[Russ Maschmeyer] and Spatial Commerce Projects developed WonkaVision to demonstrate how 3D eye tracking from a single webcam can support rendering a graphical virtual reality (VR) display with realistic depth and space. Spatial Commerce Projects is a Shopify lab working to provide concepts, prototypes, and tools to explore the crossroads of spatial computing and commerce.

The graphical output provides a real sense of depth and three-dimensional space using an optical illusion that reacts to the viewer’s eye position. The eye position is used to render view-dependent images. The computer screen is made to feel like a window into a realistic 3D virtual space where objects beyond the window appear to have depth and objects before the window appear to project out into the space in front of the screen. The resulting experience is like a 3D view into a virtual space. The downside is that the experience only works for one viewer.

Eye tracking is performed using Google’s MediaPipe Iris library, which relies on the fact that the iris diameter of the human eye is almost exactly 11.7 mm for most humans. Computer vision algorithms in the library use this geometrical fact to efficiently locate and track human irises with high accuracy.

Webb space telescope’s mid-infrared capabilities allowed scientists to see past gas and dust clouds to observe previously obscured details in faraway galaxies.

A team of researchers has been able to see inside faraway spiral galaxies for the first time to study how they formed and how they change over time, thanks to the powerful capabilities of the James Webb Space Telescope.

“We’re studying 19 of our closest analogs to our own galaxy. In our own galaxy we can’t make a lot of these discoveries because we’re stuck inside it,” says Erik Rosolowsky, professor in the University of Alberta Department of Physics and co-author on a recent paper — published in The Astrophysical Journal Letters.

That’s some tough parenting.

Stars commonly engulf planets, but some can survive and even outlive the star.

Astronomers found compelling evidence that the water in our solar system came from interstellar space. This water around a distant protostar is quite similar to the water found in our solar system, and on Earth.

Astronomers report the discovery of two new exoplanets orbiting a bright sun-like star about 175 light years away. The newfound alien worlds, designated HIP 104,045 b and HIP 104,045 c, were classified as a Jupiter analog and a super Neptune planet, respectively. The finding was detailed in a paper published March 2 on the pre-print server arXiv.

The radial velocity (RV) method to detect an exoplanet is based on the detection of variations in the velocity of the central star, due to the changing direction of the gravitational pull from an unseen exoplanet as it orbits the star. Thanks to this technique, more than 600 exoplanets have been detected so far.

Now, a team of astronomers led by Thiago Ferreira of the University of São Paulo in Brazil, reports the detection of two new exoplanets using the RV method. They observed a solar-type star HIP 104,045 with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph on the 3.6m telescope of the European Southern Observatory (ESO) in La Silla, Chile. The observations, conducted as part of the Solar Twin Planet Search (STPS) program, resulted in the discovery of two massive extrasolar worlds.

On July 21, 1969, Neil Armstrong took that first fateful step onto the Moon. The exact moment occurred just as our planet’s standard universal time hit 2.56 am. But what time was it for Neil?

There’s currently no answer to that question, but with plans in place to inhabit the Moon, that may need to change.

At a recent meeting in the Netherlands, members from space organizations around the world agreed that we need to implement a proper lunar time zone – an internationally accepted common lunar reference time that all future missions can use to communicate and navigate with ease.

This could rethink our view of the world as once-habitable.

Venus has long been discussed as a former ‘ocean world’ like Mars, but a new study in PNAS shows this era may have been short lived.

If there is a social media phenomenon getting some kind of popularity, Meta will try and jump in. We have seen the company copy different kinds of formats ranging from Stories to short videos after seeing the success of other platforms. Now, the Mark Zuckerberg-led company is working on a decentralized text-based app.

Meta confirmed this development in a statement but didn’t give out details about when it plans to release the app.

“We’re exploring a standalone decentralized social network for sharing text updates. We believe there’s an opportunity for a separate space where creators and public figures can share timely updates about their interests,” a Meta spokesperson said.
