A few years from now, a small radio telescope on the far side of the moon could help scientists peer into the universe’s ancient past.
The moon instrument, called the Lunar Surface Electromagnetics Experiment-Night (LuSEE-Night), is a pathfinder being developed by the U.S. Department of Energy’s Brookhaven and Lawrence Berkeley National Laboratories, the Space Science Laboratory at the University of California, Berkeley, and NASA’s Science Mission Directorate.
A project to map the earliest structures of the universe has found 15,000 more galaxies in its first snapshot than captured in an entire deep field survey conducted 20 years ago.
The James Webb Space Telescope, the new preeminent observatory in the sky, saw about 25,000 galaxies in that single image, dramatically surpassing the nearly 10,000 shown in the Hubble Space Telescope’s Ultra Deep Field Survey (Opens in a new tab). Scientists say that little piece of the space pie represents just four percent of the data they’ll discover from the new Webb survey by the time it’s completed next year.
“When it is finished, this deep field will be astoundingly large and overwhelmingly beautiful,” said Caitlin Casey, a University of Texas at Austin astronomer co-leading the investigation, in a statement (Opens in a new tab).
Learning that your whole life is a lie while you’re trapped in space is a tough combo.

Sand dunes of many shapes and sizes are common on Mars. In this example, the dunes are almost perfectly circular, which is unusual. Credit: NASA/JPL-Caltech/University of Arizona.

Mars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.
[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.
