New Radiation Belt Discovered Around Earth Scientists have seen a new radiation belt around Earth, according to a study published in the journal Science. The belt, which is located about 11,900 to 13,900 miles (19,100 to 22,300 kilometers) above the planet's surface, was discovered by NASA's twin Van Allen Probes....
Chandrayaan-3 is a planned third lunar exploration mission by the Indian Space Research Organisation (ISRO). It would consist of a lander and a rover similar to the Chandrayaan-2 but would not have an orbiter. Its propulsion module will behave like a communications relay satellite. The spacecraft is scheduled to be...
Redshift and blueshift are two phenomena that describe how the frequency of light changes when an object is moving relative to an observer. When an object is moving away from an observer, the light from the object is redshifted, which means that the wavelength of the light increases and the...
Deep space networking is the process of communicating with spacecraft that are beyond the orbit of Earth. This is a challenging task because the distance between Earth and these spacecraft can be vast, making it difficult to send and receive signals. The Deep Space Network (DSN) is a worldwide network...
Researchers at the University of Toronto and The Hospital for Sick Children (SickKids) have developed a new method of treating glioblastoma, the most aggressive form of brain cancer. The method, called mechanical nanosurgery, uses magnetic carbon nanotubes (mCNTs) to deliver targeted mechanical force to tumor cells. Glioblastoma is a highly...
The Nancy Grace Roman Space Telescope is a NASA infrared space telescope in development and scheduled to launch by May 2027. It is named after Nancy Grace Roman, the first chief astronomer of NASA. The telescope is designed to study a wide range of astronomical objects, including exoplanets, dark energy,...
Meaning, Process, Requirement - Analog to Digital Converters In a world dominated by technology, have you ever wondered how the digital devices we rely on understand the analog signals from the real world? It's like translating the language of the universe into something our gadgets can comprehend. Enter Analog to...
Cybersecurity is the practice of protecting systems, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It is a broad term that encompasses a wide range of security measures, from physical security to information security. Cybersecurity is important because it protects our personal information, our businesses, and...
Brain mapping is a set of neuroscience techniques predicated on the mapping of (biological) quantities or properties onto spatial representations of the (human or non-human) brain resulting in maps. Brain mapping is a broad term that encompasses a variety of techniques that are used to study the brain. Some of...
A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and oxidizer; that is, both its fuel and oxidizer are gases which have been liquefied and are stored at very low temperatures. These highly efficient engines were first flown on the US Atlas-Centaur and were one of...
