Planetary Nebula Mz3: The Ant Nebula
Why isn't this ant a big sphere? Planetary nebula Mz3 is being cast off by a star similar to our Sun that is, surely, round. Why then would the gas that is streaming away create an ant-shaped nebula that is distinctly not round? Clues might include the high 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star visible above at the nebula's center. One possible answer is that Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holds that the central star's own spin and magnetic field are channeling the gas. Since the central star appears to be so similar to our own Sun, astronomers hope that increased understanding of the history of this giant space ant can provide useful insight into the likely future of our own Sun and Earth.

On the Chernobyl disaster

Hello! While your post was largely an average, brief overview (as many are - and for very convenient reading!) there was a slight piece of misinformation that I’d really like to address. It’s very common and appears on most research anyway, but is a longstanding slight misconception.
While there were nineteen deaths following beyond that thirty (composing of on-sight staff and disaster relief workers at the scene post-failure), through almost any research, they were never directly tied to the incident. This is the Soviet Union we’re talking about, I will allow that, and information is… mottled. It’s hard to find reliable sources on every documented case simply because not every case was reliably documented. Still, there has yet to be a concrete link between many others dying as a direct result of this. Check out all the Thyroid Cancer cases and their background, it’s really interesting, but still unreliable as evidence, given that it’s safe to assume at least a portion of them were caused by the screening process or a false diagnosis.
Resettling was necessary, but recently Belorussians have been resettled in one of the former hazard areas and they’re working on continuing this well into the future and reclaiming their land. Scientists have done a lot of observation and research on Pripyat (I recommend watching this video to see how nature has reclaimed it!) and Chernobyl itself. A lot of what they’ve found is really interesting, as well, especially some of the semi-old findings on birds and fungus in the area.
Which brings us right into how this disaster affected Europe. “It is estimated that all of the xenon gas, about half of the iodine and caesium, and at least 5% of the remaining radioactive material in the Chernobyl 4 reactor core (which had 192 tonnes of fuel) was released in the accident. Most of the released material was deposited close by as dust and debris, but the lighter material was carried by wind over Ukraine, Belarus, Russia and to some extent over Scandinavia and Europe.” (Iodine and caesium have a half life of about eight-ten days, after eighty-ninety days there is no longer a radioactive threat contained within the composite.) 137Cs, now that is something that has a thirty year lifespan, amplified further by the amount of it. (1 gram of 137Cs = 3.214 terabecquerels of radiation
A becquerel is the equivalent radiation of one neutron decaying per second.)
But. It also has a biological half life of seventy days, so the immediate threat from that became more quickly restricted to the direct hazard areas within Chornobyl. Even now, some of the debris around the reactor are solids from the incident (if anyone is interested in the solidifying process of certain radioactive material, throw an ask my way), but most of them have been appropriately collected and disposed of, thankfully.
The “lighter material” (gaseous and inactive fluids, mainly) was also caught in plant life, roof shingles, noxious smog, rain, so on and so forth. The real percentage of it that was on breathing level outside of the immediate hazard zones was quite small and largely inconspicuous. No reports of acidic rain, ashen clouds, or cancers that can be attributed to the incident in the rest of Europe have turned up in my research. I wouldn’t call that “radioactive smoke,” either, considering most of the radioactivity stayed behind in chunks and denser particles. There were still concerns and complications, but radioactivity works like that; ground zero and no man’s land are always the most aggressively contaminated, but beyond those areas the activity tends to gradually mellow. But what does it all mean?!
Well, friend, it means the tiniest bit of misinformation is still misinformation and builds into common misconceptions, which can be harnessed for worsening shock statements. Something so common and trivial hardly irks me, but providing further information on this disaster and following it is something I think matters. Especially with how hard it can be to get reliable sources. Citations:

“Hello Girls,” as American soldiers called them, were American women who served as telephone operators for Pershing’s forces in Europe. The women were fluent in French and English and were specially trained by the American Telephone and Telegraph Company. In 1979, the U.S. Army finally gave war medals and veteran benefits to the few Hello Girls who were still alive.
OVNI filmado perto de vulcão em erupção no Chile
Uma mulher filmava a erupção de um vulcão no Chile quando também registrou um OVNI que apareceu nas proximidades.
O vulcão Calbuco no Chile entrou em atividade na quarta-feira à noite, pela primeira vez em 42 anos, e tem bombeado para fora grandes quantidades de cinzas vulcânicas sobre algumas cidades pouco povoadas.
Na tentativa de capturar imagens do espetáculo, uma mulher também conseguiu registrar algo inesperado pairando no céu nas imediações da nuvem de cinzas – uma aeronave não identificada com duas luzes piscando que então desapareceu em uma fração de segundo, sem qualquer explicação.
O vídeo, desde então, acumulou mais de 315 mil visualizações. Alguns usuários da internet têm especulado que o objeto poderia ter sido um helicóptero tentando filmar a erupção mas seu súbito desaparecimento continua a trazer um pouco de mistério para a história.

Youth Tobacco Use: Results from the 2014 National Youth Tobacco Survey
We are committed to a science-based approach that addresses the public health issues associated with tobacco use. That’s why we are collaborating with CDC on the only nationally representative survey of middle and high school students that focuses exclusively on tobacco use – the National Youth Tobacco Survey (NYTS). The CDC’s NYTS was designed to provide national data on long-term, intermediate, and short-term indicators key to the design, implementation, and evaluation of comprehensive tobacco prevention and control programs

April 26th 1986: Chernobyl nuclear disaster
On this day in 1986, a reactor exploded at the Chernobyl nuclear power station in Ukraine, creating the world’s worst nuclear disaster. Radioactive smoke was let into the atmosphere which spread across the Soviet Union and Europe. Thirty-one members of staff and emergency workers died directly due to the accident, but many others died from diseases - often cancer - brought on by exposure to radiation. Hundreds of thousands of people eventually had to be evacuated and resettled due to contamination of areas of Belarus, Russia and Ukraine. The disaster raised questions of the safety of nuclear power and encouraged the Soviet government to become more open. Only two nuclear accidents have been classified as level seven on the International Nuclear Event Scale - Chernobyl and the Fukushima Daiichi disaster of 2011.
“For the first time ever, we have confronted in reality the sinister power of uncontrolled nuclear energy.”
