VIDEOS: Science Collaborations Find a Way During COVID-19 Pandemic
Even an underground experiment 4,600 feet below a mountain in Central Italy, and a telescope instrument more than a mile high atop an Arizona mountaintop could not escape the impacts of the COVID-19 pandemic. As the virus spread around the world, many laboratories and experiment sites entered a period of partial shutdown and imposed restrictions on site access.

TESS mission discovers massive ice giant
TESS mission discovers massive ice giant
Neptune-sized planet may be remnant core of a much larger planet. The "ice giant" planets Neptune and Uranus are much less dense than rocky, terrestrial planets such as Venus and Earth. Beyond our solar system, many other Neptune-sized planets, orbiting distant stars, appear to be similarly low in density.

Black hole collision may have exploded with light
An international team of astronomers, including researchers from the University of Minnesota, have seen what might amount to the first light ever detected from a black hole merger. When two black holes spiral around each other and ultimately collide, they send out ripples in space and time called gravitational waves.

Black hole swallows much smaller mysterious object
Black hole swallows much smaller mysterious object
A black hole around 23 times the size of the Sun has swallowed a mysterious, much smaller astrophysical object, according to new research announced today by the LIGO and Virgo gravitational wave observatories, including scientists from The Australian National University (ANU).  The gravitational waves from this surprising event were detected by the LIGO and Virgo detectors on 14 August 2019 with the signal coming from a distance of around 800 million light years.

LIGO-Virgo finds mystery object in ’mass gap’
An unusual gravitational wave signal is casting new light on the 'mass gap' between neutron stars and black holes. When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive than this die, they explode in a supernova and leave behind dense, dead remnants of stars called neutron stars.

Gravitational wave scientists grapple with the cosmic mystery of GW190814
A highly unusual gravitational wave signal, detected by the LIGO and Virgo observatories in the US and Italy, was generated by a new class of binary systems (two astronomical objects orbiting around each other), an international team of astrophysicists has confirmed. Scientists from the LIGO and Virgo Collaboration, which includes researchers from the Institute for Gravitational Wave Astronomy at the University of Birmingham, detected the signal, named GW190814, in August 2019.

Cardiff student at the centre of LIGO’s mysterious new discovery
A Cardiff University student has found himself at the centre of a major breakthrough discovery that could potentially help to solve a decades-old mystery. Charlie Hoy, currently in the third year of his PhD and a member of the Laser Interferometer Gravitational Wave Observatory (LIGO) Scientific Collaboration, has played a leading role in deciphering new data observed from the violent collision of two objects roughly 800 million light-years away from Earth.

’Twisted’ sound experiment helps confirm 50-year-old science theory
A 50-year-old theory that began as speculation about how an alien civilisation could use a black hole to generate energy has been experimentally verified for the first time in a Glasgow research lab. In 1969, British physicist Roger Penrose suggested that energy could be generated by lowering an object into the black hole's ergosphere - the outer layer of the black hole's event horizon, where an object would have to move faster than the speed of light in order to remain still.

CfA Scientists Collaborate on New Study to Search the Universe for Signs of Technological Civilizations
Harvard & Smithsonian and the University of Rochester are collaborating on a project to search the universe for signs of life via technosignatures, after receiving the first NASA non-radio technosignatures grant ever awarded, and the first SETI-specific NASA grant in over three decades. Researchers believe that although life appears in many forms, the scientific principles remain the same, and that the technosignatures identifiable on Earth will also be identifiable in some fashion outside of the solar system.

KU Leuven researchers shed new light on solar flares
Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new combination of physical models. Solar flares are explosions on the surface of the Sun that release an enormous amount of energy, equivalent to a trillion 'Little Boy' atomic bombs exploding at the same time.

Surprising Signal in Dark Matter Detector
When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.

A busy signal from outer space
A busy signal from outer space
It beats like a busy signal - one scientists were excited to get. A new study in Nature reports the discovery of a fast radio burst (FRB) that pulses at regular intervals - every 16.35 days - from a nearby galaxy. " Some FRBs are known to repeat, but only irregularly, with cadences ranging from seconds to days," said Laura Newburgh , an assistant professor of physics at Yale involved in the Canadian Hydrogen Intensity Mapping Experiment (CHIME), which produced the research.
