Mirroring our #PaleBlueDot, the view of a remote set of pixels moving around their star.

A few seconds of animation took years of observations (2003 to 2020):

Auf Phoenix verwirft #Kepler gerade die kreisrunden Planetenbahnen. Und die Erde bewegt sich um die Sonne!

Good morning! 😀

Today's astro image is of Kepler-452 b, first near-Earth-sized world to be found in the habitable zone of star similar to our Sun.

Kepler-90 is a Sun-like star 2,545 light-years from Earth. Just like out own Sun, it has a system of eight planets.

Here's an artist’s concept of the Kepler-90 system compared with our own solar system.

Nog twee planeten gevonden net voor het einde van de Keplermissie

Astronomen hebben waarschijnlijk de laatste planeten gevonden die ooit door Kepler zijn ontdekt. Ze zijn gevonden in gegevens die zijn genomen terwijl de ruimtetelescoop letterlijk op zijn laatste benen liep.

Other new #music from today? New #MusicVideo from Kep1er for their Japanese song "I Do! Do You?"

It's a cute track. I liked it. The MV was extremely high school...but that happens.

Aardse exoplaneet gevonden op 72 lichtjaar afstand

Een internationaal team van astronomen die op zoek zijn naar transiterende exoplaneten (degenen die vanuit ons perspectief het gezicht van hun gastheerster kruisen) heeft zijn nieuwste ontdekking gedaan: een object ter grootte van de Aarde op slechts 72 lichtjaar van ons verwijderd.

https://www.kuuke.nl/aardse-exoplaneet-gevonden-op-72-lichtjaar-afstand/

#astronomie #exoplaneet #Kepler #K2-415 #TESS #transitiemethode

Using data fron #Kepler and #TESS satellites astronomers have discovered a new hot Earth-sized #exoplanet located about 70 light years away from the sun around a low-mass M dwarf #star.

The newfound exoworld, designated K2-415b, is estimated to be three times more massive than the Earth, but this estimate has a high uncertainty and Earth-like compositions cannot be ruled out.

Paper by Hirano et al. (2023):

I was able to massively improve on yesterday's rendering of one #Kepler's representation of the #PlatonicSolid of Earth. Done in #Blender using hair curves for the grass.

I redid the grass with fewer control points (down from 8 to 3), then reduced the spline resolution from 12 to 3, and reduced the resolution of the profile curve from 12 to 2. Using some napkin math, each blade of grass was about 4608 verts before, and is now 72 now, so I could add 64 times as many blades as before.

A rendering of one #Kepler's representation of the #PlatonicSolid of Earth. Done in #Blender using hair curves for the grass.

Really feeling the limits of my hardware on this one. Blender crashed 4 times due to me running out of memory, and I had to make my grass way bigger than I wanted. There's probably a more optimal way I missed.

A transparent version will be posted in the replies when it's finished rendering.

"I much prefer the sharpest #criticism of a single #intelligent man to the #thoughtless #approval of the masses.”

#kepler #quotes

I've spent most of the evening reading (translated) extracts from #Kepler's various works.

The other-worldliness and sheer fantastical quality of his theorizing, far beyond what one might imagine from the platonic solids model of the solar system, it never ceases to amaze me. And yet, such things he discovered in his attempts to empirically confirm these hare-brained ideas, the core of which he never abandoned!
