“We together flew on Mars. We together have our Wright brothers moment.”

Yeah, yeah, I know. Technically, a German immigrant in Connecticut flew a plane before Orville and Wilbur.
But PR counts. Kudos, NASA!

Using blobs of skin cells from frog embryos, scientists have grown creatures unlike anything else on Earth, a new study reports. These microscopic “living machines” can swim, sweep up debris and heal themselves after a gash.

The possibilities are endless…

The gag practically writes itself…
…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.
And no, it’s not really pink. That’s just a Chandra X-ray image.
Shame, really.

Hazardous asteroid!? Call out Bruce Willis!
No worries. “Close to Earth” in this is 1.25 million miles. But it’s a great chance to find out more about the early solar system.

“Many people in the field of science are aware of the Alcubierre Drive and believe that warp drives are unphysical because of the need for negative energy,” said Alexey Bobrick, scientist and astrophysicist at Lund University, according to a press release. “This, however, is no longer correct.”

There can be only response to this news…

Great job, NASA! Landing on Mars is always a tricky business.
Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.
Piece of cake, right?

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

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.

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. 🥚

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.. 🚀
