Using data gathered by NASA's Juno Jupiter orbiter, scientists estimate that Europa's ice shell is about 18 miles thick — which could make it hard for nutrients to get down to its buried ocean.

On Feb. 1, the Snow Moon will rise alongside some of winter's brightest stars after drifting past Jupiter

Mercury, Venus, and Saturn put on an early-evening display in the west, while Jupiter dominates the rest of the night. Jupiter features many events involving its four major moons that are well worth chasing down.

"What makes the event even more extraordinary is that it did not involve a single volcano, but multiple active sources."

There’s no mistaking Jupiter in the sky these Butler winter evenings, rising in the southeast as evening twilight ends. In fact, you should be able to easily see it long before twilight fades.

Research into Jupiter’s moons shows Io and Europa did not evolve apart but formed with opposite compositions from the beginning.

February stargazing is so special in Pottsville. Sure it’s cold but the extra special celestial jewels make it worth bundling up for. If you’re not already in the darker countryside, try to get

"Most excitingly, this new idea addresses one of the longstanding habitability problems on Europa and is a good sign for the prospects of extraterrestrial life in its ocean."

Jupiter, the giant planet, appeared to align closely with the full Wolf moon, creating a stunning celestial display visible to the naked eye. The wolf moon is the full moon of January and happened to be the last supermoon in a string of four, meaning it appeared bigger and brighter in our skies next to Jupiter.

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not ...

February stargazing is so special. Sure it’s cold but the extra special celestial jewels make it worth bundling up for. If you’re not already in the darker countryside, try to get out there. But
