This is a three hour long #photo sequence I took in Jan 2019 during a total lunar #eclipse at ESO's Paranal Observatory in #Chile
As the #Moon moves into the Earth's shadow it becomes red. When sunlight passes through the Earth's atmosphere, blue light is scattered away more efficiently than red light, which passes through almost unimpeded, like at #sunrise or #sunset.
From the Moon, you would see the Earth surrounded by a golden fiery ring.

Want to become part of #ESA's science advisory structure?
The ESA Director of Science invites scientists affiliated with institutions in the ESA Member States to express their interest in being a member of the Space Science Advisory Committee (SSAC), Astronomy Working Group (AWG), or the Solar System and Exploration Working Group (SSEWG):

Phew! Thanks to new data from ESO's Very Large #Telescope, we now know that a white dwarf that was set for a close encounter with our Solar System in 29000 years isn't actually headed our way. Turns out that the intense magnetic field of the #star had biased the previous measurements of the approach speed. You're welcome everyone! 😉
We tell you everything in our latest ESO #blog: https://www.eso.org/public/blog/rogue-star/

Happy Halloween 🎃
Here are the pumpkins I carved this year: An active red dwarf star and its gas giant planet. I call it an exo-pumpkin.

I love also Olympus and Arsia Mons on the Terminator!

In related news, I wrote my thesis in Word 98 and the next version refused to open one of my chapters for no obvious reason.
Plain text and openly documented image formats are definitely the way to future proof your work.... #astrodon #opensource #openscience #TeXLaTeX
For my first year seminar I am asking the students to build and use an astrolabe. It is a great way to both get a physical understanding of the sky, and to really appreciate the sophistication of early astronomy.
The astrolabe was used for centuries to tell the time, navigate, etc. Now you can make and use one too by following the instructions here:

That oxygen you breath? That comes from dying massive stars, ending their light in a supernova.
The iron in your blood? Some massive stars dying, but mainly white dwarfs, the leftovers of dwarf stars like our own Sun, exploding.
The gold ring on your finger? Mostly merging neutron stars, leftovers from supernovae.

What you see here is a pillar of dust and gas sculpted by the intense radiation of stars further up, outside of the field of view.
