Scientists search for black holes by looking at x-rays that are released when they"eat" nearby stars. However, when black holes are inactive, this method doesn't work.This time, the researchers looked at stars that orbit invisible (看不见的) objects. These objects,they believe, cannot be ...
However, when blackholes are inactive, this method doesn't work.This time, the researchers looked at stars that orbit(绕……轨道运行)invisible(看不见的) objects. These ob-jects, they believe, cannot be anything but black holes. Aftercalculating(计算) the speed of one particular star in a...
The PIESAT team has also employed artificial intelligence (AI) technology to enhance image analysis efficiency, realizing the real-time monitoring of millimeter-scale deformations in objects like dams, landslides and drainage outlets. In July this year, the four PIESAT satellites then in orbit provid...
The scientists said that a shift toward wetter conditions, perhaps caused by natural shifts in the Earth’s orbit around the sun, led to growth of more trees starting about 2,000 years ago. The “findings suggest that rather than being rainforest hunter-gatherers, or large-scale forest ...

The Goldstone Solar System Radar (GSSR) is a large radar system used for investigating objects in the Solar System. Located in the desert near Barstow, California, it comprises a 500-kW X-band (8500 MHz) transmitter and a low-noise receiver on the 70-m DSS 14 antenna at the Goldstone ...
Does it orbit the Milky Way? Expert Q&A Additional resources Bibliography The Large Magellanic Cloud (LMC) is a dwarf galaxy that is close to the Milky Way. The LMC and its neighbor, the Small Magellanic Cloud (SMC), are so close to our galaxy that we can easily see individual ...
The apparent size of the Sun on Mercury’s surface would be about three times greater than it is on Earth. This image is an artist’s concept of NASA’s MESSENGER spacecraft orbiting Mercury. MESSENGER was a NASA robotic spacecraft that orbited the planet Mercury between 2011 and 2015. ...
