The Gold In Our Galaxy May Be 10 Billion Years Old, Say Scientists

The hundreds of gold-rich stars discovered in our Milky Way galaxy may have come from smaller galaxies that merged 10 billion years ago, according to new simulations by a supercomputer.

Using the ATERUI II supercomputer in the Center for Computational Astrophysics at the National Astronomical Observatory of Japan, scientists at Tohoku University and the University of Notre Dame developed new simulations of galaxy formation with the highest resolution yet.

The paper was published this week in the Monthly Notices of the Royal Astronomical Society.

‘Polluted’ white dwarfs could unveil the secrets of how planetary systems are formed

The idea that planets only develop when a star reaches its maximum size has been challenged by the observation that stars and planets “grow up” together.

Some of the oldest stars in the universe, the building blocks for planets like Jupiter and Saturn start to form when a young star is growing, suggests a new study published on Nov. 14 in the journal Nature Astronomy.

The recent findings indicate that stars and planets ‘grow up’ together, challenging a leading belief that planets only form once a star has reached its final size.

Elon Musk’s Starlink buys ad time on Elon Musk’s Twitter

The employees past and present are calling it a Twitter “takeover.”

Elon Musk, in a move to wrap himself up in a blanket of his own financing, has bought ad space on Twitter. SpaceX bought the ads for Starlink, and they will play on top of the Twitter platform’s feed for one day in Spain and Australia.

In a tweet in reply to another Twitter account Musk said of the deal, “SpaceX Starlink bought a tiny — not large — ad package to test effectiveness of Twitter advertising in Australia & Spain. Did same for FB/Insta/Google,”

Scientists Spot Brightest Energy Burst Ever Detected in Space

Scientists have discovered the brightest energy burst ever detected in space — and Astronomy Twitter is abuzz over the electrifying finding.

As Vice reports, this uber-bright gamma ray burst (GRB), which are huge bursts of energy that occur during major galactic events such as star deaths, was detected by both NASA’s Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory at England’s University of Leicester.

“Brightest GRB ever just dropped,” University of Alabama astrophysicist Marcos Santander tweeted.

Scientists discover massive ‘extragalactic structure’ behind the Milky Way

Astronomers have detected an enormous extragalactic structure hiding in an uncharted region of space far beyond the Milky Way ‘s center.

This phantom region, known as the zone of avoidance, is a blank spot on our map of the universe, comprising somewhere between 10% and 20% of the night sky. The reason we can’t see it — at least with standard visible light telescopes — is because the Milky Way’s bulging center blocks our view of it; the center of our galaxy is so dense with stars, dust and other matter that light from the zone of avoidance gets scattered or absorbed before reaching Earth’s telescopes.

However, researchers have had better luck uncovering the zone’s secrets with telescopes that can detect infrared radiation — a type of energy that’s invisible to human eyes, but powerful enough to shine through dense clouds of gas and dust. Infrared surveys of the zone of avoidance have found evidence of thousands of individual galaxies shining through the cosmic fog, though little is known about the large-scale structures that lurk there.

Fast burst of infrared light opens a way for 3D processing inside semiconductor chips

Researchers from LP3 Laboratory in France developed a light-based technique for local material processing anywhere in the three-dimensional space of semiconductor chips. The direct laser writing of new functionalities opens the possibility to exploit the sub-surface space for higher integration densities and extra functions.

Semiconductors remain the backbone material of the electronics integrated with modern devices such as cellphones, cars, robots and many other intelligent devices. Driven by the continuous need for miniaturized and powerful chips, the current semiconductor manufacturing technologies are facing increasing pressure.

The dominating manufacturing technology, lithography, has strong limitations when addressing these challenges, given its surface processing nature. For this reason, a solution to fabricating structures under the wafer surfaces would be highly desirable so that the full space inside the materials could be exploited.
