NASA’s Webb Takes Its First-Ever Direct Image of Distant World For the first time, astronomers have used NASA’s James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image, as seen through four different light filters, shows how Webb’s powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way to future observations that will reveal more information than ever before about exoplanets. “This is a transformative moment, not only for Webb but also for astronomy generally,” said Sasha Hinkley, associate professor of physics and astronomy at the University of Exeter in the United Kingdom, who led these observations The exoplanet in Webb’s image, called HIP 65426 b, is about six to 12 times the mass of Jupiter, and these observations could help narrow that down even further.

The sounds of a black hole The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole! Source: @NASAExoplanets

Is Civilization on the Brink of Collapse? At its height, the Roman Empire was home to about 30 % of the world’s population, and in many ways the pinnacle of human advancement. Rome became the first city in history to reach one million inhabitants and was a center of technological, legal, and economic progress. An empire impossible to topple, stable and rich and powerful. Until it wasn’t anymore. First slowly then suddenly, the most powerful civilization on earth collapsed. If this is how it has been over the ages, what about us today? Will we lose our industrial technology, and with that our greatest achievements, from one dollar pizza to smartphones or laser eye surgery? Will all this go away too?

⁣⁣Solar storm will hit Earth Today (Aug. 3) High-speed solar winds from a "hole" in the sun's atmosphere are set to hit Earth's magnetic field Today (Aug 3.), triggering a minor G-1 geomagnetic storm. As a G1 geomagnetic storm, it has the potential to cause minor fluctuations in power grids and impact some satellite functions — including those for mobile devices and GPS systems. It will also bring the aurora as far south as Michigan and Maine in the US. Article @EverythingScience

We Must Start Preparing Now For How Climate Change Might End Civilization, Says Report Speculating over humanity's demise is a sport we humans have enjoyed since forever. We build religions on our eschatological hopes, weave fiction out of our dystopian fears, and even write songs about the end of the world as we know it. So it's surprising that in the midst of an escalating global climate crisis, one that impacts everything from the health of individuals to the sustainability of entire ecosystems and their resources, potential global catastrophes are so underexplored. A report published recently in the Proceedings of the National Academy of Sciences argues it's high time we start taking worst-case scenarios seriously and come up with a solid game plan on what happens if – or indeed, when – our current way of life collapses.
