The rapidly rising global population, sustainability and climate change are among the challenges the agriculture sector faces in the business of producing food. Fortunately, information from satellites can help. A new commercial service – the first in the world – cleverly combines radar data from Copernicus Sentinel-1 and optical data from Copernicus Sentinel-2 to offer daily maps of field-scale crop biomass. Importantly, these maps are completely unimpeded by cloud cover. This new service allows farmers to better monitor and assess the growth of their produce, and, ultimately, make more effective decisions.

Scientists from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere. In a study published in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre for Space Studies (CNES) and

When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups. Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies a

The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe. A new study published in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably

Astronomers at the Center for Astrophysics | Harvard and Smithsonian have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. The findings were published this month in the Astrophysical Journal Letters. Named WASP-62b, the gas giant was first detected in 2012 through the Wide Angle Search for Planets (WASP) South survey. Its atmosphere, however, had

A new international study led by astrophysicist Eric Agol from the University of Washington has measured the densities of the seven planets of the exoplanetary system TRAPPIST-1 with extreme precision, the values obtained indicating very similar compositions for all the planets. This fact makes the system even more remarkable and helps to better understand the nature of these fascinating worlds.

Scientists from the Joint Institute for High Temperatures Russian Academy of Sciences (JIHT RAS) and Moscow Institute of Physics and Technology (MIPT) have experimentally confirmed the presence of an intermediate phase between the crystalline and liquid states in a monolayer dusty plasma system. The theoretical prediction of the intermediate - hexatic - phase was honoured with the Nobel Pr

The research, led by Queen Mary Emeritus Professor Bernard Carr in the School of Physics and Astronomy, together with F. Kuhnel (Munich) and L. Visinelli (Frascati), investigated how these SLABs could form and potential limits to their size. Whilst there is evidence of the existence of supermassive black holes (SMBHs) in galactic nuclei - with masses from a million to ten billion times tha

Even if you weren't a physics major, you've probably heard something about the Higgs boson. There was the title of a 1993 book by Nobel laureate Leon Lederman that dubbed the Higgs "The God Particle." There was the search for the Higgs particle that launched after 2009's first collisions inside the Large Hadron Collider in Europe. There was the 2013 announcement that Peter Higgs and Franco

All four planets orbiting the star HR 8799 were identified via direct imaging - a feat made possible only because of the planets' large sizes and their wide orbits. Planetary systems with these characteristics often have difficulty holding themselves together under all of the gravitational influences involved. But could the HR 8799 system somehow stay intact? The direct imaging technique i
