CSIRO has made a detailed radio survey of the southern hemisphere, and discovered a million new galaxies.

Although radio astronomy has been around since the 1930s, it is only in recent years that astronomers have been able to make high-resolution maps of the radio sky. Sky maps are difficult for radio telescopes because radio antennas need to be focused on an extremely small patch of sky to capture images in high resolution. But with modern antennas and computer processing, we can now scan the sky quickly enough to map the heavens in a reasonable amount of time.

In the northern hemisphere, the most detailed radio sky maps have been done by the Very Large Array (VLA). In the 1990s the VLA made the first full-sky surveys of the northern sky. After its upgrade in the 2000s, the observatory began the VLA Sky Survey (VLASS), which has mapped nearly 10 million radio sources.

A 982 megahertz signal dubbed BLC1 (Breakthrough Listen 1) came from the star, as spotted by the Parkes telescope in Australia in April and May 2019. Most tantalizingly, the relatively nearby star system contains a planet dubbed Proxima b, which is about 20 percent larger than Earth and located in the system’s habitable zone, the area where it’s theoretically possible for life to sustain itself.

The news also met with a healthy dose of skepticism. In a statement released today, the SETI Institute commented on the controversial report. The main takeaway: Breakthrough Listen’s discovery is a candidate, not a confirmed signal.

New military goggles give soldiers a unique way to see the battlefield.

Can we morph cities into energy farms? We sure can now! This turbine catches wind from any direction and generates clean energy, even in dense urban areas!

When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.

To more effectively power the electrical grid, locomotives and even electric cars, Lawrence Livermore National Laboratory (LLNL) scientists are turning to diamond as an ultra-wide bandgap semiconductor.

Diamond has been shown to have superior carrier mobility, break down electric field and thermal conductivity, the most important properties to power electronic devices. It became especially desirable after the development of a chemical vapor deposition (CVD) process for growth of high-quality single crystals.

Crucial test for NASA’s SLS ‘mega-rocket’

Part of a giant rocket that will send humans back to the Moon has undergone a critical test.

SMART CONTACT LENSES are coming during this decade, probably within a few years. This company claims it is ready to launch one that will 1) give night vision to the wearer; 2) record video of what you see with your eyes in real time; 3) zoom magnification up to 60 times larger than regular vision, so if you see something far away, you can see what it is; 4) display “augmented” images on your visual field. This means you will be able to see everything normally, BUT can see a text of the weather, or map directions, etc. Eventually, such contact lenses will replace the smart phone, and you will dial, talk, etc, without use of your hands. I would like this to interface with instant language translation, to make learning a language five times faster!

This innovation, called iLens, looks unbelievable on paper. Associated with a smartphone via Bluetooth, this concept would allow you to record your daily memories in video. A telephoto camera embedded in the lens would allow you to zoom digitally up to 60x to enhance your eyesight and discover details invisible to the naked eye. This digital feat would also allow you to see perfectly in the dark.

ILens would also display augmented reality information, for instance to keep a certain distance from others, or practical information regarding air quality or the weather.

Scientists from Nanyang Technological University, Singapore (NTU Singapore), have developed a new way to cure adhesives using a magnetic field.

Conventional adhesives like epoxy which are used to bond plastic, ceramics and wood are typically designed to cure using moisture, heat or light. They often require specific curing temperatures, ranging from room temperature up to 80 degrees Celsius.
