SpaceTime Series 27 Episode 122

*The Sun's Most Powerful Solar Flare in Over a Decade

The Sun has unleashed its most powerful solar flare in more than a decade, with a spectacular X9.1 class event. This massive solar flare, part of a pair that erupted just two days apart, was detected by NASA’s Solar Dynamics Observatory. The event sparked strong G3 class geomagnetic storms, causing auroral activity to reach mid-latitudes and triggering deep shortwave radio blackouts. Solar flares, like this one, can have significant impacts on Earth's atmosphere, communications, and power grids.

*Ceres: A Former Ocean World?

New research suggests that the dwarf planet Ceres may have once been an ocean world. The study, published in Nature Astronomy, indicates that Ceres has a dirty icy crust, suggesting a past filled with muddy oceans. Computer simulations reveal that the crust may contain up to 90% ice, challenging previous assumptions of a drier Ceres. The findings are based on data from NASA’s Dawn mission, which observed surface features like volcanoes and glaciers.

*NASA's Europa Clipper Mission

NASA’s Europa Clipper mission is set for launch to explore Jupiter's ice-covered moon, Europa. The mission aims to investigate the moon's potential for life, with a suite of nine scientific instruments on board. These tools will study Europa's icy crust, subsurface ocean, and surface composition. The spacecraft will perform 49 flybys of Europa, gathering data to help scientists understand the moon’s habitability and its potential for hosting life.

SpaceTime Series 27 Episode 121

*A New Planet Discovered Orbiting Barnard's Star

Astronomers have discovered a new exoplanet orbiting Barnard's Star, the closest single star to the Sun. This newly found planet, Barnard b, has about half the mass of Earth and completes an orbit around its host star every three Earth days. Located 5.96 light-years away, Barnard's Star is a small red dwarf in the constellation Ophiuchus. The discovery was made using the European Southern Observatory's Very Large Telescope and has sparked interest due to its low mass and proximity to its star. The study also hints at the existence of three more potential exoplanets in the system, although additional observations are needed for confirmation.

*ESA's Hera Mission Launch

The European Space Agency's Hera mission is set to launch, aimed at exploring the aftermath of NASA's DART mission impact on the asteroid Dimorphos. The mission will provide detailed analysis of the impact site and the asteroid's composition, mass, and structural changes. Hera will also deploy two cubesats, Milani and Juventus, to perform close-up observations and experiments. The mission is crucial for understanding how to protect Earth from potential asteroid threats in the future.

*Spectacular Annular Solar Eclipse

A stunning annular solar eclipse, known as a "ring of fire," has been witnessed by people across the eastern and southern Pacific, as well as parts of South America. The eclipse, which occurs when the Moon is slightly further from Earth, left a bright ring of sunlight visible around the Moon's silhouette. The event was best viewed from Easter Island and parts of Argentina and Chile, with partial views seen in other regions including Bolivia, Peru, and New Zealand.
