1st image of our Milky Way’s black hole may be inaccurate, scientists say

NeRD

What does the supermassive black hole lurking at the center of our galaxy look like?It’s a deceptively simple question.  Although our local cosmic abyss, named Sgr A* (short for Sagittarius A*), resides just 26,000 light-years from Earth, it has proven to be a very difficult object to image. This is thanks in part to material whipping around it at near light-speeds. However, after years of trying, scientists with the Event Horizon Telescope (EHT) project succeeded in 2022.The black hole’s silhouette emerged from the shadows, appearing like a fuzzy orange doughnut.…

NASA’s Perseverance rover gets stunning view of big Mars crater from slippery slope (video, photos)

NeRD

NASA’s Perseverance rover took a break from its Mars mountaineering expedition recently to survey its old stomping grounds. The car-sized Perseverance landed on the floor of the 28-mile-wide (45-kilometer-wide) Jezero Crater in February 2021 to hunt for signs of past Mars life and collect dozens of samples for future return to Earth. Perseverance has finished its work in Jezero’s flats and is now scaling the crater’s western rim, on its way to explore new and disparate Mars landscapes. Late last month, however, the rover paused to take in the grand…

A Particular Lenticular Cloud

NeRD

New Zealand’s stunning scenery has famously provided the backdrop for fictional worlds in fantasy films. A unique cloud that forms over the Otago region of the country’s South Island also evokes the otherworldly, while very much existing in reality. NASA/Lauren Dauphin; USGS Landsat 8’s Operational Land Imager acquired this image of an elongated lenticular cloud, locally nicknamed the “Taieri Pet,” above New Zealand’s South Island on Sept. 7, 2024. Lenticular clouds form when prevailing winds encounter a topographic barrier, such as a mountain range. Wind that is forced to flow…

Better Monitoring of the Air Astronauts Breathe Ten weeks of operations showed that a second version of the Spacecraft Atmosphere Monitor is sensitive enough to determine variations in the composition of cabin air inside the International Space Station. Volatile organic compounds and particulates in cabin air could pose a health risk for crew members, and this device increases the speed and accuracy of assessing such risk. Spacecraft Atmosphere Monitor is a miniaturized gas chromatograph mass spectrometer used to analyze the air inside the space station and ensure that it is safe for the…
