2022-02-23 19:38:38 Northrop Grumman wins $341 million Space Force contract to develop a deep-space tracking radar

The contract is for the first of three planned ground-based radar sites to be installed in dispersed locations around the world.
The Space Systems Command’s Space Enterprise Consortium (SpEC) awarded the contract Feb. 22 for the project known as Deep Space Advanced Radar Capability (DARC).
The radar system to be developed by Northrop Grumman will be located in the Indo-Pacific region. It would be one of three planned ground-based radar sites to be installed in dispersed locations around the world.  The company has to complete a prototype by September 2025.
The DARC program was started by the U.S. Air Force in 2017. The Air Force spent $1.5 billion on the Space Fence space surveillance radar to track objects in low Earth orbit. DARC will  track objects in geosynchronous orbit. The three DARC sites are projected to cost $1 billion...Read More

2022-02-20 12:46:50 The gravitational lens effect was predicted by A. Einstein

Back in 1915, as part of the general theory of relativity, he first correctly calculated the angle of deflection of a beam of light in the gravitational field.

By the end of the 20th century several dozens of gravitational lenses were discovered. Some images are indeed in the form of an even or broken ring, which is called the "Einstein ring" or the "Chwolson-Einstein ring".

2022-02-18 20:08:14 First quadruple asteroid system detected

A trio of researchers from the National Astronomical Research Institute of Thailand, Université de Lyon and Sorbonne Université, respectively, has made the first sighting of a quadruple asteroid system—an asteroid with three moons orbiting around it. In their paper published in the journal Astronomy and Astrophysics, Anthony Berdeu, Maud Langlois and Frédéric Vachier, describe how they spotted a third moon around asteroid Elektra and some of its characteristics.
The asteroid Elektra was first seen back in 1873, by astronomer Christian Peters. Since that time, the outer main-belt asteroid has been classified as a G-type—it measures approximately 260 kilometers across and is believed to have a Ceres-like composition. Back in 2003, researchers found that it had a companion moon and then in 2014, a second moon was found. In this new effort, a third moon has been discovered, earning the system a quadruple designation—the first ever observed.

2022-02-17 17:15:18 Faces can unlock smartphones, provide access to a secure building, and speed up passport control at airports, verifying identities for numerous purposes.
An international team of researchers from Australia, New Zealand and India has taken facial recognition technology to the next level, using a person's expression to manipulate objects in a virtual reality setting without the use of a handheld controller or touchpad.
In a world first study led by the University of Queensland, human computer interaction experts used neural processing techniques to capture a person's smile, frown and clenched jaw and used each expression to trigger specific actions in virtual reality environments.
One of the researchers involved in the experiment, University of South Australia's Professor Mark Billinghurst, says the system has been designed to recognize different facial expressions via an EEG headset.

2022-02-16 17:41:25 In the early universe, all previously discovered distant protoclusters like, for example, “The Spiderweb” (left: artist’s impression) are full of vigorously star-forming galaxies. In contrast, the newly-discovered protocluster “MAGAZ3NE J095924+022537” contains a high fraction of red and dead galaxies like the nearby “Coma” cluster (right). The discovery of an ancient cluster containing galaxies which resemble those found in modern clusters was a huge surprise.

2022-02-15 09:30:28 This artist’s impression depicts the formation of a galaxy cluster in the early Universe. The galaxies are vigorously forming new stars and interacting with each other. Such a scene closely resembles the Spiderweb Galaxy (formally known as MRC 1138-262) and its surroundings, which is one of the best-studied protoclusters.
