New Technique Looks for Dark Matter Traces in Dark Places
New Technique Looks for Dark Matter Traces in Dark Places
Study knocks down some theories for the origin of a mysterious light signature that has puzzled physicists for years So far, the only direct evidence we have for the existence of dark matter is through gravity-based effects on the matter we can see. And these gravitational effects are so pronounced that we know it must make up about 85 percent of all matter in the universe.

Ships' emissions create measurable regional change in clouds
Ships’ emissions create measurable regional change in clouds
A container ship leaves a trail of white clouds in its wake that can linger in the air for hours. This puffy line is not just exhaust from the engine, but a change in the clouds that's caused by small airborne particles of pollution. New research led by the University of Washington is the first to measure this phenomenon's effect over years and at a regional scale.

New data tests 'theory of everything'
New data tests ’theory of everything’
One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a 'theory of everything' that would tie together our understanding of the physical universe. If these particles are eventually detected it would change physics forever Christopher Reynolds Despite having many different versions of string theory circulating throughout the physics community for decades, there have been very few experimental tests.

Path to Razor-Sharp Black Hole Images
Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole. Today, a team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending.

Puzzle about nitrogen solved thanks to cometary analogues
Puzzle about nitrogen solved thanks to cometary analogues
One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogues for comet material. The method on which the study on the detection of ammonium salt is based was developed at the University of Bern.

Iron rain in the evening on a giant exoplanet
Iron rain in the evening on a giant exoplanet
An international team of astronomers, led by UNIGE, has discovered a planet where it rains iron. Thanks to a new instrument conceived by the University of Geneva , Switzerland, and set at the Very Large Telescope (VLT) of the European Southern Observatory (ESO), an international team of researchers, led by UNIGE, has observed a planet featuring iron rains.

Evolutionary elements arrived on Earth much later than thought, say scientists
An international team of geologists, led by scientists at the University of Cologne and including an academic from Cardiff University, say that a large proportion of the elements carbon and nitrogen, as well as the compound water, were not delivered to Earth until very late in the planet's formation.

Astronomers pinpoint rare binary brown dwarf
Astronomers working on ‘first light' results from a newly commissioned telescope in Chile made a chance discovery that led to the identification of a rare eclipsing binary brown dwarf system. The discovery was led by an international team of researchers, including scientists at the University of Birmingham, working on the SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) project.

The axion solves three mysteries of the universe
The axion solves three mysteries of the universe
A hypothetical particle called the axion could solve one of physics' great mysteries: the excess of matter over antimatter, or why we're here at all. According to the Standard Model of particle physics, when our universe was born, the meeting of matter and antimatter should have annihilated each other.

Solved: the mystery of the expansion of the universe
Solved: the mystery of the expansion of the universe
A researcher from the University of Geneva has solved a scientific controversy about the speed of the expansion of the universe by suggesting that it is not totally homogeneous on a large scale. The earth, solar system, entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe.

Scientists Announce Orbital Tilt Measurements in Youngest Planetary Star System Ever
Scientists Announce Orbital Tilt Measurements in Youngest Planetary Star System Ever
Harvard & Smithsonian have, for the first time, measured the orbital tilt of an exoplanet younger than 45 million years. While observing DS Tuc Ab-a recently discovered, young, Neptune-sized planet with an orbital period of eight days-scientists developed new modeling techniques to take stellar obliquity measurements and demographic information about the planet.

Dimming Betelgeuse likely isn't cold, just dusty
Dimming Betelgeuse likely isn’t cold, just dusty
Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova. But astronomers have more benign theories to explain the star's dimming behavior.

What other planets can teach us about Earth
Scientists exploring space are bringing back insights about Earth's deep past, its complicated relationship with life and our planet's future. A composite image shows Earth from the vantage point of a spacecraft in orbit around our planet's moon in October 2015. (Image credit: NASA/Goddard/Arizona State University) Sometimes, you need to leave home to understand it.

Meteorite observation network sets out to catch a falling star
Meteorite observation network sets out to catch a falling star
Imperial and Glasgow scientists are turning their eyes to the skies to track meteorites before they land on UK soil. The team are also looking for volunteers to help them recover the space rocks whenever and wherever they fall. We're looking for volunteers to help us catch these falling stars. These meteorites could help us understand our own planet and solar system - and maybe even the wider universe.

Space weather model gives earlier warning of satellite-killing radiation storms
Space weather model gives earlier warning of satellite-killing radiation storms
Two-day notice lets satellite operators take protective measures against energetic electrons With the expectation that similar patterns may reveal themselves in the future, our model is capable of making predictions by capturing some critical signatures as a precursor to those future events. Youzuo Lin LOS ALAMOS, N.M., March 2, 2020-A new machine-learning computer model accurately predicts damaging radiation storms caused by the Van Allen belts two days prior to the storm, the most advanced notice to date, according to a new paper in the journal Space Weather.

Tracking down the mystery of matter
Tracking down the mystery of matter
Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. In the process they found out that the elementary particle has a significantly smaller electric dipole moment than was previously assumed. With that, it has also become less likely that this dipole moment can help to explain the origin of all matter in the universe.

The force is strong in neutron stars
The force is strong in neutron stars
Study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force - one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force.
