An old refractor telescope sees a second life under the night skies, thanks to the efforts of a dedicated amateur observer.

Elon Musk and Jeff Bezos may harbor multibillion-dollar dreams of sending millions of people to live on Mars, on the moon and inside free-flying space habitats — but a newly published book provides a prudent piece of advice: Don’t go too boldly.

I know for a fact it’s one of the most annoying things that can happen.  I’ve done it lots; whether that be out at night with telescope or a bit of DIY but for sure it has to rate as one of the most frustrating things to happen. I am talking of dropping something you are using. Ranking high is dropping tools while you are actually using them..  Dropping a tool is one thing but imagine dropping an entire bag of tools, while in orbit!!!! Oops!

We live in an age of exoplanet discovery. One thing we’ve learned is not to be surprised by the kinds of exoplanets we keep discovering. We’ve discovered planets where it might rain glass or even iron, planets that are the rocky core remnants of gas giants stripped of their atmospheres, and drifting rogue planets untethered to any star.

NASA’s Juno mission continues to orbit Jupiter, gathering data on its atmosphere, composition, gravitational field, magnetic field, and radiation environment. This data is helping scientists to learn more about the planet’s formation, internal structure, mass distribution, and what is driving its powerful winds. Periodically, the spacecraft also performs flybys of Jupiter’s largest satellites (the Galilean Moons), acquiring stunning images and vital data on their surfaces. These include optical and thermal images of Io’s many active volcanoes, Europa’s icy terrain, and infrared images of Ganymede.

A study published today in The Planetary Science Journal examines how NASA’s James Webb Space Telescope (JWST) has conducted a first-time detection of carbon dioxide in a Centaur, this one designated 39P/Oterma. A Centaur is a small planetary body that orbits between Jupiter and Neptune and frequently crosses the orbits of one or more of the gas giant planets within our solar system. While no Centaur has been imaged up-close, they typically exhibit a combination of attributes between comets and asteroids. While carbon monoxide has been detected in two known centaurs, this recent discovery could mark a turning point in how scientists understand the formation, evolution, and composition of not only Centaurs, but of the early solar system, as well.

When the Universe erupted into existence with the Big Bang, all of its matter was compressed into a tiny area. Cosmologists theorize that in some regions, subatomic matter may have been so tightly packed that matter collapsed into primordial black holes. If these primordial black holes exist, they’re small, and they could be hiding among the population of free-floating planets.
