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...

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 ...
that it is a black hole. No other X-ray-quiet black hole is unambiguously known outside our Galaxy. The (near-)circular orbit and kinematics of VFTS 243 imply that the collapse of the progenitor into a black hole was associated with little or no ejected material or black-hole kick. ...
One million planets, all capable of supporting life, could theoretically orbit a supermassive black hole,Space.com reported. Astrophysicist Sean Raymond calculated that a black hole that has a mass 1 million times that of the sun and a ring of nine sun-like stars around it could hold 400 ri...
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 ...
Venus [Sun’s angular diameter: 0.7°] The Sun’s angular diameter in Venus’s sky is about 0.7°. The Sun cannot be seen from Venus’ surface because of its dense, cloudy atmosphere, but this is how our Sun would look like from Venus’ orbit. This image is an artist’s concept of...
Does the Large Magellanic Cloud orbit the Milky Way? Hubble Space Telescope image shows the star cluster NGC 1854, a gathering of red, white and blue stars in the southern constellation of Dorado (The Dolphinfish), located in the Large Magellanic Cloud.(Image credit: ESA/Hubble & NASA) ...
At the same time, the coupling to the scalar filed might change the object's mass during the crossover. The fact that satellites in Earth's orbit (or planets in Sun's orbit) can change their mass and/or lose energy interacting with walls can be used as a new domain wall detection ...
Plutobelongs to a group of objectsthat distantly orbit the sun called theKuiper Belt, where thousands of icy remnants left over from the formation of the solar system linger. Eight of the 10 largest Kuiper Belt Objects have large moons like Charon, Denton said, which means that “kiss and c...
