From NASA We’ve known since the Apollo missions that dust can present challenges for explorers on other worlds. Now, scientists are using instruments on the Perseverance rover to understand the risks of dust on Mars and find clues about how to protect future crews on the Red Planet.

I have been working on visualizing the appearance of proposed space mirrors on the night skies. As the beam approaches it appears as a column of light emerging from the darkness. At the beam center of a 600 km high 54 m. mirror the reflection gives a light similar to that of 38 Full Moons, 9.5 Lux.

Sometimes — EXTREMELY rarely, but *sometimes* — I'm wrong about something. So, mea culpa: yup. There's at least ONE green star. www.scientificamerican.com/article/gree... 🧪 🔭

Another interesting result is that the average white dwarf is, in fact, white, instead of the pale blue that they are usually depicted as 🔭 arxiv.org/abs/2610.18966

Not everything in the Universe glows… Dark nebulae are dense clouds of gas and dust that block light from behind, creating inky silhouettes. 🔭🧪 🔎 A few spooky spots to find in NSF–DOE Rubin Observatory's view of the Trifid and Lagoon Nebulae: 1️⃣ Barnard 85 2️⃣ Barnard 89 3️⃣ Barnard 302 and 303

Added some extra ancillary info and slowed it down....so now you can replay the whole mission over about 27 minutes - www.youtube.com/watch?v=hx8l...

Perseverance has set a new off-world record! 🏅 On Oct. 11, the rover's odometer hit 28.1 miles (45.22 km), eclipsing the distance record set by NASA's Opportunity rover.

As part of NASA's efforts to modernize and unify its websites, the raw image websites (Mars 2020, MSL, Psyche, Cassini, InSight) will be unified into a new tool. This will try to maintain as much compatibility as possible, but there will be some necessary changes.

NEW: On Oct 20, Japan will launch its most audacious space mission. It’s hoping to fly to Mars, land twice (!) on Phobos (“fear”), steal pieces of that alien moon, and bring ‘em home. That’s right: to pull of this heist, Japan must confront fear itself. @science.org www.science.org/content/arti...

So it is somewhat appropriate that for an astronomical-scale MRI we use NIfTI files and a 3D viewer. We already have 7 slices of Maki, Greebo and Luna, and there are more to come. So this is what we got so far for Cas A light echo by JWST 🔭. NASA, ESA, CSA, STScI. more credits in the page below.

A cool behind-the-scenes of the famous 'Hello Earth' photograph from Artemis II. It was captured by a camera mounted to the window of the Orion capsule, so the interior reflected in that window.
