After a career in journalism, local author Rich Bangs has spent the past 10 years creating a sci-fi trilogy exploring extraterrestrial intelligence: "Forgiven," "Forgotten" and …

Our beloved libraries in Littleton, Douglas County and Englewood have stayed in touch, as good communicators should. Curbside service is available and we still await announcements of actual openings of the facilities’ doors as health departments wrestle with the responsibility of keeping us physically safe. Englewood, Littleton and Douglas County have announced curbside pickup at specific times. Call or communicate online with requests: And, note available stories and more online ...

Going Viral, or Not, in the Milky Way - The New York Times
The event was celebrated as the beginning of a new era in spaceflight, with talk of moon colonies, Mars voyages, space tourism, interplanetary capitalism and the cool new SpaceX spacesuits . "We are proving out a business model, a public-private partnership business model that ultimately will enable us to go to the moon, this time sustainably," Jim Bridenstine, NASA's administrator, said at a news conference on May 26.
It was hard not to see it as an ominous signal, reinforcing a message some thinkers say has been sent by the universe regarding our cosmic destiny as a species. In 1998, Robin Hanson , now an economics professor at George Mason University, posed a vexing question: If the universe is such a garden of possibility, as astrobiologists and cosmologists proclaim, why amid billions of worlds and after billions of years is there no evidence of anybody out there to greet us?
Reworking the SETI Paradox: METI's Place on the Continuum of Astrobiological Signaling -
The Search for Extraterrestrial Intelligence (SETI) has heretofore been a largely passive exercise, reliant on the pursuit of technosignatures. Still, there are those that advocate a more active approach.
To escape the SETI Paradox properly defined, at least one technological civilization must choose not to suppress its own continuum of astrobiological signals, of which METI is merely the most effective endmember. Passive SETI's low likelihood of success in the short-term is a serious obstacle to sustainable funding, alongside a 'giggle factor' enhanced by a pernicious fear of contact.
Europa's Dynamic Ocean: Taylor Columns, Eddies, Convection, Ice Melting And Salinity -
Results of 3d simulation. (a) Surface ocean temperature (◦C) as a function of longitude and latitude for a 10 × 10 degree region, showing a highly turbulent flow. (b) Depth-longitude temperature (◦C) sections near the top and bottom of the ocean at the equator, showing downward and upward convection plumes.
Previous studies suggested that Europa's ocean is turbulent, yet neglected to take into account the effects of ocean salinity and appropriate boundary conditions for the ocean's temperature. Here, the ocean dynamics of Europa is studied using global ocean models that include non-hydrostatic effects, a full Coriolis force, consistent top and bottom heating boundary conditions, and including the effects of melting and freezing of ice on salinity.

Reasons NASA's Doug and Bob should probably just stay in space
I am talking about NASA astronauts Douglas Hurley and Robert Behnken, who shot off from Cape Canaveral on the SpaceX Falcon 9 Saturday, then headed even farther in the Crew Dragon capsule. They are doing tests and research and will return to Earth in 100 or so days, when the capsule parachutes into the ocean.
They should reconsider coming back so soon! It is really bad down here. I don't know how this message will get to them — is there Facebook in space? But in case they can check their DMs, here are some reasons they might want to think about staying.
