A most distant signal
Nearly every galaxy hosts a monster at its center -- a supermassive black hole millions to billions times the size of the Sun. Some of these black holes are particularly active, whipping up stars, dust and gas into glowing accretion disks emitting powerful radiation into the cosmos as they consume matter around them. These quasars are some of the most distant objects that astronomers can see, and there is now a new record for the farthest one ever observed. (2021-01-15)

Most distant quasar discovered sheds light on how black holes grow
A team of astronomers led by the University of Arizona has observed the most distant quasar to date. Fully formed just 670 million years after the Big Bang, the quasar is 1000 times more luminous than the Milky Way. It is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the sun. The discovery provides insight into the formation of massive galaxies in the early universe. (2021-01-12)

Unveiling the double origin of cosmic dust in the distant Universe
Two billion years after the Big Bang, the Universe was still very young. However, thousands of huge galaxies, rich in stars and dust, were already formed. A new study explains how this was possible. Scientists identified the processes behind their evolution and found evidence for a rapid growth of dust due to a high concentration of metals in the distant Universe. The study offers a new approach to investigate the evolutionion of massive objects. (2021-01-11)

Astronomers agree: Universe is nearly 14 billion years old
From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old - give or take 40 million years. (2021-01-04)

Longest intergalactic gas filament discovered
Astrophysicists led by the University of Bonn (Germany) have for the first time observed a gas filament with a length of 50 million light years. Its structure is strikingly similar to the predictions of computer simulations. The observation therefore also confirms our ideas about the origin and evolution of our universe. The results are published in the journal Astronomy & Astrophysics. (2020-12-17)

Can white dwarfs help solve the cosmological lithium problem?
For the first time, lithium has been identified and measured in the atmosphere of a white dwarf. The finding, reported by the University of North Carolina at Chapel Hill, provides clues for what's become of the lithium expected from the Big Bang. (2020-12-17)

When the rains stopped
What can archaeologists tell us about the impacts of climate change on human history? Facets of human life, like breathing, cooking, bathing, agriculture, and engaging with the outdoors, become intertwined with a region's hydroclimate. Interactions with air and water, in turn, influence the ways humans construct and modify their societies. (2020-12-02)

Scientists solve big limitation of stratospheric balloon payloads
Nearly all photons emitted after the Big Bang are now visible only at far-infrared wavelengths. Earth's atmosphere blocks most of this light, so scientists are turning to huge stratospheric balloons to explore it. However, it is quite difficult to cool a telescope the size of a living room to nearly absolute zero while flying it from a balloon. This is where the Balloon-Borne Cryogenic Telescope Testbed comes in. (2020-12-01)

Galaxies in the very early universe were surprisingly mature
Massive galaxies were already much more mature in the early universe than previously expected. This is the conclusion of an international team of astronomers who studied distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA). The result is now published by the National Radio Astronomy Observatory. (2020-10-30)

Surprisingly mature galaxies in the early Universe
When the Universe was only a tenth of its current age its galaxies experienced a growth spurt. It was this period that the scientists in the ALPINE project focused on when they used ESO's ALMA telescope to carry out the first ever large survey of distant galaxies. To their surprise, these galaxies observed in the early stages of their life were far more mature than expected. (2020-10-27)

Anemic star cluster breaks metal-poor record
In a surprising discovery, astronomers using two Maunakea Observatories - W. M. Keck Observatory and Canada-France-Hawaii Telescope (CFHT) - have found a star cluster in the Andromeda Galaxy that contains a record-breaking low amount of metals, calling into question the so-called 'metallicity-floor' for massive globular star clusters. (2020-10-15)

Empathy prevents COVID-19 spreading

Using a new algorithm to model the energy and wavelengths of light coming from almost 7000 nearby galaxies, the researchers succeeded in reconstructing when most of the stars in the Universe formed--in agreement with telescope observations for the first time. (2020-10-06)

ESO telescope spots galaxies trapped in the web of a supermassive black hole
With the help of ESO's Very Large Telescope, astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes formed and grew so quickly. It supports the theory that black holes can grow rapidly within large structures which contain plenty of gas to fuel them. (2020-10-01)

Elements of surprise: neutron stars contribute little, but something's making gold, research finds
Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds. The research also reveals that current models can't explain the amount of gold in the cosmos - creating an astronomical mystery. The work has produced a new-look Periodic Table, showing the stellar origins of naturally occurring elements from carbon to uranium. (2020-09-15)

Big answers from tiny particles
A team of physicists led by Kanazawa University demonstrate a theoretical mechanism that would explain the tiny value for the mass of neutrinos and point out that key operators of the mechanism can be probed by current and future experiments. This work may provide a breakthrough for big philosophical quandaries, including why matter exists. (2020-09-14)

Scientists detect first-of-its-kind 'intermediate-mass' black hole
An international research collaboration including Northwestern University astronomers has witnessed the birth of an ''intermediate-mass'' black hole. This is the first conclusive discovery of an intermediate-mass black hole, an object which has long eluded astronomers. The cosmic event, its energy detected on Earth in the form of gravitational waves, is the most massive black hole merger yet observed in gravitational waves. Two black holes likely collided and merged to create a more massive black hole. (2020-09-02)

Housing First proves cost effective especially for the most-vulnerable homeless group
Canadians spend big money dealing with the consequences of homelessness, but the money spent could be far more effective. According to a new McGill-led analysis, housing homeless people with severe mental illness is even more cost-effective than housing homeless people with moderate needs. A Housing-First strategy aimed at helping these individuals regain and keep permanent housing generates savings equal to about two-thirds of its cost. (2020-08-25)

Shrinking Tasmanian tigers: Resizing an Australian icon
The thylacine, that famous extinct Australian icon colloquially known as the Tasmanian Tiger, is revealed to have been only about half as big as once thought - not a ''big'' bad wolf after all. (2020-08-18)

Small towns have highest risk of intimate partner violence
Despite common perceptions that big cities have more violence, women living in small towns are most at risk of violence from current or former partners. The study analyzed the responses of more than 570,000 women from the National Crime Victimization Survey from 1994-2015. Women from small towns were 27% more likely to be victims of intimate partner violence than women from the center of big cities and 42% more likely than suburban women. (2020-08-06)

Break it down: A new way to address common computing problem
A new algorithm developed in the lab of Jr-Shin Li at the McKelvey School of Engineering at Washington University in St. Louis provides a framework for solving complex linear inverse problems that doesn't require a supercomputer and also enhances security and privacy. (2020-08-04)
