Map shows where northern lights will be visible tonight in the US

Metro2 days ago

The stunning northern lights might be visible in certain US states for the second night in a row on Monday night.
Also called the aurora borealis, the northern lights may be spotted with the naked eye in some states, with a half dozen of them in the north having the highest chance.
The states most likely to have a view of the lights are Alaska, Michigan, Minnesota, Montana, North Dakota and Wisconsin, according to the National Oceanic and Atmospheric Administration (NOAA).
Other states with a lower likelihood of aurora sightings are Maine, South Dakota, Washington, and the northern parts of Idaho, Iowa, New Hampshire, New York, Vermont and Wyoming.
Auroras form when charged sun particles interact with the Earth's gases in the upper atmosphere.
The sun particles, primarily electrons and protons, strike the upper atmosphere at up to 45million mph, creating the phenomenon.
They appear in the northern hemisphere in a variety of hues including green, pink, and less commonly, violet, blue, red and yellow.
The auroras come in different shapes including patches, streams, arcs and curtains in the night sky.
A rare, severe solar storm occurred last week and weather forecasters issued an alert for it on Sunday. More Trending
Another solar storm appeared to be traveling towards Earth on Monday.
Increased solar activity is also causing the auroras to appear more frequently and father south than in the past.
The auroras cannot be seen during the day, only from after sunset to shortly before sunrise.
They can be seen from up to 1000km away from where they are dancing overhead.

Weatherman warns hurricane forecasts in doubt after DOGE's ‘attack on science'

Florida weatherman John Morales has warned that accurate hurricane predictions may be compromised due to cuts to the National Weather Service and NOAA. Morales cited understaffing (20-40 per cent in central and south Florida NWS offices) and a 20 percent reduction in weather balloon monitoring as factors degrading forecasting quality. Morales expressed concern that having skeleton crews working long shifts during severe weather events could lead to mistakes. Elon Musk, who helped run the Department of Government Efficiency (DOGE), had previously pledged to cut $1 trillion from the federal budget by 30 September. NOAA said it is addressing staffing shortages through temporary duty assignments, reassignment opportunities, and plans to advertise permanent positions.

Super Earth in ‘Goldilocks zone' discovered with new alien-hunting tool – now it will search for more habitable planets

Located in the Lyra constellation, the Super Earth planet completes an orbit of its nearby star every 207.5 days ET PHONE HOME Super Earth in 'Goldilocks zone' discovered with new alien-hunting tool – now it will search for more habitable planets Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) SCIENTISTS have stumbled across a new Super-Earth that orbits inside its star's habitable zone with a new alien-hunting tool. Searching for Earth-like planets - and Earth-like life - is the ultimate goal for planetary science.

An international team of scientists, led by the Yunnan Observatories of the Chinese Academy of Sciences (CAS), have used a new technique to find these potentially habitable worlds. It's called the Transit Timing Variation (TTV) technique - which looks for changes in the predicted transit times of an exoplanet. If the time changes, it could indicate the presence of other unseen planets in the system that are gravitationally influencing the transiting planet. The technique is a good way to detect smaller planets that would otherwise be difficult to find By analysing the TTV signals of Kepler-725b, a gas giant planet in the same system, the team were able to find its hidden sister planet Kepler-725c, according to a new study published in Nature Astronomy. Researchers said the technique offers a promising alternative in the hunt for "Earth 2.0." Kepler-725c has 10 times the mass of Earth and is located in the habitable zone of the sun-like star Kepler-725. It receives roughly 1.4 times the solar radiation than Earth does. Best-ever sign of ALIEN life found on distant planet as scientists '99.7% sure of astounding biological activity signal' Located in the Lyra constellation, the Super Earth planet completes an orbit of its nearby star every 207.5 days. During part of this orbit, the planet enters its star's habitable zone - meaning it could host alien life. Little else is known about the planet so far. It is the first time it has been used to discover a Super-Earth, a type of rocky exoplanet that is larger than Earth but too small to be considered a gas giant like Neptune. Astronomers have relied on alternative techniques to find exoplanets for decades. Like the transit method, where astronomers track how the light from a host star dims when a planet passes in front of it. Or through radial velocity (RV) observations, which is when scientists watch the slight wobble of a star as it interacts with the gravitational pull of an orbiting planet. However, both of these techniques have their flaws and make it difficult to detect planets with long orbital periods. The transit approach, for example, requires a planet's orbit to align exactly with our line of sight from Earth. Whereas the RV method requires extremely high-precision measurements, which makes it harder to find smaller planets. 3 An artist's impression of the Kepler-725 system - the small planet in the lower right is the newly discovered Super-Earth in the habitable zone Credit: Gu Shenghong All you need to know about planets in our solar system Our solar system is made up of nine planets with Earth the third closest to the Sun.

