AI Spots Hidden Solar Storm Signs 9 Hours Early

When we think of weather forecasts, we instinctively think of weather on Earth like rain or shine. However, we rarely consider weather forecasts from outside of the Earth, also called space weather. While space weather often results in the awe-inspiring aurora located at the northern and southern latitudes, we often forget the negative impacts of space weather on our everyday lives. This includes potential disruption of communication satellites or ground stations. The primary conundrum that has eluded researchers is being able to forecast incoming space weather so we can better prepare for its impact. from Universe Today https://ift.tt/pthKa2T via IFTTT

Scientists Melted A Diamond and Cracked a Secret of Ice Giants

Some of the strangest weather in the solar system doesn’t happen on Earth, or even Jupiter’s Great Red Spot - it happens in the interior of the Ice Giants like Neptune and Uranus. Specifically, scientists have long believed that, at certain pressure and temperatures, it literally rains diamonds inside of these planets. And for the first time, scientists have mimicked the process they believe creates that. A new paper by physicists at the Lawrence Livermore National Laboratory (LLNL), published in Nature Physics, resolves a 20 year old scientific mystery, and shows how the same physics that makes it rain diamonds inside Neptune could also help us triple our fusion energy output. from Universe Today https://ift.tt/3sgcjRm via IFTTT

A Greenland Glacier Loses Another Chunk of Ice

The ESA's Sentinel satellites captured a 76 sq. km. chunk of ice breaking off from Greenland's Petermann Glacier. They watched the cracks and deformations happen in real time leading up to the calving. While calving is normal, it's happening more often, and this is another clear sign that the Arctic is rapidly changing due to the warming climate. from Universe Today https://ift.tt/HzQuVNO via IFTTT

New Simulations Show How Galactic Centers Grow Together

Using a state-of-the-art galaxy simulation, a team led by scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) gained new insights into the processes shaping galactic centres across the Universe and the formation history of the Milky Way. from Universe Today https://ift.tt/t5pFs02 via IFTTT

Surface Chemistry Shows Which Massive Stars Have Gained Mass from Binary Companions

Most stars, including massive ones, are in binary pairs. Astronomers think that about 70% of them have gained mass from their companions, but there's been no way to determine which ones have done so. Now, researchers have found a way. from Universe Today https://ift.tt/r7mxVLO via IFTTT

A Distant Stream of Stars May Offer New Clues to Dark Matter

Dark matter continues to challenge astronomers as they work to solve the mystery of this so-far-unseen material that permeates the Universe. It's not that the stuff doesn't exist. It does, but we just can't see it. The only way it can be detected is by its gravitational effects on ordinary matter. A team of researchers led by University of Copenhagen PhD student Julie Kiel Holm has found a stream of stars stretching out more than 3,000 light-years from a globular cluster that appears to have been shaped by dark matter in a distant galaxy. from Universe Today https://ift.tt/k6ygbdz via IFTTT
