Abnormally warm patches of water in the Pacific Ocean have had a disastrous effect on marine life since 2010. Now we may know what’s causing these giant “blobs” to keep appearing. Science Alert has more, including how a policy designed to improve environmental conditions may have negative consequences. https://flip.it/cx7s4L #Science#Environment#PacificOcean
I copied this obituary this morning from the LA Times, just a reminder to everyone that #covid is NOT over. #COVID19#maskup I am not related to this lady, but on this mother’s day please protect those you love. #covidisnotover#covidisairborne#science
Could magma be moving deep below the surface on the border of Germany and the Czech Republic? And if so, what is the significance? Recently installed seismometers in the Vogtland region captured a swarm of earthquakes, suggesting a “complex seismic situation” could be developing. Live Science explains. https://flip.it/xMLNt9 #Science#Earthquakes#Germany#CzechRepublic#Geology
I’m getting SO MANY questions on whether we will see the aurora tonight. The honest answer: I don’t know!! Last night’s activity was really low, but there are several CMEs that will likely hit Earth tonight, so there’s a better chance.
That being said, the level of activity that brought about the aurora as far south as FL/TX/Mexico is higher (G5) than what’s predicted (G4). (1/2)
If you’re north of about Washington DC on the east coast, I would say you have a good chance of seeing them tonight away from light pollution. This is the current forecast, which is more conservative than my prediction.
English chemist Dorothy Hodgkin was born #OTD in 1910.
Among her most influential discoveries are the confirmation of the structure of penicillin as previously surmised by Edward Abraham and Ernst Boris Chain; and mapping the structure of vitamin B12, for which in 1964 she became the third woman to win the Nobel Prize in Chemistry. Hodgkin also elucidated the structure of insulin in 1969 after 35 years of work.
«Une tempête solaire d'une violence inouïe est passée à côté de la Terre en 2012. Elle aurait pu "renvoyer la civilisation contemporaine au XVIIIe siècle" si elle avait atteint notre planète, selon la Nasa»
Aurora colors come from atoms that are trying to shed some of their energy.
In very thin air, oxygen survives in a delicate, high-energy state that emits green light. In denser air, atomic collisions knock oxygen to a lower-energy state that emits red. Nitrogen is a robust emitter that glows bright in even lower, denser layers of the atmosphere.
Scientists may have found a way to make biodegradable plastic from algae, a development that could potentially diminish the harmful effects of microplastics that linger for thousands of years. ABC News reports: https://flip.it/mizbsY #Science#Plastics#Environment
Van De Graaff (VDG) Generator kit - V2 - 150mm - 40,000V of sparky fun.
The 150mm Van De Graaff kit is designed for kids (or adults) to learn about "static" electricity by actually building a working device. A small High voltage generator that will achieve 30,000 to 40,000 volts of "static" electricity. The 150mm van De Graaff generator is a complete Van de Graaff system, comprising of a Polished Stainless Steel Dome, a high speed motor, dissimil... Read More #kits#makers#stem#science
This week on #SETILive, communications specialist Beth Johnson chatted with Dr. Tom Esposito, SETI researcher and Lead of the Unistellar Cosmic Cataclysms program, about the impending nova of T Coronae Borealis and the scientific efforts to catch it!
Do any of you do video editing ... perhaps for a podcast or maybe personal home videos? If so, what is the best, most easily used video editing software out there?
I don't need all the bells & whistles, but will need features like splicing video segments (from diff't sources) together, some nice (not over the top) transitions, ease of use, & good quality end results.
An interesting article on the time line of the universe.
The Universe passed through many epochs, from free quarks and gluons to stable protons and neutrons to neutral atoms to stars, galaxies, planets, and more. The precise time at which these various epochs occurred, including the (current) dark energy-dominated era, can be pinpointed with precision. Here’s how we know.
I’m going to do a longer video/newsletter on this Monday but here is why you might have been seeing the Northern Lights yesterday (and if you’ll see them again this weekend)
