Modeling collisions between argon nuclei and neutrinos from a supernova

Massive stars end their lives in explosions called core-collapse supernovae. These explosions produce very large numbers of weakly interacting particles called neutrinos. Scientists working on the Deep Underground Neutrino Experiment, hosted by Fermilab, are seeking to perform a detailed measurement of supernova neutrinos. This effort could lead to groundbreaking discoveries in particle physics and astrophysics, including the first observation of the transition of a supernova into a neutron star or black hole.

Researchers use laser paintbrush to create miniature masterpieces

Parker Solar Probe sees Venus orbital dust ring in first complete view

NASA's Parker Solar Probe mission has given scientists the first complete look at Venus' orbital dust ring, a collection of microscopic dust particles that circulates around the Sun along Venus' orbit. Though earlier missions have made some observations of Venus' orbital dust ring, Parker Solar Probe's images are the first to show the planet's dust ring for nearly its entire 360-degree span around the Sun.

NASA is hoping to make history early Monday when the Ingenuity Mars Helicopter attempts the first powered, controlled flight on another planet.

NASA's New Horizons reaches a rare space milestone

Roman Space Telescope will also find rogue black holes

In the past, we've reported about how the Roman Space Telescope is potentially going to be able to detect hundreds of thousands of exoplanets using a technique known as microlensing. Exoplanets won't be the only things it can find with this technique, though—it should be possible to find solitary black holes, as well.

When stars get too close to each other, they cast out interstellar comets and asteroids

In October 2017, humanity caught its first-ever glimpse of an interstellar object—a visitor from beyond our solar system—passing nearby the sun. We named it "Oumuamua, and its unusual properties fascinated and confounded astronomers. Less than two years later, amateur astronomer Gennady Borisov found a second interstellar object: a comet-like body that began to disintegrate as it passed within 2 AU of the sun (1 AU equals the distance from Earth to the sun). Where do these interstellar objects come from? How common are they? With a sample size of just two, it's difficult to make any generalizations just yet. On the other hand, given what we know about star formation, we can begin to make some inferences about the likely origins of these objects, and what we are likely to see of them in the future.

Can a new type of glacier on Mars aid future astronauts?

On April 21, 1908, near Earth's North Pole, the Arctic explorer Frederick Albert Cook scrawled in his diary a memorable phrase: "We were the only pulsating creatures in a dead world of ice." These words may soon take on new significance for humankind in another dead world of hidden ice, submerged beneath the red sand of its frigid deserts. This dead world is Mars, and the desert is the planet's mid-latitude region known as Arcadia Planitia.

Why flying a helicopter on Mars is a big deal

Key things to know about NASA's Ingenuity Mars Helicopter

NASA has made history by successfully flying the mini helicopter Ingenuity on Mars, the first powered flight on another planet.

SpaceX has given up trying to catch rocket fairings—fishing them out of the ocean is fine

If there is one driving force in the commercial space industry it is economics. The whole concept of reusable booster rocket emphasizes the importance of getting launch costs down. SpaceX, the company leading the charge in trying to bring launch costs down, doesn't just recover booster rockets however. It also recovers the rocket fairings that hold the payload during launch. SpaceX's original plan was to capture the fairings as they fell back to Earth using specially equipped ships with nets to catch them before they landed in the ocean. Now, however, the company has transitioned to simply fishing fairings out of the ocean after they splash down, and that seems to be working just fine.

How scientists are 'looking' inside asteroids

Asteroids can pose a threat to life on Earth but are also a valuable source of resources to make fuel or water to aid deep space exploration. Devoid of geological and atmospheric processes, these space rocks provide a window onto the evolution of the solar system. But to really understand their secrets, scientists must know what's inside them.

Technology news

Using different teams of robots to model environmental processes

Teams of multiple robots could help to tackle a number of complex real-world problems, for instance, assisting human agents during search and rescue missions, monitoring the environment or assessing the damage caused by natural disasters. Over the past few years, multi-robot systems have proved to be particularly useful for solving problems that involve a distribution over space or time (i.e., allowing agents to cover large distances or monitor processes over time).

Researchers use AI to empower environmental regulators

Like superheroes capable of seeing through obstacles, environmental regulators may soon wield the power of all-seeing eyes that can identify violators anywhere at any time, according to a new Stanford University-led study. The paper, published the week of April 19 in Proceedings of the National Academy of Sciences (PNAS), demonstrates how artificial intelligence combined with satellite imagery can provide a low-cost, scalable method for locating and monitoring otherwise hard-to-regulate industries.

3D deep neural network precisely reconstructs freely-behaving animal's movements

Animals are constantly moving and behaving in response to instructions from the brain. But while there are advanced techniques for measuring these instructions in terms of neural activity, there is a paucity of techniques for quantifying the behavior itself in freely moving animals. This inability to measure the key output of the brain limits our understanding of the nervous system and how it changes in disease.

Tailing new ideas: Cheetah-inspired design enables better robot movement

From lizards to kangaroos, many animals with tails possess an agility that allows them to turn or self-right after a foot slip. Cheetahs demonstrate tremendous precision and maneuverability at high speeds due, in part, to their tails. Translating this performance to robots would allow them to move more easily through natural terrain. However, adding a tail to a robot carries disadvantages like increased mass, high inertia, and a higher energy cost.

A tool for navigating complex computer instructions

We've come a long way since Intel introduced the first microprocessor in 1971. Their 4004 held 2,300 transistors, with today's best chips exceeding billions, harnessing more and more power since their birth.

Mapping performance variations to see how lithium-metal batteries fail

Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles. Using high-energy X-rays, they followed the cycling-induced changes at thousands of different points across the battery and mapped the variations in performance. At each point, they used the X-ray data to calculate the amount of cathode material and its local state of charge. These findings, combined with complementary electrochemical measurements, enabled them to determine the dominant mechanism driving the loss of battery capacity after many charge-discharge cycles. As they recently reported in Chemistry of Materials, depletion of the liquid electrolyte was the primary cause of failure. The electrolyte transports lithium ions between the rechargeable battery's two electrodes (anode and cathode) during each charge and discharge cycle.

Cryptocurrency derivatives markets are booming: study

Markets for cryptocurrency derivatives—contractual side-bets on the future price of cryptocurrencies—have exploded in recent years. On a busy day, over $100 billion in these derivatives are traded, rivaling the daily volume traded in the New York Stock Exchange. What's more, there is evidence that the activity inside these markets may affect the value of cryptocurrencies themselves.
