Short summary - the risk from larger asteroids of 1 km upwards, large enough to have some global effects is more or less retired as a result of astronomical searches for the last few decades. There is still a risk from smaller asteroids, but in most cases we’d be able to deflect them if necessary, or evacuate the area. The chance of dying from an asteroid is tiny, far less than the risk of dying of lighning.

20 - 40 METER ASTEROIDS ARE TINY - JUST LARGE ENOUGH TO GET THROUGH THE EARTH’S ATMOSPHERE

An asteroid 20 meters in diameter hits every 80 years or so. Since only 1% of the Earth is urban that means around 8,000 years between impacts on an urban area.

Coverage began at 2 p.m. Eastern (7 p.m. UTC). Landing started about 40 minutes later, the entire landing telemetry was streamed live through the briefcase sized Mars Cube One interplanetary "cube sats", and at around 3.01 p.m. EST they got first confirmation of the landing. First image from the surface arrived several minutes later, relayed through the cube sats, and the landing went without a hitch. See the timeline here NASA Landing on Mars milestones

Many journalists have penned exaggerated, click baity but inaccurate articles about the IPCC report on climate change. One of the worst is the one published in the NY Times. It doesn’t have that many out and out mistakes, but it is a highly respected source, and so its mistakes, particularly the confusion of carbon costs and carbon pricing, and not being clear about what happens in 2040, in 2075 or 2100, confused many people.

This is running as a scary story in the more sensationalist science outlets. Dark matter barely interacts with matter and if they are right we are right in the middle of it already. It can’t do any harm. It’s been doing this for all of human history and more.

It's not even like a wind. Not even like the pressure of light. It's like nothing at all.

Nothing to worry about for us. It's pointing in the wrong direction to ever harm us with the gamma ray burst jet. Their best fit model is that it is angled at 30 degrees to the line of sight.

It is too far away from us anyway at 8,000 light years. And there are no gamma ray burst candidates close enough to harm us. I go into that in detail in my article:

But this would be seriously bad news for any living beings that are on stars right close by within a few light years especially, along the line of the jet. Up to 50 light years away, it would cause significant effects on a planet like ours.

This is a very bizarre click bait title from the NY Post that is scaring people. There is nothing here to worry anyone. It is not true at all,even the article itself says nothing about the planet exploding. Just some journalists inventive idea about a way to get people to click on the title?? Fake news. But the research is interesting, an interesting puzzle
