@caltechipac.bsky.social scientist Catherine Clark was quoted in a @physicstoday.aip.org article about the science behind the book and recently released movie Project Hail Mary.
Check out her quote about Rocky's home planet here:

The dust particles are composed of silicates (similar to beach sand), carbonaceous grains and polycyclic aromatic hydrocarbons and trace the gas distribution in the galaxy. The well-mixed gas and dust provide a reservoir of raw materials for future star formation.

This 8-micron image reveals infrared emissions from hot dust, heated by nearby luminous stars. These dust particles absorb ultraviolet and visible light, re-emitting it as longer infrared wavelengths.

A green-tinted double whammy: it's St. Patrick's Day & #MessierMarathon week! 💚
Messier 81 is a sight to behold in this image from NASA's Spitzer Space Telescope. In the night sky, M81 is visible with binoculars! (but it won't look green like in this infrared image 😉)

This wobbly, energetic black hole is the first of its kind, and its discovery offers new insights into how galaxies evolve:

"It's like seeing 2-year-old children act like teenagers"
Astronomers have captured the most detailed look yet at faraway galaxies at the peak of their youth, an active time when the adolescent galaxies were hastily producing new stars.

NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky!
This is the most comprehensive spectral view of the infrared sky, with 102 colors (or wavelengths) of infrared light from observations made between May and December 2025.

Could a ‘false positive’ planet be hiding a cosmic dance partner? 💃🪩
Scientists recently discovered two planets, KOI-134 b and KOI-134 c. Watch more about this planetary merry-go-round here: youtube.com/shorts/ed3_c...
This giant planet orbiting a tiny star is challenging our current theories 🧩🤔
Planet TOI-6894b is a low-density gas giant with a radius a bit larger than Saturn. The host star is the lowest mass star to have a transiting giant planet discovered to date.

Let the science begin! 🥁
On May 1, NASA’s SPHEREx space observatory began regular science operations, which consist of taking about 3,600 images per day.

Diving more into #BlackHoles!
This movie shows the approach to a black hole surrounded by an accretion disk. Ripples and waves in the disk are caused by turbulent instabilities in the orbiting material, which is hottest and brightest along the inner edge of the disk.

How do physicists visualize #BlackHoles?
This conceptual movie illustrates how light is warped by the gravity of a black hole. Learn more about this visualization here in the caption: youtube.com/shorts/8_srv...
What would it look like to fall into a #BlackHole? Check out this animation!
The light from background stars is warped by gravity, creating the effect of a lens. Light from directly behind the black hole forms an Einstein Ring that encircles the event horizon.

It’s #BlackHoleWeek!
This animation starts just outside the edge of the accretion disk of gas and dust surrounding a black hole. From higher angles, the material looks more like a circular disk as its light is not as strongly bent around the shadow of the black hole.

Anyone hungry for a pizza pie on #PiDay? This galaxy’s warped shape reminds us of pizza dough being flung in the air by a chef! 🍕
Galaxy ESO 510-G13 lies in the southern constellation Hydra, some 150 million light-years from Earth. Read more about it on AstroPix: www.astropix.org/image/stsci/...
An image of galaxy NGC 341 taken in the optical by the Sloan Digital Sky Survey. This image can be found in the NASA/IPAC Extragalactic Datatabase (NED).
How many digits of Pi do you know? 3.14...how about galaxy NGC 314? Check it out on the NASA/IPAC Extragalactic Database for #PiDay2025! NED is like Google for the sky, especially for objects outside the Milky Way, and one of IPAC's many science data archives.
