The metric does not measure what it is claimed it does, and even if it did it would be meaningless for assessing the role of Dr. Kate Bouman in creating the image. I'll go on to why, but I first want to draw particularly attention to the fact that Dr. Bouman has explicitly rejected the idea that she deserves sole credit:
But Dr Bouman, now an assistant ...
Is Neil Tyson's claim that the Gregorian calendar is the “most accurate calendar ever devised” true?
The Gregorian calendar qualifies as "most accurate" if one defines "most accurate" as a calendar that has a leap year every four years except for years that are divisible by 100 but not by 400. Tyson didn't mean that. He made it ...
Technically, that is the percentage of the code she contributed, 2410 lines in 90 commits.
But that tells us nothing about what the code does. Andrew Chael, the man who is credited with doing the work in that article, has spoken up against the rhetoric used against her.
The claimed detection of phosphine is not conclusive evidence of life on Venus; it simply indicates that there are unknown chemical pathways on the planet that are producing it. While these may be biological in nature, they also may not be. Therefore, the discovery might be evidence of life on Venus.
Recent work has cast serious doubt on all of this, ...
The claims are two wrong, one sort of correct
Before we start, it might be worth noting though that a strong magnetic field is more likely to keep radiation out than letting it in (*).
Anyway, the Earth's magnetic field at the surface, measured in nanotesla, and sourced from here. The image below has the locations in question marked with yellow stars (thank ...
There are many reasons why this is wrong. The first one is the assumption of 1 supernova per 25 years. That was the value arrived at in Gustav Tammann's article published in 1970. Others got values up to 100 years (Tammann himself changed his value later). All these values are really only good guesses.
Worse errors are made in the percentage of remnants ...
Their claim is incorrect. On an astronomical scale, one kilometer is a very small value. In fact, Earth's orbit regularly varies by far more than 1km.
According to the NASA's Solar System Exploration website's facts and figures,
Metric: 147,098,291 km
Imperial: 91,402,640 miles
Scientific Notation: 1.47098 x 108 km (0....
That little outfit called NASA says this:
The Persian Calendar, also known as the Iranian Calendar, is made available in a similar fashion for it is the most accurate of calendars. These calendars are included for the millions of people who use them regularly.
But this is quite complicated, as the term "accuracy" for a calendar might mean quite ...
Yes, there was a famous narrowband signal detected in 1977, which became known as the "Wow! signal". Whether it came from outer space is unknown.
The original astronomer wrote a 30th Anniversary Report on the signal in 2007, which covers a lot of the technical details.
Wikipedia adequately covers the topic.
Brian Dunning of the Skeptoid Podcast examined ...
The Goldilocks zone ("Circumstellar habitable zone") is a real thing:
In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, colloquially known as the Goldilocks zone, is the region around a star within which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their ...
Is there any evidence other than this to back it up?
A Gallup poll in 1999 found that 18% of Americans thought the Sun revolves around the earth.
So there is support for the notion that substantial numbers of people in the US hold this belief.
A 2005 EU survey is reported as finding that a higher percentage of Europeans held the same view.
The sample ...
The old title asked "Did researcher Katie Bouman only contribute 0.26% of code that created Black Hole image," and the existing answers do a good job explaining why it isn't true and why lines of code aren't a useful metric. The new title, however, asks "Was credit for the black hole image misappropriated?" and the correct answer should appear rather ...

You can see some pixelization happening at the very bottom and top of the moon. Another dead giveaway is the fact that the moon in the image is full for the entire month, ...
People have stepped on the Moon when they went there and left footprints, so we've plenty of photographic evidence of their footsteps on the Moon.
In fact, it turns out that people do leave footprint in dust, even if they weigh less, like a child leaves footprints on Earth while weighing as much as a man on the Moon.

The majority of the Earth's iron was around when the planet formed. Calculations of the mass deposited by subsequent impacts show that these impacts were comparatively insignificant in changing Earth's iron levels, making the claim false. Additionally, those impacts came from bodies originating within the Solar System - not around other stars.
In the ...
This works, but there is one detail missing, and depending on your latitude the picture could be misleading. The sun moves approximately one finger width across the sky each 15 minutes, but the sun does not necessarily set vertically down onto the horizon. You have to use your hand to measure the distance the sun has to travel along it's path, ...
It's a fair statement to make, even if not true (and especially not when taken out of context).
From the context it's apparent that he meant predictive calendars in widespread use. Also one can imply that fairly simple rules can be qualification needed for everyday use.
I think it's obvious that with today's knowledge of mathematics and physics even the ...

Any strong claims made by news outlets are journalistic rather than scientific.

This appears to be a myth that has been repeated in the media. White it is true that whale and sperm oil have been used historically as lubricants, modern synthetic replacements exist from a variety of manufactures to include the Nye Lubricants that is mentioned in various articles as being a provider to NASA of lubricants.
At least three articles have ...
Likely close to that much, yes.
We don't know the precise amounts of these trace precious metals in Psyche, merely that the main constituents are nickel and iron.
Our understanding of the amounts of gold and platinum in asteroids derive largely from studying meteorites, which should be representative of asteroid compositions.
Given those assumptions, Psyche ...
Basically, Tyson's claim is roughly true considering that more accurate alternatives in actual use are either:
observation-based, i.e. tweak the calendar at is goes (current Persian i.e. Solar Hijri calendar), or
purely predictive, but diverge from the Gregorian one well in the future:
Milanković's (="revised Julian') diverges in the year 2800 (making it ...
No, that isn't exactly what Stephen Hawking said.

The mass of the Earth is approximately 5.98×10²⁴ kg. In bulk, by mass, it is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%); with the remaining 1.2% consisting of trace amounts of other elements.

Probably not. According to 'Monster' solar eclipse takes on Asian giants , referring to the 22 July 2009 solar eclipse, which had over 6 minutes of totality:

These pictures are ostensibly made by using a head-mounted light as well as a secondary light pointing toward the camera.

The quote in the OP from the creation article is an accurate summary of a mainstream Science Daily article: Big Bang's Afterglow Fails Intergalactic 'Shadow' Test:

Nuclear fusion is the mechanism by which most atom nucleii have been formed from the original plasma present after the Big Bang. It requires incredibly hot temperatures not found in outer space. Since the Big Bang, nucleii have been formed in stars and then ejected in outer space at the end of the life of those stars.
