Unique solar system views from NASA sun-studying missions
Though they focus on the star at the center of our solar system, three of NASA’s Sun-watching spacecraft have captured unique views of the planets throughout the last several months. Using instruments that look not at the Sun itself, but at the constant outflow of solar material from the Sun, the missions—ESA and NASA’s Solar Orbiter, NASA’s Parker Solar Probe, and…
Hear the strange music of distant planetary system TOI-178
In the animation in this post, the rhythmic movement of newly discovered planets around the star TOI-178 is represented through a musical harmony, created by attributing a note (in the pentatonic scale) to each of the planets. Hear the music of these planets. Source: https://earthsky.org/space/star-system-tio-178-planets-in-resonance-orbits-cheops…
Astronomers unmask cosmic eruptions in nearby galaxies
A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.

ECB’s Christine Lagarde Blasts Bitcoin’s Role In Facilitating Money Laundering
An anonymous reader quotes a report from Bloomberg: European Central Bank President Christine Lagarde took aim at Bitcoin’s role in facilitating criminal activity, saying the cryptocurrency has been enabling “funny business.” “For those who had assumed that it might turn into a currency — terribly sorry, but this is an asset and it’s a highly speculative asset which has conducted some…

Remote sensing data sheds light on when and how asteroid Ryugu lost its water
Last month, Japan’s Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft’s other instruments to reveal new details about the asteroid’s past.

A New Population of Blue Whales Was Discovered Hiding in the Indian Ocean
Weighing up to 380,000 pounds and stretching some 100 feet long, the blue whale — the largest creature to have ever lived on Earth — might at first seem difficult for human eyes and ears to miss. But a previously unknown population of the leviathans has long been lurking in the Indian Ocean, leaving scientists none the wiser, new research suggests….
