Milky Way's Supermassive Black Hole Seems to Be Getting Hungrier and Scientists Aren't Sure Why

Milky Way's Supermassive Black Hole Seems to Be Getting Hungrier and Scientists Aren't Sure Why "We have never seen anything like this in the 24 years we have studied the supermassive black hole," researcher Andrea Ghez said.

Most scientists don't believe hairy, snow-loving giant Yetis are real, but astronomers now do believe in a special kind of "cosmic Yeti" galaxy that dates back to the very early universe.

The University of Arizona on Tuesday dropped some colorful words to describe the galaxy: monster, beast, ghostly. "Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given the lack of evidence of their existence," the university said in a statement.

A New Way To Measure Cosmic Distance Could Help Solve A Frustrating Inconsistency About The Universe

A New Way To Measure Cosmic Distance Could Help Solve A Frustrating Inconsistency About The Universe We can add yet another way to measure the universe’s expansion onto the pile of controversy that could perhaps be the most exciting story in cosmology today. The universe is expanding. Measurements of the most distant detectable electromagnetic radiation predict one value for the rate of expansion, but measurements gleaned from nearer objects reveal different values. If the values really are incompatible, it could be a sign that the grand theory currently used to describe the universe’s evolution is broken.

University of Arizona astronomer Christina Williams spotted the ancient galaxy as a faint blob in observations from the Atacama Large Millimeter Array (ALMA) in Chile. She suspected the galaxy "was probably really far away and hidden by clouds of dust."

An animation shows what this galaxy might look like, complete with gas clouds lit up by the activity of star formation.

"We figured out the galaxy is actually a massive monster galaxy with as many stars as our Milky Way, but brimming with activity, forming new stars at 100 times the rate of our own galaxy," said astronomer and study co-author Ivo Labbé with the Swinburne University of Technology in Australia.

The team lead by Williams published its findings on Tuesday in The Astrophysical Journal. The science team estimates the signal ALMA spotted took 12.5 billion years to reach us on Earth. ALMA is operated by the European Southern Observatory and is on a mission to study the origins of galaxies, stars and planets.

The Universe Might Be 2 Billion Years Younger Than We Thought

  The Universe Might Be 2 Billion Years Younger Than We Thought Hey, what's a few billion years between friends? The exact age of the universe has long been up for debate. A new entrant into that debate claims the universe is significantly younger than previous estimates. Scientists used what's known as "gravitational lensing" to track the movement of stars through their gravitational field's distortion, causing them to bend light. The scientists caution that they only had access to two gravitational lenses. There's a large margin for error here.

The observation of this massive galaxy is helping scientists learn more about how such big galaxies formed during the universe's early days. Williams described this hidden galaxy as a "missing link."

It will require more study to find out if this mysterious "Yeti" is actually just one in a pack of cosmic Yetis. This is a question NASA's next-generation (and much delayed) James Webb Space Telescope (JWST) is expected to help answer.

"JWST will be able to look through the dust veil so we can learn how big these galaxies really are and how fast they are growing, to better understand why models fail in explaining them," Williams said. We may discover these distant monsters are quite common.

Mystery Solved in Galaxy Far, Far Away? .
For decades, astronomers have been hunting for a missing neutron star. They may have just found it. For decades, a mystery has consumed the field of astronomy. On February 23, 1987, researchers witnessed the colossal explosion of a star, Sanduleak -69 202, approximately 163,000 light years from Earth in the Large Magellanic Cloud dwarf galaxy. In the wake of supernova 1987A, as it was called, astronomers expected to find a neutron star. Instead, they found nothing but a dense cloud of gas and dust. Due to SN1987A’s mass—about 20 times that of our sun—scientists believed it would form a neutron star.
