Explanation:
What created this unusual planetary nebula?

NGC 7027 is one of the smallest, brightest, and most unusually shaped
planetary nebulas known.

Given its expansion rate,
NGC 7027 first started expanding,
as visible from Earth, about 600 years ago.

For much of its history, the planetary nebula has been expelling shells,
as seen in blue in the
featured image.

In modern times, though, for
reasons unknown,
it began ejecting gas and dust (seen in red) in specific directions
that created a new pattern that seems to have four corners.

These shells and patterns have been mapped in impressive detail by
recent images from the
Wide Field Camera 3 onboard the
Hubble Space Telescope.

What lies at the nebula’s center is unknown, with
one hypothesis holding it to be a
close binary star system
where one star sheds gas onto an erratic disk orbiting the other star.

NGC 7027, about 3,000
light years
away, was first discovered in 1878 and
can be seen
with a standard backyard telescope toward the
constellation of the Swan
(Cygnus).

Factfulness Rules of Thumb


Source: Gapminder

 

 

This is a very interesting collection — not so much rules, but a checklist of mental models and thoughts to run though as you make major decisions:

“Factfulness is a relaxing habit for critical thinking. It helps you maintain a fact-based worldview. It teaches you how to recognise and avoid the most common ways information gets misinterpreted. . . Factfulness is the skill to recognise the common types of stories that tend to get all the attention because they trigger our dramatic instincts.”

Good advice for everyone.

Europa and Jupiter from Voyager 1

What are those spots on Jupiter?
Largest and furthest, just right of center, is the Great Red Spot — a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini‘s likely notation of it 355 years ago. It is not yet known why this Great Spot is red.
The spot toward the lower left is one of Jupiter’s largest moons: Europa.
Images from Voyager in 1979 bolster the modern hypothesis that Europa has an underground ocean and is therefore a good place to look for extraterrestrial life.
But what about the dark spot on the upper right?
That is a shadow of another of Jupiter’s large moons: Io.
Voyager 1 discovered Io to be so volcanic that no impact craters could be found. Sixteen frames from Voyager 1’s flyby of Jupiter in 1979 were recently reprocessed and merged to create the featured image. About 43 years ago, Voyager 1 launched from Earth and started one of the greatest explorations of the Solar System ever.

Creep by Radiohead, medieval and fantasy inspired

Verily, I am flabbergasted by the response these days of late. Over one hundred thousand souls? Thank ye, from the bottom of my heart.

I now present a morose tune that perhaps we all can relate to. Some of us float like a feather, but at some point or other, we all feel like the creep in the corner. Poor fellow.

The art is a combination of a manuscript margin ornament (I’m sorry, I can’t recall where from), and the little weirdo is a detail from “The Rutland Psalter”.

Lyrics:
When thou wert here before
I could not look thee in the eye
Thou art like an angel
Thy skin makes me cry
Thou float’st like a feather
In a beautiful world
I wish I was special
Thou’rt so very special
But I am a creep
I am a weirdo
What in hell am I doing here?
I do not belong here
I care not if it hurts
I want to have control
I want a perfect body
I want a perfect soul
I want thee to notice
When I am gone
Thou’rt so very special
I wish I was special
But I am a creep
I am a weirdo
What in hell am I doing here?
I do not belong here
She runneth out the door
She runneth out
She run, run, run, run, run
Whatever makes thee happy
Whatever thou want’st
Thou’rt so very special
I wish I was special
But I am a creep
I am a weirdo
What in hell am I doing here?
I do not belong here
I do not belong here

Lyrics:
Robert hath a swift hand
He doth gaze upon the fyrd, and he maketh a plan
He hath a jaunty cap, perched upon his head, he is a longbowman
He did find an old bow of yew
And a quiver of arrows in his father’s chest, wherefore I cannot say
But he cometh for thee, yea he cometh for thee

All ye bully-rooks with your buskin boots
Best ye go, best ye go
Outrun my bow
All ye bully-rooks with your buskin boots
Best ye go, best ye go, faster than mine arrow

Father worketh all day
And he cometh home late, yea he cometh home late
Mayhaps he bringeth me a gift
For stew is in the pot though it doth taste of grit
I have waited e’re long
Now mine eye is quick and mine arm is strong
I reason with my crooked cap
And say “Thou art an artless, greasy tallow-catch.” Yea

All ye bully-rooks with your buskin boots
Best ye go, best ye go
Outrun my bow
All ye bully-rooks with your buskin boots
Best ye go, best ye go, faster than mine arrow
