SEPTEMBER DEEP SKY OBJECT PROPOSED:

NGC 7331 in Pegasus is an unbarred spiral #galaxy 40M light-years distant.
It's size is similar to our Milky Way and has several galaxy satellites around,
It's a good target for visual/CCD amateurs.

Neanderthals were the main hominin specie in Europe and N Asia for hundreds of thousands years. 
Last searchs say they dissapeared about 40.000 years ago but some continued living until 28-35.000 years ago in Gurham cave in Gibraltar.
The last ones!

When we speak about microbial life in Venus we refer to life in top clouds not in its surface where the temperature is about 450 celsius, the atmospheric pression 90 atmospheres and probably rains sulfuric acid.

The Sculptor Galaxy, NGC 253, is an starbust intermediate #spiral #galaxy, currently undergoing a period of intense star formation. 
It's 11 million lightyears distant, not a far distance astronomically speaking.

Incredible image of #Jupiter made by the Hubble Space Telescope (HST) last August, 25th.
Incredible colour, details and... you can see also the moon Europa at left. 
Wonderful ! https://t.co/t4L9Gs1wD9

Andromeda Galaxy 📷 PRADES (Tarragona). This spiral galaxy lays around 2,5 million light years away from us. Because of its size and distance from our Milky Way, Andromeda is approaching us at a speed of 110 km/second (being a blue shifted object).The resulting galaxy - MILKOMEDA https://t.co/ZJgjxEqnn6

Let me introduce you a wonderful #galaxy “not far” from us: M31 Galaxy. This amazing image was done by Aleix Roig an expert amateur member of @AstroSabadell association and @astroprades https://t.co/9urmXfjvMq

Examples of many heroes in the fight against COVID:

Li Wenliang, a Chinese doctor who died after treating patients. Accused of "spreading rumors" for warning of danger

Yolanda Fuentes, director of Health of Madrid Region, refused to reduce the anti-covid measures and resigned https://t.co/VW98od4EYO

Brown dwarf:
Is it possible to detect a #BrownDwarf #star with an amateur telescope?
It's not easy, but YES !: 
The brown dwarf "Teide1" barely detected by Xavier Bros. Image from #Anysllum #Observatory @AstroSabadell.
It is the barely noticeable point at the top of the line. https://t.co/SLjlBfEVYj

#BrownDwarfs are objects less massive than small #stars and more massive than big #planets. 
They have #atmosphere and clouds according last studies like this one of Etienne Artigau (Montreal): https://t.co/JyPA6nV21C

Clara Sousa-Silva: 

"If there is life on Venus we should not bring it to Earth. These would be life forms that have adapted to live in a very hostile environment and are probably very toxic and dangerous for us"

Clara Sousa-Silva, member of the team that discover the gas on #Venus's clouds: 

"The question is whether the phosphine detected is due to an exotic geochemical phenomenon that we do not know about or the presence of life."

Beta Lyrae is a multiple star. One star hides the second one and both are surrounded by an accretion disk formed by mass transfer between them.
Light variations are easy to observe; this light curve was made by me only with binoculars and visual brightness measurements. https://t.co/ecsdu6FHdT

Tell us what's your opinion: Are there microbial life in Venus's clouds?

If microbes in Venus’s clouds were confirmed -in an unknown future-this would be wonderful news because means basic life is able to start and develop in bizarre ecosystems and could be common in the Universe.
