What processes are responsible for our Sun’s solar wind, heat, and energy? This is what a recent study published in Physical Review X hopes to address as a team of researchers presented evidence for a newly discovered type of barrier that the Sun exhibits that could help explain the transfer of energy to heat within the Sun’s outer atmosphere. This study has the potential to help scientists better understand the underlying mechanisms for what drives our Sun and what this could mean for learning about other suns throughout the cosmos.

What can binary star systems teach astronomers about the formation and evolution of planets orbiting them? This is what a recent study published in Nature hopes to address as a team of scientists investigated past studies that claimed a specific binary star system could host a planet demonstrating a retrograde orbit, meaning it orbits in the opposite direction of the star’s rotation. This study has the potential to help scientists better understand binary and multiple star systems, specifically the formation and evolution of their planets and what this could mean for finding life beyond Earth.

Scientists from the University of Minnesota have discovered something extraordinary in Jupiter's polar regions that has never been seen before, a completely new type of plasma wave that creates aurora unlike anything we observe on Earth.

For astrobiologists, the search for life beyond our Solar System could be likened to where one would look in a vast desert where there's water. The most intriguing targets are planets called sub-Neptunes, which get their name because they're larger than Earth but smaller than Neptune. What makes them fascinating is that their size and mass suggest they're packed with water but not the kind of water we know.

On August 8, 2024, the NSF Daniel K. Inouye Solar Telescope in Hawaii achieved a historic milestone by capturing the sharpest images ever taken of a solar flare. The unprecedented observations revealed coronal loops in stunning detail. The arches of superheated plasma following the Sun's magnetic field lines were captured at such resolution that it’s possible to see individual structures as narrow as 21 kilometres across.

The ESA's JUpiter Icy Moons Explorer (JUICE) is on its way to conduct detailed studies of Jupiter and its three icy moons, Ganymede, Callisto, and Europa. To pick up speed and reach Jupiter by July 2031, the probe will conduct a gravity-assist maneuver with Venus on Sunday, August 31st. According to the ESA, the mission suffered an anomaly with its communications system, which temporarily severed its connection with Earth. Fortunately, a coordinated response by teams at the ESA's European Space Operations Centre (ESOC) and Airbus (JUICE's manufacturer) restored communications in time for the probe's flyby.

Astronomers have observed the distant active galaxy OJ 287 for many years. It's a BL Lac object, a type of active galactic nuclei known for their extreme variability. They display rapid and pronounced variability in their brightness across multiple wavelengths.

What can the Galactic Habitable Zone (GHZ), which is a galaxy’s region where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets? This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as an international team of researchers investigated a connection between the migration of stars, commonly called stellar migration, and what this could mean for finding habitable planets within our galaxy. This study has the potential to help scientists better understand the astrophysical parameters for finding habitable worlds beyond Earth and even life as we know it.
