NASA’s Juno discovers a brand new Jupiter. In the year and a half NASA’s Juno spacecraft has been orbiting Jupiter, the science team led by Southwest Research Institute’s Dr. Scott Bolton has discovered that the orange and white bands that characterize Jupiter’s outer atmosphere extend thousands of miles into the gas giant’s atmosphere. The findings are part of a four-article collection about Juno science results in the March 8th edition of the journal Nature.

“With Juno only about a thir...

Asteroids and comets appear to be a much more important supplier of organic molecules on Mars than expected. Until now, astronomers assumed that the organics on Mars mainly came from dust particles from space. Now, computer simulations by an international team of researchers led by Dutch astronomers indicate that one third of the material comes from asteroids and comets.

In 2015, the Mars rover Curiosity discovered remnants of organic molecules on Mars. Scientists wondered how these organic molecules had ended up on Mars...

Notanee Bourassa knew that what he was seeing in the night sky was not normal. Bourassa, an IT technician in Regina, Canada, trekked outside of his home on July 25, 2016, around midnight with his 2 younger children to show them a beautiful aurora borealis. When a thin purple ribbon of light appeared and starting glowing, Bourassa immediately snapped pictures until the light particles disappeared 20 minutes later. Having watched the northern lights for almost 30 years since he was a teenager, he knew this wasn’t an aurora. It was something else.

From 2015 to 2016, citizen scientists—people like Bourassa who are excited about a science field but don’t ne...

This Hubble image reveals the gigantic Pinwheel galaxy, one of the best known examples of “grand design spirals”, and its supergiant star-forming regions in unprecedented detail. The image is the largest and most detailed photo of a spiral galaxy ever released from Hubble. Credit: ESA/NASA

Astronomers have discovered that all galaxies rotate once every billion years, no matter how big they are. The Earth spinning around on its axis once gives us the length of a day, and a complete orbit of the Earth around the Sun gives us a year. “It’s not Swiss watch precision,” said Professor Gerhardt Meurer from the UWA node of the International Centre for Radio Astronomy Research (ICRAR)...
