In the stillness and noise of the M.R.I., I picture what the magnet is doing to my brain. I imagine hydrogen protons aligning along and against the direction of its field. Bursts of radio waves challenge their orientation, generating signals that are rendered into images. Other than the sting of the contrast agent, the momentary changes in nuclear spin feel like nothing. “Twenty-five more minutes,” the radiologist says through the plastic headphones. Usually, I fall asleep.

I’ve had more than 50 scans since 2005, when I received a diagnosis of multiple sclerosis, and I now possess thousands of images of my brain and spine. Sometimes I open the files to count the spinal-cord lesions that are slowly but aggressively taking away my ability to walk. On days my right leg can clear the ground, it feels as if a corkscrew is twisting into my femur. I take halting steps, like a hapless robot, until it’s impossible to move forward. “Maybe in 10 years there will be a pill, or a treatment,” a doctor told me.

For now, even a sustained low fever could cause permanent disability, and medications that treat the disease have left me immunosuppressed, making fevers more likely. I quarantined before it was indicated, and what I miss most now, sheltering in place, are walks through my neighborhood park in Los Angeles with my dog, who gleefully chases the latest bouncy ball I’m hurtling against the concrete. Her current favorite is the Waboba Moon Ball, which comes in highlighter fluorescent yellow and Smurf blue, among other colors. Technically Moon Balls are spherical polyhedrons. They sport radically dimpled surfaces, as if Buckminster Fuller had storyboarded an early pitch for “Space Jam.” Moon Balls are goofy, but they bounce 100 feet.

In these troubled times, enforced home-working is producing remarkable results for physicists and astronomers.

Yes, that’s right. The classic NASA “worm” logo is back! An image of the revived NASA worm logo was released on Twitter by NASA Administrator Jim Bridenstine as well as press release on the NASA.gov website.

NASA explained that original NASA insignia is an iconic symbol widely recognized in the world. The NASA “meatball” logo as many know it by represented patriotic American colors. A red chevron wing piercing a blue sphere(Planet) with white stars, and an spacecraft orbiting. This “meatball” logo was not easy to reproduce with 1970’s technology so the Federal Design Improvement Program introduced in 1975 a new logo, the “worm.”

Some History about the logo

By the beginning of World War I, the United States lagged behind Europe in airplane technology. On March 3, 1915, Congress founded NACA as an independent government agency in response to the perception that the United States was falling behind in aeronautical technology. NACA would report directly to the President with the purpose to catch up. But technology had evolved, and once again the US was falling behind in technology. Russia launched Sputnik. The space race was being lost.

Following the launch of Sputnik, the United States created NASA to catch up in the space race and pull ahead. In order to help spur on a wave of national enthusiasm in support of the nation’s aeronautical, a logo would be needed. The new agency set out to design a new logo and came up with various options for consideration.

Using NASA’s Fermi and Swift spacecraft, astronomers have investigated SGR J1935+2154, the most recurring transient magnetar known to date. The new research sheds more light on the burst properties of this object. The study is detailed in a paper published March 23 on the arXiv pre-print repository.

Magnetars are neutron stars with extremely strong magnetic fields, more than 1 quadrillion times stronger than the magnetic field of Earth. Decay of magnetic fields in magnetars powers the emission of high-energy electromagnetic radiation, for instance, in the form of X-rays or radio waves.

Discovered in 2014, SGR J1935+2154 has a spin period of 3.24 seconds, spin-down rate of 14.3 picoseconds/second, and a dipole-magnetic field with a strength at a level of approximately 220 trillion G, what confirms its magnetar nature. Since its detection, the source experienced more than 100 bursts, occurring almost annually.

With quantum radar, you can map the cosmos with 3D modeling and dwave quantum computer.

A telescope in Arizona will undertake the task after being retrofitted with a high-tech sensor.

NASA’s new spacesuit may not look any different from the one used for spacewalks outside the International Space Station recently, but the US space agency says the suit is designed to achieve more complex tasks than its predecessors. The new suit, which will be worn by astronauts on the Artemis lunar exploration program, is called the Exploration Extravehicular Mobility Unit, or xEMU for short.

While the spacesuit is still under development, its features have been finalised. It’s already being tested underwater, and orbital testing is scheduled for 2023. Take a look:

The obvious drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in a recent issue of Applied Physics Letters, from AIP Publishing, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019–2029.

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe. The infrared semiconductor device faces the sky and uses the temperature difference between Earth and space to produce the electricity.

“The vastness of the universe is a thermodynamic resource,” said Shanhui Fan, an author on the paper. “In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation.”
