Space Photos of the Week: Jupiter Takes One Hell of a Selfie
The Juno spacecraft recently completed its ninth orbit around Jupiter and returned images of the planet’s cloudy, cyclone-studded southern hemisphere.
Saturn’s moon Enceladus is well known for its active plumes, and scientists just got a little closer to understanding what might be fueling them. A loose, porous core could be the answer. Gravity tugs at Enceladus as it orbits the ringed planet, creating friction and heat in its core that could power hydrothermal activity at the moon’s surface.
This series of images captured by the Hubble Space Telescope shows the “light echo” left behind by an exploding white dwarf. The white ring is light leftover from the star that is bouncing off a cloud of interstellar dust some 300-1600 light years away from site of the explosion.
The pockmarked moon Pandora orbits Saturn near the planet’s F-ring, creating small kinks in its shape. This was the final photo taken of Pandora by the Cassini spacecraft before it plunged into the planet on September 15th.
Last week NASA’s Solar Dynamics Observatory spotted a rare circular filament protruding from the sun. These filaments are made up of charged particles that are tethered to the star by a magnetic field, and usually take the shape of long strands. Circular filaments like this one have only been spotted a few times before.
The dust surrounding stars like W Hydrae, seen here in an image taken by the ALMA Observatory in Chile, is richer in aluminium oxide than that surrounding other stars. In a recent study, scientists hypothesize these metallic particles may trigger rushes of solar wind.
