A spherical shell-like structure 1 billion light-years in diameter named Ho’oleilana is discovered in the distribution of relatively nearby galaxies. We posit this is the 1st observation of an individual Baryon Acoustic Oscillation (BAO).
It’s now thought that they could illuminate fundamental questions in #physics, settle questions about #Einstein’s theories, & even help explain the #universe.
…In recent yrs, the amt of data that scientists have discovered about black holes has grown exponentially.
Look, the Very Large #Telescope has imaged a cosmic #flower! 🌼 The blue "petals" are actually multiple images of the same object, a distant #galaxy seen when the #universe was only 20% of its current age. Light rays from this faraway galaxy were bent by the gravity of a foreground galaxy (the orange one at the centre) creating separate images of the distant source – a so-called Einstein Cross.
Stargate Universe started 14 years ago today on Syfy.
Some didn't like the change of style for Stargate, others (and me) regretted that the second & last season ended on a cliffhanger. In any case, it was the beginning of the end of a golden era for Stargate. #scifi#stargate#universe#syfy#spaceship#destiny
TIL: red dwarfs will be the stars with the longest life of the universe, estimated in trillions of years for the smallest ones.
We are still in the "stelliferous era". What will be the possibilities of life in the hyper-distant future? My favorite speculation, from both scientists and science fiction writers, is that an incredibly advanced civilization would have to create its own universe and tunnel to it. #universe#sciencefiction#scifi
1/2 Astronomers have made the furthest detection ever of a #galaxy 's magnetic field using ALMA.
Magnetic fields affect the orientation of dust grains in galaxies, which then emit polarised light. By studying this polarised light we can reconstruct the orientation of the magnetic fields, shown here as lines overlaid on the ALMA image.
100 years ago tonight, Edwin Hubble made the astronomical observation that definitively established the existence of the #universe beyond our own Milky Way galaxy.
His discovery of a Cepheid variable #star in the Andromeda Galaxy — famously labeled "VAR!" with red ink in Hubble's own hand on the plate — demonstrated beyond a doubt that Andromeda was a separate #galaxy from our own.
If the #universe is #infinite, then you are not #unique An infinite number of you exist, and will be near impossible to distinguish the exact copies of you from those that are just a tiny bit different.
This is my first photo of the Milky Way. I was shocked that the Milky Way can be seen with the naked eye. 🌌 👀 I took the photo in Teide National Park in Tenerife, which is one of the least light-polluted places on earth. Enjoy! I will post more night photos. 😊
While there are many things in life that I care about, the one thing that truly matters is how we treat each other.
If we change nothing more than the self-serving apathy that runs rampant throughout all of our societies, we level up in an indescribable way. The impact would be unfathomable.
Love, kindness, and compassion are literally all we need to change the course of our species and our planet.

I discovered this Wikipedia entry a week ago. I've been reading it once a day since then. It's extremely fascinating.
Could white holes actually exist? (www.space.com)
White holes are mathematically possible, according to general relativity. But does that mean they're actually out there?
How old is our universe? New study says Big Bang might have happened 27 billion years ago (www.usatoday.com)
A study published this week in an astronomical journal suggests our universe could be 26.7 billion years old, or about twice as old as we thought.
