Astronomers tracking the skies around our planet have picked up two very different cosmic companions: a vast interstellar ...

3I/ATLAS is only the third interstellar object ever observed traveling through the solar system, following 1I/'Oumuamua in 2017 and 2I/Borisov in 2019. Each encounter has sparked fascination—and ...

This repository provides code and workflows to test several state-of-the-art vehicle detection deep learning algorithms —including YOLOX, SalsaNext, RandLA-Net, and VoxelRCNN— on a Flash Lidar dataset ...

We took everyday items from ping-pong balls to soda cans and let the ocean decide their fate. The deeper we went, the more brutal the pressure got. Science, chaos, and a few crushed egos later, we ...

On the left is a non-Earth satellite image of TRACERS-2, a spacecraft that is part of a NASA mission to study how the Sun's energy interacts with Earth's magnetic field, collected in August 2025.

Figure 1. Experimental setup showing the center structure (left) carrying the stereo video system and the Ping360 sonar, the six different shape (small cylinder, cube, and big cylinder) and color ...

Scientists using a global array of radio telescopes have detected the universe’s lowest-mass dark object by observing how it warped light through gravitational lensing. The invisible mass, about a ...

Abstract: This paper presents a real-time object detection and tracking algorithm for forward-looking sonar image sequences to enhance navigation and obstacle avoidance algorithms for autonomous ...

Not revised: This Reviewed Preprint includes the authors’ original preprint (without revision), an eLife assessment, public reviews, and a provisional response from the authors. This is a strong paper ...

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which also requires more powerful equipment, and positioning uncertainty that can ...
