Ever since a mysterious interstellar object, since dubbed 3I/ATLAS, was first spotted screaming into our solar system this year, famed Harvard astrophysicist Avi Loeb has been raising the possibility that the interstellar interloper is an “extraterrestrial artifact” that was sent to us by an intelligent alien race. Researchers have broadly come to the consensus that 3I/ATLAS is a comet. Most …

SpaceX is preparing to launch three spacecraft on a first-of-its-kind mission to study the sun’s influence throughout the solar system, from Earth’s atmosphere to the edge of interstellar space. A Falcon 9 rocket is scheduled to lift off from Launch Complex-39A, at NASA’s Kennedy Space Center in Florida, on Sept. 23 at 7:32 a.m. EDT (1132 GMT). Stowed inside Falcon’s …

The powerful belch of material ejected during a solar flare may be way hotter than scientists thought it was. A new mathematical analysis suggests that the engine driving solar flares is far more effective at heating charged particles, or ions, than it is at heating electrons. This could mean that we’ve been underestimating the Sun, since flare temperatures are estimated …

President Donald Trump’s Department of Energy sparked backlash last week after posting on X that “wind and solar energy infrastructure is essentially worthless when it is dark outside, and the wind is not blowing.”   The message echoed recent remarks from Energy Secretary Chris Wright, a longtime oil and gas executive, who defended Trump’s claim that renewable energy is driving up …

On August 24, 2006, our solar system lost a planet. It wasn’t by cataclysmic destruction, but rather by the vote of the International Astronomical Union, which declared that Pluto, considered the solar system’s ninth planet since its discovery in 1930, had been reclassified as a dwarf planet. Just like that, our sun’s planetary community was reduced to a mere eight …

A high-resolution image of the flare taken by Daniel Inouye Solar Telescope in Hawaii – NSF/NSO/AURA via SWNS The clearest pictures ever taken of a solar flare have been captured by the world’s largest solar telescope in Hawaii. The record-breaking images from the Daniel K. Inouye Solar Telescope are the highest-resolution ever attained, and they revealed astonishing details within a …

By definition, scientists don’t know what to expect as they inspect the interstellar object 3I/ATLAS, since it’s only the third object detected from beyond the solar system in human history. But the surprises just keep coming. The mysterious entity, which was first spotted hurtling towards the Sun from far beyond in early July, has fascinated researchers ever since. As Science Alert …
