Some Galaxies Have Extremely Bright Cores, Suggesting That They Contain A Supermassive Black Hole That

Yes! It’s not ~very~ legal, but I think this is very important to know if you gonna do research.

I also read somewhere saying that if you have this kind of issue and you aren’t really in a rush, you could reach out to the people that did the research and ask them for the article! We all have the same problem with publication sites and most people just want their research to be known and cited. They would love to help you too, we’re all scientists after all. I, personally, haven’t tried this yet since I’m currently not doing any research, so I’m not 100% sure about the success probability. But hey, it worth a shot I have to say.

I havent seen anyone talk about this yet so im making a post. 

So lets say you’re researching something for a paper (or just for fun) and the research paper you want to read is behind a paywall, or the site makes you create an account first, or makes you pay to download, or limits you to only 5 free articles, or otherwise makes it difficult for you to read what you want.

do not fear! copy the link to the article

go to sci-hub.se         (the url is always changing so its best to check out whereisscihub.now.sh to find what the current url is)

slap the article link in there

bam! free access!

An asteroid the size of a skyscraper should pass near the Earth on August 10th

Near Earth Asteroid

An asteroid 570 meters in diameter is expected to approach 8 million kilometers from our planet on August 10. The situation is of no concern to NASA specialists, who stress the large number of similar celestial objects that are spotted each year near the Earth. The space agency says it fears more those who are not listed.

According to NASA, an asteroid the size of a skyscraper will pass near the Earth on Saturday, August 10. Called “2006 QQ23”, the celestial object is approximately 570 meters in diameter and its trajectory will place it at a distance of 8 million kilometers from our planet, closer to home, says CNN. A “more or less benign” situation for experts from the American Space Agency. This asteroid is of a “moderate size” Lindley Johnson of NASA’s Global Coordinating Office for Defense says the asteroid is “of moderate size” and explains that half a dozen similar-sized aerolites are approaching each year. Not to mention that the solar system includes nearly 900 of a volume greater than that which advances towards the Earth. The specialists are therefore reassuring.

They explain having already studied the movements of “2006 QQ23” since the year 1901 and until 2200. Because a possible impact between the Earth and a foreign body of this size would cause significant damage over a large area . Even if this scenario occurred, NASA would then be able to launch a space mission to deflect the celestial object. When it comes to asteroids, “it’s the ones we do not know about that worry us,” says Kelly Fast, also a member of the Coordination Office.

The Earth from Russia’s Elektro-L satellite

This image compilation, comprised of images taken by the Russian Elektro-L weather satellite, was taken from a geostationary orbit at a distance of 36,000 km. It shows the changing illumination of Earth as it rotated on the autumnal equinox and illustrate the concept of a geostationary orbit. At this height, the satellite is orbiting at fast as the earth is spinning and stays in the same location relative to the surface of earth.

Hello there

As you can already tell, I haven't been really active (at all) on this account. The reason for this, to be honest, was the fact that Tumblr became stale to me, and besides that, I was very busy with my study for the university entrance exam for a year.

All of this caused this account to be abandoned for 2-3 years, which really not what I wanted at all because I created this account to help people with study and have reliable sources of information.

But I'm back (yay), and I’m trying to get back and resurrect this account again. There will be a few changes (since I changed a lot in the last few years).

1. My love for science is still there and even stronger now because... *drum rolls*... I’m studying science at university now! More specifically, biotechnology major, planning on an immunology minor. So yes, besides primary astronomy contents, I'm planning on posting more biology stuff! 

-> The name of this blog changed: study-astronomy-ref to study-astronomy-biology-ref

2. If you don’t know, this account is member-based. Even though I will be more active in the next few months, I can't be 100% be sure about keeping the account active for too long because of personal jobs and study. I had recruit more members for this account a while ago, but it didn't end well.

-> So if anyone wants to contribute to this blog as a pure studyblr, message, please. There, of course, will be standards and I will select the best people to run this blog smoothly, educationally and actively. For the best to everyone!

3. To me, this account is for people (very communism). So besides the science news, findings and study references, slide in the DM if you want something more interesting on this blog (science art? some Q&A? other cool science stuff?). I would be very happy if this blog could reach more people with similar interest and it could be a fun, wholesome and interesting place for anyone that has a passion for science and study! Wooray!

Maybe that's all I have to say. Stay tuned for more contents!

Head up to the sky, aliens. Keep on curious.
