Salts and Organics Observed on Ganymede’s Surface by NASA’s Juno
NASA’s Juno mission has observed mineral salts and organic compounds on the surface of Jupiter’s moon Ganymede. Data for this discovery was collected by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aboard the spacecraft during a close flyby of the icy moon. The findings, which could help scientists better understand the origin of Ganymede and…

Elon Musk’s Starlink satellites are “leaking” signals
When I was a child in the 1970s, seeing a satellite pass overhead in the night sky was a rare event. Now it is commonplace: sit outside for a few minutes after dark, and you can’t miss them. Thousands of satellites have been launched into Earth orbit over the past decade or so, with tens…

JWST Searches for Planets in the Fomalhaut System
The Fomalhaut system is nearby in astronomical terms, and it’s also one of the brightest stars in the night sky. That means astronomers have studied it intensely over the years. Now that we have the powerful James Webb Space Telescope the observations have intensified. The Fomalhaut system has a confounding and complex dusty disk, including…

James Webb Space Telescope dives deep into the Crab Nebula supernova wreckage (video)
Using the James Webb Space Telescope (JWST), a team of astronomers has captured an unprecedented, ethereal view of the Crab Nebula. This cosmic crustacean, located around 6,500 light-years away in the constellation of Taurus, is the remnant of a supernova first recorded by 11th-century astronomers in 1054. In the modern era of astronomy, the Crab…

Saving open space and history in one Big Bang
“Our whole universe was in a hot, dense state; Then nearly fourteen billion years ago expansion started, wait; The Earth began to cool, the autotrophs began to drool …” If you’re a fan of the Big Bang Theory television series, you probably can sing the rest of the show’s theme song lyrics – which explain, briefly and…

The Crab Nebula Seen in New Light by NASA’s Webb
NASA’s James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 C.E. by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and…
