Our Sun is known for occasional bursts of energy called solar flares, which can trigger space weather that can disrupt communications and power infrastructure on Earth. But we should really be grateful that we don’t exist around a star that explodes in so-called “superbursts,” which can be 100 to 10,000 times more energetic than even… Read More »
While examining a nearby supernova with NASA’s Fermi gamma-ray space telescope, scientists uncovered a larger mystery in an effort to discover how these stellar explosions fire charged particles called cosmic rays. The team found that the supernova, called SN 2023ixf, was completely devoid of gamma-ray emissions, which should be present when cosmic ray particles are… Read More »
The Jupiter Icy Moons Explorer (JUICE) left Earth a year ago to begin a mission to explore Jupiter’s potential ocean moons Ganymede, Callisto, and Europa in detail. Water is a vital component for life on Earth, so learning more about its distribution on these moons and other moons such as Saturn’s moon Enceladus could tell… Read More »

The record-breaking rain that fell on the United Arab Emirates and Oman this month, triggering deadly floods and chaos, was partly caused by the climate crisis, according to a scientific analysis published on Thursday that points directly to humans burning fossil fuels. A team of 21 scientists and researchers as part of the World Weather… Read More »
Circumstantial evidence shows that: climate change The deadly deluge that inundated Dubai and other parts of the Persian Gulf is getting worse, but scientists have failed to discover the definitive fingerprints of greenhouse gas-induced warming they have seen in other extreme weather events, a new report has found. In just one day last week, parts… Read More »
The Mars Sample Return, a critical NASA mission in the search for life beyond Earth, is in trouble. Its budget has grown from $5 billion to more than $11 billion, and the sample return date could fall from the end of this decade to 2040. The mission will be the first to attempt to return… Read More »
At the end of 2023, astronomers made a surprising discovery in the Orion Nebula. Using the James Webb Space Telescope (JWST), the team found 40 double planetary mass objects, none of which were orbiting a star. These are called Jupiter Mass Binary Objects, or JuMBOs. In short, this discovery directly challenged both the theories of… Read More »
