Center for Astrophysics Scientist and Team First to Measure Wind Speed on an Object Outside the Solar System
Harvard & Smithsonian-today announced the first measurement of atmospheric wind speed ever recorded outside the solar system using a novel technique. Researchers focused their efforts on 2MASS J1047+21, a cool brown dwarf located 33.2 light years from Earth, and clocked wind speeds at 650 meters per second, or 1,450 miles per hour.

New EHT Images Reveal a Writhing Relativistic Jet Deep in the Heart of Black Hole System
Harvard & Smithsonian (CfA), in concert with the Event Horizon Telescope (EHT) Collaboration, have discovered something lurking in the heart of quasar 3C 279: a writhing relativistic jet. Located five billion light-years from Earth in the constellation Virgo, 3C 279 is known for its powerful relativistic jet producing violent variability across the electromagnetic spectrum.

Black Hole Bends Light Back on Itself
You may have heard that nothing escapes the gravitational grasp of a black hole, not even light. This is true in the immediate vicinity of a black hole, but a bit farther out-in disks of material that swirl around some black holes-light can escape. In fact, this is the reason actively growing black holes shine with brilliant X-rays.

Online driving course delivers real life safety results
An online driver training course developed by researchers at The University of Queensland has been shown to reduce speeding and improve driving ability. UQ School of Psychology 's Professor Mark Horswill , along with Dr Andrew Hill, Dr Lisa Buckley, and Associate Professor Marcus Watson, developed the program that teaches drivers how to identify hazards earlier to avoid accidents.

Saturn's 'energy crisis' solved with data from Cassini's final mission
Saturn’s ’energy crisis’ solved with data from Cassini’s final mission
Data gathered by the Cassini spacecraft during the final months of its mission show why Saturn's upper atmosphere is much hotter than expected. Scientists have long wondered why Saturn's upper atmosphere is hotter than would be expected by heating from the Sun alone - a conundrum dubbed Saturn's ‘energy crisis'.

Astronomers Detect First Double Helium-Core White Dwarf Gravitational Wave Source
Harvard & Smithsonian today announced the detection of J2322+0509, a detached binary white dwarf composed of two helium-core stars with a short orbital period. It is the first gravitational wave source of its kind ever detected. "Theories predict that there are many double helium-core white dwarf binaries out there," said Dr. Warren Brown, CfA astronomer and lead author on the study.

Flooding Stunted 2019 Cropland Growing Season, Resulting in More Atmospheric CO2
Severe flooding throughout the Midwest-which triggered a delayed growing season for crops in the region-led to a reduction of 100 million metric tons of net carbon uptake during June and July of 2019, according to a new study. For reference, the massive California wildfires of 2018 released an estimated 12.4 million metric tons of carbon into the atmosphere.

High Altitude Water Cherenkov Observatory tests speed of light
High Altitude Water Cherenkov Observatory tests speed of light
Ultra-high energy gamma rays from the far reaches of the galaxy provide powerful proof that the predictions of relativity, including the constant speed of light, hold to the highest energy extremes yet probed LOS ALAMOS, N.M., March 30, 2020-New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving.

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.
