You've probably heard that "we are stardust," but this graphic breaks it down further & tells you what kind of stars your dust came from--and which elements didn't come from stars at all.

Meanwhile, far from Earth...
The space between stars is full of gas and dust that is normally dark & invisible to us. But a flash of light from a 350-year-old supernova has lit up the interstellar medium -- revealing it in all its strange, swirling glory.

PRESS RELEASE: A research team led by Dr. Sofia Sheikh of the SETI Institute, in collaboration with the Characterizing Atmospheric Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to answer a simple question: If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away? https://youtu.be/Pdg2x3NP2ds
I loved working on this article:
The technology in your cell phone has a hidden connection to the stars. Modern computer chips are made using ultraviolet light from vaporized balls of tin--and those balls closely mirror the physics of supernova explosions!

Hey, a graphic novel I worked on is out! Check out Space Chasers by astronaut Leland Melvin, Joe Caramagna & Alison Acton! It's the first in a series of middle grade books about a team of brilliant kids who become astronauts + have an amazing adventure. I loved working on this series so much. 🚀💫

Here it is: The first clear image of an eclipse of the Sun by the Earth, taken from the surface of the Moon.
This is what last night's lunar eclipse looked like from the Blue Ghost lander's perspective on the Moon. Amazing!

The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.
\[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]
Inverse Fourier Transform:
\[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\]
The equation allows us to listen to mp3s today. Digital Music Couldn’t Exist Without the Fourier Transform: http://bit.ly/22kbNfi

I'm making a pilgrimage to 3 great observatories in Chile's Atacama desert (ALMA, CCAT, and the Simons Observatory). It's a trip I've dreamed about for years. Will try to post updates as I go.
Just getting there--from Santiago to Calama to San Pedro--is spectacular. Such raw geology.
On this #FlashbackFriday look back at the historic solar storm of May 10th last year, a rare, magical alignment of Big Dipper with the dazzling Corona Borealis.

I want to give #Mastodon a proper go this time, but it's hard to connect with people when no-one follows you, and hashtags only get you so far. 😞
So, if you like one of the hashtags below, please consider following me, and if you do, I'll follow you back! Thank you. 💗

After Two SpaceX Explosions, U.K. Officials Ask FAA to Change Starship Flight Plans
—
Facing a significant increase in the number of SpaceX launches, British officials detailed their concerns about the safety of Turks and Caicos and other Caribbean territories after debris from an earlier failed launch littered beaches and roads.

I recently visited the ALMA observatory in Chile. While I was poking around the telescopes, ALMA researchers released amazing new views of planet-forming disks around young stars.
These are the most detailed images yet of new solar systems being born.

In 1950, A Shockingly Dark Sci-Fi Adventure Tried To Predict The Space Race
Rocketship X-M, quickie ripoff of Destination Moon. Astronauts discover Martian civilization destroyed by nuclear war, leaving behind mutant cavemen. Many science flubs. Even more numerous sexist remarks. Still, better than expected, enhanced with special effects shots added in the 1970s.

You only die twice:
Recent theoretical models suggested that some stars could destroy themselves in two, successive supernova explosions. Now we have direct visual evidence that such doubled stellar deaths really happen.

A massive spherical bubble, 11, 46, or 157 light-years across (they aren't sure yet)
Could be from a white dwarf slurping up a companion star, exceeding a mass limit, and exploding
