“After Euclid’s lifetime, it will just be floating in space. What if future beings found Euclid? How would they know anything about the humanity of the people?” – Tom Kitching, lead scientist of Euclid’s VIS instrument.
This Week's Sky at a Glance, July 1 – 9
The Moon waxes across the evening sky from Leo to Scorpius. The five-planet lineup in the dawn is now four. And amateur astronomers plan to be recording as Saturn's hazy moon Titan occult a star about as bright as Titan itself for most of North America.

Tidal Heating Could Make Exomoons Much More Habitable (and Detectable)
Within the Solar System, most of our astrobiological research is aimed at Mars, which is considered to be the next-most habitable body beyond Earth. However, future efforts are aimed at exploring icy satellites in the outer Solar System that could also be habitable (like Europa, Enceladus, Titan, and more). This dichotomy between terrestrial (rocky) planets that orbit within their a system’s Habitable Zones (HZ) and icy moons that orbit farther from their parent stars is expected to inform future extrasolar planet surveys and astrobiology research.
Red Supergiant Stars Bubble and Froth so Much That Their Position in the Sky Seems to Dance Around
Making a 3D map of our galaxy would be easier if some stars behaved long enough to get good distances to them. However, red supergiants are the frisky kids on the block when it comes to pinning down their exact locations. That’s because they appear to dance around, which makes pinpointing their place in space difficult. That wobble is a feature, not a bug of these massive old stars and scientists want to understand why.
US Space Force establishes new unit to track 'threats in orbit'

This is How You Get Multiple Star Systems
Stars form inside massive clouds of gas and dust called molecular clouds. The Nebular Hypothesis explains how that happens. According to that hypothesis, dense cores inside those clouds of hydrogen collapse due to instability and form stars. The Nebular Hypothesis is much more detailed than that short version, but that’s the basic idea.
Live coverage: Countdown begins for Atlas 5 launch from Cape Canaveral
