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!

SETI Institute In the News: January Roundup 2026
This month’s stories highlight how SETI Institute scientists combine rigorous analysis with curiosity, whether working alongside citizen astronomers, refining the identification of technosignatures, or improving the precision of radio observations that underpin both astrophysics and the search for extraterrestrial intelligence.

#PPOD: This very impressive, and little-known, image of a meandering squiggle of high-altitude clouds on Saturn was captured by the Cassini spacecraft on July 18, 2010. It almost looks like one of these fancy latte art designs! Credit: NASA/JPL-Caltech/SSI/CICLOPS/Jason Major
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

Neue Folge! Heute sprechen wir über euer Feedback zu den letzten drei Episoden. Es geht um uralte Sterne und warum die wirklich bis fast zum Schluss nur Helium erbrüten. Und es geht um die Entstehung unseres guten alten Mondes und ob der Tathergang nun wirklich eine Theorie ist oder eher eine Hypothese. 🤔🌛✨

For the first time, scientists have detected the wind from a black hole.
New images show the supermassive one at the center of our galaxy is puffing away, clearing out a void about 20 trillion miles wide.

On Wednesday, June 17, skywatchers in San Jose will have the opportunity to witness a rare celestial event: the waxing crescent Moon occulting Venus. During a lunar occultation, the Moon passes directly in front of a planet, causing it to disappear from view and then reappear later from behind the lunar limb. Venus is bright enough to be visible in daylight, making this one of the few planetary occultations that can be observed before sunset. The Moon will be a thin, 11%-illuminated waxing crescent. Venus will disappear behind the Moon’s dark limb and reappear near the bright, illuminated edge of the crescent Moon.
This is among the last favorable Venus occultations visible from North America until the end of the decade.
Where to look: Look almost due east at midday. The Moon will be high in the sky (at an altitude of roughly 33 degrees).
When to look: For San Jose, the event occurs in broad daylight:
11:35 am Venus disappears behind the Moon
12:10 pm Mid-occultation
12:46 pm Venus reappears from behind the Moon
Duration of occultation: 71 minutes
Crucial Safety Warning
Because this event occurs during the day, the Moon and Venus will be relatively close to the Sun in the sky. Never look directly at or point a telescope/binoculars near the Sun without specialized solar filters, as doing so can cause permanent blindness. Find a viewing spot in the shadow of a building or a tree to completely block out the Sun while keeping the Moon in view.
After sunset, the show continues. The crescent Moon and Venus will remain close together low in the western sky, with Jupiter and Mercury nearby, creating an attractive grouping.

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.

In a recent SETI Live conversation, SETI Institute Artist-in-Residence (AIR) Director Bettina Forget spoke with Cosmic Consciousness residency artists daniela brill estrada, Bart Kuipers, and Julie-Michèle Morin about Exoplanetary Poetry, an art–science collaboration that asks whether molecules themselves might function as a universal language.

The moon landing conspiracy theory seems like old intrigue, but it’s estimated that as many as 10% of Americans still don’t believe we landed on the moon. We consider why the “moon hoax” belief has been difficult to shake on the latest Big Picture Science.

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. 😞
