The Trappist Family of Planets has a hard core!

Trappists

In February of 2017, a team of European astronomers announced the discovery
of a seven-planet system orbiting the nearby star TRAPPIST-1. Aside from
the fact that all seven planets were rocky, there was the added bonus of
three of them orbiting within TRAPPIST-1’s habitable zone. Since that time,
multiple studies have been conducted to determine whether or not any of
these planets could be habitable.

What’s up with the boring names?

I propose we call them Liesl, Friedrich, Louisa, Kurt, Brigitta, Marta, and Gretl. The most habitable is Kurt, because he’s so magnetic.

But the star, of course, is Maria.

Buh-DUM-dum.

Full Metal Asteroid! Um. Maybe.

Psyche

“Final planning stages” usually translates into “we have no idea when, if ever, this thing will work.”

Psyche!

Yes, actually.

Let’s hope NASA doesn’t resort to this:

Vulcan does not exist — but 40 Eridani does

June 13, 2019

As a kid I remember reading about “Vulcan,” which people used to think existed between Mercury and the Sun but always orbited on the opposite side.

Completely fictional, of course.

But…

Vulcan made a comeback as the fictional home of Spock in Star Trek. It was said by Star Trek creator Gene Roddenberry to be orbiting around 40 Eridani (also called HD 26965), a triple star system in the constellation of Eridanus “the river” in the southern hemisphere just 16 light years distant. In September 2018, astronomers at the University of Florida in Gainesville found a “super-Earth” exoplanet orbiting exactly where Vulcan was said to be.

There is only one logical conclusion…

The Moon is a Shining Ball of…uh…Nickel?

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground…”

Uh. OK. That’s a LOT of metal. Nickel and iron? Ancient asteroid impact? 300 kilometers deep?

Sounds like a “golden” mining opportunity…

…even enough to totally justify “the Moon is a part of Mars“?

Interstellar Travel Tech — oh, Really?

Interstellar

“It is time to venture beyond the known planets, on toward the stars.”

Yes, I agree, but I don’t see how any of the ideas in this article will help us achieve that goal. I think the problem is the reliance on conventional means of propulsion. Clearly some sort of bending of space/time is needed to leave the solar system faster than, say, a decade, let alone reach other star systems.

Dawn already used an ion engine (way too slow). The solar gravitational lens is neat but it won’t take us there physically. The “space-based laser” idea is funky but impractical.

Getting off Earth should help (Moon Base, Mars, somewhere else like Triton). Escaping our own planet’s gravity well takes way too much effort. But after that, it’s time to forget about rockets and start thinking of truly “wacked out” ideas.

For starters, Discover, how about dumping your absolutely awful page design? Yeesh, this page is hard to read.

No “Planet McPlanetface” option. Sorry.

The three choices fit IAU naming regulations and are associated with mythological creatures and figures that reflect aspects of 2007 OR10’s physical properties, which include rock, water ice, possibly methane ice, and a surface that’s red in color.

Your three choices?

Gonggong (共工, the bringer of floods 洪 and chaos)

Holle (which I always thought was Hulda or Holda)

Vili (which I knew as Wela in English class)

At least these scientists learned an important lesson from our recent past…

First ever black hole image (not counting Disney)

“What we see is larger than the size of our entire Solar System,” he said.

“It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe.”

So this demonstrates two things.

One – Einstein was right (when wasn’t he, at this point).

Two – We need a Disney remake.

On to Triton. With Trident. Finally.

We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an “ocean world” with liquid water — and maybe even harbor life.

And now, pending approval, we might soon get our best glimpse yet. NASA’s Jet Propulsion Laboratory proposed on Tuesday [19 March 2019] at a conference in Texas to send a spacecraft called “Trident” to Triton — with the goal of sussing out whether it’s a habitable world.

A low-cost mission that would give us decent photos and even video of Triton, Io, and even Venus. Let’s do this.

Bennu’s Intergalactical Glitterspray Show!

OK, not actually glitterspray. Lots of tiny moons. Micromoons?

Exploding out of Bennu, which is an asteroid circling way out near Pluto right now, but will intersect Earth’s orbit in September 2060. And in 2135. And in 2175. And maybe soon again after that.

Doomsayers, prepare yourselves!

(Cumulative 1 in 2700 chance it’ll hit Earth by then. Too bad Bruce Willis won’t be around to save us.)
