New Calculated Trajectory for the Apophis asteroid

AI Thread Summary
NASA's updated calculations indicate a significantly reduced probability of the Apophis asteroid colliding with Earth in 2036, dropping from one-in-45,000 to approximately four-in-a-million. This change reflects advancements in computational techniques and new data availability. Some participants in the discussion noted that presenting odds as four-in-a-million may sound more alarming than one-in-250,000, suggesting a strategic choice in communication. Questions were raised about NASA's methodology and whether initial estimates were overly cautious for publicity purposes. Overall, the consensus is that the risk of an encounter with Apophis is now considered extremely low.

That's Good News!

"Updated computational techniques and newly available data indicate the probability of an Earth encounter on April 13, 2036, for Apophis has dropped from one-in-45,000 to about four-in-a million."

Any particular reason NASA scientists can't reduce their fractions?

Does it just sound like better odds than 1-in-250,000 :smile:

Haha I was thinking the same thing my math teachers would have a hayday if they saw this!

but to the general population saying something has odds out of a million normally indicates that it's going to be an EXTREMELY RARE AND DEFINITLY UNLIKELY event that you shouldn't run out to bet on. :P
 
I like the 4 in a million way of describing it. That's 4x more probable than two one-in-a-million events: being electrocuted by lightning or dying of male breast cancer.
 
Anyone know what kind of Factor of Safety NASA uses in their calculations?

In the article it seemed as if all initial probabilities are on the very safe side. Are they just trying to scare us so they get a little publicity. I mean their intial calculation was 1-45,000 now it's 1-250,000??
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