Scientists use giant magnets to solve a 20-year-old dark matter mystery

Physicists are always searching for new theories to improve our understanding of the universe and resolve big unanswered questions. But there's a problem. How do you search for undiscovered forces or particles when you don't know what they look like? Take dark matter. We see signs of this mysterious cosmic phenomenon throughout the universe, but what could it possibly be made of? Whatever it is, we're going to need new physics to understand what's going on. Thanks to a new experimental result published today, and the new theoretical calculations that accompany it, we may now have an idea what this new physics should look like – and maybe even some clues about dark matter. Meet the muon For 20 years, one of the most promising signs of new physics has been a tiny inconsistency in the magnetism of a particle called the muon. The muon is a lot like an electron but is much heavier. Muons are produced when cosmic rays – high-energy particles from space – hit Earth's atmosphere. Roughly 50 of these muons pass through your body every second. Muons travel through solid objects much better than x-rays, so they are useful for finding out what is inside large structures. For example, they have been used to look for hidden chambers in Egyptian and Mexican pyramids; to study magma chambers inside volcanoes to predict volcanic eruptions; and to safely see inside the Fukushima nuclear reactor after it melted down. A tiny crack in physics? In 2006, researchers at Brookhaven National Laboratory in the United States measured the strength of the muon's magnetism incredibly precisely. Their measurement was accurate to roughly six parts in 10 billion. This is equivalent to measuring the mass of a loaded freight train to ten grams. This was compared to a similarly impressive theoretical calculation. When researchers compared the two numbers, they found a tiny but significant difference, indicating a mismatch between theory and experiment. Had they finally found the new physics they'd been looking for? A better experiment To find a definitive answer, the international scientific community started a 20-year programme to increase the precision of both results. The huge electromagnet from the original experiment was loaded onto a barge and shipped down the east coast of the US and then up the Mississippi River to Chicago. There, it was installed at Fermilab for a completely overhauled experiment. Just this morning, researchers announced they had finished that experiment. Their final result for the strength of the muon's magnetism is 4.4 times more precise, at one-and-a-half parts in 10 billion. And better calculations To keep up, theorists had to make sweeping improvements too. They formed the Muon g-2 Theory Initiative, an international collaboration of more than 100 scientists, dedicated to making an accurate theoretical prediction. They computed the contributions to the muon's magnetism from more than 10,000 factors. They even included a particle called the Higgs boson, which was only discovered in 2012. But there was one last sticking point: the strong nuclear force, one of the universe's four fundamental forces. In particular, computing the largest contribution to the result from the strong nuclear force was no easy feat. Antimatter vs supercomputers It was not possible to compute this contribution in the same way as the others, so we needed a different approach. In 2020, the Theory Initiative turned to collisions between electrons and their antimatter counterparts: positrons. Measurements of these electron–positron collisions provided the missing values we needed. Put together with all the other parts, this gave a result that strongly disagreed with the latest experimental measurement. The disagreement was almost strong enough to announce the discovery of new physics. At the same time, I was exploring a different approach. Along with my colleagues in the Budapest-Marseille-Wuppertal collaboration, we performed a supercomputer simulation of this strong contribution. Our result eliminated the tension between theory and experiment. However, now we had a new tension: between our simulation and the electron–positron results which had withstood 20 years of scrutiny. How could those 20-year-old results be wrong? Hints of new physics disappear Since then, two other groups have produced full simulations that agree with ours, and many more have validated parts of our result. We have also produced a new, overhauled simulation that almost doubles our precision (released as a preprint, which has not yet been peer-reviewed or published in a scientific journal). To ensure these new simulations weren't affected by any preconceptions, they were performed 'blind'. The simulation data was multiplied by an unknown number before being analysed, so we didn't know what a 'good' or 'bad' result would be. We then held a nerve-wracking and exciting meeting. The blinding factor was revealed, and we found out the results of years of work all at once. After all this, our latest result agrees even better with the experimental measurement of the muon's magnetism. But others emerge The Muon g-2 Theory Initiative has moved to using the simulation results instead of the electron-positron data in its official prediction, and the hint of new physics seems to be gone. Except … why does the electron–positron data disagree? Physicists around the globe have studied this question extensively, and one exciting suggestion is a hypothetical particle called a 'dark photon'. Not only could the dark photon explain the difference between the latest muon results and the electron–positron experiments, but (if it exists) it could also explain how dark matter relates to ordinary matter.
