However, I think theories like this about how that could explain the observed deviations of the LCDM model from observations is really...

And there is also this theory: https://www.space.com/the-universe/black-holes/ultralight-dark-matter-may-have-helped-monstrous-black-holes-form-in-the-early-universe . On the other hand, how about a theory that has "primordial" black holes being created at the observed sizes? It seems to me...
