Solar Orbiter tracks origin of mysterious magnetic switchbacks
The European Space Agency-led Solar Orbiter spacecraft has flown through an S-shaped kink known as a ‘switchback’ in the solar wind’s magnetic field. By fingerprinting the elusive particles within the switchback, Solar Orbiter has traced its origin back to the Sun’s surface and revealed more about solar magnetism – the unruly instigator of dangerous solar storms.
Mars’s oddest cloud may be even odder than we thought
Scientists using the European Space Agency’s Mars Express, in combination with a state-of-the-art meteorological model of the Red Planet, have found that there may be some very exotic physics behind Mars’s most curious cloud.
Webb captures commotion from nebula’s stellar jets
Science begins for Smile
On 23 September, the European-Chinese Smile mission was declared ready to start revealing how Earth responds to the wind of charged particles from the Sun. This follows a busy in-space commissioning period since the spacecraft launched on 19 May and reached its target orbit for science operations on 20 June.
Galaxies in a cosmic house of mirrors
Image: This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in great detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300. The orange galaxies concentrated on one side of the cluster are not actually part of the cluster and are much farther away from us.
Successful Earth flyby improves Juice’s course to Jupiter
The European Space Agency’s Jupiter Icy Moons Explorer (Juice) skimmed the very outer edge of Earth’s atmosphere on 28 September, using the gravity of our home planet to alter its route to Jupiter using very little fuel.
A galaxy spinning out of sync
Image: Though the spiral galaxy in this new image by the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. It’s one of over one thousand galaxies in the Virgo Cluster, the nearest large cluster of galaxies bound together by gravity.
