I make the world's only binoculars designed for stargazing. You can 3D print and build your own @analogsky.bsky.social / https://analogsky.co/ Also graphic designer for the Terre Haute Gunblades.

Follow Venus the next few mornings, and you can see an unusual sight, as the planet transits (passes in front of) the open star cluster Messier 44 (Praesepe) in the heart of the constellation Cancer. Brilliant -4 magnitude Venus nicks the +4th magnitude cluster on Sunday, Monday and Tuesday morning.

I designed the biggest binoculars in the world (that you can buy) and they're for looking at outer space 🔭 🌌. Early access is a big step for our nano-scale mom-and-pop business to bring this model to life! www.analogsky.co/bloom

World's Biggest Binocular Telescope Model. 8" / 200mm Binoculars — Analog Sky

Analog Sky Bloom 8" reverse Newtonian binocular telescope gives you the most immersive views of the cosmos. Smart electronics combine with thoughtful design to create a whole new stargazing experience...

Big telescopes belong on Earth! A thrilling day for astronomy and humanity. Amazing what public funding can do. Where are the privately-funded pictures like this?

NSF–DOE Rubin Observatory@vrubinobs.bsky.social · last yr.

The image offers a stunning variety of objects — from bright stars ranging from blue to red in color, to nearby blue spiral galaxies, to distant red galaxy groups — demonstrating the broad range of science made possible by Rubin data ✨🔭🧪

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry. Throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

Just thinking of the Harvard computer women a century ago, who looked at images of the universe like this by eye to make discoveries. They revolutionized astronomy, and Rubin definitely will too! Also, wow how excited would Henrietta Leavitt and Williamina Flemming be to see this! 🤩 🔭🧪🎢

I just got an email saying the embargo is lifted, so here's the full @vrubinobs.bsky.social press release: noirlab.edu/public/news/...

Mercury's elongation (distance from the Sun in the sky) is large enough for safe viewing before sunrise. Fun thing to see if you have to be awake in the morning

...and the show’s not over. Tomorrow sees one more chance to glimpse the slim crescent Moon just 36-24 hours prior to New as it slides by Mercury low in the dawn sky. You’ll need a clear, open horizon to the east, and binoculars (and an alarm clock!) will be a plus.

The American Astronomical Society — the largest organization of professional astronomers in the country — has put out a statment about Trump's proposed fatal cuts to NASA science. aas.org/press/aas-st...

AAS Gravely Concerned About Cuts to NASA Science Funding  | American Astronomical Society

The American Astronomical Society is gravely concerned about the deep cuts to NASA science funding reported to be in the draft President’s Budget Request for Fiscal Year 2026.

Just reposting this so it's easy to find later to show my 12-year-old daughter. Sometimes I'm embarrassed I was so excited about the internet as a teenager in the 90s thinking we could share the collective knowledge of humanity when this was pretty much the whole point the whole time.

W-W says Meta let advertisers know when 13-17 y-os were feeling depressed saying, this is a good time to try to serve them an ad. "If a 13-year-old girl would delete a selfie that was considered a good time to try to sell her a beauty product. This was taken as a signal and shared with advertisers."

👇The Mars #EuropaClipper gravity assist is happening right now! Locate Mars to wave at Clipper as it flys by on its 5yr journey to Jupiter & the frozen ice moon of Europa. At the moment Mars is an easy-to-spot triangle with the bright Gemini stars of Castor and Pollux! 🔭🧪🛰️ ℹ️ stellarium-web.org

🔊It's gravity assist day! Today Mars will bend the #EuropaClipper trajectory towards Jupiter. At 17:57(UK)/12:57(EST) 🛰️Clipper will be just 550 miles above Mars’ surface, testing its thermal imager & radar.

Little closer on the 50mm stargazing binocular update, amidst the new eyepieces launching next week and the 200mm stargazing binoculars. The right-hand side is pretty much ready to print. Haven't decided yet if I'm going to NEAF.

We're almost there on a prototype for the updated 50mm binocular telescope (Magic 2). Rack and pinion focuser works great, image merging works great, and now adding built-in PiFinder. PiFinder uses a camera to figure out what you're looking at in the sky without a phone, 20 times a second. The

Prototype 50mm binocular telescope side view. Testing tomorrow. There are about a dozen features here that nobody's done before. Dramatically simplified construction while increasing precision, usability, and image quality.
