Jupiter Probe's Encouraging Signals and Successful Repairs

The JUICE spacecraft, on its way to Jupiter, has captured its first ultraviolet views of the cosmos, revealing a streak of the Milky Way filled with shining stars from the southern sky. The images, although not spectacular, indicate operational progress. The spacecraft's Ultraviolet Spectrograph (UVS) instrument collected its first set of data, confirming its performance. JUICE's mission is to study Jupiter's icy moons, suspected of harboring subsurface oceans and potentially habitable conditions. The UVS instrument, developed by the Southwest Research Institute, captures ultraviolet light to measure the concentrations of elements and molecules in the moons' atmospheres. JUICE is expected to reach the Jovian system in 2031.

Southern Skies Light Up as Comet C/2021 T4 Lemmon Passes By

Comet C/2021 T4 Lemmon, a long-period comet discovered in 2021 from Mount Lemmon Observatory, is currently sweeping through the southern skies. It will reach perihelion on July 31, 2023, and will be at conjunction behind and north of the sun on November 9, 2023. The comet's brightness and tail size predictions can be unreliable due to the melting of ice and release of dust in these spinning objects. Alan Hale, discoverer of the great comet Hale-Bopp, alerted us to this comet with a Facebook post on May 22.
