NASA has just announced that it has selected JPL’s Lunar Crater Radio Telescope advanced concept for further research and development. This ultra-long-wavelength radio telescope on the far-side of the Moon has several advantages compared to Earth-based and Earth-orbiting telescopes, including being able to observe the universe at wavelengths greater than 10m (i.e., frequencies below 30MHz) and having the Moon act as a physical shield that isolates the lunar-surface telescope from radio interferences/noises from Earth-based sources.

Have you come across a photo of Mars with spider-like objects? Well, these are not the creepy crawlies you find around your home, but are caused by a phenomenon known as sublimation. That’s right, planetary scientists recreated a machine capable of simulating the Martian atmosphere and discovered that once solid ice came in contact with the warmer sediment of the surface, some of it instantly changed from a solid into gas, resulting in spider-like cracks.

Scientists at Brown University in Rhode Island have created the first wireless brain-computer interface capable of transmitting signals with ‘single-neuron resolution and in full broadband fidelity.’ The BrainGate technology consists of a small transmitter that connects to a person’s brain motor cortex. Participants with paralysis used the system to control a tablet computer and achieved similar typing speeds and point-and-click accuracy as they could with wired systems.

NASA’s Perseverance Mars Rover has just dropped the Ingenuity helicopter ahead of its first flight, but before doing so, it spotted a strange green rock while out exploring. The team is still trying to figure out if it’ something weathered out of the local bedrock or a piece of Mars plopped into the area from a far-flung impact event. For the record, it measures around 6 inches long, and if you look close enough, the row of laser marks where it was zapped becomes clear.

The NASA / ESA Hubble Space Telescope captured this surreal image of the Veil Nebula, and this updated version features new processing techniques that bring out fine details of uts delicate threads and filaments of ionized gas. This image was created using observations taken by Hubble’s Wide Field Camera 3 instrument using five different filters, while the new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (blues), ionized hydrogen, as well as ionized nitrogen (reds).

NASA’s Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) is basically an experimental instrument that stands apart from Perseverance’s primary science. How does it work? Well, this golden cube pulls in the Martian air with a pump and then uses an electrochemical process to separate one oxygen atom from each molecule of carbon dioxide, or CO2, leaving carbon monoxide, or CO, as a byproduct.

Launched in 2018, NASA’s TESS space telescope has discovered over 2,200 candidate planets orbiting bright, nearby stars, including hundreds of “smaller” planets, with many being rocky worlds in some many ways similar to Earth. The data gathered will allow the next generation of space telescopes, like the European Space Agency’s ARIEL, to explore many of these planets in even greater detail to help us better understand exoplanet composition, formation, and migration.

Unlike other hand prosthesis, Esper Bionic’s uses myoelectric technology, which means that it consists of two man sections: the hand (made by the startup) and a socket (manufactured by the clinic). Once fully assembled, the patient’s brain sends signals to the body’s muscles, thus initiating the prosthesis to move accordingly. Muscle sensors installed in arm area transmits this information to the prosthesis. Read more for a video of it in-action and additional information.

Astronomers working on the Event Horizon Telescope (EHT) have just released a new image new image showing the magnetic fields at the edge of the supermassive black hole M87*. It was captured by measuring the polarization of the light emitted by matter in the hot region around the black hole. This marks great progress in understanding just how powerful jets of radiation and matter are emitted by some black holes. Read more for a video and additional information.

When`Oumuamua was first discovered in 2017, some speculated that it could be an interstellar spaceship, but a new study has found that it could be just a remnant of a Pluto-like planet, shaped like a cookie cutter. Arizona State University researchers Alan Jackson and Steven Desch claim that the odd 148-foot object appears to be made of frozen nitrogen, similar to the surface of Pluto and Neptune’s largest moon Triton.
