The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

Rice University researchers used a microstructure model of radiation-damaged hexagonal boron nitride to help them study the benefits of deep learning techniques in simulating two-dimensional materials to understand their characteristics.

Asteroids, Hydrogen Make Great Recipe for Life on Mars
Data from NASA's Curiosity Mars rover were used in a new paper studying how asteroids impacting the ancient Martian atmosphere could have produced key ingredients to life. Those data were provided by Curiosity's Sample Analysis at Mars instrument.

Curiosity Captured Two Solar Eclipses on Mars
This series of images shows the Martian moon Phobos as it crossed in front of the Sun, as seen by NASA's Curiosity Mars rover on Tuesday, March 26, 2019 (Sol 2359).

An ultrashort spin wave (red) running through a nickel iron layer. Towards the center of the layer, the magnetic direction (blue arrows) swings only up and down in a sort of knot, while the motion in the other parts remains circular -- with opposing sense of magnetic rotation.

In contrast to common silicon-based solar cells, organic photovoltaics (OPVs) involve organic molecules in solar power generation. Materials in OPVs are abundant and processable, cheap and lightweight, and the modules can be made flexible and with tunable properties. The major disadvantage of such materials is that achieving longevity and high performance requires elaborate settings and architectures. Optimized combinations of materials that match the electrodes remain elusive.

This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover's Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see.

The desired nanographenes form like dominoes via cyclodehydrofluorination on the titanium oxide surface. All ‘missing’ carbon-carbon bonds are thus formed after each other in a formation that resembles a zip being closed.

The twist angle formed between atomically thin layers of tungsten disulfide and tungsten diselenide acts as a "tuning knob," turning ordinary semiconductors into an exotic quantum material.
