A Graveyard of Giant Spacecraft Spins Through Space

  A Graveyard of Giant Spacecraft Spins Through Space After observatories retire, they can still spend hundreds, even millions, of years trailing the Earth.The growing expanse, now hundreds of millions of miles wide, has made it trickier for engineers to operate Spitzer and point it at the right places—the sun, to charge itself; Earth, to transmit data; and the dusky universe beyond, to collect even more. So they’ve decided to junk it.

A monster galaxy that existed about 12 billion years ago has baffled scientists because of the way it lived fast and died young.

The galaxy, known as XMM-2599, formed an immense number of stars by the time the universe was only one billion-years-old.

But a mere eight million years later, it suddenly became inactive, astronomers at the University of California, Riverside, claim – and it is not clear why.

Before the universe had reached two billion years, XMM-2599 had managed to form a mass of more than 300 billion suns, postdoctoral researcher Benjamin Forrest explained in the Astrophysical Journal.

Space-time is swirling around a dead star, proving Einstein right again

  Space-time is swirling around a dead star, proving Einstein right again The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds. That prediction is a phenomenon known as frame dragging, or the Lense-Thirring effect. It states that space-time will churn around a massive, rotating body. For example, imagine Earth were submerged in honey. As the planet rotated, the honey around it would swirl — and the same holds true with space-time.

Astronomers have found an unusual monster galaxy that existed about 12 billion years ago, when the universe was only 1.8 billion years old. University of California - Riverside. " Astronomers discover unusual monster galaxy in the very early universe." ScienceDaily.

Astronomers just discovered a rare monster galaxy that grew rapidly in the universe's early days — and then went quiet surprisingly fast . The newfound giant, known as XMM-2599, lies about 12 billion light-years from Earth, meaning that scientists are seeing the galaxy as it existed when the universe

At its peak, this monster galaxy gave birth to more than 1,000 solar masses a year. By comparison, the Milky Way forms about one new star a year.

Researchers were able to make the detailed measurements and calculate the distance using powerful spectroscopic observational equipment located at the Keck Observatory on Maunakea in Hawaii.

“What makes XMM-2599 so interesting, unusual, and surprising is that it is no longer forming stars, perhaps because it stopped getting fuel or its black hole began to turn on,” said Gillian Wilson, a professor of physics and astronomy.

A question on scientists’ lips is what will become of the galaxy now its heyday is over.

And if Beijing realizes its ambitions in coming years, it won’t be the last time it makes history—and threatens U.S. dominance in space.

Astronomers accidentally discovered the footprints of a monster galaxy in the. The discovery may solve a long-standing question in astronomy , the authors said. Recent studies found that some of the biggest galaxies in the young universe grew up and came of age extremely quickly, a result that

Their research reveals how stars in centre of the Milky Way ‘ live fast and die young ’, shedding light on the formation of disk galaxies . This catastrophic event can form a neutron star or a black hole, and even trigger the formation of new stars. Because of this the astronomers have now worked out that

“We do not know what it will turn into by the present day,” Professor Wilson continued.

“We know it cannot lose mass. An interesting question is what happens around it.

“As time goes by, could it gravitationally attract nearby star-forming galaxies and become a bright city of galaxies?”

The team behind the research have been granted additional time at the observatory to look into some of the mysteries that still remain around XMM-2599.

The Sun's light will become SUPERCHARGED when it dies, making it strong enough to obliterate the Solar System's asteroid belt, study finds - but it won't happen for six billion years .
A new study suggests that when a star's life ends, its luminosity increases ten-thousand-fold and the radiation is strong enough to obliterate the asteroid belt the orbits it into small dust particles.When our Sun dies it will take the Solar System's asteroid belt with it.
