Astronomers searching for a hypothesised large planet in the outer solar system far beyond Pluto stumbled across 12 previously undetected moons orbiting Jupiter, pushing the giant planet’s total to a record 79.
Friday, 27 July sees the second total lunar eclipse of 2018, which also happens to be the longest of the 21st century. Observers in Antarctica, Australasia, Russia, Asia, Africa, Scandanavia, Europe, Central and Eastern South America will see the event. The Moon rises at mid-eclipse as seen from the British Isles, some 6 degrees north of Mars at opposition.
It’s holiday time again and the keen observer is faced with the usual dilemma: how does one carry a telescope small enough to be useful to far-flung dark and exotic skies? Fortunately for globe-trotters concerned about optical size and weight, Telescope Service in Germany has the TSAPO60 — a compact and very versatile photo-visual 60mm f/5.5 ED refractor.
Messier 94, a relatively nearby galaxy, features two distinct rings of star formation, the result of pressure waves sweeping outward from the core. This 2015 image from the Hubble Space Telescope shows the galaxy’s inner region and starburst ring.
