New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is … Read more
The long relationships between stars and the planets around them—including the Sun and the Earth—maybe even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA’s Chandra X-ray Observatory. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers has helped … Read more
This image, taken with Hubble’s Wide Field Camera 3, features the spiral galaxy NGC 4680. Two other galaxies, at the far right and bottom centre of the image, flank NGC 4680. NGC 4680 enjoyed a wave of attention in 1997, as it played host to a supernova explosion known as SN 1997bp. Australian amateur astronomer … Read more
Exploration of ocean worlds has become a hot topic of late, primarily due to their role as a potential harbour for alien life. Moons that have confirmed subsurface oceans garner much of the attention, such as Enceladus and Europa. But they may not be the only ones. Uranus’ larger moons—Miranda, Ariel and Umbriel could potentially … Read more
An international group of collaborators, including scientists from NASA’s Jet Propulsion Laboratory and The University of New Mexico, have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet’s substantial atmosphere, small star, and how fast … Read more
As we all know, the Sun is a giant ball of plasma, and like any plasma, it should support Alfven waves. Alfven waves are waves in a plasma where the ions move in response to tension from a magnetic field. Scientists predicted it 50 years ago until now we had not been able to see them. … Read more
Imagine if your home could be built in days. 3D printing has the potential to build your house from the ground up faster and for less money than a conventional home which means amongst other things, no more smoothing concrete by hand. The technology can physically produce a product of almost any shape based on … Read more
Many experts believe that even at the early stage of True AI, humans will be left behind at some specific task from AI. And I personally believe that AI will surpass us at some point, which is a threat to humanity. Neuralink is Elon Musk‘s answer to the threat artificial intelligence poses to the human … Read more
If I were to ask you whether it’s safe to drink snake venom, you would probably have a very firm answer right away. Either you would automatically say no because snakes wield deadly poisons. Or, if you are a science-savvy, you might unequivocally say yes, because snakes wield venoms, not poisons. Well, I am here … Read more
After several assists from InSight Lander’s arm, the mole appears to be underground. It’s been a real challenge troubleshooting for NASA & DLR from millions of miles away. We still need to see if the mole can dig on its own. There was no way to predict the duracrust and what it meant for the Mole. The future is still uncertain.
Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud colour variations.
