NASA Juno Takes First Images of Jovian Moon Ganymede's North Pole

Infrared images from Juno provide the first glimpse of Ganymede's icy north pole.

These images the JIRAM instrument aboard NASA's Juno spacecraft took on Dec. 26, 2019, provide the first infrared mapping of Ganymede's northern frontier. Frozen water molecules detected at both poles have no appreciable order to their arrangement and a different infrared signature than ice at the equator.

First Ever Image of a Multi-Planet System around a Sun-like Star Captured by ESO Telescope

The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a star similar to the Sun. The observations can help astronomers understand how planets formed and evolved around our own Sun.

Sea-level charting satellite passes with flying colors

Like students all over the world currently awaiting exam grades, the Copernicus Sentinel-6 Michael Freilich satellite has also been put through a series of strenuous tests leaving the eyes of the teams involved in this international mission set firmly on its final results. Happily, Sentinel-6 has passed with flying colours and engineers can now prepare it for shipment to the US for liftoff on a SpaceX Falcon-9, which is scheduled for 10 November.

Scientists Discover That Volcanoes on Venus Are Still Active

New 3D model provides evidence that Venus is churning inside

1_10_0.jpg
The 3D rendition above shows two coronae observed on the surface of Venus. The ring-like structures are formed when hot material from deep inside the planet rises through the mantle and erupts through the crust. Research by UMD’s Laurent Montesi found that at least 37 coronae on Venus represent recent geologic activity, including the one named Aramaiti, seen on the left in this image. The black line represents a gap in data.
