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.

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.

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 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.

Yes, conceivably. And if/when we achieve the levels of technology necessary for simulation, the universe will become our playground.

This Encyclopedia Britannica list highlights 10 important dates in the exploration of Pluto, from its discovery in 1930 to the flyby of New Horizons in 2015 and beyond.

Mini instruments are entering their prime.

After DART collided with Dimorphos, scientists want to understand how the asteroid changed. They’ll send the smallest radar to space to glean more information beneath Dimorphos’ surface.

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.
