A SASSy find, no doubt. The paper show kinematic simulations of the 3 initial SASS stars based on their current orbital parameters. Their orbits vary from circular to highly elliptical. In general the disk stars form from cold gas clouds which by their nature of being cooled has assembled in...

There is an ongoing discussion within astrobiology, mainly because planned Mars crew missions means putting a huge source of contamination there. As for the dangers to Earth biosphere - or vice versa - they are likely low since populations are adapted to their current environment. Of course...

Outstanding questions: Which SLS version can deliver 25 mt to TMI? Current SLS block 1 can deliver 20 mt to TMI. https://ntrs.nasa.gov/api/citations/20205007434/downloads/SLS-PlanetaryDecadal-FINAL-LRP1 091420.pdf Is a 25 mt Mars EDL possible? Current massive lander was 1/10th that or a 2.4 mt...

Starship grows on you. 🙀 Which organisation? SpaceX is private and works for itself, FAA is federal and works for the state. This isn't Russia (say).

This result was in the sky since the first team used only one data pipeline for analysis, despite that it is know that they may give different results depending on noisy data.

It could have been worse, some would have written μT as 'MT' (megatesla). The unit is "tesla" by the way, the international SI measurement system spells it newton et cetera to not confuse with historical persons (Tesla, Newton).

The kerogen cycle of sedimentary organic material compression and heat conversion has long been known to produce most of modern Earth's natural gas deposits. Coal mining show the fossils and the associated oil/gas production. The atmospheric methane has today mostly industrial but still a hefty...

The NASA article by Lonnie Shekhtman is a bit more informative: https://science.nasa.gov/solar-system/planets/mars/why-is-methane-seeping-on-mars-nasa-scientists-have-new-ideas/

Gaba-domains, from cell receptors? This makes no sense, and it furthermore looks like an software c&p of terms. I reported all 3 such comments as self promoting spam under the guise of comments or suggestions of "journals". If it has any merit it could stand for itself and specifically for...

Not the normal antimatter production. The observed photon density of the cosmic background radiation neatly fits the expectation from a Standard Model CP asymmetry breaking, such as is possible in the neutrino sector. (We'll know within a decade, from neutrino oscillation observations.) Yes...

Less speculative than your personal opinion of it, if you read the paper. The same goes for observed dark matter and dark energy in general, but for reasons of too many independent observations to convince scientists that these things do not exist. So why shouldn't we accept that, they are the...

It is an interesting result, that tidal interaction with normal matter should be able to capture and thermalize dark matter so prodigiously. The self annihilation requirement is having a modicum of “Majorana” particle character mixed in with the normal “Dirac” particle character. The mix...

Nice save! They do a lot of good science there and on Moon and Mars. They even aim to return Mars rocks before NASA/ESA who fumbled on the ball (well, NASA did).

*Applause* indeed, thanks to the Voyager teams for the hard work!

Finally finding some actual utility for SLS while it is still operational.
