Sorry, there’s no “Planet X”

This doesn’t exist, but it’s a cool drawing.

Critics of the Planet Nine claim said the apparent clustering of the discovered TNOs might only be because that’s where telescopes were looking or were most sensitive.

If you are looking to find evidence to prove your theory, it’s much easier to find what you’re looking for.

You should instead try to find evidence to disprove your theory, and then ask at least two more people you don’t know (or even better, generally disagree with) to try to find evidence to support your theory.

“Seek and ye shall find” is a terrible way to support a claim. Have the courage to challenge your beliefs.

Also, it’s Planet X, not 9. Pluto is a planet. So there, Neil deGrasse Tyson. :-p

Maybe there is Hope, after all

Congratulations, UAE! The Hope Probe (al-Amal) successfully entered Mars orbit on February 9th.

Made in the US (Boulder, Colorado) and the United Arab Emirates (Dubai) and launched from Japan, it shows what hat can be accomplished through international cooperation instead of competition.

Maybe it is truly Hope, after all, and not just for Arab states.

Sorry, Venus is just a lot of gas

There’s a reason I didn’t post a while ago about the supposed “there’s life in the clouds of Venus” finding.

It was just a big load of gas.

Sorry, folks. Venus is a big rotten egg. 🥚

Magnetic reconnection plasma thruster: Not too fast, not too slow, juuuust right

February 4, 2021

A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.

Looks good so far…

…although it’s just a computer simulation right now and the magnetic thruster model hasn’t even been built yet.

Ah, well, just repurpose an existing ion thruster, right?

Hmm. I’m not a rocket scientist, but.. 🚀

Yet another conjunction of the Moon, Mars, and, uh…

Hey, everyone! If you look up at the right time, you can…

Uh. Yeah, anyway.

Tardigrads…In…Space…I mean, On the Moon…

December 28, 2020

Despite the impact, scientists believe that if anything survived the crash intact, it may well have been the tardigrades. The microscopic creatures were sandwiched between micron-thin sheets of nickel and suspended in epoxy, a resin-like preservative that acts like a jelly — potentially enough to cushion their landing.

I, for one, look forward to our lovably cute waterbear overlords…

Amateur Thai astronomer photographs unknown Sungrazer

This family of comets originated from a large parent comet that broke up into smaller fragments well over a thousand years ago. The sungrazers continue to orbit around the sun today.

Now this is something I didn’t know. Learn a new thing ever day…

A sneak peek at the inside of the Red Planet

Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.

Lots of small “Marsquakes,” but nothing big. Max M4.5.

A techtonically silent world. Might explain the weak magnetic field which allowed solar winds to rip off its atmosphere long ago.

Solar System Likely To Disintegrate Sooner Than Earlier Predictions

December 7, 2020
MThomas

Note: Not to scale (thanks, NASA)

“As per the new simulations, it will take 100 billion years for any remaining planets to run off across the galaxy, leaving the dying Sun far behind.”

Pack your bags, folks!
