There’s no better word for this image of the Sun than Spectacular, which means something impressive, dramatic, or remarkable that creates a spectacle or visual impact. It comes from the Latin word spectaculum, which means a show, spectacle, or public exhibition. Ancient Romans would agree with the word choice if you could somehow show it to them.
Lately, there’s been plenty of progress in 3D printing objects from the lunar regolith. We’ve reported on several projects that have attempted to do so, with varying degrees of success. However, most of them require some additive, such as a polymer or salt water, as a binding agent. Recently, a paper from Julien Garnier and their co-authors at the University of Toulouse attempted to make compression-hardened 3D-printed objects using nothing but the regolith itself.
Images of Mars never cease to amaze. This latest image of NASA’s Curiosity Rover captured by the Mars Reconnaissance Orbiter shows the rover as a dark speck and the end of a long trail of tracks. It was rattling along at a speed of 0.16 km/h across the Gediz Vallis Channel and was headed towards a region that could have been formed by water billions of years ago. The weather on Mars won’t allow the tracks to persist though so they are likely to last for only a few months.
What does the “typical” exosolar system look like? We know it’s not likely to look like our own Solar System, given that our familiar planets don’t include entire classes of planets (Hot Jupiters! Mini-Neptunes!) that we’ve found elsewhere. And our discovery methods have been heavily biased toward planets that orbit close to their host star, so we don’t really have a strong sense of what might be lurking in more distant orbits.

Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III solar radio bursts. With multiple spacecraft now in orbit around the sun, we are in a unique position of observing the propagation of radio emission through the heliosphere from multiple vantage points.

Using the Hubble Space Telescope and an array of other instruments, astronomers have probed supernova wreckage in the Large Magellanic Cloud, the galaxy next door. Continue ReadingHubble helps explore the wreckage of a supernova star explosion in a satellite galaxy of the Milky Way (image)
The Milky Way has more than 30 known satellite galaxies. The Large and Small Magellanic Clouds are the largest and most well-known; other lesser-known ones, like the Sagittarius Dwarf Galaxy, are also on the list. Astronomers think there are many more small satellites that are difficult to detect but essential in understanding the Milky Way. The Vera Rubin Observatory should help astronomers find many more of them.

About 2,600 light-years away, a dead star is sending signals from beyond the grave. Astronomers recently found the strange beacon, which appears to be a pulsar blinking in slow motion — something that shouldn’t be possible. “It’s incredibly exciting to discover such a long-period pulsar,” says Yuanming Wang, a postdoctoral researcher at Swinburne University inContinue reading “Astronomers find a strange pulsar blinking in slow motion” The post Astronomers find a strange pulsar blinking in slow Continue ReadingAstronomers find a strange pulsar blinking in slow motion
