NASA Telescopes Reveal Black Hole Tearing Apart Star

Posted by in category: cosmology

Observations from NASA reveal how complex and catastrophic an event it can be when a star gets too close to a black hole, CBS News reported on Wednesday.

Such an event does not occur in a single moment but, according to NASA, can take several months as the black hole’s gravity slowly sucks in the star’s being.

The latest such observation, which took place over a period of more than five months, was watched by multiple telescopes, NASA’s Jet Propulsion Laboratory reported.

X-ray Jet From Black Hole Pointed at Earth — New Discovery — [10]

In this lesson, you will learn about a recent discovery of a black hole interacting with a nearby star and shooting a jet of high energy matter and x-rays in the direction of earth. The signal is called a tidal disruption event, and is named AT2022cmc. It was detected by the Zwicky Transient Facility and subsequent observations in the x-ray region was done by observatories around the world. MIT and the University of Birmingham published the findings in Nature Astronomy. The object is 8.5 billion light years away, and so is the most distant and brightest gamma ray burst ever detected. It is thought that we are looking at the jet of x-rays head on.

Behold! This gorgeous galaxy image merges Hubble and Webb data in stunning detail

Posted by in category: cosmology

NGC 1,566 is a rare bird among galaxies: Gas and dust are still falling into the supermassive black hole at its center, fueling powerful outbursts of radiation that, in shorter wavelengths of light, make the galaxy’s center blaze brighter than all the rest of its stars combined.

Of the thousands of galaxies astronomers have found, cataloged, and studied so far — and the tens of billions in the universe — only about 10 percent have actively-feasting supermassive black holes at their centers. And NGC 1,566 is the second-brightest of these. At 40 million light years from Earth, it’s also one of the closest, making it a prime target for astronomers.

Hubble’s Wide Field Camera captured a near-infrared view of NGC 1,566 back in 2014, which revealed long, swirling arms ablaze with stars and laced with dark strands of interstellar dust. Even in visible and near-infrared light, the galaxy’s core is bright.

Detecting Dark Matter Decay

Posted by in categories: cosmology, particle physics

The first measurements from a newly built gamma-ray observatory have been analyzed for signs of the decay of heavy dark matter, putting a lower limit on the hypothetical particles’ lifetime.

Hubble Telescope Accidentally Discovers a MIND-BLOWING New Galaxy

Posted by in category: cosmology

Humankind is getting very good at looking deep into space: We have already seen two neutron stars colliding, we have encountered mysterious radio blasts and we are about to see, for the first time, the event horizon of a black hole.

But there are still some surprises out there, right here in our own corner of the Universe.

The universe will eventually die, and parallel universes will exist, according to Stephen Hawking’s final research

Posted by in categories: cosmology, space travel

Two weeks before his death, famed scientist Stephen Hawking published a research article predicting parallel universes and along with the end of our own.

Hawking and co-author Thomas Hertog published their results in “A Smooth Exit from Eternal Inflation,” outlining how scientists may also be able to discover other universes using spaceships. According to Hertog, Hawking completed the work on his deathbed, leaving a legacy worthy of the Nobel Prize.

“He has often been nominated for the Nobel and should have won it. Now he never can,” he told the Sunday Times.

Possible Location of the Universe Inside A Fourth-Dimensional Black Hole

Posted by in categories: cosmology, singularity

Our universe is so vast that it appears impossible for anything else to exist. Experts are beginning to suspect that our universe might exist inside a fourth-dimensional black hole.

Our cosmos began as a singularity, a point in space that was endlessly hot and dense. According to researchers at CERN such as James Beecham, black holes in our universe may have the same characteristics as those described by the scientific community.
