President #JimmyCarter created this message to travel on Voyager 1. It's still out there traveling at 40,000 mph, looking for a cosmic community to catch it and play the media.

Quick reminder that NASA currently has a solar sail in Earth orbit, flapping its wings in the flow of sunshine.

Astronomers from The University of New Mexico, along with U.S. and international researchers, have confirmed the existence of a new giant exoplanet, made possible through a collaboration with citizen scientists around the world.
Several key programs enabled this global effort, including the TESS Follow-up Observing Program Sub Group 1, the Unistellar Citizen Science Network, and the TESS Single Transit Planet Candidate Working Group.
PRESS RELEASE: https://www.seti.org/press-release/seti-institute-strengthens-science-advisory-board-five-new-members
The SETI Institute welcomed five new experts to its Science Advisory Board (SAB), broadening its scope in important scientific and ethical domains essential to understanding life and intelligence in the universe. The new members bring expertise in science communication, ethics and philosophy, animal cognition and intelligence, analysis of extraterrestrial materials, and planetary astronomy.
Two unusual things happened on Earth around 460 million years ago: a bunch of asteroid impacts near the equator & an intense global cold spell.
Possibly both were the result of an asteroid that broke up & gave our planet a pretty but deadly set of rings.

Are the colours in astronomical images real? What do these colours mean? And what about images that aren't taken in visible light?
We get these questions all the time, so in the latest episode of Chasing Starlight we show you how these colourful images are made:
IFT-6 orbital test flight is NET November 18, 2024.
Local launch window opening at 1600. Allows for Ship 31 to flip and land in daylight in the Indian Ocean.
Raptor relight added as an objective (needed to prove the upper stage can do a safe orbital insertion and de-orbit). Booster 13 will attempt RTLS and landing at OLM 1 just like Booster 12.

This may be the strangest planet yet discovered. It seems to be a Pluto-size world circling the remains of three dead stars: two white dwarfs & a pulsar, as massive as the Sun but no bigger than Brooklyn.
If confirmed, it would also be the smallest exoplanet known.

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.
