The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope. RACS will provide a shallow model of the ASKAP sky that will aid the calibration of future deep ASKAP surveys. RACS will cover the whole sky visible from the ASKAP site in Western Australia and will cover the full ASKAP band of 700‑1800 MHz. The RACS images are generally deeper than the existing NRAO VLA Sky Survey and Sydney University Molonglo Sky Survey radio surveys and have better spatial resolution. All RACS survey products will be public, including radio images (with $\sim$15 arcsec resolution) and catalogues of about three million source components with spectral index and polarisation information. In this paper, we present a description of the RACS survey and the first data release of 903 images covering the sky south of declination $+41^\circ$ made over a 288-MHz band centred at 887.5 MHz.

Forward-looking: By combining different wireless techniques, UK researchers achieved record-breaking data transmission speeds. The technology achieved 1 Tbps in lab experiments. Now, it only needs to prove itself in commercially viable applications.

A University College London (UCL) team achieved a nearly one terabit per second data transfer speed over a wireless connection. The world record feat opens the doors to future improvements to high-speed wireless. The researchers used a wide range of frequencies in the electromagnetic spectrum, achieving data rates thousands of times faster than typical UK download speeds over 5G networks.

The recently published study describes an ultra-wideband transmission over the air that combines electronic and photonic-assisted signal generation to send 938 Gbps over a 5-150GHz frequency range. The researchers point out that traditional wireless networks use radio frequencies operating below 6GHz, providing an average speed of 100 Megabits per second over 5G.

Scientist Finds “Evidence” of Another Universe Before This One.

Studies suggest that before our universe, another, previous cosmos existed. They refer to this process as a kind of perpetual cosmic cycle.

A powerful geomagnetic storm caused a spectacular display of light that was visible unusually far from Earth’s poles.

As solar cycle 25 reaches its peak, solar activity has increased significantly. This surge in activity was evident in October 2024 when a remarkable display of the aurora borealis, also known as the northern lights, extended to observers on the ground beyond the Arctic Circle to midlatitude regions.
