From NFTs to CBDCs, crypto must tackle compliance before regulators do

by JONATHAN CAMILLERI BOWMAN | Cointelegraph

Crypto industry leaders need to self-regulate before inadequate public officials decide to take on the task themselves.

Quantum computing nears a quantum leap

by Bryan Walsh, author of Future |  Axios

A new class of powerful computers is on the brink of doing something important: actual useful work.

Why it matters: Quantum computers have the potential to solve unsolvable problems and break unbreakable encryption, but getting them to the point of reliability remains an enormous engineering challenge.

New study: Women of color in tech aren’t just underrepresented, they’re also undervalued

by Joan C. Williams, Center for Work Life Law | VentureBeat

There’s been a lot of discussion about how we see few women of color in tech because there are few of them in the STEM pipeline. But a forthcoming study my team conducted as part of the Kapor Center’s Women of Color in Computing Collaborative shows that the pipeline is only part of the problem.

With NASA’s Eyes on Asteroids, you can watch all the known near-Earth asteroids and comets as they orbit the Sun. Updated twice daily with the latest tracking data, the web-based application will automatically add new near-Earth object discoveries for you to explore.

Learn more about the growing population of near-Earth objects with NASA’s new 3D real-time web-based application.

Through a new 3D real-time visualization tool, you can now explore the asteroids and comets that approach Earth’s orbital neighborhood – and the spacecraft that visit these objects – with a click or a swipe. NASA’s Eyes on Asteroids brings this data to any smartphone, tablet, or computer with an internet connection – no download required.

Thousands of asteroids and dozens of comets are discovered every single year, some of which – called near-Earth objects (NEOs) – follow orbits that pass through the inner solar system. Now totaling about 28,000, their numbers rising daily, these objects are tracked carefully by NASA-funded astronomers in case any might pose an impact threat to our planet.

The new web-based app depicts the orbits of every known NEO, providing detailed information on those objects. Using the slider at the bottom of the screen, you can travel quickly forward and backward through time to see their orbital motions. The visualization receives twice-daily updates with the latest data, so as soon as a new object is discovered and its orbit is calculated, it’s added to the app.

The profiles for many NEO missions can also be explored. Select the “events” tab to view detailed animated models of those spacecraft and their asteroid or comet encounters. For example, search for NASA’s OSIRIS-REx (short for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft to view an animated re-creation of the mission’s Oct. 20, 2020, Touch-And-Go (TAG) sample collection event. Or view NASA’s Double Asteroid Redirect Test (DART) mission, which recently launched as NASA’s first planetary defense demonstration, and even fast-forward to Sept. 26, 2022, when it will impact the asteroid Dimorphos, the small moonlet of the Didymos binary asteroid system.

“We wanted Eyes on Asteroids to be as user-friendly as possible while telling the stories about humanity’s exploration of these fascinating objects,” said Jason Craig, technical producer of the Visualization Technology Applications and Development team at NASA’s Jet Propulsion Laboratory in Southern California, which developed Eyes. “Every NEO can be found inside the app, as can most of the spacecraft that have visited these objects.”

There’s also plenty of detail on the fascinating science behind NEOs and the importance of tracking potentially hazardous objects. Just select “Learn” for details on topics like asteroid close approaches to Earth or to fly along with the dramatic close approach of asteroid Apophis on April 13, 2029.

While you’re on the topic, choose the “Asteroid Watch” tab to see the next five asteroid close approaches. “We were keen to include this feature, as asteroid close approaches often generate a lot of interest,” said Craig. “The headlines often depict these close approaches as ‘dangerously’ close, but users will see by using Eyes just how distant most of these encounters really are.”

Eyes on Asteroids was developed with support from NASA’s Planetary Defense Coordination Office at the agency’s headquarters in Washington and from JPL’s Center for Near-Earth Object Studies. Eyes gathers its data from JPL’s Solar System Dynamics database, which provides real-time data for the orbits, characteristics, and discovery of most known natural bodies (including NEOs) in our solar system.
