The IAU famously decided that Pluto is not a planet any more, calling it a "dwarf planet" instead, along with Ceres. However, their definition works as well as it does only because of a historical accident of our solar system and the bodies we have discovered in it so far. There are good reasons for thinking it has a "use before" date too, as we'll see. We don't know when that date is, but we will probably reach a point where we can't use it any more, at some point in the next two or three decades. The "use before "date may well be sooner than that. So why not change right away?

This is an article by the space engineer and Mars colonization enthusiast Robert Zubrin, The Planetary Protection Racket claiming that we don’t need to protect Earth from Mars microbes or Mars from Earth microbes. This is not the first time he has said controversial things like this, and they are not taken seriously by the planetary protection experts. Let’s go back to summer 2000, when he put forward similarly forceful arguments in print that there is no need to protect Earth from Mars microbes

This is what he wrote back then:

I’m getting messages from scared people today. The fearmongers and charlatans are saying that a giant planet Nibiru is going to appear during this solar eclipse and is due to hit Earth or do a devastating very close flyby 33 days later on September 23. No! This is total BS and nonsense promulgated by people who couldn’t predict the date of a solar eclipse or where to watch it if their life depended on it.

To everyone who is still scared today - nothing is going to happen I assure you. It's just a shadow. You are getting scared of a small shadow 70 miles wide passing briefly over the surface of Earth. Meanwhile you experience an average of twelve hours of darkness every single night.

This is another of my "Doomsday Debunking" articles, using science and astronomy to debunk some of the crazy modern myths about the end of the world.  This time it's the idea that the eclipse of the sun on 21st August in the US is a "sign" that the world is about to end. If you are an astronomer or scientists you will just LOL at this for sure. But for some people this fear is like a living nightmare for them. They contact me, extremely scared that the world is, literally, about to end because of this eclipse. They probably flunked maths and physics at school and just don't have the scientific and astronomical background to evaluate it.

With all the tense situation about North Korea, I thought I should do a new post about the situation there. I'm doing this as part of my "Doomsday Debunked" articles I do to help people who are often very scared that the world will end in one way or another. First this is not a risk of global nuclear war. It’s nothing like the Cuban missile crisis. There we had two major powers facing each other on a hair-trigger. And each had the capability of destroying the other’s military capabilities.

Have you wondered why we can't see the Apollo landing sites from Earth? Moon is so far away that even the ISS at around 108 meters in length would span just over one pixel if Hubble were to photograph it on the Moon at its highest resolution. From NASA:

Can Hubble see the Apollo landing sites on the Moon?

No, Hubble cannot take photos of the Apollo landing sites.

“An object on the Moon 4 meters (4.37 yards) across, viewed from HST, would be about 0.002 arcsec in size. The highest resolution instrument currently on HST is the Advanced Camera for Surveys at 0.03 arcsec. So anything we left on the Moon cannot be resolved in any HST image. It would just appear as a dot.”
