Scientists spot flash of light from colliding black holes. But how?

Scientists spot flash of light from colliding black holes. But how?

 

Scientists think they identified two black holes merging that produced a burst of light.

Black holes aren’t supposed to make flashes of light. It’s right there in the name: black holes.

Even when they slam into each, the massive objects are supposed to be invisible to astronomers’ traditional instruments. But when scientists detected a black holes collision last year, they also spotted a weird flash from the crash.

On May 21, 2019, Earth’s gravitational wave detectors caught the signal of a pair of massive objects colliding, sending ripples cascading through spacetime. Later, an observatory called the Zwicky Transient Facility (ZTF) caught a blast of light. As scientists looked at the two signals, they realized both came from the same patch of sky, and researchers started wondering whether they had spotted the rare visible black hole collision.

Did Galaxies Grow from Quantum Static?

Did Galaxies Grow from Quantum Static?

 

A new test could determine whether large-scale cosmic structures have microscopic origins

Did Galaxies Grow from Quantum Static?

Some 13.8 billion years ago, the universe as we know it began in the instant of time we call the big bang. At this moment, very hot and dense energy and matter suffused the cosmos, fueling the expansion of space. In the first split second afterward, many physicists posit, the universe went through a phase of extremely rapid expansion: a process called inflation. One of the most marvelous predictions of this theory is that the arrangement of all the galaxies throughout the universe—the placement of all the “stuff” in the cosmos at the largest conceivable scales—was set by events taking place at the smallest possible level of measurement: the quantum realm. Proponents of this idea, however, have long faced a tricky question:

Can we ever confirm this microscopic origin story if all we can see today are the macroscopic results?

You can help a Mars Rover’s AI learn to tell rocks from dirt – TechCrunch

 

Curiosity doesn’t navigate on its own; there’s a whole team of people on Earth who analyze the imagery coming back from Mars and plot a path forward for the mobile science laboratory. In order to do so, however, they need to examine the imagery carefully to understand exactly where rocks, soil, sand and other features are.

This is exactly the type of task that machine learning systems are good at: You give them a lot of images with the salient features on them labeled clearly, and they learn to find similar features in unlabeled images.

CERN makes bold push to build €21-billion super-collider

CERN makes bold push to build €21-billion super-collider

 

European particle-physics lab will pursue a 100-kilometre machine to uncover the Higgs boson’s secrets — but it doesn’t yet have the funds! 

The decision was unanimously endorsed by the CERN Council on 19 June, following the plan’s approval by an independent panel in March. Europe’s preeminent particle-physics organization will need global help to fund the project, which is expected to cost at least €21 billion and would be a follow-up to the lab’s famed Large Hadron Collider. The new machine would collide electrons with their antimatter partners, positrons, by the middle of the century. The design — to be built in an underground tunnel near CERN’s location in Geneva, Switzerland — will enable physicists to study the properties of the Higgs boson and, later, to host an even more powerful machine that will collide protons and last well into the second half of the century.

eROSITA X-Ray Telescope Captures Hot, Energetic Universe

eROSITA X-Ray Telescope Captures Hot, Energetic Universe | Astronomy | Sci-News.com

 

A new all-sky image from the eROSITA X-ray telescope onboard the Spectrum-Roentgen-Gamma (SRG) space observatory contains over one million objects, about half of which are new to astronomers.

It shows the structure of hot gas in the Milky Way itself, and the circumgalactic medium, whose properties are key to understanding the formation history of our Galaxy.

It also reveals stars with strong, magnetically active hot coronae; binary stars containing neutron stars, black holes or white dwarfs; and spectacular supernova remnants in our own and other nearby galaxies such as the Magellanic Clouds.

ESOblog: Twinkle, twinkle little star, but not on our watch

 

Great blog article from the ESO on adaptive optics – mechanical systems to deform the shape of a mirror to take into account disturbances in the Earth’s atmosphere. The same sort of disturbances that cause stars to “twinkle”. 

Astronomers have turned to a method called adaptive optics. Sophisticated, deformable mirrors controlled by computers can correct in real-time for the distortion caused by the turbulence of the Earth’s atmosphere, making the images obtained almost as sharp as those taken in space. Adaptive optics allows the corrected optical system to observe finer details of much fainter astronomical objects than is otherwise possible from the ground.

This weird quantum state of matter was made in orbit for the first time

By Earl on 15 Jun 2020 No Comments

Bose-Einstein condensates made on the International Space Station could reach temperatures lower than any known in the universe.

On the International Space Station, astronauts are weightless. Atoms are, too.

That weightlessness makes it easier to study a weird quantum state of matter known as a Bose-Einstein condensate. Now, the first Bose-Einstein condensates made on the space station are reported in the June 11 Nature.

The ability to study the strange state of matter in orbit will aid scientists’ understanding of fundamental physics as well as make possible new, more sensitive quantum measurements, says Lisa Wörner of the German Aerospace Center Institute of Quantum Technologies in Bremen. “I cannot overstate the importance of this experiment to the community,” she says.

Scientists create exotic matter on space station to explore the quantum world

 

Scientists have generated an exotic form of matter in the unique microgravity environment aboard the International Space Station and are using it to explore the quantum world, a new study finds.

There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago. When a group of atoms is cooled to near absolute zero, the atoms begin to clump together, behaving as if they were one big “super-atom.”

“A Darker, Deeper Cosmos” –Looking Beyond the Standard Model | The Daily Galaxy

 

Could dark matter particles the size of galaxies exist, or a anti-gravitational force field we call “dark energy” that might be getting stronger and denser, leading to a future in which atoms are ripped apart and time ends? “Our cosmology assumes that most matter comes in a “dark” form that hasn’t yet been detected,” […]

James Webb Space Telescope will “absolutely” not launch in March

By Earl on 11 Jun 2020 No Comments

On Wednesday, the chief of NASA’s science programs said the James Webb Space Telescope will not meet its current schedule of launching in March 2021.

 

Looks like the James Webb Space Telescope is still some time away. Launch in 20210? Who knows!

“This team has stayed on its toes and pushed this telescope forward.”

“We will not launch in March,” said Thomas Zurbuchen, the space agency’s associate administrator for science. “Absolutely we will not launch in March. That is not in the cards right now. That’s not because they did anything wrong. It’s not anyone’s fault or mismanagement.
