General Science Thread: Larger Hardons and Gravity Wobblers

[6souls]

So apparently an announcement is happening today that says strong indications of life were found in venue's atmosphere.

Or Venus

the RAS is live now talking about this, it's pretty interesting.

edit- this is the paper that was published by Dr. Greaves and her team on this, figured BG's science nerds might like to peruse it, it's probably the most excited i've been to read a science paper in a while lol https://www.nature.com/articles/s41550-020-1174-4

I had read the paper cited as reference 10 and found it pretty interesting. Not surprised there is an application for it already.

I read the full paper. It is very interesting and very robust. I fall on the side of this being an unknown chemical process rather than a biosignature (in this specific case of Venus) for reasons noted by the authors (see below). This is really cool though. ALMA continues to amaze. Expect follow-up observations to happen and more info within a year or two after all the data is reduced.

There’s just too many really good reasons why life on Venus, even just at a cellular level, is highly unlikely. This is very much not my field though and I only have been tangentially involved with 2 astrochemistry papers so anything above the basics goes into the “I’ll trust the chemists on this one” bin. So, from the discussion in the paper I want to highlight this:



Regardless of whether or not this has anything to do with life on Venus it is really cool that we are constraining detections of PH3 because ref. 10 DOES make a really good case for it being a valid biosignature for rocky exoplanets and JWST SHOULD be able to detect it easily if it ever fucking launches.

What’s up with all these videos about large meteor showers or whatever it is.

[Andalusian girls]

well deserved for Doudna (and Charpentier), overdue even

[Andalusian girls]

chemists prolly pissed tho

Star dies by "spaghettification" as it's consumed by supermassive black hole

Astronomers have witnessed an extremely rare occurrence: the end of a star's life, as it's obliterated by a supermassive black hole. And this particular star's collapse was even more unique, because it experienced death by "spaghettification" — and no, that's not science fiction.

According to a new study in Monthly Notices of the Royal Astronomical Society, astronomers at the Zwicky Transient Facility spotted a blast of light, known as a tidal disruption event, that indicated the star's death in September 2019. Researchers said this week that it was the closest such a phenomenon has ever occurred to Earth, taking place just over 215 million light years away.

This is not the first time this has been observed but it is the closest. The amount of data gathered from this would likely make even a veteran Astronomers head spin.

Moon has a lot more water than once thought, studies show

Gotta watch Goldeneye now

The central instrument platform fell down. Guess they called it just in time...cables didn't hold out much longer.

Ars has video footage of the collapse. They actually had a drone at the top of one of the towers, doing cable inspection, when it let go. Pretty impressive.

Maybe 'dark matter' doesn't exist after all, new research suggests
Observations of distant galaxies have seen signs of a modified theory of gravity that could dispense with the invisible, intangible and all-pervasive dark matter.

Wtf is this shit?! So I have literally wasted years of my life reading about Dark Matter?
